Mark-Recapture Creel Survey and Survival Models
… by combining mark-recapture procedures with a creel survey. We also consider the analysis of a proportional hazards survival model for randomly censored observations, known as the Koziol-Green model. The model assumes that the lifetime survivor function is a power of the censored time survivor …

Results and Evaluation of An Aerial Creel Survey Technique On Lake Sharpe, South Dakota
A creel survey, consisting of two independent surveys, was conducted on Lake Sharpe, South Dakota from May, 1973, through May, 1974. An aerial fisherman count was used to estimate fishing pressure and an angler interview survey was used to estimate catch rates, mean party size, mean fisherman day, …

Comparison of Creel Survey Data to Traditional Sampling Techniques in Pit-Lake Fisheries of Muhlenberg County, Kentucky
… (PSD) data can be obtained from a mandatory creel survey. It was hypothesized that the proportion of stock-to-quality (300-400mm) and quality (+400mm) largemouth bass from four years (2007-2010) of creel survey data would be statistically similar to those generated through on-site sampling in …

Comparing estimates of fishing effort and lake choice derived from aerial creel surveys and smartphone application data in Ontario, Canada
… study, I compared results from app and aerial creel survey data from Ontario, Canada. A standard major axis regression found low agreement between effort estimates (n=111, R2=0.20, p=8.2458e-07) and app-based effort was poorly explained by lake characteristics in a random forest analysis (7.66% …

Evaluation of Largemouth Bass Harvest Regulations For South Dakota Waters
… for pre-regulation samples. A random-stratified creel survey was 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 …

The population dynamics of shortnose gar in the Illinois River to inform management of an emerging recreational fishery
… strategy. In my second study, I utilized a creel survey of Illinois bowfishing tournaments to characterize bow angler fishing habits and harvest with an emphasis on gars. Although invasive carp species (Cyprinidae) dominate the harvest composition, gar populations may be vulnerable to …

Characterizing a Hidden Fishery: Setline Fishing in the New River, Virginia
… Virginia by multiple methods, yet standard creel survey approaches do not accurately sample setline effort, a popular fishing gear for catfish. I characterized the New River setline fishery by estimating setline effort and catch rates of catfish and by-catch in 2011, and by investigating the …

Modelling to compare harvest regulations in recreational fisheries: case study of smallmouth bass fisheries
… were fitted for ten sets of complete trip creel survey data from the New and Shenandoah Rivers in Virginia and West Virginia. The fits for eight of ten datasets were not significantly different from the observed distributions (P< 0.05). The negative binomial provides a good alternative when …

An evaluation of harvest, survival, growth, and movement of five strains of rainbow trout (Salmo gairdneri) in Virginia Streams
… of each strain in March and May, respectively. Creel and electrofishing surveys were conducted to determine harvest, movement and survival after fishing. A reference (unfished) stream was also selected and stocked with 50 of each strain, and electrofishing surveys were conducted to determine …

Economic Models of Recreational and Commercial Fishing and Their Impact on the Great Lakes Ecosystem
… PCB-contaminated sportfish. We use 19 years of creel survey data to estimate the effect of more lenient fish consumption advisories (FCAs) on the size of Chinook salmon kept and the effect of more stringent FCAs on the number of yellow perch kept. We find that in both cases the FCAs appear to …

Ecology of Fish Communities in Nebraska Sandhill Lakes
… lakes. I also evaluated angler impact by using creel data and studied populations in three lakes that were closed to fishing. Finally, I used radio telemetry to determine habitat selection of bluegills Lepomis macrochirus in one Sandhill lake. There was little evidence of density-dependent …

Impact of localized harvest on the population of smallmouth bass (Micropterus dolomieu) of Lake Moomaw, Virginia
… bass population were analyzed by means of a creel survey in the headwaters area during the spring spawning seasons of 1995 and 1996. Effort, catch, and harvest, as well as user characteristics and motivations data were obtained from direct interviews with anglers using this area. Estimates …

Recreational use, social and economic characteristics of the Smith River and Philpott Reservoir fisheries, Virginia
I used on-site interviews and angler counts to estimate angler effort, catch and harvest rates, and total catch and total harvest. On the Smith River, angling pressure per km was most intense in the special management area, with most use occurring on weekend days. Anglers harvested approximately …

Angler satisfaction and management preferences in the southern Lake Michigan fishery
… information during the 2015 Lake Michigan creel survey; 422 responded and completed the survey (32.2% return rate). To analyze satisfaction, anglers were divided into three groups: those targeting salmonid species, those targeting yellow perch, and those targeting minor species. Several …

Assessing variability in standardised harvest rates from shore-based recreational fishing surveys
… to analyse catch and effort data from a roving creel survey of shore-based recreational fishers in the Perth metropolitan area to determine the impact of factors (survey year and month, targeting, fishing platform, fishers avidity, time of day and day type) on estimates of harvest rates for key …

Urban Fisheries in Eastern South Dakota: Assessment of Angler Satisfaction and Fishery Resources
… address the first two objectives, we conducted a creel survey over 13 months from April 2009 to October 2010. A total of 718 interviews were completed on five urban fisheries located in Brookings, South Dakota. Angler use of urban fisheries was substantial. Total angler hours was estimated at …

Contribution of Natural Recruitment to the Rainbow Trout Oncorhynchus mykiss Sport Fishery in Deerfield Reservoir

Seasonal Distributions, Movements, and Habitat use of Adult Yellow Perch in a Simple Basin
… if placed in shallow littoral habitats. A fall creel survey would benefit managers responsible for monitoring the yellow perch population in Lake Madison, as the results from this study suggest that a substantial proportion of the total annual harvest may occur during this season.
