摘要:增殖放流是恢复渔业资源、保护生物多样性、改善水域生态环境和促进渔业资源可持续利用的重要途径,许多国家都开展了大规模的增殖放流活动。但由于对放流技术及后续管理研究不充分,增殖放流工作存在一定的盲目性,导致一些增殖放流效果不明显。为指导科学地开展增殖放流工作,获得更好的增殖放流效果,通过对国内外渔业资源增殖放流相关文献与案例的综合分析,探讨了影响渔业资源增殖放流效果的主要因素,分析了各因素中的关键点和择优应用的措施与经验:确定适宜的苗种放流规格范围及放流数量,选择适宜的放流生境;确保放流的苗种强健无病,采用适宜的苗种运输与放流操作方式;确定适宜的放流时间;加强增殖放流后期的管理,制定科学有效保护措施,保护好放流水域和放流种群等。

Abstract: Stock enhancement is an important way to restore fishery resources, conserve biological diversity, improve water eco-environment and promote sustainable utilization of fishery resources. Stock enhancement activities were widely carried out in many countries,which were not scientific to some extent and effects were not good sometimes due to insufficient study and knowledge on restock enhancement technology and management. To find the scientific and effective way of stock enhancement and guide the work more effectively, the major factors influencing the effects of fishery resources stock enhancement and the key points were discussed based on comprehensive analysis of literatures and practical cases. And good measures or experiences were suggested in this paper, which included: determination of appropriate seed sizes and releasing quantity; selection of suitable habitat condition for releasing; guarantee health of the seed, appropriate transportation used and good operation for seed releasing; determination of appropriate releasing time; reinforcement of stock enhancement successive management, establishment of scientific and effective conservation measures to protect water environment and populations.
