Preliminary Assessment of an Alaska Steeppass Fishway on a North Carolina Blackwater Creek Despite the large number of low-head dams on North Carolina streams and rivers, fishways have rarely been used to restore access to habitat upstream of dams. The goal of this study was to determine the use of a prefabricated Alaska steeppass fishway installed at a low-head dam on Black Creek, a blackwater tributary of the Neuse River near Smithfield, North Carolina. Between 21 February and 2 June 2003 study period, the ladder was used by 949 gizzard shad (Dorosoma cepedianum), 2 American shad (Alosa sapidissima), and 1 golden shiner (Notemigonus crysoleucas).

Predatory Impact of Muskellunge on New River, Virginia, Smallmouth Bass Stomachs of 171 muskellunge (Esox masquinongy) ranging in length from 358 to 1270 mm were examined to evaluate fish diet and to estimate through bioenergetics modeling the predatory impact of muskellunge on smallmouth bass (Micropterus dolomieu) in the New River, Virginia. Fifty-five percent of muskellunge stomachs examined contained food. Ninety percent of muskellunge stomachs that contained food contained fewer than six items. Travis O. Brenden, Eric M.

Population Dynamics of a Migration Limited Shortnose Sturgeon Population Upstream migration of the Cooper River, South Carolina, population of shortnose sturgeon (Acipenser brevirostrum) is severely limited at Pinopolis Dam (river km 77). Shortnose sturgeon congregating and spawning in the tailrace of the dam has been documented but data is lacking on the group's population dynamics. From 1995 through 1999, the population was sampled in the tailrace with 91.4 m long bottom-set gillnets during the spawning season when fish were concentrated in the area. Douglas W. Cooke, James P. Kirk, James V. Morrow, Jr., Steven D. Leach

Several diseases of fish present challenges to both fishery managers and aquaculturists in the Southeast. Emerging diseases along with a suite of known and persistent diseases can present management challenges for native species and biodiversity, can cause loss of recreational fishing opportunities, and can affect local economies or reduce profitability in commercial aquaculture. Emerging diseases such as mycobacteriosis in striped bass, epizootic ulcerative syndrome in menhaden, and spring viremia of carp present some new challenges to fishery managers.

Multispecies Trout Management on a Small Ozark Tailwater Beginning in September 1998, the Arkansas Game and Fish Commission (AGFC) conducted a three-year creel survey on the trout fishery below Beaver Dam, Arkansas, to collect current information on angler effort, catch, and harvest. Angler catch rates for rainbow trout (Oncorhynchus mykiss) remained high (>1.0 fish/h) throughout the study. However, a reduction in angling effort coupled with a high rate of voluntary release resulted in low exploitation of the put-and-take rainbow trout fishery. Jeffrey S. Williams, Darrell W. Bowman, C.

Microhabitat Characteristics of Nocturnal Roost Sites of American Woodcock in East Texas Long-term declines in American woodcock (Scolopax minor) populations may be partially the result of low survival rates on wintering grounds especially in nocturnal habitats. We compared microhabitat characteristics of woodcock nocturnal roost sites to random sites in eastern Texas. We located woodcock roost points by nightlighting in winters of 2000-01 (45 points) and 2001-02 (74 points). Percentage bare soil, sapling-size tree canopy cover above 0.5 m, and sapling density were greater at roost than random sites. J. R. Glenn, R. Montague Whiting Jr., Jeffrey P. Duguay

We measured total length and weight and estimated daily age of 50 young-of-year shoal bass (Micropterus cataractae) collected from a hatchery pond in southwest Georgia. Daily age was estimated using otoliths and was considered the median age of ring counts from one reader who counted rings in each otolith independently three times. This sample of young-of-year shoal bass averaged 28.55 days old, 24.04 mm in total length, and 0.13 grams in weight. Daily growth rates averaged 0.85 mm day-1. The length-weight relationship was described by the equation: weight = 0.0043e0.1399*length. James M. Long, Lisa A. Klein, Alfred C. Mauldin, II

Managers and biologists have long relied on relatively inexpensive and easily collected data from hunter-harvested deer to provide information for making harvest management decisions. We sought to better understand the influence of time lags and population segment (i.e., total adult and total herd density) on the density-physical parameter relationship. P. D. Keyser, D. C.

