A life history study of spotted seatrout (Cynoscion nebulosus) was conducted in Calcasieu Lake, Louisiana, from January 1976 through December 1983. This species was found to be essentially non-migratory, as it appears to spend most of the year within Calcasieu Lake. Most spawning takes place during July and August. Fecundity values for various length classes captured in 4.1-, 4.4-, and 5.1-cm bar mesh monofilament gill nets demonstrated that spotted seatrout taken with the 4.1-cm bar mesh contributed greater spawning power than fish caught in both the 4.4-cm and 5.1-cm combined.

Food Habits of Sand Seatrout in Barataria Bay, Louisiana Food habits of 591 sand seatrout (Cynoscion arenarius) (Ginsburg) from Barataria Bay, Louisiana, were characterized. Overall, fishes and crustaceans were the most important food organisms. Mysid shrimp were dominant food items in sand seatrout <100 mm whereas bay anchovy and brown shrimp were predominate in the larger fish. Sand seatrout generally preyed upon a relatively small number of species or taxonomic groups. Richard A. Kasprzak, Vincent Guillory

Survival of Hook-Caught Spotted Seatrout Spotted seatrout (Cynoscion nebulosus) (242-585 mm total length) were captured by hook and line in 7 Texas bay systems and placed in wire cages during June to September 1981 and December 1982 to April 1983 to estimate survival of hook-caught handled fish. No significant difference (P> 0.05) in survival was found between fish which received a wide range of handling stress such as sport fisherman might handle them and fish handled carefully as controls. No significant difference (P> 0.05) was found among summer and winter survival of hook and line caught spotted seatrout. H. E. Hegen, G. E. Saul, G. C. Matlock

Gonadal Condition of Hard Clams in a South Carolina Estuary Gonadal condition of hard clams (Mercenaria mercenaria) planted at 2 tidal locations and at 3 population densities were evaluated in relation to age, size, sex, season, and culture condition. Changes in gonadal-somatic indices (GSI) reflected seasonal differences in gonadal development. Similar decreases in GSI were observed during the spring (May-Jun) and fall (Sep-Oct) spawning peaks. GSI varied significantly (P < 0.0001) with clam size and age. Larger clams had proportionally more gonadal tissue than smaller clams of the same age. Arnold G. Eversole, William K. Michener, Peter J.

A 1-year creel survey of New River, Virginia and West Virginia, was conducted to assess the effects of a 305-mm minimum length limit on the angler harvest of smallmouth bass (Micropterus dolomieui) and associated fishes from the Virginia portion of the New River. Anglers in Virginia harvested 0.06 smallmouth bass per hour averaging 322 mm total length (TL) and released 1.27 smallmouth bass per hour. West Virginia anglers harvested 0.40 smallmouth bass per hour averaging 242 mm TL and released 0.65 smallmouth bass per hour. Douglas J. Austen, Donald J. Orth

From 1977 to 1983, non-uniform probability creel surveys were conducted on Lake Norman, North Carolina, and Lake Wylie, North Carolina and South Carolina, to estimate seasonal and annual creel parameters of pressure, success, harvest, and angler preference. Despite their geographical proximity on the Catawba River, mean annual pressure and harvest estimates on Lake Wylie were >3 times higher than respective estimates on Lake Norman. Catch rates for the 2 reservoirs were similar.

The Rainbow Trout Fishery in the Bull Shoals-Norfork Tailwaters, Arkansas, 1971-81 The catchable rainbow trout (Salmo gairdneri) fishery in the tailwaters of Bull Shoals and Norfork Dams, begun in 1948, has apparently reached equilibrium with respect to angler use and harvest. Angler days during 2 creel studies (1971-1973 and 1980-81) ranged from 139,000 (1973) to 272,000 (1981). Anglers harvested 46.1 % to 98.4% of the 800,000 to 880,000 rainbow trout stocked annually. Stocking schedules were tailored to well-established patterns of spatial and seasonal angler use.

