中文摘要：为了解深圳市2007年伏季休渔海洋渔业资源的动态变化规律,寻找恢复渔业资源的有效途径,合理开发利用海洋渔业资源,2007年5月和8月在深圳海域利用双拖网、掺缯网和拖虾网等3种渔具进行了渔业资源调查,对渔获结果进行了对比分析。调查结果表明,休渔前后,在珠江口海域掺缯网作业的总渔获量增加了10.8倍,桁杆拖虾网作业的总渔获量增加了5.6倍,但在大鹏湾海域双拖网作业的总渔获量仅为休渔前的72.7%。

外文摘要：A scientific survey of fishery resources in Shenzhen sea area was carried out in May and August of 2007 to evaluate the dynamic change in fishery resources in Shenzhen sea area during the closed fishing season and the effective ways to restore and exploit marine fishery resources reasonably by three kinds of fishing vessels including paired trawl, surface bean trawl and shrimp trawl. The analysis of catches during the investigation showed that the fish output was as high as 10.8 times by the beam trawl, and 5.6 times by the shrimp trawl after the closed fishing season as that before the closed fishing season in the estuary of Zhujiang River, respectively. However, the corresponding fish output by the double trawl in the Dapeng gulf accounted for only 72.7% of the catch before the closed fishing season.
