摘要：Maximum daily consumption and specific daily metabolic demand were determined for juvenile flathead catfish (Pylodictis olivaris) in the laboratory over a temperature range of 3-32 °C. Maximum daily consumption increased with increasing water temperature, was significantly higher at 19 °C than at colder temperatures, and remained elevated up to 32 °C. Fish rarely ate below 15 °C, most stopped feeding at 11 °C, and no fish consumed anything at 7 °C or below. Specific daily metabolic demand showed a gradual increase with increasing temperature. The quantification of consumption and metabolic demand for juvenile flathead catfish was consistent with descriptions classifying the species as adapted to warmwater conditions.
