Compound feed for Ancherythroculter nigrocauda juveniles and preparation method thereof

Abstract

The invention relates to a compound feed for Ancherythroculter nigrocauda juveniles and further relates to a preparation method of the compound feed for Ancherythroculter nigrocauda juveniles. The compound feed for the Ancherythroculter nigrocauda juveniles disclosed by the invention comprises the following ingredients in parts by mass: 21-32 parts of squid powder, 5-12 parts of peanut cakes, 6-13 parts of rapeseed meal, 2-7 parts of pork powder, 4-9 parts of bulbils, 5-11 parts of Agaricus bisporus, 3-9 parts of Synechococcus aeruginosu, 3-8 parts of Spirulina platensis, 3-7 parts of Brassica oleracea, 2-6 parts of Capsella bursa-pastoris, 1-5 parts of blueberry powder, 1-4 parts of oyster mushroom powder, 2-6 parts of fish oil, 1-4 parts of honey, 1-4 parts of corn oil and 1-4 parts of compound multivitamins. The compound feed for Ancherythroculter nigrocauda juveniles disclosed by the invention is provided on basis of energy metabolism modes and nutritional requirements of the Ancherythroculter nigrocauda juveniles, so that fish meal can be completely replaced by the compound feed. The Ancherythroculter nigrocauda juveniles fed on the compound feed are high in survival rates, low in feed coefficients and high in specific growth rates.

Description

technical field [0001] The invention relates to a fish feed, in particular to a compound feed for juvenile Pleurotus chinensis; the invention also relates to a preparation method of the above-mentioned compound feed for juvenile Pleurotus chinensis. Background technique [0002] The black tail is close to the red carp, and the lower jaw is slightly longer than the upper jaw. Eyes small, snout longer than eye diameter. Lateral line scales 65-70. The origin of the dorsal fin is closer to the tip of the snout than to the base of the caudal fin. Pectoral fins reaching or exceeding pelvic fins. Anal fin rays 3, 23-28. Pelagic fish, staple food small fish. The individual is not large, and the common person has a body length of 150-300 mm. It is a protective fish and is distributed in the upper reaches of the Yangtze River. [0003] At present, fishmeal is widely used as the main protein source in compound feeds for juveniles of C. Fishmeal is the closest to the amino acid ...

AI Technical Summary

Problems solved by technology

In addition, during the growth process, the juveniles of the black-tailed red-tailed carp grow due to insufficient resistance, and various fish diseases occur, which affect the survival rate of the black-tailed red-tailed red carp. Therefore, a new method that does not rely on fish meal as the main protein source is developed. It is an urgent problem to be solved in the current aquaculture industry of black-tailed red-tailed fish that can ensure the feed quality and benefit the growth and development of young red-tailed red-tailed red-tailed fish.
