Groundfish stock assessments for the west coast of Canada in 1993 and recommended yield options for 1994 / by M. Stocker (editor).: Fs97-6/1975E-PDF

"Groundfish stock assessments for the west coast of Canada, for 1993, and yield recommendations for 1994 are presented. Assessments have been conducted for the following species: lingcod, Pacific cod, petrale sole, Dover sole, rock sole, English sole, arrowtooth flounder, sablefish, Pacific hake, spiny dogfish, walleye pollock, Pacific ocean perch, yellowmouth rockfish, rougheye rockfish, redstripe rockfish, widow rockfish, silvergray rockfish, yellowtail rockfish, canary rockfish, quillback rockfish, copper rockfish, and yelloweye rockfish. A number of analytical methods have been employed in these assessments, e.g., surplus production analysis, virtual population analysis, several variants of sequential age-structured analyses, dynamic pool models, and depletion estimators. Biological objectives are the only considerations of these assessments and yield options. Yield options and recommendations on catch limitations and other management measures to achieve biological objectives are made to the fishery managers of Offshore Division of Fisheries Branch (Pacific Region). Alternative options allow managers to consider high risk and low risk yields in relation to a stock's potential productivity"--Abstract, page iv.
