Fisheries -- United States; Fish-culture -- United States. s >< ^ tj Vj A /. /Jed sa 41 taken in the Port MoUer fishery are produced mainly in two small riversâthe Bear and the Sandy, a few miles east of Port MoUer proper. Gilbert and O'Malley gave cogent reasons for believing this to be the case, in spite of the opinion held by some that the Port MoUer fishery drew upon the Bristol Bay runs to a greater or less extent. It was believed by some of the men m the industry that in certain years, if not in all, the salmon boimd for Bristol Bay approached the coast in the region of Port Moller and thus were taken in the fishery at that point. The tagging experi- ments carried out in 1922 and 1925 '^ proved conclusively that this was not true, and that the red salmon taken in this region did not belong in any appre- ciable measure to the Bristol Bay runs. Addi- tional evidence of the independence of the Port Moller runs is given by a comparison of the data presented in Table 6 with those for Bristol Bay. It is obvious from such a comparison that there is no significant correlation between the fluctuations in the catches in the two regions, as would be ex- pected if they drew to any great extent upon the same body of fish. These additional lines of evidence, therefore, sup- port the conclusion of Gilbert and O'Malley that the red-salmon fishery at Port Moller is dependent primarily upon the runs supported by the Bear and Sandy Eivers, and we can have no doubt that these are very seriously depleted. The very limited supply has been greatly overexploited, and it seems probable that the process of depletion is continuing even with the reduced intensity of fishing that now prevails. Even under present conditions the intensity of fishing is high, as is shown by the fact that, m the tagging experiments of 1925, per cent of the tagged fish were recovered.
