Problems solved by technology

[0003] At present, the bait for deep-water cage culture of Japanese perch is usually fed with chilled fish pieces and small miscellaneous fish, which can easily lead to the destruction of fish resources, water quality pollution and disease outbreaks in the cultured sea area, and then affect normal aquaculture production.
At present, Japanese perch lacks suitable compound feed, and unreasonable feed formula leads to poor palatability of feed, slow growth of cultured Japanese perch and severe fatty liver, etc.
The emergence of these problems is not conducive to the healthy and sustainable development of Japanese perch cage culture in my country

Abstract

The invention discloses Lateolabrax japonicus puffed feed and a preparation method thereof. The feed comprises the following ingredients by mass percent: 22-30% of steam fish meal, 20-28% of peeled soybean meal, 12-20% of soy protein concentrate, 15.5-26.5% of strong flour, 1-5% of corn protein powder, 4.5-8.5% of refined fish oil, 0.5-2% of soybean oil, 2-5% of monocalcium phosphate, 1-2% of premix of vitamin and mineral salt, 0.1-0.5% of choline chloride and 0.1-0.5% of free methionine. The feed has the advantages that the nutrition is more comprehensive, the collocation of various ingredients is more balanced, the feed conversion ratio is high, thereby improving the immunity and the survival rate of Lateolabrax japonicus and reducing fatty liver phenomenon caused by feeding in the cultivation process.

Description

technical field [0001] The invention relates to an extruded fish feed, which belongs to the technical field of fish feed, in particular to an extruded Japanese perch feed and a preparation method thereof. Background technique [0002] Japanese perch (Lateolabax japonicus), also known as seven-star perch, sea perch, perch, etc., belongs to Perciformes, mullet, and perch. , Japan, North Korea and the sea area along the lower reaches of the river. It has many advantages such as fast growth rate and strong adaptability, and its meat is tender, delicious and nutritious, and is very popular among consumers. The price per kilogram of Japanese perch is more than 35 yuan, and the economic benefits of breeding are relatively high. It has become one of the main deep-water cage mariculture species in my country. [0003] At present, the bait for deep-water cage culture of Japanese perch is usually based on chilled fish pieces and small miscellaneous fish, which can easily lead to the ...
