Fall Foods of Adult Alligators from Cypress Lake Habitat, Lousiana

Stomachs from 111 adult-size (~1.83 m) alligators (Alligator mississippiensis) were collected during September 1981 and 1982. Alligators were harvested from cypress (Taxodium distichum) lake habitat. Reptiles and amphibians ranked highest in frequency of occurrence, but mammals were the most important food items in percent weight and percent volume. Reptiles and amphibians, primarily turtles, were second in importance, followed closely by fish, primarily non-game species. Non-food items comprised almost 25% of stomach contents by weight and volume.

Capabilities of Hunters to Shoot and Retrieve Free-swimming Alligators

Wildlife agency personnel monitored 70 hunters using centerfire weapons and shotguns to take free-swimming American alligators (Alligator mississippiensis) at a managed freshwater marsh in southeast Texas. One or more shots were fired by 64 hunters at 117 alligators of which 43 alligators were killed and retrieved; a minimum of 17 were visibly hit but not retrieved. There was no association between the outcome of a specific shooting event and the method of hunting, size of the alligator, or distance at which shots were initiated.

Selected Public's Reaction Following Harvest of American Alligators

People (N = 1,2(0) with first hand knowledge of American alligators (Alligator mississippiensis) were interviewed in October 1982 by questionnaire to determine observability and reaction following harvest on Newnanas Lake, Alachua County, Florida. Of 353 respondents, 60% enjoyed seeing alligators, and 52% attributed a decline in abundance to harvest. Most (76%) approved of harvest, but 20% believed it was part of the nuisance alligator program. No differences (P > 0.05) were detected concerning harvest approval when compared by age, sex, and user group.

Can Sun and Moon Charts Predict Wildlife Activity?

Systems claiming to predict fish and wildlife activity based on solar and lunar gravitational forces are popular among sportsmen. If valid, these could have implications for wildlife management. Two such systems, the Solunar Tables® and Fish and Game Forecastet, were evaluated using data from free-ranging and captive birds and mammals. Neither system accurately or consistently predicted activity, although some data sets revealed suggestive relationships.

Food Habits of the Coyote in Tennessee

During 1981-1984, digestive tracts of 262 coyotes (Canis latrans) from Tennessee were examined for food items, and data were assessed in relation to sex, age, seasonal, annual, and spatial variation. Foods with highest percent occurrence were rodent, persimmon (Diospyros virginia), rabbit (Sylvilagus spp), and whitetailed deer (Odocoileus virginianus). There were no differences between sexes and for foods eaten, and only persimmon varied significantly among age classes. Seasonal variation was found for rodent, insect, reptile and amphibian, opossum (Didelphis virginiana), and persimmon.

Experimental Relocation of Ruffed Grouse to the Georgia Piedmont

Forty-five ruffed grouse (Bonasa umbellus) were relocated in late summer 1984 from the Blue Ridge Mountains to the Piedmont of Georgia to assess the feasibility of establishing huntable populations. Nineteen radio-equipped birds survived 2 to 183 days (x = 82 days). Radio-monitored grouse preferred hardwood scrub habitats, sparse hardwood sawtimber, and bottomland hardwoods-all of which had high understory stem densities. Unradioed grouse were observed periodically from release until spring of 1985, but there was no evidence of reproduction.

Harvest Analysis of a Maryland Gray Squirrel Population

Gray squirrel (Sciurus carolinensis) harvest was investigated on a 2,320-ha Maryland study area from 1976 through 1981 using harvest/recovery estimates (Brownie et al. 1978) of marked squirrels. The minimum percentage removed by hunters was estimated to be 7% of adults and 9% of young and subadults. Hunting pressure, expressed as the number of trips, averaged 1,641 annually over a 17-week season with the majority (95%) occurring in the first 6 weeks. Average annual survival rate estimates were 0.52 for adults and 0.46 for subadults and young. However, survival esimates were variable.

Improved Efficiency in Aerial Surveys of Waterfowl using Catfish Ponds

Data from 2 aerial surveys of waterfowl using catfish ponds were used to compare sampling efficiences between 2 stratified sampling designs and 2 completely random designs. Completely random designs produced slightly lower coefficients of variation (CV) than post-stratified sampling designs. The unbiased estimator was simplest to compute. Based on a curve established from proportions of catfish ponds sampled and CV's, sampling intensity may be reduced if lower levels of precision were acceptable.

