Abstract

The invention belongs to the technical field of aquiculture feed and particularly relates to juvenile red tilapia microcapsule feed. The juvenile red tilapia microcapsule feed is prepared from fish meal, krill meal, beer yeast, shark liver oil, corn gluten meal, linseed oil, a wall material, lecithin, choline chloride, sodium carboxymethyl cellulose, a vitamin mixture and a mineral mixture. By adoption of the composite wall material, prepared microcapsules 178-590micron in particle size distribution account for 70%, generation of dust and large-particle feed is sharply reduced, the feed meetsfeed particle size requirements of juvenile red tilapia, the utilization rate and the absorption rate of fish meal and other raw materials are increased, tilapia immunity is improved, and the low-temperature survival rate of tilapia is increased.

Description

technical field [0001] The invention belongs to the technical field of aquatic feed, in particular to a microencapsulated feed for juvenile red tilapia and a preparation method thereof. Background technique [0002] Malaysian red tilapia is a strain of red tilapia with excellent economic properties obtained through several generations of improvement. Lack of suitable bait, mainly rely on natural bait, so the growth is slow, the individual is small, not resistant to severe cold, the survival rate of overwintering is low, and its seedlings are lacking, only Hainan and Malaysia can buy it locally, resulting in basically no special breeding in China The breeders or companies of the Malaysian strain are still in the research and development stage, mainly for some research structures to study the basic biological characteristics and quality selection of the strain. At present, the experimental field of red tilapia in Malaysia mainly carries out the research and development of its...
