Relationships Among Catch, Angler Satisfaction, and Fish Assemblage Characteristics of an Urban Small Impoundment Fishery

SEAFWA Journal Volume 4, March 2017

Urban fisheries provide unique angling opportunities for people from traditionally underrepresented demographics. Lake Raleigh is a 38-ha impoundment located on the North Carolina State University campus in Raleigh. Like many urban fisheries, little is known about angler use and satisfaction or how angling catch rate is related to fish availability in Lake Raleigh. We characterized the recreational fishery and fish assemblage with con- current creel and boat electro fishing surveys over the course of one year. In total, 245 anglers were interviewed on 68 survey days. On average, anglers...

Population Characteristics of Flathead Catfish in the Lower Tennessee-Tombigbee Waterway

SEAFWA Journal Volume 2, March 2015

Flathead catfish (Pylodictus olivaris) populations were sampled in three northeastern Mississippi reservoirs (Aberdeen, Columbus, and Aliceville) along the Tennessee-Tombigbee Waterway to evaluate stock characteristics. Specifically, data were collected on relative abundance, growth, mortality, recruitment, and size structure. These samples were part of a statewide effort to document current population status in reservoirs and to develop management goals. Sampling was conducted in late summer (July-August) during 2011-2013 using low-frequency electrofishing. All fish 250 mm total length...

Increasing the Efficiency of Florida&#39s Freshwater Fisheries Long&#45term Monitoring Program

SEAFWA Journal Volume 1, March 2014

In an effort to evaluate the Florida Fish and Wildlife Conservation Commission (FWC)'s long-term fisheries monitoring program for inland water bodies, we conducted a power analysis utilizing fish data from electrofishing, mini-fyke net, and gill net samples. We resampled data and simulated the effects of different combinations of gear and sample size for collecting presence - absence information. Our objective was to determine whether the use of either mini-fyke nets or gill nets could be eliminated or reduced in the monitoring program. Thirty fyke net/gill net gear combinations were...

Diet Composition of Wild Brown Trout and Stocked Rainbow Trout in a Coldwater Tailwater Fishery in North Georgia

SEAFWA Journal Volume 1, March 2014

The Lanier Tailwater section of the Chattahoochee River, Georgia, below Buford Dam has populations of wild brown trout (Salmo trutta) and stocked rainbow trout (Oncorhynchus mykiss). To better understand the ability of wild brown trout to recruit to the fishery, stomach contents of brown trout and rainbow trout were examined in summer and fall 2011 and winter and spring 2012 at four locations along the river. Midges (Diptera) were the most common category observed in the diets of both species throughout the study. Other common items included caddisflies (Trichoptera), stoneflies (...
