摘要：

Field experiments were conducted to determine food-evacuation rate and measure stomach fullness. A combination of these data gave estimates of daily food intake of fish. Fish were captured and held in large holding pens and periodically subsampled. Stomach-evacuation rates obtained in this way increased significantly with water temperature over the range 10-25°C, but variation in stomach-evacuation rate was considerable, reducing the utility of water temperature as a predictor of stomach-evacuation rate. -from Author
