摘要
由于海洋环境污染及过度捕捞造成渔业资源不断衰退,人工增殖放流已成为修复水生生物资源的重要途径.在保护濒危物种、恢复渔业资源的同时,人工增殖放流可提高渔业产量和质量,对修复海洋生态环境具有重要意义.增殖放流策略主要包括放流地点、时间、规格以及方式四个方面,是针对放流幼体在放流中或放流后死亡率较高这-难题采取的相应措施,对放流苗种的存活率及流散率有很大影响.本文从增殖放流的发展现状入手,对国内外增殖放流策略进展做出概述,并探讨了放流方式中存在的问题,以期为今后增殖放流技术的改进提供科学的参考依据.
With the decline of fishery resources causing by marine environ-mental pollution and overfishing, stock enhancement has become an important and effective solution for the restoration of aquatic living resources in traditional fishery. It is important for the recovery of fishery resources and the improvement of fishery production and quality. The strategy of marine fishery stock enhance-ment includes the following four aspects ： releasing sites, releasing time, releasing size, releasing methods. The releasing strategy is one of the crucial factor which affect stock enhancement efficiency, especially the survival rate and dispersion rate of released species. This paper summarizes the current status and analyses the main releasing strategies and explores the present problems in order to provide useful information for the future works.
