This study analyzes the fishing capacity of the multi-species Khanh Hoa’s offshore handline fleet in the context of the World Trade Organization (WTO) agreement on subsidies for fisheries using a sample of 45 fishing vessels (15% of the total population). Based on the data of fishing year-seasons 2015/2016, the results indicate that the fleet’s excess capacity is quite moderate—in the range of 10.77%–24.62% for yellow fin tuna and 15.72%–28.28% for big eye tuna—compared to current catches, if the technical efficiency of the fishing vessels were improved. The partial excess capacity in this fishing fleet is, however, quite considerable— up to 47.83% for yellow fin tuna and 80.62% for big eye tuna. It means that if fishers only target one species and the other outputs remain unchanged, the partial excess capacity of the fleet would be significantly large. Large vessels have higher fuel subsidies than small vessels, but they have lower fishing capacity utilization than the smaller vessels. Larger vessels also overuse fuel, which should, on average, decrease by 13.6% compared to the optimal level. The fuel support policy for this fishing fleet should thus be reconsidered and revised.

This study analyzes the fishing capacity of the multi-species Khanh Hoa’s offshore handline fleet in the context of the World Trade Organization (WTO) agreement on subsidies for fisheries using a sample of 45 fishing vessels (15% of the total population).
