Abstract
Gulland's method for fitting the Schaefer model is examined using data from 19 groundfish stocks. The relationship between catch per unit effort and averaged effort may arise from statistical artifacts due to the method itself or from the way the fisheries develop. The prevalence of these artifacts in the actual data suggest that this method cannot be statistically justified.Key words: catch/effort data, surplus production model, Schaefer modelThis publication has 1 reference indexed in Scilit:
