BRISTOL BAY AND ALASKA PENINSULA SALMON STATISTICS 89 NICHOLASKI SPIT This particular locality has been fished only since 1924, when a trap was driven here. This trap has caught an unusually large number of red salmon, and Doctor Gilbert has stated, on the basis of scale studies, that these reds apparently were Bristol Bay fish (in part, at least) that were intercepted here as at Ikatan, Morzhovoi Bay, and Unga Island. A tagging experiment planned for the coming summer (1928) undoubtedly will settle this pomt, but it is interesting to note that our catch data lend considerable support to the theory even though only four years are availa- ble for study. If the catches of red salmon from 1924 to 1927 at Nicholaski be com- pared with the catches for the same years at Ikatan, it will be seen that, based on the size of the catch, the rank of each year is identical in the two localities. The largest catch was made in 1926, then came 1924, 1927, and 1925. While such a "rank" method of determining correlation is not especially reliable, particularly. Flo. 17.—Catch of pinks, chums, cohos, and kings at Morzhovoi Bay with so few data, in this case it is so marked as to lend considerable weight to the theory advanced by Doctor Gilbert. The data are too few to warrant any discussion of the other species. PAVLOF BAT The fishery in Pavlof Bay has been conducted with some intensity since 1918 (with the exception of 1921), when traps were first installed. The yield of red salmon has never been consistently large, although in 1918 the catch was over 30,000 and in 1926 exceeded 43,000. The catch of kings has been negligible and that of cohos has been very irregular and never large. The chief species taken in Pavlof Bay have been pinks and chums, and of these the catch of pinks has been by far the more impor- tant; but both species have shown such wide fluctuations t
