About 1200 tons of tuna and skipjack were caught by three types of fishing gear mentioned above in Amami area. Tuna and skipjack fishery in this area much depend on FADs (Fish Aggregating Devices). On the other hand FADs (Fish Aggregating Devices) has many problems. Those are accident of rost out that happened less than 10 years of planning period, fisheries adjustment for an illegal fishery by non-registration fishing vessels and the difficulty of estimating of fish aggregating effect of it.
