| 甲壳类作为增殖放流的重要组成部分，可以有效地养护、补充自然海域的渔业资源。文章基于2017—2021年浙江省甲壳类增殖放流数据及相关文献资料，系统梳理了甲壳类放流种类与数量、放流资金等的年间变化趋势及放流海域、放流规格的空间、数量分布，结果显示：浙江省2017—2021年甲壳类增殖物种有日本对虾（Penaeus japonicus）、三疣梭子蟹（Portunus trituberculatus）、中国对虾（Penaeus chinensis）等6个种类，共计放流522 045.5万只，投入资金3 320.2万元，其中放流量、投入资金最多的是日本对虾，放流量最少的是拟穴青蟹，投入资金最少的是葛氏长臂虾，放流区域涉及温州、宁波、台州、舟山等市，各区域间的放流布局不平衡，且主要集中在小、中规格。文章将对浙江近海甲壳类放流物种存在的效果评估工作不足、个别增殖物种放流效果不佳、甲壳类放流储备物种少等问题提出针对性建议，以期为今后完善科学的增殖放流管理提供依据。 |

| Abstract: |
| As an important part of proliferation and discharge, crustaceans can effectively conserve and supplement fishery resources in natural waters. Based on the data of crustacean proliferation and release in Zhejiang Province from 2017 to 2021 and related literature, this paper systematically reviewed the annual variation trend of crustacean release type and quantity, release capital, and the spatial and quantitative distribution of release area and release specifications. The results show that: from 2017 to 2021, six species of crustacean proliferate in Zhejiang Province, including Penaeus japonicus, Portunus trituberculatus and Penaeus chinensis, etc..A total of 5220,455,000 were released, and the investment was 33,202,000 yuan. Among them, the largest amount of release and investment was Japanese prawnaeus, the least amount of release was green crab, and the least amount of investment was Prawnaeus puerarii. The release area involved Wenzhou, Ningbo, Taizhou, Zhoushan and other cities, and the distribution of release was unbalanced between regions, and mainly concentrated in small and medium sizes. In this paper, some specific suggestions will be put forward on problems such as insufficient assessment of the effect of crustacean release species, poor release effect of some proliferating species, and few reserve species of crustacean release in the coastal waters of Zhejiang Province, so as to provide a basis for improving the scientific management of crustacean release species in the future. |
