Energy-saving emission-reducing haliotis diversicolor supertexta culturing method

Abstract

The invention discloses an energy-saving emission-reducing haliotis diversicolor supertexta culturing method, which comprises the steps of: (1) culturing aquatic plants, (2) adding nutritive salt, (3) picking seedlings and distributing eggs by exchanging the water in an aquatic plants culturing pool, adding the mixed preparation of leech and vibrio till the initial concentration of the mixed preparation in the pool water reaches to 10 to 107pfu / ml, and arraying forty thousand to fifty thousand germ cells of haliotis diversicolor supertexta in each pool, (4) exchanging the water: exchanging the water in pool every 5 to 30 days and adding the mixed preparation of leech and vibrio after exchanging the water every time till the concentration of the mixed preparation in the pool water reaches to 10 to 107pfu / ml, and (5) peeling off and harvesting. The culturing method of the invention has obvious facilitation to the growth of haliotis diversicolor supertexta, greatly increases the livability of the haliotis diversicolor supertexta and improves the water quality of the culturing environment. The leech and the vibrio are non-toxic to abalone, therefore being fit for the large-scale industrial culturing of abalone and providing a new culturing technique for boosting the culturing and growth of the haliotis diversicolor supertexta.

Description

technical field [0001] The invention belongs to the field of aquaculture shellfish seedling raising methods, in particular to a novel, water-saving, energy-saving, green and environment-friendly seedling raising method capable of promoting the growth of haliotis diversicolor aquatilis abalone seedlings. Background technique [0002] Abalone is one of the eight sea treasures in my country, which has high economic and medicinal value. my country's abalone farming started in the 1970s, and has formed a large-scale production in the mid-1980s. Since then, it has developed rapidly, and the abalone farming industry in coastal areas has formed a relatively large scale. However, with the aggravation of environmental pollution, the expansion of aquaculture scale and the improvement of intensification, the diseases of abalone seedlings have occurred one after another, and there is a trend of increasing year by year, which has constituted a serious threat to the development of my count...

AI Technical Summary

Problems solved by technology

At present, the conventional method to prevent and control abalone dropping is mainly to apply antibiotics regularly. The advantages of antibiotics are that the drugs can be directly put into the water, the concentration is high, the absorption is fast, and the curative effect is good; the disadvantage is that it may cause irritation to abalone and cause new diseases.

If antibiotics are used in large quantities for a long time, it will not only increase the resistance of pathogenic bacteria, but also make some abalone cases difficult to cure

In addition, antibiotic residues in abalone will affect the quality of abalone, which is not conducive to sales, which will cause economic losses to farmers

Chinese herbal medicine is also a common way to prevent abalone from falling off. Although it has the advantages of no drug residue and high economic benefits, it also has the disadvantage of slow effect. Therefore, it is extremely urgent to find a more efficient and economical method of raising seedlings.
