REVIEWS 81 PURSE SEINING FOR PACIFIC ALBACORE California's purse-seine fleet traditionaly has fished for yellowfin, skipjack and bluefin tnna, but shied away from the wary and elusive albaeore. Occasionally, however, albacore {Thunnus germo) have been taken by purse seiners, either as pure schools or when mixed Avith bluefin tuna. During- the nine-year period 1951 through 1959, 19 seiners made incidental catches totaling- 60 tons. The use of nylon webbing- to make larger, lighter, and deeper nets; power blocks that permit fast and efficient retrieves (Figure 1) ; hydraulic and electrically controlled winches of improved design; plus other gear improvements have in- creased the desire among boat owners to seine tuna, and many high-seas tuna clippers have converted to purse-seine gear. The adveni; of the,':e "clipper-seiners" among- the fleet brought about some interesting changes in catch statistics. In 1960, 16 seiners landed over 100 tons of albacore, nearly double the catch of the preceding nine years. One "clipper-seiner" actually sought albacore and accounted for slightly more than 30 percent of the FIGURE 1. Purse seiners with and without power blocks. (Photograph by Harold B. C/emensj.
