Size Structure, Age, Growth, and Mortality of Flathead Catfish in the Robert C. Byrd Pool of the Ohio and Kanawha Rivers
SEAFWA Journal Volume 10, March 2023
Flathead catfish (Pylodictis olivaris) were sampled in the Robert C. Byrd Pool of the Ohio and Kanawha rivers, West Virginia, to inform management decisions based on population characteristics of size structure, age, growth, and mortality. Sampling was conducted with low-frequency boat electrofishing during late May to early June over a four-year period (2017–2020). We examined size structure using proportional size distribution indi- ces. Growth was evaluated using otolith-derived ages, a von Bertalanffy growth curve, and mean length at age data, including comparisons to...
