Stock Characteristics and Habitat Use of Catfishes in Regulated Sections of 4 Alabama Rivers
We sampled 3 species of catfish (blue catfish Ictalurus furcatus, channel catfish I. punctatus, and flathead catfish Pylodictis olivaris) from 3 different habitat types (tailrace, main channel, tributary) in 4 river systems in Alabama to quantify their relative distribution, age structure, growth, and habitat use. Blue and flathead catfish were more abundant than channel catfish in all systems, and flathead catfish were both most numerous and had the greatest average length in 3 of the 4 systems. Blue and flathead catfish had similar age distributions containing both juveniles and adults,...
