INTERNATIONAL FISHERIES SURVEY CONTINUES OFF WEST COAST The Soviet research vessel 'Ogon' left San Pedro, Calif., on March 13 to continue an international fisheries survey of the popula- tion of Pacific halce off Oregon and Washing- ton. The vessel is operated by the Far East- ern Seas Fisheries Research Institute in Vladivostok. Dr. Alan R. Longhurst, director of the BCF laboratory at La Jolla, reported that Ogon had just completed an egg-and-larva survey of spawning hake off California and Mexico with the assistance and advice of fishery biologists. The Pacific hake spawns off California and Mexico each winter. The abundance of adult hake is estimated from the number of their eggs and larvae taken in plankton samples. 2nd Year of Cooperation This is the second year of cooperative re- search on hake fisheries. The hake is a favorite food of Soviet citizens. It is fished heavily by the Soviet fleet in international waters off the Pacific Coast; in the , hake is an important raw material in producing fish protein concentrate (FPC). The data from the cooperative surveys are necessary to pro- vide a scientific basis for agreements to pro- tect and conserve the species off North Amer- ica. San Francisco to Vancouver Island Ogon is under the scientific leadership of Dr. Nikolai S. Fadeev of Vladivostok. The Soviet vessel rendezvoused on March 18 with a Coast Guard cutter to take aboard an observer, Eugenes. Maltzeff of BCF's Seattle laboratory. With him ab o a r d, Ogon began usin2 her acoustic echo-sounders to survey hake and rockfish stocks from San Francisco to Vancouver Island. The survey will end at the island by the end of May. The vessel will fish only to check the results of the acoustic survey. Already, BCF scientists at La Jolla are working on samples and data from Ogon's plankton survey. They have found that hake, in response to warm ocean conditions, have spawned this year considera