Results of Lake Powell, Virginia, Creel Census from 1970 to 1983 Creel census data for a 14-year period (1970-1983) from Lake Powell show a high quality fishery for this 25.1-ha lake. Fishing pressure averaged 203.8 hours/ha/year, and the total fish harvest averaged 191.8 kg/ha/year. Average annual harvests of the major game species were: 62.4 kg/ha, bluegill (Lepomis macrochirus); 11.6 kg/ha, redear sunfish, (L. microlophus); 11.9 kg/ha, black crappie (Pomoxis nigromaculatus); 10.5 kg/ha, largemouth bass (Micropterus salmoides); and 4.8 kg/ha, chain pickerel (Esox niger). Average weights of the creeled pan fishes were well above normal.

Catch/Release Bias in Reward Tag Exploitation Studies A post card survey questionnaire was used to obtain information about the catch and release practices of anglers participating in largemouth bass (Micropterus salmoides) tag reward exploitation studies at 2 North Carolina reservoirs. The surveys demonstrated that at least 60% of all tagged bass captured were released. The post card survey resulted in substantial reductions in the estimated exploitation rates at both reservoirs.

Increasing Creel Survey Efficiency: Early Termination of Survey on Inactive Days Estimates were made of the percent of sport-boat interviews and retained fish that would be missed by terminating weekend surveys early when no anglers have been seen prior to specified times. Surveys could be terminated at 1200 hours during the summer and not miss more than 2% of the total interviews within any 1 bay system. Fall, winter, and spring surveys could be terminated at 1400 hours and no more than 4% of the total interviews would be missed. The percent of surveys that could be terminated early is highest in winter (37%-67%) and lowest in summer and fall (2%-10%). Mike G. Weixelman, Albert W. Green

Production of Phytoplanktivorous Silver Carp in a Eutrophic Dairy Farm Impoundment Suitability of silver carp (Hypophthalmichthys molitrix) as a biological agent in controlling phytoplankton was studied in situ in 3 sequential dairy farm ponds in Anderson County, South Carolina. Concentrations of chlorophyll a, soluble orthophosphate and associated water quality parameters were measured biweekly from May 1979 through May 1980 prior to introduction of silver carp (100-150 mm total length; 23.1 g average weight) to 1 pond on 12 June 1980. Water chemistry measurements continued through October 1980. Teresa A. Wilson, Jeffrey W. Foltz, W. Randy Geddings

Tree and Shrub Planting Along Constructed Stream Channels in North Carolina Riparian vegetation has numerous, well recognized values to the stream ecosystem. In small watershed projects in North Carolina, the problem of maintaining and managing this riparian vegetation both during and after channel improvement is an important planning consideration. To date, efforts have largely concentrated on leaving existing trees along the channel bank during construction. Several problems have been encountered with this practice and alternative methods of managing riparian vegetation are being evaluated.

Effects of Excavation and Snagging on the Fish Populations of a Coastal Stream in North Carolina Island Creek, a tributary of the Northeast Cape Fear River in Duplin County, North Carolina, was modified through excavation and snagging during 1977 and 1978. To evaluate the effects on resident fish populations, rotenone samples were taken before alteration in 1977 and after the project in 1981 and 1982. Mean standing crop of fish increased from 27.5 to 38.3 kg/ha after the project and total number of fish captured increased from 424 to 1,058. Significantly greater (P < 0.05) centrarchid and total game fish biomass were found after the project. Kent L. Nelson, James C. Borawa

Distribution of Larval Fishes in a Lower Mississippi River Dike Field A study was conducted from April through October 1980 to characterize seasonal changes in distribution, diversity, and abundance of ichthyoplankton within the Cracraft dike field in the lower Mississippi River. During high river stages (April through June), diversity and abundance of larval fishes were greater at open-water than nearshore stations. Under moderate to low river stages (July through October), diversity was low and greatest densities of larval fishes were observed along the shoreline inside the middle bar rather than in the open-water.

A Field Training Officer Program in Wildlife Law Enforcement The Field Training Officer Program is 1 part of the total wildlife officer selection process. This is accomplished by selecting experienced senior officers and placing them in specialized seminars where they are taught how to assist, direct, and evaluate probationary officers in the field. The primary objective of the Field Training Officer Program is to introduce the recruit to actual work-related experiences and to bring the officer to a level that allows him to work alone in a safe, skillful and professional manner.

