In the earlier years, Georges Bank (ICNAF Subarea 5) supplied most of the landings; but, since 1965, the U.S. fleet has abandoned Georges Bank to the Canadians and concentrated on the Middle At- lantic grounds (ICNAF, Statistical Subarea 6). Incidental Catch Lowered for Yellowfin Tuna BCF has announced that tuna bait boats in the regulated area of the eastern Pacific Ocean are restricted to an incidental catch rate of 15% for yellowfin tuna taken with other tuna--and with bonita, billfishes, and sharks. Bait boats are tuna boats that use hooks and lines. Regulations published in the Federal Reg- ister, May 3, 1969, permitted bait boats fish- ing regulated area during closed season to land yellowfin tuna up to 50% of vessel capac- ity, or 130 tons per vessel, whichever was less, until a total of 1, 500 tons was reached. Also, the regulations provided that when limit was reached, the incidental catch of yellowfin would revert to 15% maximum. An announcement that the 1, 500-ton limit was reached appeared in the June 11 Federal Register. The limitation became effective on June 13. Purse Seining for Winter Industrial Fishery Deemed Impractical Purse seining is not economically feasible for the menhaden industry to catch a winter supply of industrial fish in the mid-Atlantic coastal area. This is a preliminary finding of a study by the Virginia Institut
