| 摘 要： | 为了恢复浙江渔场大黄鱼资源，1998—2002年，浙江省在浙江北部沿岸海域进行了大黄鱼增殖放流可行性研究。通过5年来的放流试验表明，在浙北沿岸进行大黄鱼放流是完全可行的，放流鱼能够在放流区域附近海域存活、生长，并进行索饵、产卵洄游，同时形成了一定数量的捕捞群体，放流鱼回捕率较高，放流效果较好。文章对试验放流过程中出现的问题进行了探讨和分析，为今后进一步大规模放流提出了建议。

| Abstract: | In order to gradually restore the stock of large yellow croaker Pseudosciaena crocea in Zhejiang fishing ground, an enhancement and release feasibility study was carried out in the north coast of Zhejiang province from 1998 to 2002. The results show that it is absolute feasible to release large yellow croaker in the north coast of Zhejiang province, and the release fish can exist, grow, forage and spawning migration, thus forming an amount of fishing stock. With its recapture rate being high, the activity bears a better result. The problems engendered in the course of releasing were discussed and analysed. The suggestions regarding future large - scale releasing were given. |