Boating Safety as it Co-exists with Wildlife Because of the nature of our work, fish and wildlife departments have traditionally been involved in boating safety. Even though many of the states have separate water patrol departments whose primary duties are policing the waterways, game agents find that a substantial amount of their time is spent providing public services on the water. This reality has forced many of our states to begin boating safety programs within their enforcement ranks and to accept these tasks as routine duties.

Airborne Hunting, A Wildlife Disaster The use of aircraft to hunt wild animals has been a problem in recent years. With the number of helicopters increasing every day, wildlife is threatened with potential disaster. Those few poachers that would take immoral, as well as illegal advantage of wild animals by hunting them from an aircraft, have the potential of destroying years of careful wildlife management. We in the wildlife law enforcement field must concentrate our efforts on stopping this type of illegal hunting.

Tennessee's Wildlife Observation Area Program The public generally has inadequate knowledge about 1) good places to observe quality wildlife populations and 2) habitat requirements for such populations. Wildlife observation areas are designed to help resolve both problems. Of 28 sites designated between 1981 and 1983, 75% are in cooperation with other agencies. Cooperative plans for each area are site-specific, but the owner-cooperator is normally the lead agency for enhancing wildlife observation opportunities and interpretative programs.

Monitoring the Fisheries and Wildlife Enterprise: A Content Analysis of Agency Annual Reports A content analysis of annual reports for 15 southeastern state fisheries and wildlife agencies revealed that resource information (e.g., habitat, populations, and use) appears much less frequently than administrative information (e.g., revenues, personnel, permit review). The “typical report” consists of 35% administrative, 28% fisheries, 16% facilities, 11% wildlife, and 11% public involvement information. States cluster into 4 groups based on relative emphasis of freshwater fisheries, freshwater and marine fisheries, wildlife, or facilities and administrative information. Barbara A. Knuth, Larry A.

Behaviors of Mississippi Nonindustrial Private Forest Landowners Toward Hunting A mail questionnaire was used to determine behaviors of Mississippi nonindustrial private forest landowners toward hunting on their lands. Seventy-three percent (516 of 704) of the questionnaires were returned. A telephone survey of nonrespondents indicated negligible bias in the mail survey. About 45% of the respondents posted their land and 43% allowed no hunting by the general public. At least 77% of the respondents allowed hunting on their lands. Since only 6% of the respondents leased hunting rights, most hunting was by the landowner, family or guests. David H. Nabi, D. C. Guynn, Jr., T. B. Wigley, S. P. Mott

Development and Impact of an Industrial Wildlife Program St. Regis Corporation has developed a multi-faceted wildlife program. The company's program has been successful in integrating wildlife management guidelines into its forest management practices. The wildlife department's responsibilities also include biological data collection from leasees, wildlife research, management of customer and guest hunting areas, and cooperative working relationships with staff and federal wildlife agencies. Hunting lease fees generated from the company's forest land fund the program. Charles E. Allen, J. G. Dickson

Deer Management Plans for Private Lands in Texas In 1979, the Texas Parks and Wildlife Department (TPWD) initiated a program permitting landowners with department-approved management plans to harvest antlerless deer (Odocoileus virginianus and O. hemionus) in numbers exceeding those recommended for general areas by the department. Preparation of management plans and problems encountered with the program are discussed.

A Comparison of Individual and Nest Survival of Mourning Doves and Implications to Nesting Studies Mourning dove (Zenaida macroura) nests were located on the Texas A&M University campus during the 1981-1982 nesting seasons. Daily survival rates, calculated using nests and individuals as units of analysis, were compared for eggs, nestlings, and eggs and nestlings combined. No difference (P > 0.05) was detected in any of the comparisons, indicating that equivalent data were obtained by knowing only the fate of the nest and not of individuals within the nest. Thus, disturbance at the nest can be minimized without loss of accuracy. Michael E. Morrow, N. J. Silvy

Differential Vulnerability of Fox and Gray Squirrel Age Classes to Hunting Age ratios were determined for 361 gray squirrels (Sciurus carolinensis) and 130 fox squirrels (S. niger) taken on 50 ha in Northeast Texas during 5 weekend hunts. Data indicated that adults were more likely than young to be taken on the opening weekend. During weeks 2 and 3, young were more frequently taken while during weeks 4 and 5, adults were again taken more frequently. Results were inconsistent with the beliefs of most biologists and hunters who claim that young animals are more susceptible to the gun than are adults. James R. Reynolds, N. J. Silvy

