FORTIETH BIENNIAL REPORT 39 The dogfish is taken by trawl nets in the northern part of the State, principally during December and January. As these fish are of the same group that range the coasts of Washington and Oregon, and as Northern California is about the southern limit of their commercial distribution, the effects of the increased otter trawl fishery have not been noticeable on this species. Bottom fish investigations dealing with over 20 commercially impor- tant species were reinaugurated during this biennium. Personnel was assigned to this work, and some start made toward solving the problems necessary for adequate management of this industry. Log book records which, due to personnel shortage had suffered seriously during the war, were obtained ; and the collection of these statistics in the future was out- lined in conjunction with the objectives desired in this fishery. The reopening of the Eureka laboratory at the close of the bienniam, and the assigning of part-time personnel to the collection of biological data will enhance the current analysis of the many species that are included in the scope of these investigations. Graduate students at Stanford Uni- versity, working in cooperation with the bureau, have made valuable contributions to the life-history studies of the sand dab and starry flounder. CRAB The crab fishery of Central and Northern California has undergone tremendous expansion since prewar days. This luxury item is now caught and marketed in mass production quantities. Ten years ago the catch was controlled by a tight organization that kept quantity low and price high. When the Eureka fishery developed to threaten the San Francisco monopoly, and when the more efficient trap or "pot" replaced the old. Figure 17. California crab landings, 1937-38 through 1946-47.
