Effects of Backpack Radio Packages on Mass of Captive-reared Mallards Released in Maryland Radio telemetry has been an invaluable technique to study waterfowl ecology, but impacts of radio packages on ducks have not been experimentally assessed during the non-breeding season. We tested the hypothesis that backpack-style radios with 2 body harness loops influenced the body mass dynamics of 8-week-old captive-reared mallards (Anas platyrhynchos) released in Maryland in August. We attached mock radio packages and visual markers to 477 experimental ducks and visual markers only to 582 control birds. Frank C. Rohwer, Kenneth D. Richkus, David B. Smith

Shrews in Managed Northern Hardwood Stands in the Allegheny Mountains of West Virginia Shrews are an abundant and important component of the mammalian fauna in central and southern Appalachian forested habitats. Because most soricids are small, cryptic, and difficult to survey, they typically have been underrepresented in research examining effects of forest management on small mammals. W. Mark Ford, Chris A. Dobony, John W. Edwards

The Use of the Special Search Warrant Team in Wildlife Covert Operations The Arkansas Game and Fish Commission's Law Enforcement Division has been using covert law enforcement operations since 1981. Due to documented increases in illegal commercialization of fish and wildlife resources in the state, the Commission's administrators restructured the covert unit increasing the number of full-time and part-time officers assigned to perform covert tasks. Renewed covert emphasis resulted in an increase in funding and training for covert officers, concentrating efforts to identify, apprehend, and prosecute violators. Lt. Chuck Woodson, Cpl.

Shift Assignments and Effective Conservation Law Enforcement The role of conservation law enforcement officers in the last half of the 20th Century expanded from enforcement powers used to ensure proper wildlife and fishery management to that of fully-certified state peace officers. Today, Florida Conservation Law Enforcement Officers are responsible for enforcing all state laws and applicable federal statutes. Officers have traditionally been provided latitude on when and where to work, largely because of the limited number of available positions to patrol vast geographic areas.

An Analysis of Mississippi Conservation Officer Satisfaction with Weaponless Tactics Training A survey was developed and administered to a population of Mississippi conservation law enforcement officers in order to elicit demographic characteristics and satisfaction with weaponless tactics training. One hundred and four of 253 (41%) surveys were returned for analysis. Respondents were classified based on having <5 years, 5-15 years, or >15 years service. In general, officers with more experience were likely to find weaponless tactics training important but only moderately so. Richard B. Minnis, Patrick L. Parker

Managing the Complex Issues Involved with Line-of-duty Death On 25 March 2002, an Alabama Conservation Enforcement Officer died of complications from a gunshot wound received while serving a search warrant. The Enforcement Section had no formal guidelines related to line-of-duty deaths at the time the officer died. Agencies should be prepared to deal with line-of-duty deaths and have formal guidelines in place to aid the agency in effectively managing the multitude of issues involved. Fish and wildlife enforcement is a high-risk profession and every agency has faced or will have to face this reality.

A Survey of Urban Deer Policies in 4 Southeastern States In the 20th Century, white-tailed deer (Odocoileus virginianus) populations in the United States increased dramatically. In many states, management objectives for deer have changed from conserve and increase to control and decrease. Diversity among stakeholder's objectives for deer populations has made management difficult. Many states in the northeastern and midwestern United States began struggling with urban deer management in the 1980s, whereas southeastern states have only recently encountered this challenge.

Attitudes of South Carolina Youth Towards Aquatic Resources and Recreational Fishing This study assessed South Carolina youths' attitudes toward, opinions on, knowledge of, and priorities toward South Carolina aquatic resources and recreational fishing. A telephone survey was administered to youth between the ages of 8 and 18 in South Carolina during April 2001 to examine fishing initiation, motivation, and fishing participation rates among South Carolina youth. Overall, a majority of youth (91%) in South Carolina had fished at least 1 time in their lives and a majority (53%) of youth would go fishing more often if they could. Mark D. Duda, Peter E.