Preliminary Evaluation of Ruffed Grouse Restoration Efforts in Arkansas Ruffed grouse (Bonasa umbellus) restoration efforts were initiated in Arkansas in 1981, with the relocation of 50 wild-trapped birds from Cumberland Gap National Historical Park in Virginia to a release site in Newton County, Arkansas, along the Buffalo National River. In 1982, restoration efforts continued with the release of 67 Wild-trapped grouse captured in Virginia and Minnesota. These birds were released on the Buffalo National River site and on the Ozark National Forest in Johnson County. Larry D. Pharris, S. Chaney, M. Cartwright

Opossum Demography and Scent-Station Visitation in Western Tennessee Removal trapping was used to study opossum (Didelphis virginiana) demography at an upland site in western Tennessee during March 1983. Monthly differences in scent-station visitation were assessed at 5 western Tennessee localities, representing upland and lowland habitats, from April 1982 to May 1983. A density of 1 opossum/ 15.6 ha was determined using removal trapping. Yearlings made up 64% of the 14 animals captured. Adult and pouch-young sex ratios were approximately 100:100. Mean litter size was 8.8 young. Paul L. Leberg, M. L. Kennedy, R. A. Van Den Bussche

Bird Damage to Sprouting Corn in Kentucky and Tennessee Loss of corn sprouts to birds (predominantly common grackles, Quiscalus quiscula) was estimated in a O.5-ha plot in each of 270 fields in 36 counties in Kentucky in 1978 and 215 fields in 21 counties in Tennessee in 1979. Estimated loss of sprouts to birds in Kentucky and Tennessee averaged 0.15% (SE = 0.03) and 0.95% (SE = 0041), respectively, for a maximum projected grain harvest loss of about 4,600 metric tons in Kentucky and 12,400 metric tons in Tennessee.

Repelling Rat Snakes from Wood Duck Boxes with Chemical Barriers Potential chemical repellents against rat snake (Elaphe obsoleta) depredation of wood duck (Aix sponsa) nesting boxes were tested under controlled conditions on the Rum Creek Wildlife Management Area, Georgia. Two repellents (Tack Trap and a mixture of Tack Trap and pine gum) effectively repelled rat snakes from wood duck nesting structures under pen conditions (P<0.l 0). The stickiness of the repellent material and not the presence of pinosylvin phenols appeared to be the deterrent to rat snakes.

Growth, Production, and Wildlife Use of Delta Duckpotatoes in Louisiana Field studies of delta duckpotatoes (Sagittaria graminae var. platyphylla) disclosed that plant density was 1.5 times greater in wildlife exclosures than in control areas. Tuber production where nutrias (Myocastor coypus) and ducks were excluded was 652.3 g/m2• Tuber production was considerably less in plots subjected to foraging by wildlife (nutria foraging only: 104.7 g/m2, duck foraging only: 75.8 g/m2 , nutria and duck foraging: 64.8 g/m2 ). Tubers were found to a soil depth of 30 em but where animals were excluded greatest production (40.3%) was at the 10-15 cm depth. Robert H. Chabreck, B. K. Pilcher, A. B. Ensiminger

Winter Movements and Habitat Use by Wood Ducks in South Carolina Ten wood ducks (Aix sponsa) were radio-tracked during the wintering period on Steel Creek, Savannah River Plant, South Carolina. Home range size, daily movement and habitat use were determined from 1,140 radio-locations. Data collected during approximately 21 to 28 days of intensive radio-tracking were sufficient for delineating individual wintering wood duck home range size.. Males had significantly larger home ranges than females (42 ha vs 12 ha) and exhibited greater diurnal movements. G. R. Costanzo, T. T. Fendley, J. R. Sweeney

The Use of Cripples/Hit Versus Cripples/Shot in Comparing Wounding Losses for Lead and Steel Shot Two definitions of crippling rate, cripples! shot and cripples! hit, have been employed in field studies to compare waterfowl wounding losses for lead and steel shot. Properties of these 2 definitions were compared using the Louisiana Lacassine Study data (Hebert et al. 1982) and a mathematical model. Cripples! shot was shown to decrease to a limit of 0 with an increase in misses even though the actual number of cripples remains constant. Cripples! shot, and not cripples! hit, was subject to an interaction between load and distance. The susceptibility of cripples!

