Starter feed for leopard coral groupers and preparation method of starter feed

Abstract

The invention discloses a starter feed for leopard coral groupers and a preparation method of the starter feed. The starter feed for leopard coral groupers is prepared from the following components inpercentage by mass: 15-50% of euphausia superba powder, 10-20% of enzymolysis protein, 1-5% of hydrolyzed protein, 10-20% of high gluten flour, 5-8% of beer yeast powder, 5-8% of fermented soybean meal, 4-10% of artemia salina, 2-4% of spirulina, 2-10% of sandworms, 1-3% of phosphatide, 2-4% of betaine, 1-2.5% of fish oil, 1-2% of a vitamin mixture, 1-3% of a mineral element mixture, 2-4% of an immunopotentiating agent, 1-2% of bacillus subtilis, 0.3-0.8% of astaxanthin, 0.3-0.8% of rhodop seudanonas palustris, 0.3-0.8% of prodigiosin, 1-2% of a phagostimulant, 1-5% of EPA and 1-6% of DHA. Through adoption of the starter feed disclosed by the invention, the problems that a natural biological bait is instable in supply and quality, carries pathogenic bacteria easily and pollutes water quality are solved, nutrient substances are rich, more importantly, the starter feed conforms to a nutritional requirement law of leopard coral grouper fries, the food calling properties are high, and thestarter feed has the advantages of strengthening starting feed, promoting growth and increasing the survival rate.

Description

technical field [0001] The invention belongs to the technical field of aquaculture. More specifically, it relates to an east star spot opening material and a preparation method thereof. Background technique [0002] Dongxingban has bright colors, rich nutrition, tender meat, delicious meat, high protein, low fat, low cholesterol, high economic value, and because of its bright colors, it has good ornamental value, and is favored by consumers , has broad market prospects. With the expansion of the consumer market of dongxingban, artificial breeding of dongxingmai has developed rapidly in Taiwan and Hong Kong, and coastal areas such as Hainan, Guangdong, and Fujian have also begun artificial breeding of dongxingban. [0003] Affected by biological characteristics and breeding methods, there are still large differences in nutritional requirements between Dongxing grouper and other groupers. At the same time, due to the large differences in the nutritional requirements of Dong...
