Mixed feed special for greenling larva culture

Abstract

The invention provides mixed feed special for greenling larva culture. The mixed feed is prepared from, by weight, 15-62 parts of animal nutriment, 14-55 parts of plant nutriment, 4-20 parts of microbial nutriment, 1-6 parts of spray-dried animal blood cells, 1-6 parts of spray-dried plasma protein powder, 1-5 parts of casein, 1-5 parts of whey powder, 1-5 parts of L-lysine, 1-5 parts of taurine, 1-5 parts of D-biotin, 1-5 parts of glycine betaine, 1-5 parts of vitamin and 1-5 parts of microelements. On the basis of fully studying the growing and feeding characteristics of greenling larvae, through combined matching of the animal nutriment and the plant nutriment, more balanced nutrients are provided for growth of the greenling larvae. Through the added microbial nutriment, the physique of greenling is enhanced, and diseases are reduced. By specifically adding the vitamin and the microelements, the situation of malnutrition of the greenling larvae is reduced, and the situation that the individual variation existing in the growth process of the greenling larvae is large is reduced.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a compound feed specially used for the breeding of juvenile and juvenile carp. Background technique [0002] Distributed in the shallow waters of the northern Pacific Ocean. my country's Yellow Sea and Bohai Sea coasts have a certain amount of production, of which the coastal areas of Liaoning Province produce more. Its body length is slightly flat on the side, generally 30 to 40 cm in length, and there are also large six-line fishes exceeding 60 cm. Although it belongs to the scorpionidae, its unique feature is that its scales are smaller than other close relatives. The weight is about 250-1000 grams. The dorsal fin is quite long and continuous. There is a deep depression between the fin spine and the fin rays. There is a large black-brown spot on the back and upper part of the fin spine. Six-line carp is one of the important economic fish in my country, with beautiful appearanc...

Problems solved by technology

[0003] In the current breeding process of hexagonal juveniles, general-purpose seawater fish feed is generally used for breeding, without considering the feeding and nutritional characteristics of hexagonal fish, resulting in the feed being fed cannot effectively meet the needs of hexagonal juveniles. Physiological and nutritional requirements not only cause waste of feed materials, but also make the breeding cycle of six line fish longer and lower the breeding efficiency