Avian Use of Small Aquatic Habitats in South Texas Monthly censuses for 18 months were taken of avian communities on 12 ponds in South Texas. Ponds were classified into 4 types: stock, semi-permanent pasture, semi-permanent field, and temporary field ponds. Thirty-eight families represented by 132 species and 17,912 individuals were observed. Anatidae, represented by 22 species and 7,839 individuals, had the highest importance value of any bird family. Bird densities were similar across all pond types within each of 3 major time periods. Ronald J. Briggs, D. D. Everett

A Validity Test of a Habitat Suitability Index Model for Clapper Rail A method of habitat assessment known as Habitat Evaluation Procedures has been developed by the U.S. Department of Interior Fish and Wildlife Service. A linear relationship is assumed to exist between an area's Habitat Suitability Index (HSI) and carrying capacity. The objective of this study was to determine whether an HSI model for clapper rail (Rallus longirostris) is valid for predicting habitat suitability for this species in Georgia. Call-count surveys were conducted for clapper rail on 12 40-ha areas of tidal salt marsh during the winter and the spring of 1982-1983.

Methodology for Assessing Timber and White-tailed Deer Habitat Tradeoffs A linear programming model was used to evaluate trade-offs between timber returns and white-tailed deer (Odocoileus virginianus ) habitat in East-Central Mississippi. The model was designed to maximize capitalized present net worth of a sample forest subject to white-tailed deer habitat, wood flow, and acreage regenerated restrictions. Four levels of habitat diversity were evaluated. Enhancing habitat diversity will cost, in terms of timber revenue foregone, between $2.08 and $30.711hectare per year. These cost estimates are not applicable to all loblolly pine (Pinus taeda) forests. C. William McKee, W. E. Killcreas, J. E. Waldrop

Quality White-tailed Deer Management on an East Texas Hunting Club A management plan was implemented for white-tailed deer (Odocoileus virginianus) on a 1,781-ha East Texas hunting club. Objectives included the improvement of the herd's age structure and antler quality by reducing the population density and by selective harvest. During the 3-year study, 145 antlerless deer and 60 antlered deer were harvested. In spite of the accelerated antlerless harvest, the population increased approximately 15% each year. These increases apparently were because of increased fawn production.

Quality of Spring Deer Diets on Louisiana Pine-Hardwood Sites Nutritional quality of diets selected by 3 tame deer (Odocoileus virginianus) during spring 1980 were determined on forested and clearcut, unburned pine-hardwood sites in central Louisiana. Diets were dominated by leafy browse from plants of moderate to high preference for wild deer. From mid-March to late May, nutritive values of deer diets decreased an average of 43.1% for crude protein, 56.9% for phosphorus, and 9.3% for digestibility. Deer diets from clearcuts were generally higher in nutritive value than diets from forests. Ronald E. Thill, H. F. Morris, Jr.

Comparison of Two Diet Analysis Techniques Applied to White-tailed Deer Paired rumen and fecal samples from 89 white-tailed deer (Odocoileus virginianus) collected in the South Carolina Coastal Plain were analyzed using standard macro- and micro-techniques, respectively. Compared to fecal analysis, rumen analysis identified fewer plant taxa per sample (P < 0.05). A significant correlation among mean percent weights of forage categories (P < 0.05) and taxa (P < 0.05) was found. Spearman's rank correlation coefficients for percent frequency of detection were also significant for forage categories (P < 0.05) and taxa (P < 0.05).

