Preparing method of fish feed additive

Abstract

The invention discloses a preparing method of a fish feed additive. The fish feed additive is prepared from, by weight, 100 parts of ammonuim humate with water solubility of 80% or above, 250-300 parts of water, 8-20 parts of sodium hydroxide, 8-20 parts of ferric phosphate, 8-20 parts of calcium phosphate, 5-10 parts of selenium oxide and 30-40 parts of N, P and K. The preparing method comprisesthe steps of dissolving the ammonuim humate in the water, filtering and deslagging to obtain an ammonuim humate solution, and then sequentially adding the sodium hydroxide, ferric phosphate, calcium phosphate, selenium oxide and N, P and K into the ammonuim humate solution to obtain a mixed solution of the fish feed additive. According to the fish feed additive prepared by means of the method, thecost of fish breeding feeds can be reduced, and the freshness and tenderness of the fish flesh can also be guaranteed; meanwhile, the fish growth period is significantly shortened, the quality of fish breeding water can also be improved, the water transparency is improved, and the landscape effect of a fish pool is improved.

Description

technical field [0001] The invention relates to a preparation method of a fish feed additive. Background technique [0002] In the existing fish farming process, in order to increase fish farming output, prevent, control and treat aquatic product diseases, insects, and damage, and promote the healthy growth of cultured species, a large amount of fish bait, fish fertilizer, and fish medicine are often put in, although to a certain extent It can increase the production of fish farming and prevent frequent outbreaks of fish diseases, but at the same time, it will cause the deterioration of the water quality of the farming (for example: algae on the surface of the water), so that various toxins will continue to be enriched in the fish body, leading to potential food safety problems in fish food , affecting the healthy development of the entire aquaculture industry. Therefore, how to provide a kind of green fish farming product, can effectively purify water quality while guarant...