Urban fishing programs in Arkansas rely primarily on put-take stockings of channel catfish and rainbow trout. We evaluated hybrid striped bass as a potential addition to urban fisheries by stocking this fish at densities of 95 and 96 fish/ha in two urban fishing ponds. Angler surveys were conducted three times daily for five weeks following stocking to determine angler demographics, fishing success, and attitudes/preferences. We surveyed 320 anglers comprised primarily of local urban residents. J. Wesley Neal, Sanatan Shreay, N. Elizabeth Heitman, Mark C. Leao, Kelly R. Winningham, Regina E. Edziyie, Clifton Jackson

Hatching Success of American Alligator Eggs When Subjected to Simulated Collection Trauma Hatching success of crocodilian eggs can be influenced by the age of the embryo at time of collection. We conducted an experiment to determine the amount of care necessary during egg collection to optimize embryo survival when alligators eggs at different stages of development were subjected to simulated field conditions of choppy vs. smooth water and cushioned vs. non-cushioned support. We also compared hatching success of rolled vs. non-rolled eggs at different stages of development. Jodi L. Bock, Allan R. Woodward, Stephen B. Linda, H. Franklin Percival, Dwayne A. Carbonneau

Factors Affecting Wild Turkey Recruitment in Western Virginia Annual recruitment of eastern wild turkeys (Meleagris gallopavo silvestris) should be closely monitored to regulate fall turkey seasons and reduce risk of over-harvest. However, previous studies have not encompassed the spatial or temporal scales needed to produce models that can consistently predict recruitment over a large region. Our objective was to assess the ability of using long-term data sets of sex-age ratios, oak (Quercus spp.) mast, and weather variables to forecast annual wild turkey recruitment in western Virginia.

Evaluation of Catch Card Reporting at Mississippi State Lakes We evaluated voluntarily completed catch cards as an alternative to access point surveys at intensively managed state-owned fishing lakes in Mississippi. Catch cards, with signs encouraging participation and completion, were conspicuously available to anglers. Five percent of anglers voluntarily completed catch cards; response rate increased to 13% when agency personnel verbally requested participation in the catch card program from those anglers they encountered on-site.

Evaluation of a Crappie Length Limit on Lake Chicot, Arkansas Population characteristics for black Pomoxis nigromaculatus and white crappies P. annularis combined were simulated using a dynamic pool model to determine if the current 254-mm length limit is practical at Lake Chicot, Arkansas. Catch curve regressions were used to estimate annual mortalities, and exploitation was estimated with two consecutive tag reward studies. Exploitation was adjusted for tag loss, tagging mortality, and non-reporting. Average annual mortality was 78% and adjusted exploitation was 17%. James M. Carlson, Christopher L. Racey, Steve E.

Effect of Prescribed Burning of Clearcuts on Ruffed Grouse Brood Habitat We evaluated short-term effects of prescribed burning of clearcuts on potential ruffed grouse (Bonasa umbellus) brood habitat in oak-hickory forests in western Virginia. We divided six <1-year-old clearcuts into two portions and designated one portion for prescribed burning during late fall or winter. Because of dry conditions, only four treatment areas were burned. We monitored habitat conditions on burned and unburned portions of clearcuts during the growing season preceding treatment and during the two subsequent growing seasons. Darroch M. Whitaker, Dean F.

Economic Impacts of Onshore Fishing Sites and Fishing Tournaments on the Mississippi Gulf Coast Our study attached a monetary value to marine resources associated with fishing on the Mississippi Gulf Coast. In 2001, we conducted on-site surveys (N = 475) to collect expenditures of marine onshore anglers and marine fishing tournament participants in the Mississippi Gulf Coast three-county region. We then determined the extent and economic impacts of these activities and integrated marine onshore angler economic impacts and attendances into a Geographic Information System (GIS) for the Mississippi Gulf Coast. Our survey response rate was 86%. Emily K. Loden, Stephen C. Grado, Jeanne C. Jones, David L. Evans

Distribution of Freshwater Bivalves in the Canoochee River Drainage, Georgia The Canoochee River originates in the Southern Coastal Plain of Georgia and flows through the Coastal Flatwoods to terminate at the Ogeechee River. The Canoochee Drainage is the largest tributary of the Ogeechee River and is a fifth-order woodland stream. Investigators surveyed 83 sites for freshwater bivalve presence, noting species and counting individuals. We analyzed water chemistry parameters including nitrate nitrogen, total inorganic nitrogen, total dissolved phosphate, and total dissolved copper. Kathryn E. Sukkestad, Thomas D. Bryce, Eugene P.

