Compound ecotype feed for adult-stage Japanese eels

Abstract

The invention relates to a compound ecotype feed for adult-stage Japanese eels. The feed comprises the following raw materials in parts by weight: 55-65 parts of New Zealand white fish meal, 20-24 parts of pre-gelatinized starch, 1-3 parts of Antarctic krill meal, 1-4 parts of frozen fish oil, 2-5 parts of brewer's yeast, 0.2-0.5 part of mineral substance, 0.5-1.5 parts of calcium dihydrogen phosphate, 0.2-0.3 part of choline chloride, 1-4 parts of spirulina, 0.2-0.5 part of multi-vitamin, 0.1-0.3 part of coated vitamin C and 0.12-0.34 part of astaxanthin. According to the invention, the compound ecotype feed for the adult-stage Japanese eels is rich in nutrients, good in viscoelasticity, good in intake stimulating property, easy to digest, and high in feed conversion rate. Ensuring the healthy and fast growth of the adult-stage Japanese eels, the feed can effectively relieving the pollution of aquaculture water body and achieve the effects of low costs, high benefits and low pollution.

Description

technical field [0001] The invention relates to the field of compound feed, in particular to an ecological type compound feed for adult Japanese eels. Background technique [0002] The Japanese eel belongs to the family Eelidae, also known as the river eel, which belongs to the bony fish class, the order Eelidae, and the family Eelidae. In Japan, South Korea, North Korea and my country's coastal areas. Because of its tender meat, rich nutrition and delicious taste, it is favored by consumers and has remarkable breeding benefits. In the early days of Japanese eel farming, biological bait was mainly used, but the water quality was easily damaged. The deterioration of water quality and frequent water changes seriously affected the survival rate and the safety of aquatic products. [0003] With the improvement of people's living standards, more and more attention has been paid to food safety issues. In the process of aquaculture, an important link to ensure the safety of aquat...
