Breeding method of southern holothuria scabra

Abstract

The invention discloses a breeding method of southern holothuria scabra, which comprises the steps of building a holothuria scabra culture pond, culturing parent holothuria scabra, spawning and fertilizing the parent holothuria scabra, culturing larvae, culturing young holothuria scabra and the like. The method comprises the following steps: fishing wild sea cucumbers in the ocean, intensively cultivating parent sea cucumbers, hastening to lay fertilized eggs, cultivating larvae, cultivating young sea cucumbers, screening and breeding excellent characters and the like to obtain multiple optimal new species of holothuria scabra, so that the holothuria scabra can adapt to different scales of cultivation and is ensured to adapt to pond cultivation, mud flat cultivation and other environment modes, and meanwhile, the optimal new species of holothuria scabra can be obtained. According to the method disclosed by the invention, the holothuria scabra is subjected to diversity control, so that the adaptability is stronger, the excellent holothuria scabra strain with stronger growth performance is easier to breed, breed and screen, beneficial reference is provided for breed breeding, seedling raising, breeding and scientific research of the holothuria scabra variety, a southern holothuria scabra industry chain is better developed, and good social and economic benefits are created.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a breeding method for southern rough sea cucumbers. Background technique [0002] Coarse sea cucumber, scientific name: Holothuria scabra, is an animal of the genus Holothuria in the family Holothuria. Nutritional value, economic value and health function, it is a real ecological healthy food; internationally, rough sea cucumber is also an important tropical sea cucumber breeding species and high-end aquatic products for export; distributed in the west from Natal Port to the Red Sea, East to the Caroline Islands, Fiji Islands, north to Japan, south to Australia, and Guangxi, Guangdong, Hainan and other places in mainland China, generally live on the edge of coastal reefs and sandy bottoms with fast tidal currents and many seaweeds; as An important part of sea cucumber farming, sea cucumber seedling breeding technology has been widely carried out in coastal areas of our count...

AI Technical Summary

Problems solved by technology

[0003] When the existing rough sea cucumbers are selected for breeding and breeding, the quality control of the breeding water is relatively poor. The temperature, salinity and purity of the water are likely to affect the growth of the seedlings. The seedlings cannot grow in a good cultivation environment, which will cause other The amount of foraging becomes lower, the traits are poor, and it is impossible to obtain excellent strains of rough sea cucumbers, and there is no effective method for breeding rough sea cucumbers.