Brood Habitat Use and Preference by Wild Turkeys in Central Mississippi

Brood habitat use and preference by eastern wild turkey hens (Meleagris gallopavo silvestris) were studied by radio telemetry in central Mississippi in 1984 and 1985. Habitat use and preference were determined for 11 broods in the 1-14 days age group and 8 broods in the 1-84 days age group. Mature bottomland hardwood forests with a continuous canopy, sparse shrub and understory, and moderate herbaceous (grasses, forbs, vines, sedges) ground cover were highly perferred (P ≤ 0.05) brood habitat for both age periods.

Habitat Use by Eastern Wild Turkey Hens in Southeastern Louisiana

Seventeen female eastern wild turkeys (Meleagris gallopavo silvestris) were fitted with transmitters and monitored continuously during March 1984-May 1985. Mean home range for 4 hens that survived the 15-month study period was 677 ha. Adult (i = 66 ha) and subadult (i = 149 ha) home ranges differed (P < 0.05) during spring and may be related to nesting activities. Mean home ranges during summer, fall, and winter were 124,402, and 254 ha, respectively. Average distance traveled in 24 hours did not differ (P > 0.05) between age classes or among seasons.

Nutritional Effects on Thyroids, Ovaries, and Thymuses in White-tailed Deer

Forty-four adult (;;'2.5 years) white-tailed deer (Odocoileus virginianus) does were separated into 9 groups. Each group was offered a paired combination diet of high, medium, or low protein; and high, medium, or low digestible energy (DE) for a 60-day period ending December 1983 (Study I). Forty-six adult does were maintained on a paired combination diet of high or low protein and high or low digestible energy for a 6-month period ending December 1984 (Study II). Thyroid gland activity data were collected only from deer in Study II.

Weight Gain of White-tailed Deer Fawns Relative to Fawning Date

Fifty-two white-tailed deer fawns (Odocoileus virginianus) were obtained from penned breeding stock (31) and wild captures (21) during the 1985 fawning period. Birth dates ranged from mid-April to late August. Fawns were reared in pens on evaporated milk. Water and calf starter were provided ad libitum. Fawns were weighed at 2 week intervals. Birth weights recorded for 23 fawns and estimated for 8 fawns of known birth date, differed (P ≤ 0.05) among early, middle, and late born fawns.

Assessment of Fawn Breeding in a South Carolina Deer Herd

Annual variation in breeding success among female white-tailed deer (Odocoileus virginianus) fawns on the Savannah River Plant (1967 to 1985) was determined from direct counts of pregnancy in spring-collected fawn females and evidence of lactation and measurements of udder thickness in fall-harvested 1.5-yearolds. Percent lactation in 1.5-year-old females collected during September and October gave the best estimate of fawn breeding in the previous year. The overall mean fawn breeding estimate from September and October was 41 %, and the yearly variation in fawn breeding was significant.

Hand-reared Mallard Releases on 3 Private Farms in Maryland

Histories of releasing and hunting hand-reared mallards (Anas platyrhynchos) on 3 private farms in Maryland were examined. Since 1962, 171,800 mallards were released; annual releases now total 7,300 birds. Hand-reared mallards averaged 65-90% of the ducks harvested on the 3 farms. Hunters on the farms harvested 24-43% of the mallards released during 1980-84; hunters off the farms harvested an additional 4-11 %. Hand-reared mallards were sedentary; 83% were harvested on the release sites, and an additional 14% within 79 km.

Status and Population Affiliation of Canada Geese Wintering in North and South Carolina

Numbers of Canada geese (Branta canadensis) wintering in North and South Carolina have continued to decline since the mid-1960s. Observations (N = 2,027) from 2,563 neckbanded geese, marked during fall and winter 1983-85, indicate that birds from eastern North Carolina are distinct in migration pattern from birds wintering in South Carolina and probably the Piedmont region of North Carolina. Most sightings (85%) of eastern North Carolina birds, reported from outside the state, were from Maryland, Delaware, and Virginia.

