Última Synthesis on moored FADs in the North West Pacific region ArchiMer Kakuma, S. In early 1980s, fad fisheries were introduced from the Philippines to Japan, mainly to Okinawa. The fisheries have well developed becoming one of the main fisheries in Okinawa where 210 fads are approved to deploy in 1999. The annual catch by roughly 1 000 boats (most of them are small) is 2500-4000 mt; average catch from one fad is about 20 mt; average catch by one boat on one day is 73 kilogrammes. fads are also important for easing the fishing pressures on bottom fish stocks. Most of the fads were deployed and managed by local fishermen's groups that have improved the structures of the system to withstand typhoons. The catches are strongly depending on the sites, usually the farther offshore, the better the catches. A variety of fishing methods are...

Yellowfin tuna (Thunnus albacares) is a main target for the fisheries at Fish Aggregating Devices (FADs) off the south of Okinawa island. Catch and weight composition of the tuna were monitored at a fisheries cooperative market from 1989 to 1998. Some distinct weight groups (considered to represent cohorts) appeared in the catch and the weight of these groups increased monthly - presumably as individual tuna grew. Although small, light weight fish were caught year-round, the 2 kg weight group that was recruited in May grew to about 15 kg by May of the next year. There was a significant seasonal cycle in the monthly catches. The catch of heavier weight groups decreased in winter indicating the tuna moved out of this FAD area. At one of huge FADs (Nirai),...
