Resource selection by female white-tailed deer (Odocoileus virginianus) and their offspring during the fawning season can influence survival and recruitment. The selection process in females is thought to represent the balancing of often competing demands to minimize predation risk and maximize resource availability to support the energetic demands of lactation. We used a distance-based approach to examine selection of fawn-rearing areas and locations within fawning areas for 20 radio-instrumented female white-tailed deer on Tensas River National Wildlife Refuge, Louisiana. We also examined selection of vegetative attributes at parturition sites (n = 20) and fawn bed sites (n = 106). Females selected fawn-rearing areas nearer to agriculture than expected given their home ranges, but within their fawn-rearing areas, females were located farther from agriculture and reforestation than expected.

White-tailed deer (Odocoileus virginianus) populations located at the mouth of the Mississippi River are of historical significance as they have been a major source for restocking in Louisiana since the 1960s. Apparent population declines of these deer since the 1990s led the Louisiana Department of Wildlife and Fisheries to initiate a study to gather demographic data on white-tailed deer on the 46,540-ha Pass-a-Loutre Wildlife Management Area (PALWMA). We captured and individually marked 57 deer on PALWMA from 2007 to 2012. We monitored travel corridors using un-baited trail cameras and recorded all sightings of marked and unmarked individuals until 2014. We collected 4,325 photographic observations of white-tailed deer with 340 (8%) resightings of individually marked deer. Estimated apparent annual survival for female and male white-tailed deer was 0.48 ± 0.07 and 0.78 ± 0.06, respectively.

White-tailed deer (Odocoileus virginanus) are the most sought after game species in Kentucky. Deer numbers in southeast Kentucky are relatively low compared to other areas of the state, even after a decade of restrictive doe harvest and prior population supplementation. We estimated survival and assessed cause-specific mortality of a representative deer population in this low-density area within or near the Redbird District of the Daniel Boone National Forest in southeastern Kentucky from January 2014-January 2017. Estimated annual survival for does averaged 0.89 and was relatively high compared to similar studies. Deer-vehicle collisions and poaching caused 13 of 18 (72%) deaths. We recommend longer-term studies at these and other sites in this area to better understand deer population dynamics and their relationship to important habitat components so as to inform regional management of this important game species.

Most state wildlife agencies collect harvest data to inform management decisions. However, these data are typically considered across relatively short time periods and are rarely revisited. We present a case study using historical records to investigate potential agents (i.e., harvest, predation, and forest change) influencing the declining white-tailed deer (Odocoileus virginianus) population in the north Georgia mountains. We used long-term black bear (Ursus americanus) and deer harvest data, and indices of forest stand conditions from 1979-2015 on eight Wildlife Management Areas (WMAs) in the north Georgia mountains. During 1979-2015, harvest of male and female deer declined by 85% and 97%, respectively. Over the same time period, mean yearling male deer body weight increased by 21%, mean antler diameter increased by 62%, and mean antler beam length increased by 92%.

Eastern wild turkeys (Meleagris gallopavo silvestris; hereafter, turkeys) are widely recognized throughout the southeastern United States as a species of ecological, recreational, aesthetic, and economic importance. As a game species, male turkeys are most popularly hunted during spring, a timeframe coinciding with breeding and nesting activities. Given this period's biological importance, wildlife managers are challenged to avoid negative population effects from harvest while simultaneously providing quality hunting opportunities. Biological considerations associated with timing spring turkey seasons include potential effects on productivity from early and high male harvest and intentional or inadvertent illegal female harvest. Turkey hunters often request spring seasons timed to maximize exposure to gobbling activity, but these sociological considerations may conflict with biological objectives.

Management techniques to improve wildlife populations often can affect non-target species indirectly. Supplemental feeding for northern bobwhite (Colinus virginianus) has become a popular management technique to improve bobwhite recruitment and survival, but potential impacts on non-target species such as eastern wild turkey (Meleagris gallopavo silvestris) are unknown. We deployed 111 global positioning systems on wild turkeys on the South Carolina Department of Natural Resources Webb Wildlife Management Area Complex during 2014-2016 to evaluate if supplemental feeding for quail impacted wild turkey movement ecology. Turkeys which used areas where supplemental feeding had occurred maintained larger ranges before, during, and after hunting season. Ranges of individuals that used the treatment area in 2014 before feeding occurred were larger than individuals' ranges that overlapped the treatment area after feeding began, but differences were minimal (<16 ha).

