. Commercial fisheries review. Fisheries; Fish trade. 13 BUREAU OF COMMERCIAL FISHERIES PROGRAMS North Pacific Fisheries Explorations and Gear Development "COBB" FINDS NO LARGE HAKE SCHOOLS The "John N.

The primary purpose was to determine the distribution of schools of Pacific hake (Merluccius productus) while the Cobb worked along with the commercial hake vessels. Other objectives were to obtain biological data and more data on the hake's availability to the Cobb pelagic trawl. Echo sounding transects were miade throughout the area surveyed. When suitable tracings appeared on the echogram, they were fished with the Cobb pelagic trawl to deter- mine species composition and abundance. The concentrations then were sounded out to determine their dimensions. This informa- tion was relayed to the commercial boats. No large schools of hake were found. The five tracings observed on the sounder dif- fered from those of previous cruises. They were not as compact nor as concentrated at any one depth. The first was located 18 miles west of Cape Beal, Vancouver Island; the second 25 west northwest of Cape Flat- tery; the third 15 miles west of La Push; the fourth 14 miles west southwest of Destruc- tion Island, and the fifth 12^ miles west of Cape Disappointment. The catches ranged from 2,000 to 15,800 pounds of hake per one- half hour haul; the total length of the hake ranged from 44 to 64 centimeters. Hake signs in the past were quite distinct and re- cognizable as hake, but during this cruise echograms believed to be hake turned out to be only large red jellyfish of the genus Cyanea. This animal usually causes a problem in the otter trawl and salmon trolling fisheries off the Washington coast. The species seemed quite abundant in summer 1966.
