This book was released on 1984 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.

This book was released on 1963 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Little information has been published regarding the American plaice, Hippoglossoides platessoides platessoides (Fabricius), a subarctic species which is distributed from Cape Cod to Labrador. In recent years plaice has risen rapidy in commercial importance in eastern Canada. In 1940 only 3 million lb were landed compared to a total of more than 74 million lb in 1960. American plaice in 1961 made up 64 per cent by weight of the total Canadian flounder landings, excluding halibut. [...]" --

Book excerpt: "Landings from the American plaice fishery in the Gulf of St. Lawrence have been stable since 1963. A series of commercial catch and effort data from 1972-1980 is presented using a median smoother. The commercial CPUE however, may not be indicative of trends in the overall fishery since the large vessels of the mobile fleet do not direct their effort on plaice. Data from research vessel surveys indicate that a number of strong year-classes, especially those of 1971 and 1972 are entering the fishery. Biomass estimates for 1980 also indicate that the total plaice biomass has doubled since 1970"--Abstract.
