Abstract: The pole-and-line and live-bait fisheries of the eastern, central, and western Pacific Ocean are reviewed, including landing trends of tunas and catch and effort statistics on the fisheries for the tuna baitfishes. It was estimated that landings of tuna by the live-bait, pole-and-line fisheries contributed about 35 of the total Pacific landings of tunas in 1970. Also included were gross comparisons of the relative effectiveness of the live bait used in the various fisheries and discussions of the factors that may effect the relative effectiveness. The mean catch of tuna in metric tons per metric ton of bait was estimated at 7.5 in the eastern Pacific, 9.8 in the Japanese fishery, and 23.1 in the Hawaiian pole-and-line fishery. Thus, in terms of the catch per unit of bait, the Hawaiian fishery was 3.1 times more efficient than the eastern Pacific fishery and 2.3 times more efficient than the Japanese pole-and-line fishery.
