Stopover Habitat and Its Importance in the Conservation of Landbird Migrants Conservation of neotropical landbird migrants will be compromised if attention is not focused on habitat requirements during migration. Habitat use during migration has profound consequences for a bird's (1) ability to satisfy energetic requirements, (2) vulnerability to predators, and (3) exposure to environmental stress. Largely correlative evidence indicates that landbird migrants select among available habitats on the basis of factors intrinsic to the habitat, such as food availability, habitat structure, and cover in relation to predation risk.

Mississippi Alluvial Valley Forest Conversion: Implications for Eastern North American Avifauna Because bottomland forests of the lower Mississippi Alluvial Valley (MAV) are valuable as breeding, wintering, and en-route habitat during migration, we investigated the impact of changing land uses in the MAV on avian abundance and diversity at the local and continental scales. Checklist inventories from 5 studies conducted in the MAV during 1985-1992 confirmed that bird species that occur in the MAV represent a substantial proportion of the entire avifauna of eastern North America (ENA).

Density-dependent Fishing Mortality of American Shad in the Altamaha River, Georgia Catchability of American shad (Alosa sapidissima) from the Altamaha River, Georgia, was compared with population size of female adult spawners to determine if density-dependent fishing mortality was occurring in that fishery. Mark-recapture techniques and effort and harvest data were utilized to examine this relationship. An inverse power function described the relationship between fishing mortality per unit effort and female population size from 1982 to 1991. The relationship became slightly stronger by holding the flow variable constant.

Cultured shortnose sturgeon juveniles, age 11-330 days, were exposed to different salinity (0-35 ppt) and dissolved oxygen concentrations (2.0-5.0 mg/liter) in a series of experiments designed to examine tolerance levels. Tolerance to increased salinity improved with age. Fish 76 days old experienced 100% mortality in a 96-hour test when exposed to salinities ≥15 ppt while 330-day-old fish tolerated salinities as high as 20 ppt for a duration of 18 hours but exhibited 100% mortality at 30 ppt. Younger fish were also more susceptible to low oxygen concentrations than older fish. Wallace E. Jenkins, T. I. J. Smith, L. D. Heyward

Characteristics of the Adult Segment of the Savannah River Population of Shortnose Sturgeon During 1984-1992, 626 adult shortnose sturgeon (3.5 male:l female) were captured in the Savannah River. Significantly more fish were captured in the lower (rkm 42-75) than the upper (rkm 160-299) river. Radio telemetry data indicated that spawning appeared to occur upriver, between rkm 179 and rkm 278, and that the specific location and time of spawning varied annually. Some individuals spawned in consecutive years, but others apparently did not. Nonspawning fish appeared to remain in the vicinity of the fresh/brackish water interface (ca. rkm 30-40) throughout the spawning season. Mark R. Collins, T. I. J. Smith

Assessment of Striped Bass Spawning Stock in Roanoke River, North Carolina A total of 4,920 striped bass (Morone saxatilis) were collected from Roanoke River near Weldon, North Carolina, by electrofishing during the spring of 1991 and 1992. Study objectives were to determine sex ratio and age composition of the Albemarle Sound/Roanoke River striped bass spawning stock. Differences in catch per unit effort (CPUE) between years, among year classes, and between sexes were analyzed. Male striped bass represented 83% and 87% of the sample over the 2 years. Nearly all male (99%) and female (91%) striped bass captured were Ages 2 through 4. Kent L. Nelson, J. W. Kornegay

Louisiana's Brown Shrimp Monitoring and Management Program The Louisiana Department of Wildlife and Fisheries has conducted long term monitoring for shrimp since the mid 1960's. For the purpose of monitoring shrimp populations, the State was divided into 7 Coastal Study Areas. Each of these Areas represented a distinct hydrological basin within the coastal zone. Data collected from sampling locations within each of these Study Areas was used to set shrimp seasons on a statewide basis. Data collected during the early years of the monitoring program indicated that the State's shrimp resources could be divided into 3 distinct management zones. William S. Perret, P. E. Bowman, L. B.

