Includes bibliographical references (page 11). "American plaice in the southern Gulf of St. Lawrence were found to be in a relatively stable state over the past several years. A changing pattern of discarding at sea was found and this has eroded further the confidence of the commercial catch sampling data. These data are normally used in the preparation of the annual catch-at-age matrix. Without these data no analytical assessment is possible. Possible reasons for the changing discard pattern include changes in minimum mesh size regulations, changes in abundance of the Gulf cod stock, changes in the prices paid for plaice with regards prices paid for cod, and changes in gear composition of the fishing fleet"--Abstract.
