Detailed SR Function Description
Food conversion ratio (weight gained by fish/weight of food consumed) for frequently fed age-0 coho salmon in relation to dissolved oxygen concentration. A food conversion ratio of zero (not a negative ratio) has been assigned to each group of fish that lost weight. fitted
Function Type
continuous
Stressor Scale
linear