The Mississippi Alluvial Valley (MAV) had extensive bottomland hardwood forests but less than 25% of this area remains forested today. Impounded greentree reservoirs (GTRs), have been managed for wintering waterfowl since the 1930s, and provide a source of aquatic invertebrates and acorns for foraging ducks and other wildlife. However, few studies of invertebrate community-composition, diversity, and biomass have been conducted at regional scales. We collected samples of aquatic invertebrates from three hardwood bottomlands in the MAV and one in the Mississippi Interior Flatwoods region during winters 2008-09 and 2009-10. We compared community composition metrics of aquatic invertebrates between naturally flooded forests (NFF) and GTRs. Five families occurred more frequently in GTRs than NFFs (P < 0.01); these were Asellidae, Chironomidae, Cragonyctidae, Daphniidae, and Sphaeriidae.

Researchers have used playback as an effective survey tool for ornithological research and monitoring, but amateur use is controversial because of potential negative effects on birds. Despite limited peer-reviewed research on this technique, conservation organizations worldwide have limited or banned the use of playback. Some birders use “pishing” (vocal imitation of avian alarm calls) as an alternative to playback. We investigated the effects of simulated birder playback and pishing on the behavior of wintering birds in northern Louisiana. Four experimental treatments were performed at each of six sites: baseline (no birder), control (birder present—no sound), pishing (birder pished five times), and playback (birder played three pre-recorded bird songs). Our order of presentation of each experimental treatment was varied at each site to control for habituation of birds.

Watersnakes serve a variety of important roles in aquatic ecosystems with many species being of conservation interest. The northern water- snake (Nerodia sipedon) has some populations of concern, but is found in a wide variety of aquatic habitats throughout North America. Although previous studies have examined the diet of this typically piscivorous species, research has not addressed whether the northern watersnake is preferentially selecting particular fish as prey. In this study, we sampled snake stomach contents and used Chesson's alpha selection index (αi) to investigate whether northern watersnakes are eating fish families in proportion to their availability or are preferentially selecting or avoiding specific fish families. At the Sloughs Wildlife Management Area in western Kentucky, the northern watersnake fed on fish from six families in 2013 (n = 15) and 2014 (n = 36).

Population projection models are applied tools for considering the potential effects of land and population management alternatives. Incorporating spatially explicit processes and individual dynamics into these models can be important when assessing viability for relatively small populations in patchy habitats. We developed a spatially explicit, individual-based population simulation model (IBM) for gopher tortoises (Gopherus polyphemus) incorporating demographic rates from published studies throughout the range of the species. We then demonstrated this approach's utility for evaluating potential viability under projected forest management with and without tortoise population augmentation on two areas of state-managed property in southern Alabama. Under all scenarios, projected populations declined to local extinction within 100-200 years.

Longleaf pine (LLP, Pinus palustris) has been reduced to 3-5% of its original range, but may be particularly resilient to conditions associated with climate change including drought, severe storms, and increased prevalence of pests. Despite the critical role of LLP in building climate resilient ecosystems, little is known about how landscape managers in the region have considered climate change in planning efforts. We gathered 83 publicly accessible natural resource management plans from the southeastern United States that included management of LLP ecosystems between 1999 and 2016. We used document analysis to identify how plans addressed climate change threats on LLP, considered climate change in identification of LLP ecosystems, and linked climate change to planned conservation actions for LLP ecosystems.

In 2011, the Texas state legislature legalized hand fishing as a harvest method for cat fish in Texas. Although large cat fish (>600 mm total length [TL]) are expected to be vulnerable to this fishing method, little is known about hand fishers or their harvest practices. To help make informed management decisions and better understand how hand fishers compare to other Texas' cat fish anglers, we surveyed hand fishers to collect information on their demographics and fishing activities. Survey respondents (n = 118) were primarily preexisting cat fish fishermen who already utilized other gear types to fish for cat fish; only 5.6% of respondents exclusively hand shed. Despite expressing a willingness to use other gear types, 40% of respondents (n = 47) considered hand fishing their most important fishing activity. Respondents indicated they hand shed a median of 15 days annually, primarily during the spawning period.

Alligator gar (Atractosteus spatula) exhibit many characteristics of a periodic life-history strategy, including extended longevity, late maturity, high fecundity, and variable recruitment success. Observations of alligator gar spawning events indicate that recruitment in inland waters may be linked to spring and summer flood pulses and the availability of floodplain spawning habitats. However, because data have mostly come from observation and not formal experimentation, it is unknown whether these data represent true requirements or if they simply reflect conditions that were easily observed. Therefore, we reviewed existing data regarding alligator gar spawning and early development to draft habitat suitability criteria related to recruitment success and then tested these criteria against historic annual recruitment variability (i.e., year-class strength) in the Trinity River and Choke Canyon Reservoir, Texas.

