Impact of temperature on food intake and growth in juvenile burbot
The effect of temperature on food consumption, food conversion and somatic growth was investigated with juvenile burbot Lota lota (age 0 years). Juvenile burbot showed a significant dome shaped relationship between relative daily food consumption ( C R ) and temperature ( T ) with C R = − 0·00044 T...