Survival and Recovery Rates of Canada Geese from Maryland and North Carolina 1963-1974

State and federal personnel banded 4,960 Canada geese (Branta canadensis) in North Carolina and 11,522 in Maryland from 1963-1974. Adult survival for Maryland geese was estimated as 81.96% (SE = 0.88%) and for North Carolina geese as 79.23% (SE = 0.96%) indicating that geese banded in Maryland had a higher average annual survival rate (P < 0.01). Recovery rates also indicated Canada geese from North Carolina (3.01 %, SE = 0.16%) may have had higher rates of harvest compared to Maryland (2.39%, SE = 0.10%) (P < 0.001).

Lesser Scaup Mortality from Commercial Trotlines on Lake Okeechobee, Florida

Mortality of lesser scaup (Aythya affinis) from commercial trotlines was studied on Lake Okeechobee, Florida, from November 1985 to March 1986. Of 27 scaup removed from 118 trotlines, 81% were hooked in body parts other than the mouth. An estimated 7,458 scaup, or 8% of the estimated average winter population of 97,071, were killed during 5,675 man-days of fishing. Potential impacts on scaup populations are discussed.

Implications of Migration Chronology upon Waterfowl Harvest Opportunities in Florida

Duck migration chronology was determined for 11 national wildlife refuges (NWRs) in Florida during 1976-81. Mean monthly population indices differed by month, with peak populations occurring in December. Extension of the duck hunting season framework until 31 January, with a concurrent reduction of season days in December probably would reduce the statewide duck harvest. Implications of this harvest strategy are discussed in terms of hunter satisfaction and possible duck population impacts.

Landowner-reported Beaver Damage in the Arkansas Delta

Landowner perceptions of damage caused by beavers (Castor canadensis) in the Arkansas Delta were determined by mail survey. Beavers were reported on lands owned by 64% of the 460 respondents. Blocked culverts, flooded row crops, and girdled timber were the most common forms of damage. Of those with beavers on their lands, 90% requested decreased populations and 72% had tried removing beavers. Many landowners were unfamiliar with accepted control methods and where to get assistance.

Study of Factors Affecting Wildlife Law Enforcement Agent Productivity

The relationships of environmental factors, agent personal background, enforcement methods, and season with enforcement efficiency were analyzed. Three major interactions among independent variables were detected. Analysis of covariance by multiple regression indicated that methods of enforcement were more closely associated with enforcement efficiency than other categories of independent variables. Agent rank was found to be more strongly related to the dependent variable than the single most important environmental attribute (intensity of water recreation).

Evaluating the Effectiveness of Conservation Evaluation

Conservation education is an area of increasing emphasis and priority in state wildlife agencies throughout the United States. Where programs involve elementary and secondary school students and teachers, there are a set of responsibilities and expectations coming from that education community which in turn affect the state wildlife agencies. In addition, under any ground rules, state wildlife agencies have their own goals, and want to be able to assess their effectiveness in accomplishing those goals.

Size and Age Structure of a Single School of Striped Bass in Lake Greeson, Arkansas

A school of 206 striped bass, Marone saxatilis, were sampled using rotenone in a deep, southwest Arkansas reservoir. Fish averaged 439 mm TL and 823 g in weight, ranging in size from 321 to 525 mm TL and 33.5-1,389 g. K factors were extremely low, ranging from 0.82 to 1.18. Two hundred four of the striped bass were age II+ (1981 year class), while only 2 were age I+. Several possible reasons are considered as the causative agent in the formation of this large school.

Harvest Potential of Paddlefish Stocks in Watts Bar Reservoir, Tennessee

Mark-recapture techniques were used during spring 1982 and 1983 to estimate the abundance of harvestable size paddlefish (Polyodon spathula) in Watts Bar Reservoir, Tennessee. Results indicated a harvestable population in 1982 of 3,421 fish (95% confidence interval of 2,184 to 6,665). Aging studies indicated a relatively young population with an abrupt decrease in survival after the ninth year. This decrease was attributed to extreme fishing mortality on these older age classes before July 1980 when Watts Bar Reservoir was closed to net fishing.

Spatial And Temporal Distribution Of Larval Alewives And Gizzard Shad in a Virginia Reservoir

Compatibility and complementarity of age-O alewife and gizzard shad as coexistent forage fishes were evaluated through analysis of their distribution, spawning periods, and growth rates in Smith Mountain Lake, Virginia, in 1983. Gizzard shad larvae appeared to be confined to the upper reservoir and alewife larvae to the down-lake region. Spatial segregation prevents direct trophic competition while increasing potential feeding encounters for juvenile piscivores. Gizzard shad spawning peaked in June; alewife spawning peaked in July.