Coastal rivers can support quality largemouth bass (Micropterus salmoides) fishing, but recruitment failure and habitat availability can influence population size and structure because of the dynamic nature of these systems. Stocking success in coastal river systems has been rarely evaluated. is study examined stocking success of oxytetracycline (OTC) marked F1 intergrade Florida (M.s. oridanus) and northern (M.s. salmoides) fingerling largemouth bass in the tidal Chickahominy River, Virginia. Fish were stocked at a density of 62 fish ha-1 in spring 2006 (mean TL = 54 mm) and 2007 (mean TL=51 mm). We used standardized long-term electro fishing and creel surveys to assess individual cohorts and temporal population trends among various size groups. We determined percent contribution by analyzing otoliths for OTC to differentiate between stocked and wild large- mouth bass.

Fisheries management problems are generally complex because they are socio-ecological systems encumbered by issues of scale, stakeholder conflict, and structural uncertainty with respect to the influence of management on the resource. Consequently, agencies that manage fisheries actively seek employees that can demonstrate problem-solving skills and communicate to a diverse set of stakeholders. To enhance development of critical thinking skills, problem-based learning was incorporated into an undergraduate introductory fisheries class using a structured decision making (SDM) framework. Student teams identified a problem of local, regional, or national significance, then defined the problem's scope and scale and identified decision makers and stakeholders, multiple conflicting objectives, and alternative actions designed to meet objectives.

Urban fisheries provide unique angling opportunities for people from traditionally underrepresented demographics. Lake Raleigh is a 38-ha impoundment located on the North Carolina State University campus in Raleigh. Like many urban fisheries, little is known about angler use and satisfaction or how angling catch rate is related to fish availability in Lake Raleigh. We characterized the recreational fishery and fish assemblage with con- current creel and boat electro fishing surveys over the course of one year. In total, 245 anglers were interviewed on 68 survey days. On average, anglers spent 1.7 h fishing per trip and caught 0.385 fish h-1. A large proportion of anglers (43.9%) targeted multiple species, whereas 36.5% targeted largemouth bass (Micropterus salmoides), 10.0% targeted panfish (i.e., sun shes [Lepomis spp.] and crappies [Pomoxis spp.]), and 9.6% targeted cat fish (Ameiurus spp. and Ictalurus spp.).

Published reports indicate night electrofishing may be superior to day sampling to estimate density and diversity of collected shes in some aquatic habitats. However, because shallow, highly turbid waters characteristic of river floodplains present fish detection, navigation, and safety concerns during night electrofishing, many southeastern floodplain sampling programs have focused on day electrofishing. We used paired day and night samples of shes collected by transect (200 m distance for eight minutes) and point electro fishing (1 minute at four points spaced 25 m apart) to assess potential day electro fishing bias at four sites in the Atchafalaya River floodplain during fall and winter 2013. Analyses compared day and night estimates of overall catch-per-unit e ort (CPUE) of bluegill (Lepomis macrochirus), largemouth bass (Micropterus salmoides), and black crappie (Pomoxis nigromaculatus), as well as species richness and assemblage evenness by electrofishing method.

The Georgia Wildlife Resources Division (WRD) conducted a tagging study from April 2011 to May 2012 to study growth of wild brown trout (Salmo trutta) in the Lake Lanier Tailwater section of the Chattahoochee River. Sampling occurred monthly at four sites and fish were tagged with VI- Alpha tags on nine occasions between April 2011 and March 2012 for subsequent recapture. Follow-up samples in June and December 2012 confirmed a lack of movement between sites by any tagged brown trout that was seen in the previous samples. Growth increments between tagging and recapture events were calculated and used to estimate average length at age. More than 80% of brown trout collected measured between 17.5 and 27.5 cm TL. Brown trout appeared to initially grow rapidly, likely reaching quality size (23 cm total length [TL]) within two years. Growth rapidly slowed, however, as fish approached 30 cm.

Paddlefish (Polyodon spathula) are a commercially-exploited species harvested primarily for their roe. e objectives of this study were to describe population characteristics of paddlefish in the lower Mississippi River (LMR) of Arkansas and use population-simulation so ware to deter- mine the length limit required to prevent recruitment over fishing by maintaining spawning potential ratios (SPR) over 30%. Paddlefish (n = 534) were collected from the LMR in cooperation with commercial fishers during the 2008-2011 commercial seasons. Lengths ranged 150-1095 mm eye-fork length and ages, 2-24 years. Total annual mortality was estimated from catch curves at 28%, and mean instantaneous natural mortality was estimated to be 0.19, conferring an estimated exploitation of 10%. Only 10% of gravid females were under the existing 864-mm minimum-length limit (MLL), but changing the MLL to 889 mm would protect an additional 10%.

