A curvilinear regression model was used to determine an expected stomach capacity for any size Bear Lake sculpin with a standard length between 4-9.5 centimeters. Stomach contents were then expressed as a percent fullness and the change in percent fullness with time intervals was used to compute an instantaneous digestion rate. The instantaneous consumption rate was computed by the formula C=log P1 - log P0 +d, where C = instantaneous consumption rate. The amount of food consumed during a time interval was computed from the formula It=CtSt, where It=amount of …