Food habits of smallmouth bass (Micropterus dolomieui) in the New River were studied to compare diet of fish in a minimum length limit regulated section (Virginia) with those in a non-length limit regulated section (West Virginia). Insects were the dominant food type by number for 152-228 mm smallmouth bass in both sections. Numerically, insects were also found to be common in smallmouth bass of several other size categories. Crayfish and fish, however, combined to form a large part of the diet of smallmouth bass greater than 228 mm.

Competitive Influences of Gizzard Shad on Largemouth Bass and Bluegill in Small Impoundments

Studies in large and small ponds conducted on the Auburn University Fisheries Research Station from 1981 through 1983 suggest that gizzard shad (Dorosoma cepedianum) severely competed with largemouth bass (Micropterus salmoides) and bluegill (Lepomis macrochirus) populations. Gizzard shad introductions lowered bluegill reproductive success and caused an imbalance the first year of introduction. Gizzard shad grew rapidly through the size range where they were vulnerable to largemouth bass predation; in this 3-year study, largemouth bass were unable to control gizzard shad numbers.

Reproductive Migrations of American Eels in Georgia

Information on silver American eels was obtained over a three-year period from seasonal sampling of 4 Georgia rivers, commercial fishermen, and from systematic sampling of eels migrating from a pond. All silver eels were captured from October through March. Of 80 animals examined, 73 were male and averaged 329mm, 69 g, and 5.5 years. Seven females averaged 584 mm, 448 g, and 8.6 years. These findings suggest that silver eels leave Georgia waters later in the year and at younger ages and smaller sizes than eels at more northerly latitudes.

Contamination From Battery Salvage Operations On The Chipola River, Florida

Trace elements (As, Cd, Cr, Cu, Hg, Pb, Se, and Zn) were measured in fish, clams, and sediment in 1982 to determine whether the effluents from 2 abandoned battery salvage operations were contaminating the Chipola River, Florida. Concentrations of the metals were generally low, but tended to increase downstream from plant sites. Elevated concentrations may reflect residual contamination from the battery salvage operations as well as increased land-use development and proximity to major highways.

Food Habits and Diet Overlap of Larval Lepomis spp. and Gizzard Shad in a Piedmont Reservoir

The food habits of larval Lepomis spp. and gizzard shad (Dorosoma cepedianum) in Hyco Reservoir, North Carolina, were studied during 1982. Results indicated that Lepomis spp. began feeding at a length of 4 mm on copepod nauplii and the rotifers Polyarthra and Filinia. Selection later (10 mm) shifted to Bosmina, Daphnia, and Mesocyclops, while Diaphanosoma was strongly selected for by all sizes of larvae. The crustaceans Diaptomus, Ceriodaphnia, and Holopedium, along with most rotifers, were not selected.

Possible Effects of Changes in Fishing Regulations on a Black Bass Population in the Kentucky Section of Kentucky Lake

Objectives of this study were to collect information on food, prey availability, and growth rates of black bass (Micropterus spp.) and to determine what type of restrictive harvest regulations would be best for their management in Kentucky Lake, Kentucky. The available fish prey/predator ratio (AP/P) in the Blood River embayment was near 1 : 1 until fish reached 300 mm length, and then available prey biomass increased rapidly. Fish prey were the major food item of all 3 species of bass > 150 mm (largemouth bass, M. salmoides, spotted bass, M. punctulatus, and smallmouth bass, M.

Food And Feeding Of Fish In Hartwell Reservoir Tailwater, Georgia-South Carolina

Food of silver redhorse (Moxostoma anisurum), redbreast sunfish (Lepomis auritus), green sunfish (L. cyanellus), and bluegills (L. macrochirus) was examined to determine whether or not these fish in the Hartwell Reservoir tailwater (Savannah River, Georgia-South Carolina) ate organisms entrained from the reservoir or displaced from the tail water during water releases associated with the production of hydropower. These fish fed primarily on aquatic insects, crayfish, and terrestrial organisms originating from the tail water. Major periods of feeding occurred during nongeneration.