Cages as tools for in situ bioassays have a proven track record in monitoring the effects of effluent and sediment toxicity. Application to biomonitoring, however, has received comparably little attention. With the increasing threat of harmful algal blooms to both humans and aquatic organisms, their use as sentinels for early warning and for the examination of organism response in situ is evident.

Avian Vacuolar Myelinopathy: Unraveling the Mystery Avian vacuolar myelinopathy (AVM), a disease of unknown etiology, was first diagnosed in 1994 (Thomas et al. 1998) as the cause of morbidity and death of American coots (Fulica americana) and bald eagles (Haliaeetus leucocephalus) in the southeastern United States. The disease, now confirmed on 10 lakes in four southeastern states, also has been found in mallards (Anas platyrhynchos), ring-necked ducks (Aythya collaris), bufflehead (Bucephala albeola),one great horned owl (Bubo virginianus), and a killdeer (Charadrius vociferous).

An Evaluation of Sampling Methods for White-winged Dove Surveys in Urban Areas Texas Parks and Wildlife Department (TPWD) has used auditory call counts annually since 1949 to monitor white-winged dove (Zenaida asiatica) populations in the Lower Rio Grande Valley of Texas. Recently, white-winged doves have been expanding their distribution, and now the largest populations occur in urban areas north of their historic south Texas range. It has become necessary to develop an urban survey method to better monitor these populations. We compared two call count sampling methods for surveying white-winged doves in urban environments (i.e., transects vs. Jeff B. Breeden, Fidel Hernandez, Nova J. Silvy, Ralph L. Bingham, Gary L.

Catfishes are among the most frequently sought freshwater fishes in the United States. Yet despite the popularity of catfish angling, few angler surveys have been conducted to describe the demographics, social characteristics, and opinions of catfish anglers to assist in improving fisheries management in Missouri. Thus, the Missouri Department of Conservation conducted a statewide survey of licensed anglers in Missouri in 2002. The survey asked questions specifically related to angler demographics, species preferences, angling behavior, and angler opinions on catfish management. Ronald A. Reitz, Vincent H. Travnichek

The blue catfish Ictalurus furcatus fishery at Lake Texoma has been increasing in popularity. Guides that typically seek striped bass Morone saxatilis switch to blue catfish, particularly during the winter months when the largest individuals are most vulnerable. Low frequency electrofishing samples, collected since the early 1990s by the Oklahoma Department of Wildlife Conservation, indicate that population abundance is stable but concerns have been raised over the long term viability of the fishery in the face of increased angling pressure on the largest individuals.

Ecological Changes Following an Alewife Introduction in an Oligotrophic Reservoir: A Case History Alewife (Alosa pseudoharengus) was introduced into oligotrophic Mayo Reservoir, North Carolina, during 1992 or 1993. The species established a self-sustaining population and increased from <1% of total fish biomass in 1993 to 31% in 2000. Size-selective planktivory by the species, a well-documented phenomenon in other alewife introductions, was implicated in observed changes in the reservoir zooplankton community. J.

Roving-clerk creel surveys were conducted at Cat Island, Mississippi, during two three-year periods: 1977-1979 and 1997-1999. Angler interviews provided data of species caught with estimated weight and number, as well as duration of fishing activity. Periodic aerial counts of fishermen provided further estimates of total fishing activity. Fishing pressure increased significantly (P ? 0.05) during the 20-year study interval in numbers of fishermen and total hours fished. Wendell J. Lorio, Michael G. Pursley

2002 Alabama Freshwater Anglers Survey We conducted a mail survey to evaluate the demographics, attitudes, and practices of Alabama licensed freshwater anglers. The survey consisted of 36 questions that largely paralleled the most recent (1987) previous angler survey conducted by Alabama Department of Conservation and Natural Resources. Of the 2000 surveys mailed to randomly-selected licensed anglers, 31% (628) were returned before the stated deadline. Responses were similar to those in the last statewide survey. Tournament anglers represented only about 5% of respondents. Russell A. Wright, Dennis R. DeVries, Stan Cook, Nick Nichols

Age, Growth, and Status of Shortnose Sturgeon in the Lower Ogeechee River, Georgia Shortnose sturgeon (Acipenser brevirostrum) were monitored as part of continuing studies in the Ogeechee and Canoochee rivers adjacent to Fort Stewart, Georgia, during 1999 and 2000. Over 13,000 net-meter h soak time and 1,700 person h of effort were expended; short (27.5-m) experimental gill nets were a satisfactory sampling gear. Retention of externally mounted telemetry tags was poor (mean = 80 d), and spawning habitats were not located. The population, ranging from ages 3 to 14, was estimated at 147 individuals. Joel E.

