Anti-stress bait for polyculture of haliotis diversicolor aquatilis and stichopus japonicus

Abstract

The invention relates to anti-stress bait for polyculture of haliotis diversicolor aquatilis and stichopus japonicus. The anti-stress bait comprises 13 natural raw materials including, by weight, 10%-15% of white fish meal, 20%-50% of kelp powder, 8%-15% of nori, 5%-10% of bean pulp, 3%-6% of sea float sludge, 2%-8% of sea rhodotorula, 2%-16% of ulva, 2%-4% of chlamydomonas, 1%-4% of lecithin, 0.5%-1% of photosynthetic bacteria, 0.5%-1% of bacillus subtilis, 0.5%-1% of clostridium butyricum and 0.5%-1% of chitosan. The anti-stress bait is designed according to a nutrition immune mechanism of the haliotis diversicolor aquatilis and the stichopus japonicus to environmental responses, in particular to temperature responses; the immunity of the haliotis diversicolor aquatilis and the stichopus japonicus can be strengthened, and the survival rate and the growing speed are increased; in addition, the bait caters to a new culture mode, the price is low, raw material sources are stable, the production process is simple, and the anti-stress bait is convenient to use.

Description

technical field [0001] The invention relates to a bait for breeding, in particular to a bait capable of improving the anti-stress ability of polyculture of japonicus japonicus. Background technique [0002] With the improvement of people's living standards, people's demand for seafood is increasing, which drives the rapid development of mariculture industry, and the degree of integration and intensification is getting higher and higher. The mixed culture technology of abalone and ginseng is to use the ecological complementarity of abalone to carry out polyculture, which can not only make full use of the effective water body, but also promote its mutual growth, and the economic benefit in the cycle is obviously higher than that of single sea cucumber and abalone culture, which increases the cost of breeding. Spatial stratification of water body ecological structure and spatio-temporal connection of ecological cooker. With the development of coastal abalone and japonicus aqua...

AI Technical Summary

Problems solved by technology

With the development of coastal abalone and japonicus aquaculture, high-density and intensive polyculture of abalone and ginseng is developing rapidly. The traditional breeding mode of using natural phytoplankton in seawater as basic bait is far from satisfying the normal conditions of abalone and japonicus. growth and development needs

Since the work of research institutions and feed manufacturers in the development of bait for abalone and japonicus is not systematic enough, most of the abalone baits commonly used by farmers cannot meet the nutritional and physiological needs of abalone and japonicus mixed culture at the same time. There is a lack of a special bait suitable for polyculture of abalone and japonicus in the world, resulting in high cost of breeding

Especially when nine-hole abalone moves northward and japonicus moves southward to the coastal areas of Zhejiang and Jiangsu for polyculture, due to changes in the breeding environment, especially the temperature of the breeding water, the use of traditional bait tends to slow down the growth rate of abalone, reduce immunity, and even cause serious damage. Therefore, it is imminent to develop anti-stress bait for polyculture of Abalone japonicus and improve the anti-stress ability of abalone through nutrition and immunity.
