Seaweed functional feed suitable for grouper fingerlings and preparation method of seaweed functional feed

Abstract

The invention provides a seaweed functional feed suitable for grouper fingerlings and a preparation method of the seaweed functional feed. The seaweed functional feed comprises the following raw materials in parts by weight of 38-58 parts of a composite seaweed extract, 10-15 parts of taurine, 11-18 parts of glutamic acid, 12-21 parts of alanine, 10-20 parts of glycine, 14-19 parts of sodium inosinate and 2-8 parts of an antioxidant, wherein the composite seaweed extract is prepared through microwave extraction on seaweed, rhizoma kaempferiae and Chinese galls in the ratio of parts by weight being (1-3) to (2-5) to (1.2-2.6). According to the seaweed functional feed suitable for grouper fingerlings, the palatability of the feed can be changed, food calling properties can be strengthened, stress resistance and growth rate of the fingerlings can be significantly increased, the survival rate, the grazing rate and the growth rate of the grouper fingerlings can be increased, the seaweed functional feed has theory and practice directive significance in an artificial breeding technique of the grouper fingerlings and increase of breeding economic benefits, a technical base is established for large-scale breeding, and the seaweed functional feed has great social and economic benefits.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a seaweed functional feed suitable for grouper fry and a preparation method thereof. Background technique [0002] Grouper is the general term for fish in the grouper subfamily (Epinephelinae), which belongs to Osteichthyes, Neopterygii, Acanthopterygii, Perciformes, perch Suborder (Percoidei), Serranidae (Serranidae), large and medium-sized marine fishes in warm water, widely distributed in tropical and subtropical waters, mainly distributed in the Taiwan Strait and South China Sea in China. The meat is fat and delicious, and it is a popular aquatic product. Fish, but currently other chemical baits or other fry are fed in the breeding process of grouper fingerlings. Therefore, under natural conditions, the survival rate of fish fingerlings is low, the utilization rate of feed by grouper fish is low, and there is a phenomenon of vomiting when feeding. Feed The palatability is poor, an...

Therefore, under natural conditions, the survival rate of fish fingerlings is low, the utilization rate of feed by grouper fish is low, and there is a phenomenon of vomiting when feeding. Feed Poor palatability, more spoiled flavor substances, thus affecting the appetite of fish species, reducing food intake, and hindering growth
