Simulation of a Commercial Saltwater Trotline Fishery The commercial trotline fishery in the Laguna Madre, Texas, was simulated using fishery-independent sampling data to estimate landings of black drum (Pogonias cromis). Simulation of a commercial fishery can provide landings estimates and more precise estimates of confidence intervals. It can also provide information (i.e., by catch) not available through self-reported systems. Peng Chai, Lawrence W. McEachron, Joe H. Martin, Gary C. Matlock

Discovery of Naturally Reproducing Striped Bass in Two Maryland Impoundments Fishery surveys utilizing electrofishing and gill nets have documented natural reproduction of striped bass in 2 Maryland impoundments: Liberty and Piney Run reservoirs. Natural reproduction has occurred for 5 years, 1986 through 1990, in Liberty Reservoir; and for 3 years in Piney Run Reservoir, 1988 through 1990. It was initially thought that reproduction occurred in Liberty Reservoir because the relatively hard bottom and high dissolved oxygen levels allowed hatching of striped bass eggs that descended to the bottom.

Impacts of Thermal Stress on the Condition of Striped Bass Striped bass (Morone saxatilis) were sampled during summer and winter in the St. Johns River, Florida, to determine effects of summertime thermal stress on fish condition. Regressions of log weight on log length for winter and summer fish had significantly different slopes (P < 0.001) indicating larger fish were less robust than smaller fish in summer as compared to winter. Data were arbitrarily separated into 3 size categories (small = <331 mm TL; medium = 331-500 mm TL; large = >500 mm TL) to investigate thermal related stress by size. C. Kevin McDaniel, Lawson E. Snyder, Laurence L. Connor

Seasonal Movement and Distribution of Striped Bass in the Ohio River Twenty-four adult striped bass (66.8-84.6 cm; 4-7 years) from the McAlpine Pool of the Ohio River were fitted with internal radio transmitters and tracked from May 1989 through May 1990. Study fish were found to be very mobile, although seasonal movement patterns were predictable. Tagged striped bass utilized the tailwater and upper pool sections during the spring, summer, and fall. Little use was made of the lower McAlpine Pool sections by striped bass. Fish in the pool were most often located in water between 0 to 6 m (x = 92.1% all seasons).

Potential Caviar Fishery Impacts on Louisiana Bowfin Populations In recent years, a small scale bowfin (Amia calva) roe fishery in Louisiana has increased in both volume and value. To initiate an evaluation on the impacts of this fishery on bowfin populations, 3 study areas were selected to represent various ecosystems inhabited by bowfin. It was not possible to relate growth, size, and sexual maturity with age based on otolith samples. Length-frequency data suggested that 9-month-old fish ranged from 225-400 mm and 21-month-old bowfin may grow to 525 mm. Richard B. Davidson, Michael R. Walker, Gary A. Tilyou, Charles G. Lutz

Seasonal Hooking Mortality of Flathead Catfish and Blue Catfish This study was conducted to estimate the summer and winter hooking mortality of flathead catfish (pylodictis olivaris) caught on trotlines in the Colorado River and Kerrville Reservoir, Texas, and blue catfish (Ictalurus furcatus) caught on trotlines in Livingston Reservoir, Texas. Water temperatures averaged 12.2 and 13.3 C, respectively, during February and March flathead catfish winter experiments, and 27 C during summer experiments. Water temperatures averaged 12.5 and 24 C, respectively, during winter and summer blue catfish experiments.

Hooking Mortality of Channel Catfish Caught by Trotline We assessed trotline hooking mortality of channel catfish (lctalurus punctatus) at Lake Palestine, Texas, from June through September 1989. Our objective was to estimate trotline hooking mortality of channel catfish using 3 hook types and identify factors relating to that mortality. Fish collected by trotline were confined for 72 hours in submerged cages. We examined relations between percent mortality and hook type, water temperature, and oxygen concentration using logistic analysis. Kevin W. Storey, Richard A. Ott, Jr.

