Distribution and feeding of pumpkinseed ('Lepomis gibbosus') and black crappie ('Pomoxis nigromaculatus') in a power plant cooling lake

Technical Report ·
OSTI ID:7302975
The distribution, feeding, movements, and condition of pumpkinseeds (Lepomis gibbosus) and black crappie (Pomoxis nigromaculatus) along the horizontal thermal gradient of Lake Columbia were examined during the autumn of 1975. Distribution and condition data were obtained by capturing fish with fyke nets stratified by temperature. Fish feeding habits were determined by stomach content analysis. Evidence of fish movement was sought by comparing known macroinvertebrate and zooplankton distributions to fish stomach analysis. Results indicate that the fish were not aggregating at their preferred temperature.
