182 CALIFORNIA FISH AND CAME boats north to the relatively shallow (less than 50 fm) area south of East Point on Santa Rosa Island. As the fish were wild and not catchable during the day, the boats, assisted by the spotter aircraft, set at night on visible trails caused by movement of the fish through bioluminescent plankton. The nets of most vessels in the fleet normally fish at 45-50 fm maximum depth, and unless the schools were in shallower water, the fish usually escaped underneath or otherwise evaded the net. Sets were made in water as shallow as 18 fm and as deep as 100 fm. Catches of the large fish were first made on 31 October and continued sporadically through December with the last catch occurring on 3 January 1989. Most of the sightings were made between Santa Rosa Island and Begg Rock. r' ' I I ' I ' ' I I '

FIGURE 1. Areas of catches (crosshatched) of large bluefin tuna captured during November and December 1988. Schools such as these are conspicuous during both night and day when near the surface, and with the aid of fairly constant spotter aircraft activity in previous years, were seen sporadically in 1986 and 1987, although less frequently than in 1988. Schools were reported from the Sixtymile Bank northwest to the Rodriguez Seamount but few, if any, were caught. Prior to this season (1988), spotter aircraft may have ignored large fish in small schools (1-5 fish) because they were either misidentified as pods of marine mammals or judged unprof- itable in tonnage. As prices rose dramatically due to interest shown by Japanese buyers, the spotters and vessels alsobecame interested in the small schools of larger fish.