Historically, degradation of water quality from mining activity in the Monongahela River Basin adversely affected fish populations in the mainstem river. Improvement of water quality since 1971 has resulted in positive changes in fish populations. We assessed changes in the fishery by analyzing rotenone samples in relation to changes in water quality. Before 1970, pH ranged between 3.8 and 5.8 and alkalinity between 0.0 and 2.0 mg/1. After 1980, mean annual pH ranged from 7.0 to 7.3 and alkalinity ranged from 8.7 to 12.9 mg/1.

Rapid Placement and Retention of Passive Integrated Transponder (PIT) Tags in Grass Carp Passive integrated transponder (PIT) tags were placed in 15,344 triploid grass carp (Ctenopharyngodon idella) (200-280 mm total length) and length, weight, and tag-code data recorded for each fish at rates of 206 to 350 fish per hour. Only 43 fish (0.28%) died within 48 hours post-tagging. Survival of tagged (N = 122) and untagged (N = 131) groups of fish held in ponds 83 to 115 days post-tagging was >90% and near equal, except for 1 tagged and 1 untagged group where a columnaris disease outbreak occurred; survival in those groups was 68.0% and 69.1%, respectively.

Comparison of Larval vs. Fingerling Hybrid Striped Bass Stockings in Lake Sam Rayburn, Texas Success and cost effectiveness of stocking larval vs. fingerling hybrid striped bass (o Marone chrysops X o M. saxatilis) were evaluated at Lake Sam Rayburn, Texas. Stocking success was evaluated using gill net catch rates of age-2 hybrids, mean length of hybrids at age 2, and relative annual mortality of stocked individuals. Hatchery production and stocking cost of larvae and fingerlings were compared. There was no significant difference between gill net catch rates of age-2 hybrids stocked as larvae vs. fingerlings.

Impacts of Increasing Hybrid Striped Bass Stocking Rate and Frequency The impact of changing the hybrid striped bass (white bass Morone chrysops o x striped bass M. saxatilis o; WBxSB) stocking strategy on 2 Texas reservoirs was evaluated. Stocking of WBxSB in lakes Arlington and Graham was increased from 20 fingerlings (25-76 mm TL)/ha and 112 fry (6 mm TL)/ha biennially, respectively, to approximately 50 fingerlings/ha annually. Annual fall or winter gill net surveys were conducted to monitor densities of WBxSB and gizzard (Dorosoma cepedianum) and threadfin (D. petenense) shad. Spring creel surveys were conducted to evaluate angler utilization of WBxSB. John H. Moczygemba, Bruce T. Hysmith, W. Eugene Whitworth

Habitat Structure and Woody Debris in Southern Appalachian Wilderness Streams Stream habitat and large woody debris (LWD) loadings were inventoried in 2 southern Appalachian wilderness streams by the basinwide visual estimation technique. Little Santeetlah Creek, in a wilderness watershed that has never been harvested, contained 4 times as much wood and nearly twice as many habitat units (e.g., pools and riffles) as did Lost Cove Creek in a forested watershed, typical of the southern Appalachians, that was clearcut 80 years ago. Where stream widths were similar, pools and riffles in Little Santeetlah were smaller and more numerous than in Lost Cove Creek. Patricia A. Flebbe, C. Andrew Dolloff

Food Habits of Rainbow Trout in a Tennessee Tailwater Food habits of rainbow trout were studied at 3 locations for 1 year on the Center Hill Dam tailwater in central Tennessee. Staple food items consisted of isopods (Lirceus sp.) and chironomids. Seasonal food items from Center Hill Reservoir (threadfin shad and Daphnia sp.) were highly utilized and contributed nearly 60% to the total volume of food items taken. Occurrence of algae in rainbow trout stomachs was common and appeared to be related to seasonal forage base.

Nineteen adult walleyes were implanted with ultrasonic transmitters and tracked for 2 years at Meredith Reservoir, Texas, to determine specific behavioral characteristics. During the spawning period tagged walleyes established an activity pattern consisting of 3 phases: pre-staging, movement to within 5.5 km of the dam; staging, movement to within 2.2 km of the dam; and spawning on the rip-rap of the dam. Individual walleye established home range areas ranging in size from 141 to 2,517 ha. Fish were located most frequently in water ≤8 m deep within 100 m of shore. James O. Parks, Joseph E. Kraai

Gill Net Selectivity and Size Structure in White Bass I used a normal-skew model to calculate length-specific selection curves for white bass caught in gill nets in 55 Texas reservoirs. I used these selection curves to adjust 2 size-structure indices, proportional stock density (PSD), and relative stock density (RSD) for gill net mesh-size selectivity. Differences between adjusted and unadjusted values of PSD and RSD were small (0.6 and 2.0, respectively) when the unadjusted values were extreme (i.e., ≤10 or ≥91).

