摘要
渔业资源增殖放流是指对野生鱼、虾、蟹和贝类等进行人工繁殖、养殖或捕捞天然苗种在人工条件下培育后,释放到渔业资源出现衰退的天然水域中,使其自然种群得以恢复的一种方法。增殖放流的目的在于保护濒危物种、增加渔业资源产量和修复生态环境,还具有培养渔民环保意识和增加渔民收入等多方面的重要意义。本文从苗种来源、标记方法、放流策略和效果评价四个方面总结了国内外增殖放流的技术,以期为今后的放流工作提供借鉴和参考。
The Stock Enhancement program uses applied research to develop the technology for relea-sing of cultured juveniles to overcome recruitment limitation. The goal of stock enhancement researchis to develop a responsible and effective marine stock enhancement technology (1) to help restore de-pleted populations in the sea, (2) to augment fishery yields, and (3) to restore the ecological environ-ment. Meanwhile, it can also culture the environmental awareness of fishermen and increase the in-come of them. Four main factors are summarized in this paper, including seedling, mark type, strate-gy of release and effect evaluation, with this we can provide reference for later stock enhancement.
