Method for maturing wild Holothuria scabra by manual intensive culture in indoor cement pond

Abstract

The invention discloses a method for maturing wild Holothuria scabra by manual intensive culture in an indoor cement pond. The method is carried out by the following steps of: collecting grown-up sea cucumbers of wild Holothuria scabra->fostering and screening the grown-up sea cucumbers->washing and disinfecting a breeding pond->modifying the breeding pond->feeding water into the breeding pond->disinfecting the grown-up sea cucumbers->putting the grown-up sea cucumbers into the pond->carrying out daily management measures. In the invention, by utilizing comprehensive technical measures combining the modification of environment conditions and intensification of inner nutrition, conditions including water quality, bottom materials, light illumination and the like which are close to wild habitats of the wild Holothuria scabra are created in the indoor cement pond; meanwhile, artificial compound feed with comprehensively-balanced nutrition is fed, scientific daily management is carried out to enable the wild Holothuria scabra from the natural sea to be better adapted to the indoor cultivation environment, and the survival rate reaches more than 95%; meanwhile, the wild Holothuria scabra can rapidly grow and the weight is increased from 100-200 g to 300 g in a short period (30-40 days); the growth of sexual glands of the wild Holothuria scabra are mature so that the wild Holothuria scabra can be used as seed sea cucumbers and the ratio of the group mature seed sea cucumber reaches 20%.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for artificial intensive cultivation and ripening promotion of wild rough sea cucumbers in indoor cement ponds. Background technique [0002] Coarse sea cucumber is a kind of tropical sea cucumber in my country, which has high economic value and medicinal value. In the 1970s and 1980s, rough sea cucumbers were widely distributed in the coastal areas of South my country, with a large amount of resources. Afterwards, due to overfishing and environmental deterioration, the amount of natural resources declined sharply. At present, only a small amount of natural populations exist in the east of Hainan Island in my country. In order to restore natural resources, artificial breeding and artificial breeding are necessary ways. The domestic artificial breeding of rough sea cucumbers has only been carried out for two or three years, the scale is small, and the pr...

Problems solved by technology

[0003] In the past, when artificial breeding of rough sea cucumbers was carried out, stocking ginseng species in cement ponds was only a temporary breeding measure. This kind of temporary breeding neither baited nor made any modification to the cultivation ponds.

The problems of this temporary breeding method are: (1) The mortality rate of species ginseng is relatively high, and the mortality rate is as high as 20-30% after one month of breeding; if the ambient water temperature is relatively high, the mortality rate is even higher

During the temporary breeding period, the gonads of ginseng grow slowly or even degenerate, which has a great impact on the work of artificial seedling breeding