Effects of Stocking Regime and Harvest Regulation on Florida Largemouth Bass Stocking Success During a 2-year period, 250,000 Florida largemouth bass fingerlings were stocked among the endemic northern largemouth bass population of Tradinghouse Creek Reservoir (1985 = 185/ha, 1986 = 123/ha). We used electrophoresis to estimate proportions of Florida, northern, and Florida x northern intergrade largemouth bass within pre-stocking, stocking-year, and post-stocking year cohorts. Ages of largemouth bass were determined by examination of whole otoliths. John M. Mitchell, Kenneth K. Sellers, William D. Harvey, Loraine T. Fries

Mantrailers: Bloodhounds Used in Wildlife Law Enforcement Bloodhounds used as mantrailers canbe an invaluable instrument in wildlife law enforcement. The human body consists of approximately 60 trillion cells which are constantly dying and being sloughed off at the rate of about 50 million cells per second. These dead cells are acted on by bacteria which causes them to give off a gaseous odor. Each odor is slightly different, creating a unique, individual, human odor which may determine the fate of a wildlife law violator.

Hazardous Waste Criminal Investigations in West Virginia The author describes the development of this State's program to investigate crimes dealing with hazardous waste disposal. Particular emphasis is placed on the pitfalls and advantages of a hybrid positionas used in this state. As illustrated in the summary, it is not beyond the scope of state wildlife enforcement agencies to investigate and prosecute these crimes that do vast amounts of damage to the natural resources. In many cases, an act of hazardous waste disposal can do more damage to an ecosystem and its natural resources than an entire family or even generations of poachers.

Age, Growth, and Maturity of Channel Catfish in Two Southeast Louisiana Lakes Channel catfish (Ictalurus punctatus) were sampled in 2 southeast Louisiana lakes for 3 years to determine if these populations were stunted based on age structure, growth rate, and length at maturity. Mean total length at age II for Lake Maurepas and Lac Des Allemands catfish were 262 mm and 256 mm, respectively, which compared favorably to other commercially fished populations in other areas in the lower Mississippi drainage. Channel catfish in Lake Maurepas exhibited a reduced length and age at maturity when compared to other areas. Mark G. McElroy, T. Morrison, R. Gouguet

Post-mortem Weight Gain in Largemouth Bass Largemouth bass (Micropterus salmoides) held at lO.7 and 26.7 C in insulated fiberglass tanks were treated with rotenone and inspected daily to determine days-tosurfacing and change in body weight. Fish held at lO.7 C surfaced in 3-12 days, whereas fish held at 26.7 C surfaced within 24 hours. Fish at each temperature gained weight after death. Analysis of weight gain in fish held at 10.7 C produced no significant relationship between weight-gain and period of submergence for fish submerged 7 or more days. Barry W. Lyons, D. L. Cambell, W.

Distribution, Movement, and Habitat Preference of Saugeye in Thunderbird Reservoir, Oklahoma1 Ultrasonic transmitters were surgically implanted in a total of 30 saugeye (Stizostedion vitreum vitreum x S. canadense) in 1987 and 1988. Horizontal distribution, movement, distance from shore, depth, and habitat were determined during tracking of each fish. Saugeye were located ≤65 m from shore most frequently during all seasons except summer. Saugeye preferred open shore areas, and frequented submerged timber only during fall 1988 and winter 1989 when prey items may have been limited.

Hydroacoustic Assessment of Fish in Strom Thurmond Lake Mobile hydroacoustic surveys of 11 stations in J. Strom Thurmond (JST) Lake from February 1986 to October 1988 provided data to aid in identifying critical areas, times, and water release regimes for fish relative to proposed pumpback of water from JST Lake to Richard B. Russell (RIiIR) Lake. Mean relative biomass (volts2/m2 ) usually was significantly higher in the tailrace (0-450 m below RBR Dam) than in the tailwater (1-7 kmbelow RBR Dam), tributary, or lake areas in spring and summer; whereas in fall and winter, biomass was often lower than or did not differ from that in other areas.