Impacts of a Threadfin Shad Winterkill on Black Crappie in a North Carolina Reservoir A total winterkill of threadfin shad (Dorosoma petenense) in B. Everett Jordan Lake, North Carolina, facilitated assessment of their role in the growth and condition of black crappie (Pomoxis nigromaculatus). Reductions in size at age and Wr were observed in Age 3 and older crappie in the year of the winterkill. Reestablishment of threadfin shad in the following year led to improvements in crappie population parameters, and within 2 years of the shad winterkill, crappie growth and condition had returned to pre-kill levels. The presence of a strong gizzard shad (D.

We used larval drift nets to assess reproductive output of channel catfish (lctalurus punctatus) in order to determine stocking needs in the Kings, Mulberry, Illinois, and Buffalo rivers in Arkansas. In each river, drift nets were deployed at the head of riffles and fished on random dates from 15 June to 22 July 1991 to determine relative abundance of young-of-year (YOY) catfish. Abundance of YOY catfish, an index of reproductive output, varied significantly among rivers, although all rivers are similar in geomorphology and located in the same physiographic region of the state.

A standardized stream monitoring program conducted on the Altamaha River, Georgia, from 1988 to 1992 was successful in detecting substantial changes in sport fish populations. Flathead catfish (Pylodictus olivaris) electrofishing catch rates generally increased from 1988 to 1992 reaching a peak CPUE of 90 fish per hour in 1990. CPUE of flathead catfish was significantly different (P < 0.05) between years and sites. Percent composition of flathead catfish in ictalurid samples doubled over the 5-year study period.

Linear Ranges of Large Flathead Catfish in Two Mississippi Streams Radio telemetry and mark-recapture techniques were used to monitor linear ranges of large (TL > 510 mm) flathead catfish {Pylodictis olivaris) in the Big Black River and the Tallahatchie River, Mississippi. Linear ranges of transmitter-tagged fish averaged 0.75 km (SE = 0.09 km, N = 6) in the Big Black River and 1.04 km (SE = 0.13 km, N = 8) in the Tallahatchie River. In the Big Black River, 116 adult flathead catfish were tagged with Floy T-Bar anchor tags. There were 6 recaptures from the Big Black River with all recaptures occurring <2 km from release sites.

Angler Diary Survey of Flathead Catfish in the Yadkin-Pee Dee River System, North Carolina An angler diary survey of the flathead catfish {Pylodictis olivaris) sport fishery in the Yadkin-Pee Dee River system, North Carolina, was conducted (1989-1991) to examine the current fishery and provide a baseline for future comparisons. The objective of the study was to describe the quality of the fishery in terms of fish caught per hour (CPUE), size distribution, and condition (K) of the catch. Forty-four volunteer anglers were recruited to keep records of their fishing trips. Twenty cooperators reported 348 trips.

Creel survey and cove rotenone data from 17 reservoirs in Piedmont North and South Carolina were subjected to correlation and regression analysis to examine environmental factors influencing fish production and taxonomic composition and to develop models for the prediction of total harvest and biomass. Summer surface chlorophyll concentration was the best univariate predictor of total harvest (r2 = 0.93) and one of the best predictors of total biomass (r2 = 0.79). Mary S. Rodriguez, L. L. Olmstead

Assessment of the North Carolina Wildlife Resources Commission Environmental Permit Review Program The North Carolina Wildlife Resources Commission (NCWRC) Environmental Permit Review Program was evaluated. The objective was to classify and compare a sample of environmental permit reviews conducted in 1989 with permit disposition. A secondary objective was to assess the degree of incorporation of conditions attached to permits recommended by NCWRC personnel for approval with modification. One hundred and ten permit applications were reviewed. State and federal regulatory agencies, with few exceptions, denied fewer permit applications than were recommended for denial by the NCWRC.

Evaluation of Control Techniques for Avian Predators of Pond-reared Fishes Research and development studies involving red drum and hybrid striped bass culture in coastal ponds have been seriously impacted by avian predators, especially when overwintering was required. Studies were conducted at the Waddell Mariculture Center to document the effect of predation by birds and also to test various non-lethal control techniques. Use of pyrotechnics, flash tape, "evil-eye" balloons, aerial balloons, and various wire grid patterns over a pond offered only short term protection. May L. Baird, T. I. J. Smith, W. E. Jenkins

Gill Net Sample Size Requirements for Temperate Basses, Shads, and Catfishes I estimated variance-mean (s2-x ) relationships for gill net catches of 8 forage and sportfish species plus a composite group composed of all species combined. These relationships explained 75%-95% of the variation in loge(s2). Predictive equations for loge(s2) were back-transformed to a linear scale, adjusted to correct for transformation bias, and substituted into a standard equation for estimating sample size requirements as a function of the desired level of precision and expected sample mean.

