Problems solved by technology

After feeding conventional feed, it cannot meet the nutritional needs of sea fish, and the water for breeding is easily muddy, and the concentration of ammonia nitrogen and nitrate in the water will rise rapidly
Although there is recirculating water treatment, it also greatly reduces the efficiency of recirculating aquaculture

Abstract

The invention discloses a special sea fish feed for high-density recirculating aquaculture and a preparation method of the special sea fish feed. The special sea fish feed comprises the following components: white fish meal, fish meal made in china, euphausia superba meal, whey powder, casein, methionine, L-lysine, refined fish oil, cod liver oil, vital gluten, corn starch, peanut meal, special microecologics, special algae powder, functional components, decavitamin and compound trace elements. The special sea fish feed is capable of enhancing the immunity of sea fish, improving the growth speed, the survival rate and the feed conversion efficiency, and reducing the occurrence probability of malformation and albinism, is low in bait coefficient, low in feed cost in the breeding process, and suitable for high-density recirculating aquaculture of the sea fish.

Description

Technical field [0001] The present invention involves the field of feed processing technology, and specifically involves a special seawater fish feed and preparation method for high -density circulating aquaculture. Background technique [0002] The rise of industrialized circulating water breeding technology in my country has led to the rapid development of the industry of seawater fish breeding.Industrialized recycling aquaculture has also become a new breeding development direction with its small area and low water consumption rate, saving energy, and improving the efficiency of breeding. [0003] However, in the process of industrialized circulating water breeding, due to the large investment in the early stage of breeding, the pressure of cost recovery was high, and the technology has matured, the breeding producers pursue the high density of industrialized circulating aquaculture.However, in high -density environments, seafish often occur in some stress reactions.Diseases t...
