The portion of the Canadian landings below the horizontal line in each bar shows the amoiuit that was exported to the United States in that year. The Fishing Grounds The sea scallop grounds extend from the Gulf of St. Lawrence south to the waters off the Virginia Capes (fig. 2). U. S. vessels have never fished the northern grounds and, until 1965, Canadian vessels had never fished the southern grounds. These northern (ICNAF Subarea 4) and southern (ICNAF Subarea 6) grounds have a history of providing only a small fraction of the total landings. During the years 1945-64, about 80 percent of the landings came from Georges Bank (ICNAF Subarea 5), Abundance One should not regard Subarea 4 and Sub- area 6 during the years before 1965 as con- taining large unexploited stocks of sea scal- lops. Both areas have extremely active ot- ter trawl fisheries, and any news of good con- centrations of sea scallops noticed by these vessels soon reaches the scallop fishermen. In addition, occasional surveys have been made by research vessels in Subarea 4 by Canada, and in Subarea 6 by the U. Fig. 2 - Chart of the ICNAF Subareas along the range of the sea scallop. These investigations, as well as the analy- sis of the commercial landings from these areas, have all shown the same general situ- ation. Wherever concentrations of sea scal- lops were found, they were less dense and covered a smaller area than those on Georges Bank and, almost invariably, they were com- posed of scallops of a single year class. The consensus has been that these grounds re- ceived only occasional spat fall and were of low productivity compared with the Georges Bank grounds. The average annual landings per day spent on the fishing grounds (L/E) shown in table is not a good measure of a
