Integration of CPUE data into assessments using the generalised yield model

For the last 3 years, WG-FSA has accorded high priority to development of a method to integrate different indicators of stock status into assessments using the generalised yield model (GYM). In this paper, we propose a method, based on use of the sampling/importance-resampling algorithm, for incorporating information on trends in standardised CPUEs into GYM assessments. The use of the method is illustrated using data for D. eleginoides in Subarea 48.3. As the method requires only very small adjustments to the computer program implementing the GYM assessments, we propose that this method should be adopted for use during the 2000 meeting of WG-FSA.
