Progressing to a scientifically-based assessment and management system for renewed commercial pink and spiny scallop fisheries off the British Columbia Coast
By Lauzier, R.B., L.C. Walthers, W. Hajas, J. Lessard, E. Wylie
Abstract
This document reviews the experimental pink and spiny dive and trawl scallop fisheries of for 2 years in British Columbia waters. Biological data collected during the surveys and experimental fisheries show each species has different growth characteristics, and there are reduced growth rates in northern in comparison to southern waters. Survey methods were developed for each fishery, and the results of surveys are presented. The results of the experimental fisheries are presented and compared to the recommended harvest options. Natural mortality rates have been revised, resulting in a revision of recommended harvest rates. Issues of concern raised during the initial review on abundance and distribution of scallop stocks, sustainability and viability of the trawl fishery, assessment of fishing characteristics of the scallop trawl, localized depletions have been addressed. Assessment and management options have been made on progressing to limited commercial fisheries. Recommendations are made on assessment programs and management measures for limited commercial fisheries.
