南海北部湾2012年捕捞产量估算

南海北部湾是广西、广东和海南三省区渔民的传统重要渔场之一，准确掌握北部湾捕捞产量对于搞好北部湾渔业生产管理意义重大。文章采用2012年南海捕捞信息动态采集网络的广西渔船生产数据，参考广西相关渔业调查资料，分别推算2012年广西拖网、围网、刺网、钓具、定置网和其他杂渔具在北部湾的捕捞产量，统计广西全年在北部湾的捕捞产量为39．2×10^4t，进而推算中国渔船2012年在北部湾的产量为65．7×10^4t。在此基础上，再采用相关文献中有关越南渔船在北部湾的产量，估算2012年北部湾的捕捞产量约为85．7×10^4t。

Evaluation of catch in Beibu Gulf of South China Sea in 2012

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 Sys- tem 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.
