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...

A large portion of the 6,000-ha impoundment of the Ouachita River, located within the Felsenthal National Wildlife Refuge, is covered by dense aquatic vegetation. Grass carp are commonly used to control aquatic vegetation in closed systems, but results of stocking grass carp for vegetation control in open systems is less certain. Radio transmitters were implanted in 48 adult triploid grass carp. Grass carp were released in the reservoir during fall 2006. Radio...