Fall and Winter Brook Trout Prey Selection and Daily Ration Most studies examining salmonid diets and their relationship to invertebrate drift are confined to periods from spring through early fall. Invertebrate drift generally decreases from spring through summer and fall seasons and is greatest during diel periods of low light. Salmonid feeding efficiency is reduced under low light conditions and several studies have found them to feed primarily through the daylight hours. Drift feeding salmonids are also size selective.

Response of Brown Trout in Lake Cumberland Tailwater to a Trophy Regulation The objective of this study was to evaluate the use of a 508-mm minimum length limit in conjunction with a 1-fish-per-day creel limit to determine its effectiveness in improving the size structure of the brown trout (Salmo trutta) fishery resource in the Lake Cumberland Kentucky tailwater. The ultimate goal is to increase the number of trophy (>508 mm) brown trout within the tailwater. When sample sites were combined, a significant increase in brown trout CPUE was seen across years for all size-classes.

Development of a Bioenergetics Model for Appalachian Brook Trout In many Appalachian headwater streams brook trout (Salvelinus fontinalis) are the only fish species present. Land use practices or global warming can have a significant effect on the production and survival of brook trout in these streams. Managers must be able to evaluate the potential impact of thermal changes upon these streams and bioenergetics models represent a valuable tool in this effort. Here we present a bioenergetics model for brook trout and conduct a laboratory validation of the model.

Brook trout (Salvelinus fontinalis) is the only salmonid native to the southern Appalachian Mountains. The range of brook trout within this region was greatly reduced during the 20th century due to environmental degradation and the introduction of non-native rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta). Efforts to supplement trout populations and to repopulate streams in which trout had been extirpated also included stocking of hatchery-reared brook trout, the stocks for which originated from northern populations.

Biochemical Genetics of Brook Trout in Georgia: Management Implications Twenty-eight populations of brook trout (Salvelinus fontinalis) in Georgia were genetically compared using isozymes and their genetic relatedness determined. Eight populations (29%) were classified as southern based on fixation for CK-A2*122 allele, 2 (7%) populations were classified as northern based on fixation for CK-A2*100 allele, and the remaining 18 (64%) were northern-southern hybrid populations. All 8 southern populations shared some variant alleles with northern populations. Rex A. Dunham, Huseyin Kucuktas, Zhanjiang Liu, Lee Keefer, Michael Spencer

Quantifying Instream Habitat in the Upper Shavers Fork Basin at Multiple Spatial Scales Brook trout (Salvelinus fontinalis) populations in the upper Shavers Fork, a high elevation watershed in eastern West Virginia, have been severely impacted by a loss of quality habitat. Successful restoration of these populations will require a comprehensive understanding of current habitat conditions at a watershed scale. We describe a statistically based habitat survey designed to quantify physical habitat conditions within the watershed at a range of spatial scales. J.

On 11 October 2000, approximately 946.25 million liters of coal slurry waste spilled from a Martin County Coal Corporation impoundment into 2 stream drainages in Martin County, Kentucky. On the same day of the spill occurrence, water quality was assessed and periodic monitoring has continued to the present by state personnel from Kentucky and West Virginia. The resulting damage to fish in the streams was the focus of intensive investigation by both the Kentucky Department of Fish and Wildlife Resources and the West Virginia Department of Natural Resources.

Many fisheries management agencies incorporate benthic macroinvertebrate metrics in stream assessment, yet concern exists over regional variability in metric sensitivity and the reproducibility of results over time. Two field experiments were conducted in Mullenax Run, Pocahontas County, West Virginia during summers 1999 and 2000 to investigate the sensitivity of benthic macroinvertebrate metrics to fine sediment and annual variation.

Macroinvertebrate Forage in the Smith River Tailwater Benthic macroinvertebrates were sampled in July 2000 and April 2001 at 12 sites in the Smith River below Philpott Dam in southwestern Virginia. One riffle in each site was stratified into upstream, middle, and downstream transects and Surber samples were collected at 2 randomly-selected locations on each transect. Macroinvertebrates were identified to family and each sample was measured for wet weight. Family richness was calculated and simple linear regression was used to evaluate longitudinal trends in mean abundance and wet weight with increasing distance from the dam. T. J. Newcomb, K. M.