Accurate age and growth information is essential in successful management of fish populations and for understanding early life history. We validated daily increment deposition, including the timing of first ring formation, for spotted gar (Lepisosteus oculatus) through 127 days post hatch. Fry were produced from hatchery-spawned specimens, and up to 10 individuals per week were sacrificed and their otoliths (sagitta, lapillus, and asteriscus) removed for daily age estimation. Daily age estimates for all three otolith pairs were significantly related to known age. The strongest relationships existed for measurements from the sagitta (r2 = 0.98) and the lapillus (r2 = 0.99) with asteriscus (r2 = 0.95) the lowest. All age prediction models resulted in a slope near unity, indicating that ring deposition occurred approximately daily.

Effective harvest management for mourning doves (Zenaida macroura) requires information regarding factors affecting harvest. We tested the effects of spinning-wing decoys (SWDs) on mourning dove harvest vulnerability on dove fields in central Tennessee during opening weekend of hunting 2007 and 2008. Use of a SWD did not affect numbers of shots red, doves harvested, doves missed, or doves crippled. Heavy hunting pressure may have limited SWD effects on dove harvest by hunters using them. Use of SWDs does not seem to increase overall harvest in mourning dove populations, so regulations prohibiting these decoys for mourning dove hunting seem unnecessary.

Concentrating hunters on dove fields could place mourning doves (Zenaida macroura) and other ground foraging birds at risk of lead poisoning. We collected soil samples during three time periods (pre-soil disturbance [i.e., disking], post-soil disturbance [disking, roller harrow, planting], and post-hunting / field preparation [i.e., mowing, raking, burning]) to determine if soil disturbance reduced the amount of lead shot potentially available to ground foraging birds in managed dove fields. We also collected soil samples in the woods adjacent to these fields. Disking and site preparation did not have an impact on the number or the mass of lead pellets found on the soil surface and to a depth of 1 cm within the dove fields. More lead pellets were collected in the soil samples in the woods adjacent to dove fields than were collected in the dove fields.

Georgia's Wildlife Resources Division (WRD) provides managed dove fields that are open for public dove hunting. Our goal was to examine public mourning dove hunting demand and opportunity in Georgia along with the spatial and temporal distribution of each. We defined public fields as fields owned or operated by WRD and open to any properly licensed hunter, and we defined public demand as the number of hunters that utilized those fields. We used a hunter survey to estimate the number of public dove hunters, their county of residence, the average number of days afield, and the timing of their hunting activities. We estimated opportunity provided by WRD dove fields in hunter-days for the entire season, by season segment, and by county. In 2015-16, Georgia had 54,679 total dove hunters who averaged 4.43 days a field or 242,226 hunter-days of total demand. Public demand accounted for 33,912 hunter-days, or 14% of total demand.

Knowledge of the relationship between waterfowl hunters and harvest levels may better inform harvest management decisions. We examined frequency of different sizes of daily harvests among duck hunters, and hunters' contributions to duck harvest in the Central Flyway from 1975-1984, 1988-1993, and 2002-2011 using the U.S. Fish and Wildlife Service's Parts Collection Survey. We stratified hunters sampled by the Parts Collection Survey into 10 equal hunter groups based on seasonal harvest. Hunter groups were ranked from 1 to 10, with hunter group 1 representing hunters with the lowest seasonal harvests, and hunter group 10 representing hunters with the highest seasonal harvests. Successful hunters attained the 5-duck (1975- 1984), 3-duck (1988-1993), or 6-duck (2002-2011) daily limit in 8%, 28%, and 13%, respectively, of daily harvests.

Anthropogenic pressure can have significant impacts on how wildlife move and how they use habitats. During 2014-2016, we deployed 41 GPS transmitters on male wild turkeys on the South Carolina Department of Natural Resources Webb Wildlife Management Area (WMA) Complex to evaluate effects of hunting intensity on male wild turkey movement ecology. Daily mean movement distance was 3,254 m day-1, but there was significant variation in our mean estimate (SD = 1,478) with movements ranging from 137 to 14,599 m on any given day. Male wild turkeys slightly decreased their movements in response to hunting intensity, but differences in movement distances were <300m and not biologically significant. We found that the primary driver of male wild turkey movements was neither hunting season timing/intensity nor reproductive period timing.

