浙江省淡水鱼类增殖放流研究进展

Research Progress on Proliferation and Releasing of Freshwater Fish in Zhejiang Province

本文收集并整理了浙江省历年淡水鱼类养殖放流数据、放流技术以及相关文献,阐述了浙江省淡水鱼类增殖放流理论基础、政策保障和发展历程,分析了增殖放流中存在的问题,包括放流鱼类应激反应、无计划放流对生态平衡的影响和放流鱼苗规格对渔业资源的影响。最后得出结论:浙江省淡水渔业增殖放流人员除仍持续进行增殖放流工作之外,还应加强自然水域种群监测,及时评估放流效果,避免放流效果不佳等。

This paper collected and organized releasing data,releasing technologies of freshwater fish in Zhejiang Province,and related literature over the years,elaborated the theoretical basis,policy guarantees,and development process of freshwater fish proliferation and releasing in Zhejiang Province,and analyzed the problems in proliferation and releasing,including the stress response of released fish,the impact of unplanned releasing on ecological balance,and the impact of releasing fish fry specifications on fishery resources.Finally,the conclusion was drawn that in addition to continuing the proliferation and releasing work,freshwater fish proliferation and releasing personnel in Zhejiang Province should also strengthen population monitoring in natural waters,timely evaluate the releasing effect,and avoid poor releasing effects.
