附註: | Bibliography: p. 20 Literature cited. Summary. Seasonal changes in areas fished. Distribution of total fishing effort. Methods. Other charts show the relative intensities in each month of the year. The areas of most intense fishing varied in location from month to month. The relative importance of the Georges Bank grounds varied from a low in April when 63.5 percent of the total fishing effort was spent there, to a high in October when 94.2 percent of the effort was spent on these grounds. One chart shows the relative intensity of fishing over the areas fished for the entire study period. The most important grounds for the United States haddock fishery are on Georges Bank. About 82 percent of the fishing effort over the 12-year period was spent on this bank, the most heavily fished areas being Northern Edge, Southeast Georges, and the "Corner" between South Channel and Georges Bank proper. The remaining 18 percent of fishing effort was spread among the various Nova Scotia banks, particularly Browns Bank, Emerald Bank, Horseshoe Ground, and around Sable Island. This report presents information concerning the areas fished for haddock by the United States otter-trawl fleet over a 12-year period, 1938-49. A series of charts is included. |
