Evaluation of Largemouth Bass Harvest Regulations For South Dakota Waters
… undertaken at Lake Alvin during 1989; anglers harvested an estimated 15 largemouth bass/hectare that exceeded 380 mm. Thus, the 380-mm length limit was a successful tool for management of largemouth bass in Lake Alvin. In pre-regulation, 1986 electrofishing samples taken from Lake Yankton, …

Modelling to compare harvest regulations in recreational fisheries: case study of smallmouth bass fisheries
… management, including structural indices, catch, harvest, and yield. Eight creel limits (1-8 fish/angler-day) and ten length limits (six minimum limits, three slot limits, and no length limit) were simulated in all possible combinations. A catch-and-release scenario was also simulated, increasing …

Evaluating the effects of angler behavior on the efficacy of harvest regulations in recreational fisheries
… length limits were simulated. Scenarios for no regulations and catch-and-release were also simulated. Angler noncompliance varied from 0% to 50% and voluntary release included rates of 20%, 50%, and 80%. Based on catch, harvest, yield, and PSD, the ranking of specific regulations changed little …

Evaluation of Current Management Strategies for the New River, Virginia, Muskellunge Fishery: Modeling the Effect of Alternative Harvest Regulations and Habitat Selection
… benefits and angler support for more restrictive harvest regulations and to quantify habitat selection at multiple spatial scales. A secondary objective was to develop an alternative procedure for testing differences in muskellunge condition from relative weight Wr data that incorporates …

Recreational specialization as an indicator of attitudes and management preferences of Virginia river anglers
… to catch fish, were satisfied with catching and harvesting smaller fish, and favored liberal harvest regulations. Specialists were more likely to cite resource-oriented motives (testing skills, trophy fishing), to rely on skill to catch fish, preferred to catch and release larger fish, and …

Evaluation of Smallmouth Bass Introductions in South Dakota Lakes
… provide a preliminary assessment of the need for harvest regulations . Stocking efforts were successful in most waters where rock/boulder habitats were available. Dominant year classes in the samples were not entirely dependent upon the stocking of fingerlings. Differences in growth, variability …

Comparison of Creel Survey Data to Traditional Sampling Techniques in Pit-Lake Fisheries of Muhlenberg County, Kentucky
… Changes in population structure due to modified harvest regulations may be responsible for the significant differences (Big Reno and Lime). Population structures were verified with relative weight, length-at-age, and an assessment of five years of largemouth bass and bluegill PSD data. It appears …

Population ecology of wood ducks in Nevada under experimental manipulation of harvest
… populations. I experimentally manipulated harvest regulations for wood ducks in Nevada, to study how harvest affects population level change in abundance and the mortality process. Additionally, I assessed how variation among individuals affects the mortality and recruitment processes. …

Population Dynamics and Spatial Ecology of White-tailed Deer in the Central Appalachian Mountains of Virginia
… in both population vital rates and hunter harvest regulations. In this study, I address each of these concepts within a deer population in Bath County, Virginia, that has presumably been in overall decline since the early 1990's. From June-September, 2019-2020, I monitored survival and …

DNA-based Population Estimation, Harvest Vulnerability, and Home Range Dynamics of Black Bears in Western Maryland
… have rebounded to a point where recreational harvest has now become an important management tool. Having a better understanding of bear population parameters, movements, and harvest vulnerability allows managers to implement hunting more effectively and responsibly. To estimate demographics of …

Behavioral ecology of wild turkeys
… understanding of turkey recess behavior, future harvest regulations in Illinois will be informed by improved knowledge of the partial incubation period and the timing of hen recesses. In Chapter 4, I analyzed 48 nest attempts to evaluate the influence of recess behavior described in Chapter 3, …

Band-Recovery Analysis and Survival Estimates for South Dakota Giant Canada Goose Populations
… of banding region. In addition, effects of harvest regulations on survival of giant Canada geese were analyzed. Data were separated and analyzed for three sample periods (1960-76 considered historical, 1977-86 considered restrictive, and 1987-95 considered liberal) and two regions (Waubay …

An investigation into hunter preference and accuracy of various methods of harvest reporting on public lands in Illinois
A multiple harvest reporting system is used for public land hunters in Illinois. The location, type of species, type of property hunted, and the type of weapon used determine what type of harvest reporting method is required. Currently, Illinois harvest reporting methods include: check-in stations, …