Social Grouping of White-tailed Deer in Shenandoah National Park, Virginia During 1982, 3,095 social groups of white-tailed deer (Odocoileus virginianus) were observed in Shenandoah National Park, Virginia. Both time of day (dawn, day, dusk, and night) and season of the year (spring, fawning, summer, breeding, and winter) had a significant effect on total deer/ group and numbers of adults, adult females, and adult males. Group size was largest at dusk (mean 2.7, range of 1 to 28), and slightly smaller at night (2.4, 1 to 21), at dawn (2.3, 1 to 10), and during the day (2.3, 1 to 13). Seasonally, group size was largest in winter (mean 3.4, range of 1 to 28). John J. Scanlon, M. R. Vaughan

Predation on White-tailed Deer Fawns by Bobcats, Foxes, and Alligators: Predator Assessment Forty-eight white-tailed deer fawns (Odocoileus virginianus) were marked during the spring and early summer of 1981 and 1982. Forty-one (85.4%) of these fawns died, 26 (63%) due to predation. In 18 of the 26 predator-caused deaths, the species of predator could be determined. Bobcats (Felis rufus) accounted for 12 deaths, while red foxes (Vulpes vulpes) , gray foxes (Urocyon cinereoargenteus) and alligators (A lligator mississipptensis) were responsible for a total of at least 6 fawn deaths. Criteria for determining predator damage are discussed. Marc B. Epstein, G. A. Feldhamer, R. L. Joyner

A Track Plot System to Monitor Habitat Use Difficulty in capturing a sufficient sample of white-tailed deer (Odocoileus virginianus) for a biotelemetry habitat use study led to the development of an alternative methOd using track plots. One-hundred 1 X 3 m plots/site were proportionately allocated by percentage area of distinct cover types, prior to random location in the 3 study areas. Results from 13 months of use indicated that the method was acceptable for monitoring habitat use patterns. Potential uses and problems are discussed. Comparisons with biotelemetry and direct observation data are made. Richard A. Ockenfels, J. A. Bissonette

A Live Trapping and Handling Technique for River Otter Capture and handling techniques developed by river otter (Lutra canadensis) trappers, were evaluated during a 3-year telemetric study in the coastal marsh of Louisiana. A modified No. 11 Victor leghold trap was found to be the most practical and efficient live trap for otters in a marsh habitat. A total of 30 otters were captured. Trap-related injuries were infrequent and not serious. Eighty-four percent of the captured otters sustained minor cuts or no injury at all. Trapped otter were handled safely and efficiently by means of a long-handled net. Mark G. Shirley, R. G. Linscombe, L. R. Sevin

An Analysis of Scent Station Response in Louisiana An annual scent station survey was conducted in Louisiana from 1978 through 1982 to determine relative abundance of bobcats (Felis rufus) and relate indices to geographical regions and habitat types. A total of 29 lines each with 50 stations per line was proportionally divided into 5 regions. The use of fatty acid scent resulted in an average visitation rate of 4.6% for bobcats, 9.7% for coyotes (Canis latrans), 7.3% for fox (Vulpes vulpes and Urocyon cinereoargenteus), 7.2% for raccoon (Procyon lotor), 11:8% for opossum (Didelphis virginiana) and 7.1% for skunk (Mephitis mephitis).

Evaluation of Snares, Leg-hold, and Conibear Traps for Beaver Control From December 1981 through July 1983, No.2 Kleflock snares, No.4 Victor leg-hold traps, and No. 330 Conibear traps were evaluated for beaver (Castor canadensis) control in Mississippi. No. 330 Conibears captured more (P < 0.10) beavers than did snares in dive sets and more (P < 0.01) beavers than any other set-type combination tested. The number of non-target species captured in snares was less (P < 0.01) than the number captured in either of the other devices. Economic analyses of vehicle, labor, and equipment costs/beaver captured showed No. Carl E. Mason, E. A. Gluesing, D. H. Arner

Spring and Summer Movements of Muskrats in a Louisiana Coastal Marsh Muskrat (Ondatra zibethicus rivalicius) movement and activity patterns were studied in a Louisiana coastal marsh. Trap success was 8.2% in January-February, but only 3.3% in June-August. Of 46 muskrats captured, 65.2% were males. Lodge use was greater than expected in JanuaryMarch and less than expected in April, July and August (X2 =92.5, N =557, P < 0.01). No radio-collared muskrats (11 males and 6 females) were observed rearing young. Five (33.3%) muskrats emigrated in the spring and 3 of the dispersals occurred during a storm tide (29 March- 3 April). David A. Dell, R. H. Chabreck, R. G. Linscombe