Size Selection of Prey by Young Largemouth Bass Size selective predation has been documented in many species of fish. The majority of these studies have focused on the feeding behavior of adults. I examined the size selection predation of largemouth bass Micropterus salmoides ≤200 mm total length (TL), with particular emphasis on shift size bass. Shift size bass (approximately 100 mm TL) were those fish just changing from invertebrate prey to piscivory. Shift size bass were size selective and consumed prey 35% their own TL. As they grew larger, they consumed proportionately smaller sized prey.

Relationship Between Power Plant Recharge Waters and Young-of-year Largemouth Bass Abundance This study evaluated the relation between young-of-year (YOY) largemouth bass (Micropterus salmoides) density (TV/ha) and monthly rainfall, make-up water, and discharge of a 547-ha power plant cooling reservoir in Bexar County, Texas, for 1983-1992. Young-of-year largemouth bass density and total dilution (rainfall, makeup water, and discharge combined) during January-February were significantly related (r2 = 0.68, P < 0.05).

Differences in Estimates Generated by Two Tag Types During 1978-1991, Floy FD-68B "T bar" type tags and Floy internal anchor tags were used on Lake Walter F. George to estimate exploitation of the largemouth bass population. Tag loss and non-reporting of tags by anglers were calculated in an attempt to adjust exploitation and total catch estimates. Over the 5-year period, tag loss averaged 20% per year for Floy FD-68B tag and <1% for the Floy internal anchor tag. Non-reporting of tags by anglers was estimated to be 33%.

Percent year class contribution was evaluated for genetically-marked Florida largemouth bass (Micropterus salmoides floridanus) x northern largemouth bass (A/. 5. salmoides) stocked in 3 Texas reservoirs. Electrofishing catch rate and size structure data were used to determine population characteristics of each study reservoir. Stocking rates of genetically-marked fingerlings ranged from 30 to 200 fish/ha. Post-stocking collections were made by electrofishing at permanent stations over a 4-year period. David R. Terre, S. J.

Distribution and Habitat Selection of Florida and Northern Largemouth Bass in Lake Tawakoni, Texas An ultrasonic-telemetry study was conducted to compare spatial and temporal distribution and habitat use of Florida largemouth bass (Micropterus salmoides floridanus, FLMB) and northern largemouth bass (M. s. salmoides, NLMB). Twentyfour largemouth bass (12 FLMB and 12 NLMB) were implanted with ultrasonic transmitters and released in Waco Bay, a 1,215-ha major arm of Lake Tawakoni, Texas. Eleven FLMB and 10 NLMB were located at least once during the year-long study period (range 1-24).

First Year Assessment of Delayed Harvest Trout Regulations North Carolina implemented delayed harvest regulations in 1992 to diversify trout angling opportunities. Delayed harvest regulations allowed only catch-and-release fishing of stocked catchable-sized trout from 1 March-5 June 1992. Creel surveys were conducted on 2 streams to assess differences in angler trip characteristics, particularly catch rates, between delayed harvest and regular put-and-take (hatchery supported) trout streams.

A roving creel survey was conducted on Lake Hartwell, Georgia and South Carolina, in 1992 to evaluate spatial and temporal differences in anglers' awareness of a fish consumption advisory and their fish consumption habits. A higher percentage of Georgia residents were interviewed in areas of Lake Hartwell that included large proportions of the Georgia shoreline. The frequencies of anglers that ate fish they caught from Lake Hartwell and percentages of anglers not aware of the current health advisory were generally higher in these areas.

