Low-fish-meal turbot compound feed and preparation method thereof

Abstract

The invention discloses a low-fish-meal turbot compound feed which comprises the following components in parts by mass: 25-30 parts of white fish meal, 18-25 parts of chicken meal, 4-5 parts of squid liver meal, 20-25 parts of composite plant protein, 11-16 parts of starch, 3-4 parts of fish oil, 3-4 parts of calcium hydrogen phosphate, 0.05-0.1 part of threonine, 0.4-0.5 part of methionine, 0.1-0.2 part of lysine, 0.2-0.4 part of choline chloride, 0.1-0.2 part of lycine, 0.3-0.4 part of taurine, 1-1.5 parts of vitamin premix for salt water fish and 1-1.5 parts of mineral salt premix for salt water fish. A preparation method of the low-fish-meal turbot compound feed comprises the following steps: mixing the components except the fish oil, uniformly stirring, performing superfine grinding, passing through a sieve of 80-100 meshes, admixing the fish oil, and conventionally granulating to obtain the finished product. Less fish meal is consumed, resources are saved, and the cost is low. Experiments indicate that turbots have high survival rate and high growth speed after the formula feed is used.

Description

[0001] technical field [0002] The invention relates to a seawater fish feed, in particular to a low-meal turbot compound feed, which belongs to the technical field of seawater culture. Background technique [0003] turbot( Scophthalmus maximus ), Plaiceiformes, Flounderidae, commonly known as "Turbofish", is a rare bottom-dwelling cold-water seawater fish, which has the advantages of fast growth, high meat yield, good meat quality, and high nutritional value. It has great potential for breeding and market Huge, it has become an important species of mariculture in the northern coast of my country, and its output ranks first in the world, and it is gradually moving towards a factory-intensive farming model. In the intensive farming model, the compound feed is the material basis for the survival, growth and reproduction of fish, accounting for 60% to 70% of the farming cost, and directly affects the economic benefits of fish farming. Turbot is a carnivorous mariculture fish ...

AI Technical Summary

Problems solved by technology

In recent years, with the vigorous development of the aquaculture industry, the consumption of fishmeal has been increasing year by year. Due to resource consumption, the global supply of fishmeal has been in short supply. economic benefits; on the other hand, the extensive use of fishmeal in feed exacerbates the depletion of fish natural resources, which is not conducive to ecological balance; thirdly, the shortage of fishmeal raw materials does not meet the requirements of sustainable aquaculture development
