Adult Japanese flounder feed additive and preparation method thereof

Abstract

The invention relates to an aquatic culture animal feed additive, in particular to an adult Japanese flounder feed additive, and further relates to a preparation method of the adult Japanese flounder feed additive. The adult Japanese flounder feed additive is composed of, by mass, 6-10 parts of silkworm chrysalis, 6-10 parts of earthworm, 6-8 parts of eclipta alba, 6-8 parts of ligustrum lucidum ait, 4-6 parts of ulva, 4-6 parts of shepherdspurse herb, 4-6 parts of carrot, 4-6 parts of herba houttuyniae, 3-5 parts of purslane, 3-5 parts of fructus xanthii, 3-5 parts of watermelon peel, 3-5 parts of Japanese pearlwort herb, 3-5 parts of mazus japonicus, 3-5 parts of astragalus sinicus, 1-3 parts of fresh ginger, 2-4 parts of honey, 2-4 parts of olive oil and 2-4 parts of fish oil. By means of the adult Japanese flounder feed additive, the growth of Japanese flounder can be promoted, the immunity of Japanese flounder can be improved, and Japanese flounder is high in specific growth rate and survival rate after eating the adult Japanese flounder feed additive.

Description

technical field [0001] The invention relates to a feed additive for aquaculture animals, in particular to a feed additive for adult flounder fish; the invention also relates to a preparation method for the feed additive for adult flounder fish. Background technique [0002] Flounder (Paralichthysolivaceus), commonly known as tooth slice, left mouth, partial mouth, flounder, is a rare marine fish and one of the important seawater cultured fish. Flounder is a cold-temperate benthic carnivorous economic fish. Its body is huge, its meat is tender and delicious, and it is deeply loved by consumers. It has a very broad market and high economic value. The research on artificial hatching of flounder in my country began in the late 1950s, and seedling manufacturers spread all over Shandong, Hebei, Liaoning and other provinces. Since the 1990s, the breeding of flounder has developed rapidly. In addition to cage and pond farming, Weihai, Yantai, Qingdao and other places in Shandong ar...

Problems solved by technology

[0003] Flounder is a ferocious carnivorous fish. At present, there have been some studies on the requirements of flounder for protein, fat (including essential fatty acids), vitamins, and trace elements, but high-efficiency and high-quality artificial compound feed has not yet been developed. Farmers Most of them are fed with small miscellaneous fish (some with some eel feed). Due to the difficulty in disinfection of fresh bait or minced meat bait itself, it carries a large amount of bacteria and fungi. After being swallowed, the flounder is prone to illness or death, which seriously affects economic interests. Fresh and live bait pollutes the water quality very seriously, which leads to a great increase in the incidence of flounder, which affects the development of flounder aquaculture and the improvement of economic benefits

Because fish is an aquatic organism, its digestion mechanism is different from that of mammals and livestock and poultry. Therefore, flounder usually eats little when feeding livestock and poultry feed to flounder, and it is difficult to use livestock and poultry feed additives in flounder feed. Play a role

In recent years, growth promoters have been widely used in domestic freshwater fish farming, but most of them are products banned by countries such as ethanol, hormones and antibiotics, but additives such as ethanol, hormones and antibiotics have brought hidden dangers to food safety