Evaluation of an Entanglement Gear Fishery in an East Texas Mainstream Reservoir A creel survey was conducted from 1 September 1990 through 31 August 1991 to estimate fishing pressure and catch rates, initial mortality, and value of fishes captured in an entanglement gear fishery at Wright Patman Reservoir, Texas. Mean daily net fishing pressure ranged from 3,508 m/day (fall) to 763 m/day (summer). Commercial nets accounted for 85% of the annual netting pressure. Catch rates of sport and commercial fishes declined as bar mesh size increased from 76 to 102 mm. Michael J. Ryan, F. W. Janssen

A volunteer angler diary program was evaluated as a data source compared to traditional fisheries census techniques (i.e., electrofishing, gill netting, and on site creel surveys). Anglers were supplied fishing diaries and asked to record lengths of fishes caught, location, and time fished in Texas public waters, 1986-1988. Volunteer angler-supplied (ANG) length and catch-per-unit-effort (CPUE) data were then compared to traditional fisheries census data for the same season and water body. John A. Prentice, B. W.

Monitoring Trophy Largemouth Bass in Oklahoma Using a Taxidermist Network A network of cooperating taxidermists provided liver samples for phenotypic determination and scale samples for age and growth analysis of trophy largemouth bass (≥3.6 kg). This network provided data not available through standardized sampling methods. Two hundred fifty-one samples were received from 34 lakes over a 6-year period. Ninety-three percent of these bass contained Florida largemouth bass alleles. Florida largemouth bass and Fl hybrids were generally longer and heavier than northern largemouth bass or Fx phenotypes.

Evaluation of a Protected Slot Regulation for Largemouth Bass on Lake Sutton, North Carolina A 305-406 mm protective slot and 4 fish daily creel limit, allowing harvest of 2 fish <305 mm, was placed on largemouth bass (Micropterus salmoides) in Lake Sutton during July 1989. The purpose of the regulation was to protect slot length bass and increase the angler catch rate for bass >400 mm. The objective of this investigation was to evaluate the regulation's effectiveness by comparing size distributions, PSD and RSD40 of fish captured by electrofishing and anglers, as well as angler catch rates of bass >400 mm, before and after the regulation change.

Effects of Minimum Length Limits on Smallmouth Bass in Meredith Reservoir, Texas The minimum length limit for smallmouth bass Micropterus dolomieu in Meredith Reservoir, Texas, was increased from 254- to 305-mm TL in 1986 and to 356 mm TL in 1988. Population assessments indicated these limits contributed to an abundance of 178- to 280-mm bass which displayed low condition indices and slow growth. Angler catch rates of smallmouth bass increased but harvest rates and yield decreased following implementation of length limits. A 305- to 381-mm slot length limit was recommended to improve population structure and increase growth, condition, and harvest.

Evaluation of a Trophy Bass Length Limit on Lake Fuqua, Oklahoma Changes in largemouth bass (Micropterus salmoides) and forage populations were analyzed in Lake Fuqua, Oklahoma, following its designation as a Trophy Bass Lake. A 356-558 mm slot limit for bass was established in 1990 after anglers reported catching many large bass, including a state record. The electrofishing catch-per-hour (C/f) of bass >355 mm in 1993 (C/f = 24) was significantly higher than in 1989 (C/f = 7). The abundance of bass >508 mm also increased significantly from 1989 (C/f = 1.4) to 1993 (C/f = 5.0). The electrofishing C/f of trophy bass (>558 mm) did not change.

Managing a Controversial Goose Hunt on a Suburban Reservoir A 1993 hunt for Canada geese (Branta canadensis) on 15,390-ha Lake Sidney Lanier, near Atlanta, was the most controversial hunting event to date in Georgia. The hunt was proposed principally as an effort to reduce nuisance problems from a goose flock numbering 1,500-2,000 birds. Media and public attention was intense for several months preceding the hunt with at least 29 articles published in both local and statewide newspapers. Media attention peaked on the first day of the hunt with 4 television stations, 2 newspapers, and 1 radio station covering the hunt on site. Lawrence E. McSwain, K. E. Kammermeyer, D. Cochran

Ninja Crawlers—Special Investigation of the Interstate and International Turtle Trade The southeastern United States is home to numerous species of endemic reptiles. The public's desire to possess reptiles, especially turtles, has increased substantially in recent years, perhaps because of the "ninja turtle craze." A new lucrative interstate and international market for the sale of "pet" turtles has developed. Loss of suitable habitats combined with commercialization have depleted populations of several species resulting in their being listed as threatened or endangered or otherwise being legally protected. Rareness of a species increases market demand.

