Method for culturing mature fish of Erythroculter ilishaeformis

Abstract

The invention relates to a method of culturing Erythroculter ilishaeformis adult fishes. The method comprises the following steps: stocking the fish fries of Erythroculter ilishaeformis adult fishes in the water area of 5-10 mu with the density being 800-1000 / mu, and the specification of the fish fry stocking being 15-18 cm; providing a clean pond, rich water, water quality management, and the feeding of fish meals; controlling the water environment and the disease occurrences in the culturing process; and obtaining the Erythroculter ilishaeformis adult fishes with the average weight being 0.50kg / tail after one year of culture. Compared with the other inorganic and organic water fertilizing methods, the invention adopts the fertilizing method of using the zymotechnics of multiplicity of microbe groups, so as to reduce the pollution to the feeding environment of the pond by fertilizer water and achieve the purpose of emission reduction. In addition, photosynthetic bacteria are poured after the second day of the water fertilizing, so as to further increase the content of the photosynthetic bacteria in the pond, thus being favorable to the culturing of food organisms, decreasing thenumber of pathogens, and reducing the occurrence of various diseases.