Wildlife managers rely on accurate information regarding wild turkey habitat selection and use to appropriately structure management activities. We used integrated VHF-GPS transmitters to evaluate fine scale movements and habitat selection of male Rio Grande wild turkeys (Meleagris gal- lapavo intermedia) in south Texas. As our study coincided with the regions second worst recorded drought, we evaluated the influence of supplemental resources (supplemental feeding and managed surface water) on turkey distribution and movements. We deployed eight GPS units on adult male Rio Grande wild turkeys captured in south Texas during spring 2009. We classified land cover into three vegetative categories: bare ground/herbaceous (26%), thorn scrub (69%), and woody riparian (5%).

Technological advances allow researchers to increase the quality and quantity of spatial information gathered for movement ecology and range estimation. We conducted a field experiment to assess accuracy of PinPoint GPS transmitters for use on small avian species using northern bobwhite quail (Colinus virginianus) as our test species. We conducted a series of static tests to evaluate relative impacts of canopy cover across a suite of data collection schedules. We also evaluated GPS units on 6 wild northern bobwhite quail trapped in north-central Texas. Radial error estimates from static tests indicated an overall mean spatial error of 39.7 m (191.7 SD; range 0-4389) between known and estimated locations. e median radial error was 2.68 m with an 85th probability quantile of 6.57 m. Less than 0.08% of locations had radial error >100 m; however, those locations significantly impacted error estimates.

Many of the methods used to estimate white-tailed deer population parameters from camera images are reliant upon the assumption that rates of detectability are similar between both sexes and all age groups of deer. e assumption of equal detectability may not be valid when bait is used to attract deer to survey sites due to physical and behavioral differences between deer groups. We placed trail cameras set at 1-minute time-lapse intervals at randomly selected sites baited with corn inside the Auburn University Deer Research Facility, a 175-ha enclosure containing a captive population of marked white-tailed deer, to investigate temporal and sex-related differences in deer use of baited sites. Surveys were conducted during three 10-day periods (prerut, rut, and postrut) in 2013-2014 to quantify deer use of baited sites (i.e. total number of individual adult deer visiting sites, number of visits by individuals, and duration of visits by individuals to baited sites).

White-tailed deer (Odocoileus virginianus) are one of the most abundant and well-studied ungulates in North America. Few studies, however, have examined how population demography affects the fawning season, which may be influenced by age structure and adult sex ratio of the population. From 2010 to 2013, we used vaginal implant transmitters (VITs) to record the birth date of fawns born within a 174-ha captive facility to elucidate how population demography affects fawning season. We documented an earlier shift in fawning season as male age structure increased from a mean of 2.74 years old in 2010 to 3.92 years old in 2013. Prior to the shift, the mean fawning date was 12 August, and after an increase in population age structure, the mean fawning date was 30 July. An earlier fawning season may be important for neonatal survival, especially in areas of the Southeast where coyotes (Canis latrans) may limit recruitment.

Providing a suffcient quantity of nutritional forage should be an integral component of any white-tailed deer (Odocoileus virginianus) management plan that aims to maximize deer condition and quality. Deer managers generally attempt to meet the nutritional needs of their herd through some combination of habitat management, food plot production, and/or supplemental feed provisioning. However, nutritional demands of deer and forage quality and abundance fluctuate throughout the year, creating nutritional stress periods and a dilemma for managers regarding how to maximize the nutritional plane of their herd while minimizing cost. We measured crude protein availability in naturally occurring deer forages found in a mature pine forest managed with prescribed fire and Ladino clover food plots during three nutritionally stressful periods for deer on a 259-ha white-tailed deer enclosure located in east-central Alabama.

An understanding of black bear (Ursus americanus) population trends and cause-specific mortality is needed to direct management decisions in northern Georgia given an increasing human population. Therefore, we evaluated black bear population trends and mortality sources across 26 counties and 18 Wildlife Management Areas in northern Georgia from 1979-2014. We collected harvest data from 6,433 individuals during the study period. Using age-at-harvest data, population reconstruction illustrated an increasing trend in the bear population for both males (λ = 1.113) and females (λ = 1.108). Bait station indices reflected a similar increase in the bear population based on increased visitation over time (min: 12.3% visitation in 1983; max: 76.7% visitation in 2009). Bear-vehicle mortalities also increased from 1986-2014 and were greater for males relative to females, especially males ≤2 years old.