English and American Wildlife Law: Lessons from the Past English wildlife law has been well documented for over 1,500 years. Since the Middle Ages the English have tried implementing, at one time or another, almost every law that could be imagined for the taking and harvesting of wildlife. The penalty for violations of these laws have ranged from a fine, prison, mutilation, transportation, to even death. Despite all these laws and draconian punishments, poaching still persisted. Before we propose or try to change any of our current laws, we should review the past and see if this new law or change has failed or worked earlier.

Environmental Law Enforcement in Georgia Wildlife conservation is an extremely complex matter. Not only must the different species be managed but also their habitat. Any factor that impacts the habitat is of concern to the wildlife manager. Man's activities are key factors in the destruction and loss of habitat. The bulldozing of habitat to make way for new buildings and factories creates by-products that endanger not only wildlife and their habitats but also people. These by-products are wastes and other pollutants.

Paintball Training for Wildlife Officers The utilization of paintball scenarios is a viable part of any department's ongoing advanced firearms training program. They isolate potential tactical problems, allowing the firearms instructor to concentrate his efforts in these areas during regular live fire exercises. Most importantly, paintball training gives the individual officer much needed, and henceforth unavailable feedback from a living, breathing target. Lieutenant Bill Jolly, Sergeant Gerald Barnett

Wildlife Forensics: A New Approach to Species Conservation and Preservation In 1989, the U.S. Fish and Wildlife Service established the National Fish and Wildlife Forensics Laboratory in Ashland, Oregon. The mission of the laboratory is to provide forensic support to law enforcement investigations at the federal, state, and international levels. The primary difficulty is that commonly accepted species-defining characteristics are often not present on wildlife parts and products seized by wildlife law enforcement officers and submitted to the lab as evidence.

Activities, Regulatory Preferences, and Regulatory Perceptions of Tennessee Anglers A 1992 survey of Tennessee anglers was used to determine who is fishing and how often, the species they fish for, and how anglers perceive the regulatory structure. The results are based on telephone interviews with 450 active licensed anglers. Nearly 81% of the anglers visited a Tennessee reservoir in 1992, while 41% fished warm water streams, 28% farm ponds, and 22% trout streams. Over 60% preferred separate regulations for reservoirs. Active reservoir fishermen were more likely to support individual regulations. Paul M. Jakus, J. M. Fly, J. L. Wilson

Natural Design in Development: Promoting a Team Approach to Environmentally Sound Development Design In Maryland, human populations are increasing and are accompanied by increasing land development. In response, state and local governments have enacted environmental laws and regulations to limit impacts on wetlands, forests, and the Chesapeake Bay. Communication among development, land planning, and natural resource professionals during the development design process could enhance regulation by helping to insure designs meet requirements and consider impacts of development on wildlife habitats not protected by law. This communication seldom occurs.

Evaluation of an Outdoor Facility for Maintaining Wild Raccoons Up to 10 raccoons (Procyon lotor) were live-trapped and held within covered wire cages for about 1 month each season during June 1988-August 1989. Animals were fed 250-300 g of dry dog food daily and provided water ad libitum; percent change in body mass during captivity was used to evaluate the response of raccoons to the holding facility and maintenance protocol. Change in body mass at release varied from - 0.6 kg to 1.6 kg. Daily percent change averaged 2.7%; the largest total percent change in body mass of 70%.

Waterfowl and American Coot Habitat Associations with Mississippi Catfish Ponds Approximately 41,375 ha of catfish ponds in Mississippi attracted as many as 150,000 waterfowl and American coots (Fulica americana) during winters in the mid-1980s. We evaluated relationships between numbers of northern shoveler {Anas clypeata), ruddy duck (Oxyura jamaicensis), scaup (Aythya affinis, A. marila), and American coot and habitat features of catfish farms in west-central Mississippi during winters 1983-1986. All species tended to use large clusters of ponds with other ponds nearby. High waterfowl use also occurred on pond clusters near the Mississippi River. James A. Dubovsky, R. M. Kaminski

Energy Utilization of Natural Prey Items by Southeastern Bobcats Energy utilization of natural prey items by Mississippi bobcats (Felis rufus) was measured and annual prey requirements were estimated. Male and female bobcats were fed 5 diets of natural prey items, December 1990-February 1991. There were significant differences in amount of energy (kcal) in prey items, with white-tailed deer (Odocoileus virginianus) meat (5.7295) greater (P < 0.05) than fox squirrel (Sciurus niger) (5.0304).