Genetic Analysis of Ozark Hellbenders Utilizing RAPD Markers Ozark hellbenders (Cryptobranchus alleganiensis bishopi) are large aquatic salamanders found in flowing waters. The abundance of this species is thought to have declined over the long term. What had been the most abundant population, in Spring River, Arkansas, appears to have declined precipitously in the last decade. The possibility of supplementing the population through captive propagation has been suggested, raising concerns about genetic issues. Huseyin Kucuktas, Brian K.

Comparison of In-Water Voltage Gradients Produced by Electrofishing Boats The voltage gradients of electric fields produced by electrofishing boats are important in determining sampling efficiency and the potential for injuring fish. We evaluated 10 electrofishing boats and found that 3 boats had malfunctions that could impact sampling or operator safety. The in-water voltage gradients were measured for the remaining 7 boats to make comparisons among boats and to determine the voltage gradients present during electrofishing. Theodore B. Henry, John M. Grizzle, Michael J. Maceina

Environmental Influences on Largemouth Bass Recruitment in a Southern Great Plains Reservoir We analyzed relationships between largemouth bass (Micropterus salmoides) recruitment and environmental characteristics in Skiatook Lake, Oklahoma, from 1997 through 1999. Catch rates of young-of-year (YOY) were positively associated with inflows into the reservoir during the spawning season (April-May), whereas juvenile catch rates were positively related to reservoir releases during the post-spawning period (Jun-Nov). Abundance of juvenile fish in fall electrofishing samples increased from 1997 through 1999. No evidence of over-winter mortality was detected. James M. Long, William L. Fisher

In temperate reservoirs, habitat quality and availability can be vital to year-class formation of young largemouth bass. We assessed littoral habitat availability for largemouth bass in a tropical reservoir. Habitat characteristics (slope, substratum, and cover) were measured at 5 water levels (169, 170, 171, 172, and 173 m above mean sea level) at 15 30-m sites in Lucchetti Reservoir. Total structural habitat availability declined sharply at lower water levels, and both inundated terrestrial vegetation and woody debris were absent at the lowest water level examined. J.

Seasonal Movement and Distribution of Smallmouth Bass in a Virginia Impoundment We described seasonal movements of smallmouth bass (Micropterus dolomieu) in Lake Moomaw, a 1,024-ha western Virginia impoundment, using ultrasonic telemetry in combination with a mark-recapture tagging study. Documentation of lake sections occupied over the course of a 2-year period was used to assess the extent and magnitude of spring migrations of bass to the headwaters of the reservoir. Fish using the headwaters during the spring were drawn mainly from adjacent areas within 9 km of the headwaters, although fish from as far away as the dam were recovered in the headwater area.

Relationships Between Diet and Growth of Age-0 Largemouth Bass in a Kentucky Lake Embayment Diet and growth of the 1993 year-class of age-0 largemouth bass were determined in Ledbetter Embayment of Kentucky Lake. Diet was analyzed to determine the relationship between diet quality and the resulting size structure of the cohort. Length-weight and head capsule-weight regressions were used to estimate the dry weight of prey items in the diet. Largemouth bass were divided into 2 size classes (large and small) based on the mean length for each sampling date. David P. Dreves, Tom J. Timmons

Briery Creek Lake is a 342-ha impoundment in central Virginia that has become widely recognized as having Virginia's premier trophy largemouth bass (Micropterus salmoides) fishery. We estimated largemouth bass density (fish/ha) using a multiple census mark-recapture technique along a 3.2-km section of shoreline and by using the Leslie catch-depletion technique in a 4.1-ha cove. An access point creel survey was conducted in 1999 and 2000 to estimate angler catch and harvest. Victor J. DiCenzo, Daniel A. Garren

