"An Evaluation Method for Reasonable Stocking of Filter-feeding Fish in Reservoirs" by the Yangtze River Institute of the Chinese Academy of Fishery Sciences was authorized by the National Invention Patent

A few days ago, a "reservoir filter-feeding fish" was invented by the large-water aquaculture post team of the national characteristic freshwater fish industry technology system, a member of the lake and reservoir proliferation fishery innovation team of the Academy of Water Sciences, and associate researcher Li Xuemei of the Yangtze River Fisheries Research Institute of the Chinese Academy of Fishery Sciences.

Large open water bodies such as lakes and reservoirs are not only important water source reserves, but also an important supply base for freshwater aquatic products, especially high-quality aquatic products in China

The invention discloses an evaluation method for reasonable stocking of filter-feeding fish in a reservoir, including sample collection, sample processing and determination, biomass calculation, estimation of natural fish productivity in a reservoir, and evaluation of reasonable stocking amount of filter-feeding fish bighead and silver carp; Based on the plankton, organic debris and other bait biological resources in the reservoir area, the stocking amount of filter-feeding fish can be evaluated by calculating its annual production output, which can protect the water environment and realize the efficient and rational utilization of the reservoir fishery