Comparison of Methods for Estimating Relative Abundance of White Crappie We investigated the relation among estimates of abundance and size structure of white crappie (Pomoxis annularis) determined with electrofishing, trapnetting, and rotenone sampling in 4 Mississippi lakes in 1987-1989. We also examined the relations between angler harvest and estimates provided by each gear to determine whether estimates made by sampling could be used to index angling success. Electrofishing yielded 4 fish/man-hour in fall and 6 in spring, and trapnetting yielded 24 fish/manhour in fall and 9 in spring; rotenone sampling during summer yielded 8 fish/man-hour. L. E.

Diet Overlap Between Saugeye and Largemouth Bass in Thunderbird Reservoir, Oklahoma Walleye (Stizostedion vitreum vitreum) x sauger (S. canadense) hybrids (saugeye) and largemouth bass (Micropterus salmoides) ≥350 mm total length were sampled in 1988 and 1989 to determine food habits and diet overlap. Shad (Dorosoma spp.) were the most important prey of both largemouth bass and saugeye. Both predators were opportunistic, eating a variety of prey items. Although diet overlap was high, competition for food was not apparent and would not be likely to occur unless forage became limited. Richard A. Horton, E. R. Gilliland

Food and Growth of Age-o Hybrid Striped Bass in Ross Barnett Reservoir, Mississippi Food and growth of age-O hybrid striped bass (Morone saxatilis x M. chrysops) were examined during June-November 1988-1989 in Ross Barnett Reservoir, Mississippi. Shads (Dorosoma spp.), especially threadfin shad (D. petenense), made up about 70%-90% of the diet by weight. Other fish made up about 3%-20% of the diet and were eaten primarily by hybrids < 150 mm total length. Invertebrates constituted a small percentage of the diet, and were eaten mostly by fish <100 mm and not by those> 150 mm. By November, the length of age-O fish averaged 241 mm in 1988 and 227 mm in 1989.

The ability of shad populations to impact the density and composition of zooplankton populations has led to the suggestion that planktivorous shad may compete with young-of-year bass for plankton food resources and influence bass recruitment. We studied the feeding dynamics of concurrent year classes of threadfin shad (Dorosoma petenense) , gizzard shad (D. cepedianum) , and largemouth bass (Micropterus salmoides) in a North Carolina reservoir to determine the nature of feeding interactions among the species.

Reevaluating the Use of Acrylic Tubes for Collection of Largemouth Bass Stomach Contents Stomach contents of 434 largemouth bass (Micropterus salmoidesfloridanus) were collected with clear acrylic tubes. Sixty-four percent of the bass contained food. No significant differences (P > 0.05) in percent recovery of food items by weight occurred among 3 biologists for the 6 size groups studied. Greater than 80% recovery by weight of all food was obtained with acrylic tubes in 6 size groups of bass ranging from 100 to 590mm TL. Seven percent of bass that yielded no food when sampled with tubes actually contained food. Richard L. Cailteux, W. F. Porak, S. Crawford

Characteristics of Fox Enclosures in Florida We inspected 17 fox enclosures and interviewed 26 operators to collect information on enclosure characteristics and use in Florida. Size of enclosures (N = 26) ranged from 30 to 360 ha (¯x = 108 ha). Red fox (Vulpes vulpes), gray fox (Urocyon cinereoargenteus), and coyote (Canis latrans) stocks were obtained from states in the southeast and midwest. Operators (54%) preferred coyotes exclusively or in combination with foxes: coyotes were admitted to be present in ≥35% of enclosures visited. Owners reported enclosure costs to be $40/ha. Mark A.

