Fish feed additive preparation method

Abstract

The invention provides a fish feed additive preparation method. The method is characterized in that the method comprises the following steps: dissolving 100 parts by weight of ammonium humate having a water solubility of above 90% in 200-250 parts by weight of water, filtering for residual removal to obtain an ammonium humate solution, sequentially adding 3-15 parts of sodium hydroxide, 3-15 parts of ferric phosphate, 3-15 parts of calcium phosphate, 3-5 parts of selenium oxide and 15-30 parts of N, P and K to the ammonium humate solution to obtain a fish feed additive mixed solution, adding amino acids to the fish feed additive mixed solution according to a ratio of 100-500g / L, and uniformly mixing to obtain a fish feed additive. The invention also provides the fish feed additive prepared through the method. The additive can maintain the healthy and rapid growth of fish, effectively inhibit the viability of water surface algae and other fish pathogens and maintain good culture water quality, and is a green fish culturing product.

Description

technical field [0001] The invention relates to a preparation method of an additive, in particular to a preparation method of a fish feed additive. Background technique [0002] China is the world's largest aquaculture and aquatic product trading country, and its fish and aquatic product farming volume accounts for 70% of the world's total. Among them, the cultivation of freshwater fish is about 5.66 million hectares, and that of marine fish is about 1.7 million hectares. 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 exa...

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
