摘要

During 1986-2006, fisheries in Tonkin Gulf had made rapid development. Total engine power increased 11.6 times while total catch only increased 2.9 times. Big increase in number of fishing boats has resulted to the overexploitation in near shore waters since 1995 and this situation has been spread out all over the Gulf now. This paper give detail description of the current status of fisheries in Tonkin Gulf, dynamic trend in number of boats, catches, resources; and discuss relating issues such as capital, economic efficiency of key fisheries in Tonkin Gulf like trawl, purse seine, line fishery and others. In addition to that, fishery management issues toward sustainable development are also analyzed in deep. Analysis, evaluations on marine capture fisheries in Tonkin Gulf have been done with bio-economy model have been made. The study figures out the fact of over-fishing on the resources and the excess of fishing capacity in Tonkin Gulf.
