Abstract
Growth rates of rainbow trout have been calculated and compared for 27 British Columbia lakes. The use of absolute age as a reference point is unsatisfactory in many cases where comparisons involve fish of the same age but of dissimilar sizes. Changes in metabolic efficiency may be primarily a function of size and not of age. An alternative method is suggested, which relates growth rate to size independent of age. Examples are offered of the use of size—specific average instantaneous growth rates.This publication has 0 references indexed in Scilit:
