Application of Antarctic krill powder in preparing starter feed for snappers

Abstract

The invention discloses an application of Antarctic krill powder in preparing a starter feed for snappers, and the starter feed special for the snappers. The starter feed is prepared from the following components in percentage by mass: 5-76% of Antarctic krill powder, 1-20% of soybean protein concentrate, 1-12% of cicada pupa powder, 1-5% of barley pest powder, 5-24% of low-gluten flour, 1-10% of beer yeast powder, 1-5% of a yeast extract, 4-20% of fairy shrimps, 2-4% of soybean phospholipid, 2-4% of betaine, 1-2.5% of a vitamin mixture, 2-5% of a mineral element mixture, 1-5% of bifidobacteria, 1-5% of an immunopotentiator, and 0.1-0.5% of lilac, wherein the fluorine content of the Antarctic krill powder is lower than 1mg / kg. The special starter feed is developed in accordance with the physiological digestion characteristics, the growth characteristics and the feeding preferences of the young snappers at the starter stage, has excellent food calling properties, and can fully meet nutrient requirements of the snappers at the starter stage, and the immunity, the stress resistance, the survival rate and the weight gain rate can be increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture. More specifically, it relates to the application of Antarctic krill powder in the preparation of snapper feed. Background technique [0002] Sea bream belongs to the fish class, seabream (SeaBream) family, with high body and flat side, more than 50cm long, silvery red body with light blue spots, greenish black behind the caudal fin, large head, small mouth, conical front of upper and lower jaw teeth, Rear molar-shaped, body covered with ctenoid scales, dorsal and anal fins with hard spines. It is produced all along the coast of China, with Dadonggou in Liaoning, Qinhuangdao in Hebei, Yantai, Longkou and Qingdao in Shandong as the main production areas. Sea bream is rich in nutrition, rich in protein, calcium, potassium, selenium and other nutrients, which can supplement rich protein and minerals for the human body. Traditional Chinese medicine believes that sea bream is an important edible...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to overcome the lack of research on the existing sea bream fry opening technology and the problem of high fluorine content in Antarctic krill meal, prepare Antarctic krill meal with a fluorine content lower than 1 mg / kg, and then optimize a The special opening feed for sea bream is developed for the growth, physiological digestion characteristics and feeding preference of sea bream seedlings at the opening stage. The special opening feed has a good food-attracting performance for sea bream seedlings, which can fully meet the nutritional needs of sea bream seedlings during the opening stage and improve Immunity, anti-stress ability, survival rate and weight gain rate