Determining population trends for many aquatic species is problematic for most resource agencies because little or no historical information is available on population size nor are resources available for contemporary population estimates. Managers often only have available to them presenceabsence data collected by qualitative surveys conducted at intermittent intervals. Changes in naïve occupancy can be used to detect population trends. Naïve occupancy is the ratio of number of sites where a species is detected to total number of sites surveyed, without correcting for imperfect detection. Herein, we present ways to conduct analyses for measuring changes in naïve occupancy using presence/absence data from multiple sources. Required elements include showing measures of uncertainty and statistical analysis (including power analysis). These data can effectively be used to determine population trends for many species in a cost effective and statistically rigorous manner.

Accurate age and growth information is essential for a complete knowledge of life history, growth rates, age at sexual maturity, and average life span in fishes. Alligator gar are becoming increasingly managed throughout their range and because this species spawns in backwater flooded areas, their offspring are prone to stranding in areas with limited prey, potentially affecting their growth. Because fish growth is tightly linked with otolith growth and annulus formation, the ability to discern marks not indicative of annuli (age checks) in alligator gar would give managers some insight when estimating ages. Previous studies have suggested that checks are often present prior to the first annulus in otoliths of alligator gar, affecting age estimates. We investigated check formation in otoliths of alligator gar in relation to growth and food availability.

Lake Hickory is a 1660-ha impoundment in western North Carolina with a historically popular black crappie (Pomoxis nigromaculatus) fishery. Beginning in 2000, North Carolina Wildlife Resources Commission (NCWRC) trapnet-survey data suggested a decline in black crappie catch rates which was also associated with increased angler complaints. In an effort to improve the black crappie population, the NCWRC began an experimental stocking program in 2007. From 2007 to 2012, black crappie fingerlings were marked with oxytetracycline (OTC) and stocked annually into Lake Hickory. Annual assessments of initial poststocking survival of OTC-marked fish (79%-98%) and OTC mark efficacy (96%-100%) were high. Black crappie were collected using trapnets set in the fall during 2008-2012. All captured black crappie were aged, and otoliths from fish in the 2007-2011 year classes were examined for an OTC mark. Year-class contributions ranged from 0%-95%.

Spotted bass (Micropterus punctulatus) provide popular recreational fisheries in southeastern U.S. streams. We studied spotted bass population structure and diet from wadeable (< 1 m deep on average, n = 174, 21 sites) and non-wadeable (n = 498, 32 sites) reaches of the Lake Pontchartrain Basin in Mississippi and Louisiana to determine if populations should be managed separately by stream size. Sampling occurred April-November 2009-2012 by hook-and-line angling, boat-mounted electrofishing, and seines. Size structure was similar between stream type and with few quality-sized fish (PSD ≤ 24). Spotted bass relative weight (W_r) was higher in non-wadeable streams (mean W_r = 91) than in wadeable streams (mean W_r = 85). Larger spotted bass (> 200 mm TL) consumed more crayfish and fish, other vertebrates, and multiple types of aquatic and terrestrial insects by number.

Coastal ecosystems are dynamic and productive areas that are vulnerable to effects of global climate change. Despite their potentially limited spatial extent, submerged aquatic vegetation (SAV) beds function in coastal ecosystems as foundation species, and perform important ecological services. However, limited understanding of the factors controlling SAV distribution and abundance across multiple salinity zones (fresh, intermediate, brackish, and saline) in the northern Gulf of Mexico restricts the ability of models to accurately predict resource availability. We sampled 384 potential coastal SAV sites across the northern Gulf of Mexico in 2013 and 2014, and examined community and species-specific SAV distribution and biomass in relation to year, salinity, turbidity, and water depth.

The middle Trinity River in Texas supports one of the premier trophy alligator gar (Atractosteus spatula) fisheries in the world. Published data on alligator gar life history and population characteristics are sparse, yet these data are needed to inform conservation and management. Using data from over 850 fish collected between 2007 and 2014, we described the size structure, population abundance, angler exploitation, and vital rates of this unique population. Collection of fish relied heavily on angler cooperators and included a three-year mark-recapture effort and the removal of sagittal otoliths from fish harvested by bow anglers. Size structure and population abundance data revealed why this population supports such a popular fishery. Size structure was broad (fish ranged from 46 to 241 cm) and trophy-sized alligator gar (> 180 cm) comprised more than 23% of the sample.

The New River crayfish, (Cambarus chasmodactylus), was described in 1966 from the East Fork of the Greenbrier River, West Virginia, and historically occurred throughout the New River Basin from the Greenbrier River sub-basin in West Virginia, upstream through Virginia, and into the headwaters of the South Fork New River in North Carolina. The New River crayfish was part of a federal listing species petition in 2010 and it is currently being evaluated for listing as either threatened or endangered by the U.S. Fish and Wildlife Service under the Endangered Species Act. In order to understand the current distribution and status of this species, a range-wide assessment was undertaken by various organizations and agencies in West Virginia, Virginia, and North Carolina. Biological information was summarized, including species description, habitat use, life history, and current distribution. All historical and recent collections were compared and spatially displayed using GIS software.

