Intra-season Variation in Largemouth Bass Electrofishing Catch-Per-Unit-Effort: Implications for Management Decisions

The objective of this study was to determine if largemouth bass (Micropterus salmoides) electrofishing catch-per-unit-effort (CPUE) varied within the traditional spring sampling season. Shoreline electrofishing for largemouth bass was conducted on Chowan River and Sutton Lake in 1990 and on Tuckertown Reservoir in 1989 and 1990. There were at least 6 sample stations per body of water. Each of the 3 study locations was sampled 3 times from March through June. The number of bass >200 mm captured and effort were recorded by sample station and date. Effort was measured in electroshock time...

Incidence and Seasonal Variations of Epistylis Among Fishes in North Carolina Reservoirs

Epistylis infections were found on 16 fish species in the Yadkin and Catawba River reservoirs in North Carolina during 1974-75. Families most affected were Ictaluridae, Percichthyidae, and Centrarchidae. Highest incidence of the disease occurred during the summer and fall months. The most common infection site among most species of fishes was inside the mouth. A positive correlation was found between total fish length and Epistylis infection rate among Lepomis auritus, Lepomis macrochirus, and Micropterus salmoides. The bacterium, Aeromonas hydrophila, often was isolated from...
