[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 raising method are: (1) The mortality rate of species gin

Embodiment 1
[0037] (1) Collect wild rough sea cucumber into ginseng
[0038] Collect 50 wild sea cucumbers caught by artificial diving, with an individual weight of 100g-200g and an average weight of 157.9g / head. Individual requirements: no obvious injury on the body surface; heavy hand feel, full muscles, healthy and energetic physique.
[0039] (2) Temporary cultivation and screening of ginseng
[0040] After the ginseng is transported back to the room, it is placed in a 200L plastic basin or plastic bucket for 2 days, so that it can spit out a lot of sediment and feces in the stomach. Change the water twice a day to completely remove the dirt spit out by the sea cucumber. Carefully observe the activities of sea cucumbers, and pick out and discard the individuals with obvious skin damage or vomiting internal organs during the temporary culture.
[0041] (3) Cleaning and disinfection of the incubation tank
[0042] The cultivation pool is an indoor cement pool with an area of 10m ...

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 maturation promotion of wild rough sea cucumber in indoor cement pools. Background technique [0002] Rough sea cucumber is a 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 along the coast of South my country, and the resources were very large. After that, due to overfishing and environmental degradation, the amount of natural resources declined sharply, and only a small number of natural populations still exist in the eastern part 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 sea cucumber has only been carried out for two or three years, the scale is small, and the progress is slow....