Immobilization of Captive White-tailed Deer with Mixtures of Telazol and Rompun We evaluated mixtures of Telazol and Rompun for immobilizing captive white-tailed deer (Odocoileus virginianus). Three doses of Telazol and Rompun were used to immobilize adult male deer (N = 32), and 5 doses were used to immobilize yearling deer (N = 78). Mixtures of these agents immobilized deer quicker and with deeper sedation than previously experienced using Rompun alone. There were no differences in immobilization or recovery periods between doses of 250:150 mg versus 167:200 mg Telazol:Rompun in adult males. Stephen R. Schultz, M. K. Johnson, W. A. Forbes

Wild Turkey Use of Control-burned Loblolly Pine Plantations Pine (Pinus spp.) plantations comprise a major habitat type in the Southeast, and burning is used for forest and wild turkey (Meleagris gallopavo) management. We studied turkey hen (N = 165) use of control-burned loblolly pine (P. taeda) plantations, July 1986-March 1991, in Kemper County, Mississippi. Generally, hen use of plantations during summer (Jul-Sep), fall (Oct—Dec), and winter (Jan-Mar) was equal to or less than available for plantations <1 year and 5:7 years since-burned. Use was equal to or greater than available for plantations 1-6 years since-burned. John E. StysG. A. Hurst, B. D. Leopold, M. A. Melchiors

Food Preferences of Spring-migrating Blue-winged Teal in Southwestern Louisiana We studied effects of pair status, molt intensity, and year on food selection by migrating male blue-winged teal (Anas discors) in southwestern Louisiana during springs 1990 and 1991. Diets consisted primarily of animal foods; but plant material, consisting mostly of seeds, comprised as much as 44%. There was no difference in animal food consumption by paired and unpaired males; however, the proportion of animal material in the male diet was greater in 1990 than in 1991. Animal food consumption was not positively correlated with mean molt intensity. Scott W. Manley, W. L. Hohman, J. L. Moore, D. Richard

Food Habits of Native Wild and Farm-released Juvenile Alligators Stomach contents of 108 juvenile alligators (Alligator mississippiensis) were analyzed to determine if alligators hatched and raised in captivity (until 120-cm size) then released to the wild would be capable of foraging successfully for food. Seventyeight farm-reared, post-released alligators harvested during the 1991 annual alligator hunt on Marsh Island Wildlife Refuge and 30 native wild alligators harvested of similar size class were selected and stomach contents compared.

Evaluation of Two Lures for Furbearer Scent-station Surveys Two odor attractants, Carman's Distant Canine Call (CDCC) and W-U lure, were monitored simultaneously at scent-station transects in 5 units of the Big Thicket National Preserve, Texas. We examined transects for furbearer tracks for 3 consecutive days quarterly from January 1987 through March 1988. Significantly (X2 = 26.9, df = 1, P < 0.01) greater numbers of furbearers were attracted to scent stations with CDCC than to those with W-U lure. We recommend CDCC over W-U lure for attracting furbearers to scent stations in Southeastern pine habitats. Reginald J. Stapper, D. L. Rakestraw, D. B. Fagre, N. J. Silvy

Heartwood Formation in Loblolly and Longleaf Pines for Red-cockaded Woodpecker Nesting Cavities Information on the relationship of heartwood development to site quality, competitive index, tree age, and tree size for loblolly (Pinus taeda L.) and longleaf (P. palustris Mill) pine is presented. Twenty-nine loblolly and 26 longleaf pine stands representing a range of age classes (30 to 170 years) and site indices (12 to 37 m) were sampled in the Southeast. At age class 50, a portion of the loblolly pine growing on site index 24 m and better sites contained sufficient heartwood (≥12.7 cm at 6.7 m) for redcockaded woodpecker (Picoides borealis) (RCW) cavity activity.
