| 摘要: |
| 20世纪80年代以来，浙江近海的主要渔业资源呈现衰退趋势，因此从2000年至今相关单位持续开展人工增殖放流以修复渔业资源。文章基于2017—2021年浙江近海鱼类增殖放流统计数据作出分析，对比放流资金、放流数量、放流物种等变化趋势得出：2017—2021年主要在浙江近海12处重要的增殖放流海域投放了大黄鱼（Larimichthys crocea）、黑鲷（Acanthopagrus schlegelii）、黄姑鱼（Nibea albiflora）、条石鲷（Oplegnathus fasciatus）等16种海洋鱼类，累计投入放流资金11 285.9万元，投放海洋鱼类苗种共计46 799.8万尾，其中标志鱼投入共330.1万元，放流苗种48.8万尾。调查和文献报道显示，增殖放流对增加浙江近海海洋鱼类生物资源量、恢复海洋鱼类群落结构、保护海洋生物多样性，促进海洋渔业的发展等方面起到积极的作用。根据调研情况和相关文献梳理了增殖放流存在的问题并提出了相关的改进建议，以期为今后科学规范实施增殖放流提供参考。 |

| Abstract: |
| Since the 1980s, the main fishery resources in Zhejiang offshore have shown a declining trend. Therefore, since 2000, relevant units have continued to carry out artificial proliferation and release to repair fishery resources. Based on the statistical data of proliferation and release of Zhejiang offshore fish from 2017 to 2021, this paper compared the trends of release funds, release quantity and release species. It was concluded that 16 kinds of marine fish such as Larimichthys crocea, Acanthopagrus schlegelii, Nibea albiflora and Oplegnathus fasciatus were mainly released in 12 important proliferation and release sea areas of Zhejiang offshore from 2017 to 2021. The total investment in releasing funds was 112.859 million yuan, and a total of 467.998 million marine fish fry were released, of which 3.301 million yuan were marked fish and 488,000 fry were released. Investigation and literature reports show that stock enhancement plays a positive role in increasing the biological resources of marine fish in Zhejiang offshore, restoring the community structure of marine fish, protecting marine biodiversity, and promoting the development of marine fishery. Finally, according to the investigation and related literature, the author sorted out the problems existing in the proliferation and release and put forward relevant suggestions for improvement, in order to provide reference for the future scientific and standardized implementation of proliferation and release. |
