Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a herring feed capable of effectively inhibiting harmful bacteria and a preparation method thereof. Background technique [0002] Herring is a fish with a green color, mainly distributed in the plains south of the Yangtze River in my country, and relatively rare in the north of the Yangtze River; it is an important fishery resource in the middle and lower reaches of the Yangtze River and lakes along the river and the main breeding object in lakes and ponds , is one of the "four major fish" in freshwater farming in my country. Therefore, there is a large demand for herring farming in my country. Among them, the main method of fish farming is pond farming. Increasing the breeding quantity of herring within the country will lead to the gradual deterioration of the breeding environment, causing harmful bacteria to have a serious impact on herring. Therefore, a herring f...

Therefore, there is a large demand for herring farming in my country. Among them, the main method of fish farming is pond farming. Increasing the number of herrings in the country will lead to the gradual deterioration of the breeding environment, causing harmful bacteria to have a serious impact on herrings. Therefore, a herring feed that can effectively inhibit harmful bacteria is needed