Texas Parks and Wildlife Department stocks Toledo Bend Reservoir annually with fingerling Florida largemouth bass (Micropterus salmoides floridanus). Studies suggest that largemouth bass stockings often result in variable and low contributions to cohort abundance. We explored effects of aquatic vegetation on stocking success of fingerling Florida largemouth bass marked with a pelvic fin clip in three species of aquatic vegetation (hydrilla Hydrilla verticillata, coontail Ceratophyllum demersum, and Eurasian watermilfoil Myriophyllum spicatum) in Toledo Bend Reservoir. Stocking sites received 10,000 fingerlings (mean total length = 35 mm) and consisted of 2 km of contiguous habitat. Study sites were stocked in May-June 2010 (n = 6) and May-June 2013 (n = 5) and sampled with electrofishing at 3 weeks and 20 weeks post-stocking.

The lower Trinity River and Trinity Bay in Texas represent the southern limit of the native range of striped bass (Morone saxatilis). Life-history traits of fishes in the northern hemisphere often vary with latitude, with southern populations exhibiting faster growth, earlier age at maturity, reduced longevity, and higher mortality than northern populations. At this southern limit, water temperatures in the Trinity River often exceed reported tolerances for striped bass. We evaluated the likelihood that this fringe striped bass population can persist by examining their life history characteristics, their movements, and the occurrence of thermal refuges in the lower Trinity River. Spawning adult striped bass were collected from 2006 to 2011 to describe life-history characteristics, and ultrasonic telemetry was used from 2008 to 2010 to evaluate movements, and identify thermal refuges.

The Texas Parks and Wildlife Department (TPWD) began the ShareLunker program (currently sponsored by Toyota) in 1986 to promote public involvement in the management of trophy largemouth bass (Micropterus salmoides; LMB) fisheries in Texas. The program provides anglers an opportunity to donate trophy LMB (≥ 5.9 kg) to a selective breeding and stocking program managed by TPWD, with the goal of increasing the production of trophy-sized fish in Texas reservoirs. Although the program was known to be successful at promoting trophy LMB fishing in Texas, it was not known whether selective breeding results in growth advantages and subsequent increases in the likelihood of producing trophy-sized LMB. We assessed the efficacy of the Toyota ShareLunker program by comparing length and weight of age-4 ShareLunker LMB stocked as fingerlings with age-4 naturally produced resident LMB in six small impoundments.

The Grandfather Mountain crayfish (Cambarus eeseeohensis) was described in 2005 from the Linville River in western North Carolina and considered to be endemic to the mainstem Linville River upstream of Linville Falls. Because of its limited distribution and the presence of non-native crayfish in the Linville River watershed, this species was considered imperiled. However, there has been limited survey effort for Grandfather Mountain crayfish and therefore the extent and nature of threats to persistence of the species were mostly unknown. We conducted surveys (n = 41) in 2011 throughout the Linville River watershed and surrounding watersheds to better determine the distribution of the Grandfather Mountain crayfish and assess impacts of exotic crayfishes on this species. We also conducted an evaluation of land ownership and water quality classifications to determine what protections were currently available for conservation of this crayfish.

The yellow bass (Morone mississippiensis) is a common, yet lesser known species of the Mississippi River drainage basin; few life history studies on the species have been published throughout its range. To describe population level gonad development, seasonal abundance, and age and growth, yellow bass were collected every 7-14 days with monofilament gill nets from 14 November 2008 to 17 November 2009 from the upper Barataria Estuary (UBE) in south Louisiana. Mean catch-per-unit effort (CPUE) was highest from February-April, indicating that yellow bass used the UBE seasonally. Yellow bass abundance peaked as temperatures reached 18-22 C. Total length, weight, and gonadosomatic index (GSI) were measured from each whole fish collected (n = 1043). Age was estimated using sagittal otoliths and annulus formation was confirmed by marginal increment analysis. Although yellow bass ranged from age 1 to age 4, the population was dominated (95%) by age 2 fish.

Characterizing the habitat of large, navigable rivers is difficult, yet this information is critically important to the conservation of a variety of resident aquatic species. We used low-cost sonar habitat mapping to map benthic substrates throughout nearly 1000 km of four Coastal Plain rivers in Georgia and to quantify the distribution of rocky substrates that may serve as potential spawning habitat for two imperiled sturgeon species, the shortnose sturgeon (Acipenser brevirostrum) and the Atlantic sturgeon (Acipenser oxyrinchus). Although we identified hard, rocky substrates in roughly half of the river km suggested by previous researchers as potential spawning zones, mapping revealed hard substrates in many other locations as well.

