Abstract: Beibu Gulf has been a traditional and important fishing ground for fishermen from Guangxi, Guangdong and Hainan; therefore, it is significant to evaluate the catch for fishery management and sustainable development in Beibu Gulf. Based on Collecting System of Fishery Information from South China Sea in 2012 and related data and research of catch in Guangxi, we reckoned the catch of various fishing instruments of Guangxi, including trawling, purse seine, gill net, hooking, set net, etc. Then we estimated that catch of Guangxi Province in Beibu Gulf in 2012 is about 392 000 tons, and that catch of China in Beibu Gulf is about 657 000 tons.Adding relative record catch of Vietnam in Beibu Gulf, we estimated the total catch, which is 857 000 tons.
