Studies were made of the deep water cisco fishery on New York waters of Lake Ontario during the summer and fall of 1942. Experimental gill nets were set to test the 2 3/4 inch mesh, as provided under present New York regulations, against various other mesh sizes to determine if changes in the regulations were advisable in order to increase the production of ciscoes. Conclusions are based on a total catch of 2,393 ciscoes of which 93.23 per cent consisted of a single species, the bloater (Leucichthys hoyi). Characteristics of the different species of ciscoes and fishes associated with them were considered in formulating the recommendations. The catch of bloaters by the nets of each mesh size are analyzed with respect to number of fish taken, average length and weight, sex ratio and condition. Studies on the age and growth of the bloater are presented. A change to 2 1/2 inch mesh was recommended for the deep water ciscoes provided that such nets are not fished in less than 180 feet of water.
