Energy-saving method for culturing haliotis diversicolor aquatilis

Abstract

The invention discloses an energy-saving method for culturing haliotis diversicolor aquatilis. The method comprises the following steps of: (1) culturing algae; (2) adding nutrient salt; (3) collecting the spats and distributing eggs, namely, changing water in an algae culturing pool, adding bdellovibrio bacteriovorus plasmid bacterial liquid into the pool until the concentration of bdellovibrio bacteriovorus plasmid in the pool water is between 10 and 107 pfu / mL and distributing 40,000 to 50,000 haliotis diversicolor aquatilis fertilized eggs in each pool during spat distribution; (4) changing water, namely, changing the pool water once every 5 to 30 days and adding the bdellovibrio bacteriovorus plasmid bacterial liquid into the pool water after the water is changed each time until the concentration of the bdellovibrio bacteriovorus plasmid in the pool water is between 10 and 107 pfu / mL; and (5) stripping and collecting. The spat culturing method remarkably promotes the growth of the haliotis diversicolor aquatilis, greatly increases the survival rate of the haliotis diversicolor aquatilis and improves the water quality of a culturing environment. The bdellovibrio bacteriovorus plasmid does not have toxic or side effect on abalone, so that the method is suitable for large-scale culturing of the abalone and provides new culturing technology for promoting the spat culturing and growth of haliotis diversicolor aquatilis.

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] Nine-hole abalone (also known as variegated abalone) is one of the important economic species of Abalone in the southern sea area of ​​my country. Due to the advantages of fast growth and relatively low requirements for breeding conditions, this kind of abalone has now developed into Taiwan and other countries. The most important cultured species of Babaceae in the southeast coast of the mainland. However, since 2000, a large number of artificially cultivated abalone seedlings have died from Fujian to the coast of Hainan, and more than 90% of the abalone seedling farms failed to cultivate abalone seedlings, forcing many farmers to give up breeding...

AI Technical Summary

Problems solved by technology

However, the long-term use of antibiotics, especially the abuse of antibiotics, will also lead to the imbalance of normal flora in the gastrointestinal tract of abalone, which will have a negative impact on the immunity of the body of abalone, and cause side effects such as drug resistance and drug residues, which will cause serious adverse effects on the aquaculture industry and consumers. of human health have posed potential hazards

In addition, some Chinese herbal medicines are used for prevention and treatment, but there is a shortcoming of slow effect.