Angler Use and Stocking Evaluation of a Coastal River Fishery in Southwest Alabama Hybrid striped bass Morone saxatilis x M. chrysops, channel catfish Ictalurus punctatus, and blue catfish I. furcatus were tagged and stocked to assess the potential for recreational fishery enhancement in a coastal Alabama river. Creel and mail surveys were completed to evaluate the existing fishery and success of fish stocking. After adjusting for angler tag reporting, tag loss, and mortality, catch rates were 2%, 11%, and 17% for blue catfish, channel catfish, and hybrid striped bass, respectively.

Animal Welfare-based Modification of the Rio Grande Wild Turkey Funnel Trap The funnel trap has proven a safe (for handlers), efficient, low-manpower method of capturing Rio Grande turkeys (Meleagris gallopavo intermedia). Field biologists in Texas maintain that private ranchers accept this technique more readily than alternatives because it is passive and only requires one person. The impact of the technique on animal welfare, however, has not been addressed. In 2002, in the first year of an ongoing population ecology study, we trapped 46 turkeys using a standard walk in trap, and 40 more where a tarpaulin was slipped over the trap prior to removing birds.

Bachman's Sparrow Habitat in the Lower Flint River Basin, Georgia Bachman's sparrow (Aimophila aestivalis) populations are generally declining throughout much of the Southeast, and habitat loss is suspected as the principal force driving declines. Therefore, we assessed the potential effects of current land use practices on Bachman's sparrows (BACS) within the lower Flint River Basin (LFRB). We then used a previously developed habitat model to quantify current available BACS habitat and used common landscape metrics to describe fragmentation of remaining habitat. Micah W. Perkins, L.

Biology of a Spawning Population of Cycleptus meridionalis in the Alabama River A spawning population of Cycleptus meridionalis was sampled 71 times in the generator outflow area below Millers Ferry Lock and Dam from 1995-2003. Sampling success ranged from 32 fish in 2001 to 247 fish in 2003. Sixty-seven percent of 1059 fish captured were males; 30% were females, and 3% were gender unknown. Females attained a greater total length and total weight than males. Regression slopes for standard length versus total length and total weight versus standard length were significantly different (P<0.01) between males and females. Maurice F. Mettee, Thomas E.

Bobcat Diet on an Area Managed for Northern Bobwhite We quantified bobcat (Lynx rufus) diet on a longleaf pine (Pinus palustris) dominated area managed for northern bobwhite (Colinus virginianus), hereafter quail. We sorted prey items to species when possible, but for analysis we categorized them into 1 of 5 classes: rodent, bird, deer, rabbit, and other species. Bobcat diet did not differ seasonally (X2 = 17.82, P = 0.1213). Most scats (91%) contained rodent, 14% contained bird, 9% contained deer (Odocoileus virginianus), 6% contained rabbit (Sylvilagus sp.), and 12% contained other. Ivy A. Godbois, L.

Brood-count Power Estimates of Rio Grande Turkey Production in Texas Brood counts are used frequently by state conservation agencies to estimate wild turkey (Meleagris gallopavo) recruitment. We performed power analyses for 25 years of Rio Grande Wild Turkey (M. g. intermedia; RGWT) brood-count data from five ecological regions of Texas in order to determine if these data had sufficient (1-b ?0.80) power to detect inter-annual and long-term changes in turkey production of 10%-20%, which we considered biologically meaningful. We then analyzed the data to determine trends in production. Fred E. Smeins, Markus J. Peterson, Nova J. Silvy, T. Wayne Schwertner

Children's Attitudes Towards Wildlife: A Comparison by Ethnicity and Community Size Using questionnaires, we surveyed fifth grade students in eastern Texas during spring 1998 to evaluate their knowledge of and attitudes towards wildlife. We grouped data from 1315 completed surveys by community size (urban, semi-urban, semi-rural, and rural) and ethnicity (black, Hispanic, and white). We compared knowledge and attitude scores among groups using Kruskal-Wallis tests and evaluated relationships between knowledge or activities and attitudes using Pearson's correlations.