Influence of Acorn Use on Nutritional Status and Reproduction of Deer in the Southern Appalachians We examined the influence of acorn abundance on fall and winter diets and on nutritional and reproductive status of white-tailed deer (Odocoileus virginianus) in the Southern Appalachians from 1983 to 1988. When acorns were abundant, they dominated the diet; when they were scarce, leaves of broadleaf evergreen species, primarily rosebay rhododendron (Rhododendron maximum), largely replaced acorns in the diet. When acorn production was poor, kidney fat indices in winter were significantly lower for most sex and age classes. James M. Wentworth, A. S. Johnson, P. E. Hale

Wild Turkey Use of Loblolly Pine Plantations for Nesting and Brood Rearing Wild turkey (Meleagris gallopavo) hens were monitored by telemetry from January 1987 through August 1988 in Kemper County, Mississippi. Thirty-nine of 52 hens reached incubation. Nesting success was 46% in 1987 and 36% in 1988. In 1987, all 12 located nests were in loblolly pine (Pinus taeda) plantations. Eleven hens nested in 17- to 19-year-old plantations; I hen nested in a 9-year-old plantation. In 1988,21 located nests were in plantations and I hen was in a mature pine-hardwood forest. Most hens (81 %) nested in plantations age 13-20 years old. John D. Burk, R. R. Smith, G. A. Hurst, B. D. Leopold, M. A. Melchiors

Survival and Nesting Success of Late Winter Wild Turkey Introductions During late winter 1988 and 1989, 18 radio-marked eastern wild turkey (Meleagris gallopavo sylvestris) hens released into Natchez Trace State Park, Forest and Wildlife Management Area (Natchez Trace), and 20 radio-marked Natchez Trace (resident) hens released at the capture site were monitored continuously throughout the nesting and brooding season. Introduced turkeys experienced greater mortality than residents, especially during the 30-day period following release (P <0.05). Introduced birds displayed more frequent and greater daily movements than resident hens. Joseph H. McGuiness, J. M. Benner, W. P. Smith

Waterbird Use of Open Marsh Water Management Ponds in Maryland During autumn 1985, we investigated waterbird use of Open Marsh Water Management (OMWM) ponds and use of natural ponds in an adjacent impoundment in Maryland. Dabbling ducks used ponds with dense widgeongrass (Ruppia maritima) more than ponds with sparse or no widgeongrass (P <0.01). Wading birds and shorebirds used the natural ponds more than the OMWM ponds (P <0.01), mainly because the OMWM ponds had vertical sides and were too deep (¯x = 0.42 m) to allow foraging. David E.

Breeding Bird Community Changes in a Bald Cypress-tupelo Wetland Following Timber Harvesting We determined immediate impacts of clearcutting on breeding bird communities of a tidally-influenced bald cypress (Taxodium distichum)-tupelo (Nyssa spp.) wetland located in the Mobile-Tensaw River Delta, Baldwin County, Alabama, April-June 1987. Seventeen of 45 species detected in first-year clearcuts, forestclearcut edges, and 70-year-old reference stands demonstrated significant (P <0.05) differences in abundance across habitat type. Three species preferred forest interior, 5 preferred edge, 7 preferred interior and edge over clearcut, and 1 preferred clearcut and edge (P <0.05). Laura J. Mitchell, R. A. Lancia

Evaluation of Bias in the Proportion of White-tailed Deer Fawns Sighted from Helicopters We marked fawns and adult white-tailed deer (Odocoileus virginianus) on 2 south Texas areas during 1986-88. Deer sighted on repeated helicopter flights were evaluated to determine if the age ratio of sightings matched the known ratio of marked fawns-to-adults in the populations. There was a trend toward undercounting fawns on each area. Joseph B. Sullivan, C. A. DeYoung, S. L. Beasom, J. R. Heffelfinger, S. P. Coughlin, M. W. Hellickson

Implications of September Hunting on Wood Duck Brood Production on the Holston River in Tennessee Wood duck (Aix sponsa) broods were counted 15 of 19 years (1973-90) using the night-float technique on a 1O.8-km segment of the Holston River, eastern Tennessee. Broods were counted 9 years before and 6 years after the initiation of September hunting seasons. Mean harvest (¯x = 26,797, SE = 2,130) of wood ducks in Tennessee after September hunting began was 279% higher (t = 7.50, P = 0.0001, df = 14) than the mean harvest (¯x = 9,604, SE = 845) before September hunting.