Relation of Environmental Calcium and pH to the Stress Response of Striped Bass Striped bass fingerlings (Morone saxatilis) acclimated to hard water (110 mg/liter as calcium carbonate, 41.0 mg/liter as calcium) were exposed for 96 hours at pH 7.7, 6.1, or 4.2 in hard water. In another experiment, striped bass fingerlings acclimated to soft water (32 mg/liter as calcium carbonate, 9.5 mg/liter as calcium) were exposed for 96 h at pH 7.7, 6.1, or 4.2 in soft water. No mortalities occurred during the experiments. Patricia M. Mazik, Bill A. Simco, Nick C. Parker

Effect of Calcium Hardness on Channel, Blue, and Channel x Blue Catfish Hybrids The aquifer that supplies water to most channel catfish (Ictalurus punctatus) hatcheries in the Yazoo Basin of the Mississippi River flood plain in west-central Mississippi has a hardness of <10 mg/liter as CaCO3. Calcium hardness <10 mg/liter is known to reduce survival and growth of catfish sac and swim-up fry, but effects of low hardness on fingerling growth and survival have not been determined. We examined the effects of hardness (5 mg/liter and 67 mg/liter as CaCO3) on survival and growth of fingerling (2.0-3.2 g initial weight) channel catfish (USDA-103 line), blue catfish (I. Eugene L.

A Precocious Population of Channel Catfish with Potential as a Research Model A population of catfish presumptively identified as channel catfish (Ictalurus punctatus) found in Lake Maurepas in southeast Louisiana matures at a small size and early age (<170 mm TL and <2 years) compared to other populations in southern Louisiana (>500 mm TL and 3 to 4 years). In addition, these catfish have a protracted spawning period. The peak spawning time coincides with cultured channel catfish, but a percentage of the population spawns throughout the summer months. These fish are harvested at a small size and support an important but contentious commercial fishery. Mark C. Bates, Terrence R. Tiersch, Quiyang Zhang, Mark G. McElroy

Monitoring Free Copper to Determine Application Rates of Copper Sulfate: A Case Study Algae infestations are a common problem in catfish culture ponds. To treat filamentous algae, frequent applications of copper sulfate are necessary. Free copper is toxic to fish, and its concentration is dependent on a variety of factors such as its reaction with carbonate ions, absorption by phytoplankton, and temperature. The Frankfort Fish Hatchery has been using a colorimeter to measure the concentration of free copper ion after the application of copper sulfate to ponds stocked with blue catfish and channel catfish fingerlings.

The Case for Multi-jurisdictional Management of Ohio River Paddlefish The paddlefish (Polyodon spathula) population in the Ohio River Basin is an inter-jurisdictional resource shared by 8 states and managed with 3 different strategies, restoration, protection, and harvest. These contrasting management strategies evolved from a historical gradient in abundance of paddlefish from the upper to lower reaches, differential impact of anthropogenic factors, and U.S. Supreme Court settlements, which changed river ownership among lower Ohio River states.

Walleye Movement, Distribution, and Habitat Use in Laurel River Lake, Kentucky Movement, distribution, and habitat use of walleyes (Stizostedion vitreum) in Laurel River Lake, Kentucky were determined by radio-tracking 35 walleyes for 605 days (mean = 249 days) from March 1994 through November 1995. The goal of this study was to increase the angler utilization of walleyes in Laurel River Lake by educating anglers on walleye movement patterns, habitat usage, and distribution within the lake. Walleye movement (as measured in distance between weekly locations) was highest during the spring (median = 120 m/day) and lowest during the summer (median = 53 m/day).

Although fertilization has been a common practice to increase fish production in low nutrient lakes and ponds, applicability of the practice in larger reservoirs is questionable. Under the assumption that increased algal production moves up the food web to fish, we fertilized Grayson Lake, Kentucky, surface water with high N to P ratio fertilizer during springs 1994 and 1995. April through July 1994 we added 1 kg P/ha and 22 kg N/ha over a 9-week period to approximately 162 ha of lake surface area. During 1995 we increased loading to 7 kg P/ha with 22 kg N/ha. Brian C.