North Carolina Wildlife Resources Commission (NCWRC) manages approximately 6400 km of self-sustaining, wild trout streams, and recent trout angler opinion data indicated that most trout anglers fish these waters. Given the popularity of wild trout angling, increasing understanding of angler use of these resources would benefit NCWRC. However, gathering this information can be labor intensive and costly, and as a result, very little is known about angler usage of wild trout resources in North Carolina. Recent advances in digital camera and motion detection technology provide a potential low-cost alternative to typical manned-creel surveys. In an effort to obtain angler use information for wild trout resources in North Carolina, trail cameras were stationed along two wild trout streams with only one or two access points.

Diverse groups of anglers fish the variety of trout waters managed by the North Carolina Wildlife Resources Commission (NCWRC), and in 2008 these trout anglers contributed approximately US$174 million to North Carolina's economy. Given the importance of these coldwater resources and their popularity with anglers, the NCWRC initiated a management planning process in 2010 that relied upon collaboration with trout anglers and resource management partners to revise its original Trout Management Plan adopted in 1989. Input meetings were held with staff representing multiple NCWRC divisions and other state, federal, and non-governmental resource management partners to review coldwater management topics. Five focus groups were held May-June 2010 prior to the revision of the Trout Management Plan to identify and discuss key issues and concerns related to North Carolina trout management and obtain detailed information about trout angler opinions.

We explored whether increased river flows negatively affected growth of largemouth bass (Micropterus salmoides) in the lower Ouachita River, Arkansas. To test this hypothesis, largemouth bass (n = 460) were collected during 2008-2010 from the Felsenthal Reservoir region of the river. Largemouth bass were aged and annual growth increments were calculated using standard back-calculation techniques. Growth of largemouth bass was relatively rapid in the Ouachita River, with von Bertalanffy growth model parameters determined as L_∞ = 513 mm, K = 0.324, and t_ο = -0.314; catch-curve analysis estimated that total annual mortality of the population averaged 48% (95% CL 42%-54%). Back-calculated growth increments of largemouth bass were compared across years classified as "high-flow," "low-flow," and "average-flow" based on analysis of historical June-October hydrology (i.e., corresponding with the largemouth bass growing season).

Lake Monticello in southeastern Arkansas is a renowned destination for trophy-sized (≥3.63 kg) largemouth bass (Micropterus salmoides; LMB). However, little analysis has been conducted on population characteristics of this population and the anglers fishing for them. Therefore, the size structure and potential harvest of the bass population was evaluated in the context of an existing 406-533 mm slot-length limit (SLL) and other potential SLLs. A total of 1023 LMB was collected using electrofishing during springs 2006-2007. Differences in growth were detected among gender with only one male aged above the slot. Modeling results suggested that alternative SLLs (457-559 mm or 483-559 mm) marginally increased the number of harvestable fish and number reaching trophy size while reducing the number dying within the slot. A 12-mo creel survey (n = 820 parties) revealed that 72% of anglers targeted bass, with most bass harvested (76%) below the slot.

The effects of fish-hook type on hooking location and post-release mortality of recreationally and commercially targeted fish species have been well studied. We examined how fisheries management agencies along the coastal United States had incorporated fish-hook data into fisheries regulations and how visible and accessible those regulations were to anglers. We reviewed state recreational hook regulations on natural resource agency websites of 23 states. To assess the accessibility of hook regulations to anglers, we conducted an online survey that was distributed by email to participants throughout the United States including fishing enthusiasts, fishing clubs, conservation organizations, state agency officials, and students and faculty in resources departments at multiple universities. Survey participants ranged from non-anglers to experienced recreational anglers.

We described and compared population dynamics of introduced flathead catfish (Pylodictis olivaris) between the Satilla River, Georgia, and the Little Pee Dee River, South Carolina. Both of these Atlantic coastal plain rivers are blackwater, low productivity systems that historically supported popular redbreast sunfish (Lepomis auritus) fisheries. Flathead catfish have been established in the Little Pee Dee River since the late 1970s or early 1980s, whereas the species was introduced into the Satilla River in the mid 1990s. Both populations are managed differently by their respective state fisheries agencies with an intensive annual flathead catfish removal program on the Satilla River beginning in 1996 and a more recent, less intensive removal program on the Little Pee Dee River that began in 2011.