Development of a Deer-guard Prototype for Florida Key Deer Due to increased deer/vehicle collisions involving endangered Florida Key deer (Odocoileus virginianus clavium), the Florida Department of Transportation (FDOT) planned to fence a stretch of U.S. Highway 1 that crosses Big Pine Key, Florida. Public access roads, which would allow deer to enter the fenced portion of the highway, posed public and wildlife-related hazards. Currently there are no structures (deer guards) that are effective in preventing deer from entering access roads. Jason D. Sebesta, Shane W. Whisenant, Roel R. Lopez, Nova J. Silvy

Effects of Controlled Dog Hunting on Movements of Female White-tailed Deer Understanding the responses of white-tailed deer (Odocoileus virginianus) to controlled dog hunting can aid in the effective implementation of canine-assisted population management strategies. We examined the 24-h diel movements of 13 radio-collared female deer exposed to dog hunting on the Savannah River Site (SRS) near Aiken, South Carolina, where regulated dog hunting has occurred since 1965. We compared diel home range size, rate of travel, and distance between extreme diel locations before, during, and after hunts from 14 September-14 December 2002. Gino J. D'Angelo, John C.

Effects of Feral Swine on Water Quality in a Coastal Bottomland Stream Feral swine (Sus scrofa) are abundant throughout the southern United States with a complex legal status and a reputation for negative interactions with wildlife and vegetation. The impacts of feral swine upon water quality are not extensively nor quantitatively documented in the published literature. We quantified the effects of feral swine on dissolved oxygen, fecal coliform bacteria, overall heterotrophic bacteria plate counts, and the presence of disease-causing bacteria. We sampled Mill Creek in western Louisiana in summer 2002 and spring 2003. Michael D. Kaller, William E. Kelso

Effects of Pen-raised Northern Bobwhite Introductions on Wild Bobwhites in South Texas Although restocking wild populations with pen-raised bobwhites (Colinus virginianus) is considered ineffective, it has become popular and acceptable among sportsmen to supplement hunting opportunities. Nonetheless, their impact on wild bobwhite populations remains unknown. The objectives of this study were to compare bobwhite survival, core area of use, and relative predator abundance between treatment (release of pen-raised bobwhites) and control areas. Ashton R.

Effects of Seed Weathering on Food Selection by Mourning Doves Changes in seed nutrient content during field weathering may have important effects on food selection by mourning doves (Zenaida macroura, hereafter ‘doves') and other granivorous wildlife. We documented changes in food selection by mourning doves with seed weathering, and we compared patterns of seed preference pre- and post-weathering with seed deterioration rates documented in an earlier-published study. Doves selected white proso millet over all other species among fresh seeds, but selected broadleaf signalgrass (Brachiaria platyphylla) over most others among weathered seeds. Steven E.

Effects of Thinning and Herbicide Application on Vertebrate Communities in Longleaf Pine Plantations Currently, nearly 98% of the land area once dominated by longleaf pine ecosystems has been converted to other uses. The U.S. Forest Service is replanting logged areas with longleaf pine at the Savannah River Site, New Ellenton, South Carolina, in an effort to restore these ecosystems. To ascertain the effects of various silvicultural management techniques on the vertebrate communities, we surveyed small mammal, herpetofaunal, and avian communities in six 10- to 13-year-old longleaf pine plantations subjected to various thinning and herbicide regimes.

Response of Plant and Invertebrate Communities to Pothole Blasting in a Giant Cutgrass Marsh Thousands of hectares of tidally-influenced, forested wetlands were cleared in the South Atlantic Coastal Zone and put into rice production during the eighteenth and nineteenth centuries. Many of these ricefields were abandoned in the late 1800s and were not maintained thereafter; hence, they no longer have functional dikes and provide poor habitat for waterfowl and wading birds due to colonization by dense stands of giant cutgrass (Zizaniopsis miliacea).

Seasonal Distribution and Movement of Striped Bass in Lewis Smith Reservoir, Alabama Lewis Smith Reservoir, an 8,583-ha Alabama Power Company impoundment on the Sipsey Fork of the Black Warrior River in north central Alabama, has received annual stockings of Gulf strain striped bass (STB-G) since 1983. Little is known about the distribution and seasonal movement patterns of striped bass in Lewis Smith Reservoir. During a three-year period from 1999-2001, 22 striped bass were captured, surgically implanted with ultrasonic transmitters and released back into the reservoir near their original capture site.
