Compound feed for preventing black sea bream body surface ulcer and preparation method of compound feed

Abstract

The invention relates to fish feed, in particular to compound feed for preventing black sea bream body surface ulcer. The invention further relates to a preparation method of the compound feed. The compound feed comprises, by mass, 20-30 parts of fish meal, 8-15 parts of maize germ cake, 4-10 parts of broken rice, 6-12 parts of dried trash fish, 3-7 parts of Fructus Schizandrae, 3-8 parts of carrot, 2-6 parts of Herba Houttuyniae, 3-7 parts of Cortex Moutan, 2-5 parts of Fructus Forsythiae, 2-6 parts of Cortex Acanthopanacis, 1-5 parts of dark plum, 1-4 parts of Folium Isatidis, 2-6 parts of Isodonis Japonicus, 1-4 parts of Fructus Ligustri Lucidi, 1-4 parts of olive oil and 1-4 parts of compound vitamin. Black sea bream after being fed with the feed is low in feed coefficient, high in specific growth rate and high in resistance to surface ulcer.

Description

technical field [0001] The invention relates to a fish feed, in particular to a compound feed for preventing body surface ulcers of black sea bream; the invention also relates to a preparation method of the compound feed for preventing body surface ulcers of black sea bream. Background technique [0002] Black sea bream is oblong, with flat sides, gray-black back, silver-white and shiny belly, hard spines on the dorsal fin, especially the spines on the second anal fin, except for the gray pectoral fin, the edges of the rest of the fins are black. The body is covered with ctenoid scales, and there are usually 5-7 black horizontal bands on the side of the body. The small upper and lower teeth of the black snapper snout are closely arranged, the outer edge of the head is straight, and the skull above the eyes is not raised. [0003] At present, during the cultivation process of black snapper, due to continuous fertilization and baiting, the remaining feces and residual bait ar...

Problems solved by technology

[0003] At present, during the cultivation process of black snapper, due to continuous fertilization and baiting, the remaining feces and residual bait are most likely to damage the water quality, which often causes black snapper to produce body surface ulcers. When people deal with fish diseases, they often use the The disease is treated by splashing bactericidal disinfectant, but the drug will more or less produce side effects or toxicity. Although it can kill the pathogenic bacteria on the surface of the black snapper and in the water, it often causes water pollution, and long-term use will cause the drug to produce Accumulate, affect the health of the body, and then affect the growth rate of black snapper

During the growth process, black sea bream often suffers from lack of resistance due to nutritional deficiencies, causing body surface ulcers and affecting the survival rate of black sea bream. The black bream compound feed for the growth and development of bream is an urgent problem to be solved in the current black bream aquaculture industry