Movement and Habitat Use of Subadult Gulf Sturgeon in Choctawhatchee Bay, Florida The Gulf sturgeon (Acipenser oxyrinchus desotoi) is a threatened anadromous species in the Gulf of Mexico. Nineteen subadult Gulf sturgeon were equipped with ultrasonic transmitters (34-40 kHz) in the Choctawhatchee River and Bay during fall 1996 and 1997 before their entry into marine habitat. The movement and habitat use of Gulf sturgeon in the estuarine/marine environment was determined from November through April 1996-1999. A total of 344 sonic contacts were made in this study. Frank M.

Movement of Shortnose Sturgeon in the Upper Chesapeake Bay, Maryland Little published information exists on shortnose sturgeon (Acipenser brevirostrum) in the Chesapeake Bay. During a reward program for Atlantic sturgeon (Acipenser oxyrinchus), 32 shortnose sturgeon were captured in the Chesapeake Bay and reported by commercial watermen between January 1996 and January 2000. Thirteen of the 32 shortnose sturgeon were sonically tagged, and 6 of these telemetered individuals were tracked during daylight hours within the upper Chesapeake Bay. The distance (km) and time (days) between consecutive relocations were use to estimate movement rates as km/day. Stuart A. Welsh, Michael F. Mangold, Sheila M. Eyler

Response of the Crappie Population to Regulatory Changes in Kentucky Lake, Kentucky: A Case History The objective of this case history was to document the response of the crappie (Pomoxis spp.) population at Kentucky Lake to restrictive harvest regulations. In the late 1980s and early 1990s, crappie abundance declined due to poor recruitment and high mortality during severe drought years. A tagging study estimated minimum exploitation at 45%. Following the drought, restrictive harvest regulations (30 fish creel and 254 mm minimum length limit) were implemented to reduce exploitation, and subsequently increase survival of crappie from age 1 to age 2.

Lake Norman Striped Bass Management: A Conflict between Fishery Managers and Anglers The North Carolina Wildlife Resources Commission (WRC) stocks striped bass (Morone saxatilis) fingerlings in Lake Norman to support a put-grow-and-take fishery. Members from 2 angling groups demanded the WRC raise striped bass stocking rates and increase available striped bass forage. The agency contended increasing stocking rates would exacerbate poor condition and slow growth among the lake's striped bass. Conflict between the WRC and anglers arose when the agency indicated it would not raise striped bass stocking rates, stock additional clupeids, or introduce alosids.

Lake Tanglewood, Texas, is a eutrophic reservoir with an excessively abundant gizzard shad Dorosoma cepedianum population comprised of primarily large individuals (>180 mm total length [TL]). Fingerling (40 mm TL) hybrid striped bass (Morone saxatilis x M. chrysops) were stocked at high rates in 1992 (490/ha) and 1993 (245/ha) to restructure the gizzard shad population. Small gizzard shad (<180 mm TL) declined in abundance 1 year after hybrid striped bass were introduced, presumably as a result of hybrid striped bass predation. Kenneth G. Ostrand, Harold L.

Assessment of a 178-mm Minimum Length Limit on Bluegill at Purtis Creek State Park Lake, Texas We compared relative abundance, size distribution, growth, and harvest of bluegill (Lepomis macrochirus) before and after implementation of a 178-mm minimum length limit at 144-ha Purtis Creek State Park Lake (PCSPL), Texas. Relative abundance [catch/hour of electrofishing (CPUE)] was significantly lower in post-regulation years (1993-1995, 243/hour) than in pre-regulation years (1990-1992, 520/hour). However, this decline was likely more attributed to recruitment patterns than to regulation effects. Richard A. Ott, Jr., Timothy J. Bister, J. Warren Schlechte

Comparison of Feeding Regime and Diet on Compensatory Growth of Hybrid Bluegill We conducted 2 experiments to evaluate the potential of feeding schedules designed to elicit compensatory growth and increase growth of hybrid bluegill (F1: male bluegill Lepomis macrochirus x female L. cyanellus). The first experiment evaluated a commercially prepared pellet and consisted of 3 treatments: fish fed every day and fish starved for 2 or 4 days after cessation of hyperphagia. The second experiment evaluated 2 diets, mealworms and commercial pellets, fed every day and on a 2-day starvation schedule. Clifton R. Sager, Dana L. Winkelman

