The objectives of the Group were to produce, for each of the stocks of cod, haddock, whiting, plaice and sole:- (a) a historical review of the fishery, and (b) an assessment of the present stage of these stocks with particular reference to the effects of changes in mesh-size and fishing effort. In view of the magnitude of the task and the relatively short time available the Group decide to make mesh-assessments their primary objective and to devote such time as remained to the historical review and to effort assessments.
