Evaluation of Fishery Resource Enhancement by Artificial Propagation and Release in the Silin Hydropower Station Reservoir
摘要
Abstract
Fish artificial propagation and release is an important measure for reducing the impact of hydropower construction on fish resources.Fish population data obtained by tagging the released fish is used to evaluate the ef-fectiveness of the method.The Silin and Shatuo Hydropower Stations are the eighth and ninth cascaded hydropower stations on the Wujing River.The Silin and Shatuo fish breeding and release station was built and began operations in 2009 with the yearly release of 570000 artificially bred native species.In this study, the release and recapture investigation of tagged Barbodes sinensis and Varicorhinus simus was conducted in the Silin hydropower station reser-voir from 2013 to 2015 to evaluate and optimize the fish breeding and release program.In 2013 and 2014, a total of 1.98 ×104 Barbodes sinensis and 4.56 ×104 Varicorhinus simus individuals were tagged and released into Silin reservoir area, and from July to September of 2014 and 2015, fishery resource investigations were carried out using fish catch surveys.A total of 2867 individuals representing 12 fish species were collected during the two-year in-vestigation and B.sinensis (43 individuals) and V.simus (19 individuals) accounted, respectively, for 1.60%and 0.71%of the total catch and no tagged fishes were collected.Based on interviews with fishermen, 14 fish with evident fluorescent tags were caught, giving recapture rates of 0.013%-0.049% and 0.009%-0.030%, re-spectively.All 14 of the tagged fish were caught at seven sites, between 226 to 24105 m from the release site.The sites are all located in shallow water areas of reservoir bays and tributaries, indicating that the tagged fish had a wide range of activity and preferred this habitat.The study shows that artificial propagation and release has a posi-tive effect on B.sinensis and V.simus resources in the reservoir areas of the Silin and Shatuo Hydropower Stations. To enhance the release effect, we suggest improving the tagging method, adjusting the method and location of re-lease, and strengthening fishery management and public education.关键词
