浙江省淡水渔业增养殖放流现状

为了探明我国境内浙江省内的淡水养殖鱼增养殖放流的现状。研究团队收集并整理了浙江省境内历年淡水渔业增养殖放流数据、淡水渔业增养殖放流技术文献等相关资料。从浙江省淡水渔业增养殖放流的历史、内容、技术以及目的等四方面来阐述其理论背景及其意义。通过讨论浙江省历年淡水渔业资源量的变化、淡水渔业优势种的变化、历年研究人员探明的淡水渔业资源野外调查及境内淡水渔业增养殖放流方案等问题。得出浙江省内渔业增养殖放流人员除仍持续进行淡水鱼类人工增养殖放流工作之外,还应同时加强对于自然水域内的种群监测,及时评估放流效果,避免放流效果不佳等结论。并希以其为水产从业者以及研究人员提供理论数据支持以及技术参考。

Current Situation of Increasing Farming and Discharge of Freshwater Fisheries in Zhejiang Province

In order to find out the current situation of freshwater fish culture in Zhejiang province. The research team collected and sorted out the data of freshwater fishery breeding and releasing in Zhejiang Province over the years, the technical literature of freshwater fishery breeding and releasing, and other related data. This paper expounds its theoretical background and significance from four aspects : the history, content, technology and purpose of freshwater fishery aquaculture in Zhejiang Province. By discussing the changes of freshwater fishery resources, the changes of dominant species of freshwater fishery, the field investigation of freshwater fishery resources proved by researchers over the years and the scheme of increasing aquaculture and releasing of freshwater fishery in Zhejiang Province. It is concluded that in addition to the continuous artificial breeding and release of freshwater fish in Zhejiang Province, the personnel of fishery breeding and release should also strengthen the population monitoring in natural waters at the same time, timely evaluate the release effect, and avoid poor release effect. It is hoped to provide theoretical data support and technical reference for aquatic practitioners and researchers.
