Food habits of channel catfish in a reservoir receiving heated waters

The diet of channel catfish captured near the mouth of a channel carrying heated waters was not significantly different from the diet of catfish captured elsewhere in the same reservoir during the cool months of the year. In summer months, however, the diet of catfish captured near the effluent was significantly different from the diet of catfish from other locations and seemed to indicate that catfish were foraging in cool, deeper waters beneath the thermal plume.Department of Biological Sciences, North Texas State UniversityFinancial support for the study was provided by a Faculty Research Grant at North Texas State University.
