Abstract
Nitrogen excretion rates were measured for bluegill sunfish (Lepomis macrochirus) starved for periods of 7, 14, 21, and 28 days, and for glucose‐fed controls. The starved fish had lower nitrogen excretion rates than controls, but there was no significant difference between average nitrogen excretion rates of starved fish from the four experimental periods. Body composition was analyzed. Protein and fat content decreased with starvation but ash content remained unchanged when compared to controls. The caloric requirement for starved bluegills was calculated on the basis of the change in organic composition of the body.This publication has 0 references indexed in Scilit:
