Observations on the Food Habits of the Flathead and Blue Catfish in Alabama

In the Tombigbee, Alabama, and Tensaw Rivers, 34 flathead catfish (Pylodictis olivaris) and 152 blue catfish (lctalurus furcutus) were collected by use of telephone-magneto shockers for stomach analysis. Transition in feeding habits from invertebrates to major use of fish occurred in flathead catfish at approximately 10 inches total length, and in blue catfish through the inch groups 8-13. Feeding habits in the three rivers are compared. Data on lengths of catfish and foods eaten are presented.