Temporal Change in Fish Assemblages of Triplett Creek, Kentucky Historical records and natural history collections have been used as important tools to determine the status of populations. The objectives of this project were to compile a list of the fishes that have inhabited Triplett Creek and to identify changes in the fish assemblage in Triplett Creek. Historical records and vouchered specimens document 80 species from 19 families in the Triplett Creek system between 1890 and 1998. In a survey of the Triplett Creek system in 1999 and 2000, 16,554 specimens were collected, representing 54 species from 11 families. Katherine A. McCafferty, David J. Eisenhour

Allegheny woodrat (neotoma magister) populations in the northern and western limits of the range have been greatly reduced in recent years, increasing the need to locate and monitor both threatened and seemingly stable populations. We tested the feasibility of predicting areas of suitable habitat for the woodrat in the Daniel Boone National Forest (DBNF) by using a Geographic Information System model. Several themes depicting woodrat habitat variables were overlaid to produce a comprehensive map displaying likelihood of woodrat occurrence. Eric S. Ivanovich, Stephen Sumithran, Robert B. Frederick

Fire Impacts to Small Mammals in Piedmont Oak-shelterwoods Successful regeneration of oaks on better sites (SI50>60) has proven difficult in recent decades due to competition from faster growing species and well-established advanced regeneration from more shade-tolerant species. The suppression of fire is thought to have played a critical role in allowing this largely fire-intolerant competition to dominate many upland hardwood forests at the expense of oaks. Patrick D.

Non-target Captures During Small Mammal Trapping with Snap Traps There is little published information available on non-target captures during small mammal trapping. We used a variety of snap traps baited with a rolled oat-peanut butter mix to capture 2,054 individuals from 9 genera of small mammals in a study of small mammal and avian community structure in riparian areas and adjacent loblolly pine (Pinus taeda) plantations. We also captured 170 individuals from 24 non-target species over 122,446 trap-nights. David G. Peitz, Philip A. Tappe, Ronald E. Thill, Roger W. Perry, M. Anthony Melchiors, T. Bently Wigley

Status and Management of Endangered Bats in Kentucky Three species of bats are endangered in Kentucky: the Indiana bat (Myotis sodalis), the gray bat (M. grisescens), and the Virginia big-eared bat (Corynorhinus townsendii virginianus). Because some level of monitoring of these bats has taken place at Kentucky caves for several decades, trends can be assessed and some effects of management practices can be evaluated. In Kentucky, populations of Indiana bats continue to decline despite numerous protection efforts, populations of gray bats appear stable, and populations of Virginia big-eared bats are increasing.

Initial Gray Squirrel Population Responses to Nest Boxes in Two Forest Types in Southern Alabama We studied short-term response of gray squirrel (Sciurus carolinensis) populations to nest boxes in mixed-pine (Pinus spp) hardwood and even-aged pine forests in Alabama from December 1988 to September 1990. Nest boxes (5/ha) were installed in 3 mixed pine-hardwood and 3 even-aged pine stands. We used a split-plot design to determine if populations differed between treatment (with nest boxes) and control (without nest boxes) halves of mixed pine-hardwood areas. Thomas E. Nupp, Nicholas R.

The Taxonomic Status of Wild Canis in Kentucky We assessed taxonomic status of wild canids in Kentucky using 13 cranial measurements on 143 known canid skulls in a multivariate statistical procedure to classify 56 unknown canid skulls from Kentucky. Discriminant function analyses revealed complete separation of canid taxa between coyotes and dogs, although coyote-dog hybrids had significant overlap with coyotes. Hybridization between coyotes and dogs in Kentucky occurred in less than 10% of unidentified canids. Our findings suggest that wild canids in Kentucky are best classified as coyotes, Canis latrans.
