Abstract: Based on the investigation data of fishing production in the coastal waters of Fujian in 2000 and 2002,eight fishers with varied power vessels have been studied in comparison. The study using DEA method and 2 output factors, which are actual catch value of input factors，and technology fund etc. to calculate their fishing integrative capacity. The results showed that the capacity utilization of different power vessels of 8 fishers varied from 58.4% to 100% with an average value of 85.7%, among them, the capacity utilization of set net, pot funnel, single trawler, drift gill net and light-purse seine with giving invested factors is higher, hook and line and pair trawler is second, and shrimp beam trawl is lowest. The nodeflection capacity utilization varied from 36.9% to 100% with an average value of 71.8%, among them, its of light-purse seine, set net and hook and line is higher, drift gill net and single trawler is second, beam-shrimp net and pot fishing is lower, and pair trawler is lowest. If the equipment situation don't change, the fishing capacity of single trawler, pot and set net is finite improved which depends on strengthening management, however its of beam-shrimp net, drift gill net, lightpurse seine, hook and line and pair trawler obtain a different extent improvement. Alterable input can restrict fishing integrative capacity of different fishery to exert, and influence of immutable input is relative lesser. Now, the potential integrative capacity of fishing vessel less than 220 kW and the vessel of pair trawler and lightpurse seine less than 300 kW is larger and must become main adjusted object of fishing structure. Aggregative degree of DMU is higher that capacity utilization calculating by using of DEA increases, otherwise the capacity catch and value decrease.
