Wintering method for parent holothuria scabra

Abstract

The invention discloses a wintering method for parent holothuria scabra. The wintering method for the parent holothuria scabra comprises the steps of selecting and treating the parent holothuria scabra for wintering, building a wintering system for the parent holothuria scabra, putting the parent holothuria scabra into the parent holothuria scabra wintering system, managing the wintering environment, managing feeding, regulating and controlling water quality, preventing and treating disease, and the like. The wintering system for the parent holothuria scabra comprises a wintering pool, a heat preservation shed and a water feeding and discharging system. As the wintering method for the parent holothuria scabra meets various requirements of wintering of the parent holothuria scabra, the parent holothuria scabra can winter safely. According to the wintering method, the wintering survival rate of the parent holothuria scabra can be substantially increased, the survival rate can reach more than 90 percent, the growth rate of body mass can reach more than 23 percent, and gonadal development quality is good. According to the wintering method and system, the current wintering problem for the parent holothuria scabra can be effectively solved, the robust parent holothuria scabra can be provided for artificial breeding of the holothuria scabra, and therefore farming benefits can be effectively achieved.

Description

technical field [0001] The invention relates to the field of sea cucumber cultivation, in particular to a method for overwintering rough sea cucumber species. Background technique [0002] rough sea cucumber ( Holothuria Scabra ) is a tropical sea cucumber, commonly known as Mingyu ginseng and white sand ginseng, which is mainly distributed in the Indo-West Pacific region. In my country, it is mainly distributed in Xisha, Nansha, Hainan Island and Xuwen, Guangdong. Coarse sea cucumber not only has high nutritional value, but also has extremely high medicinal value. It is one of the most popular edible sea treasures in southern my country. [0003] In recent years, due to excessive harvesting, the number of rough sea cucumbers has decreased year by year, and the market is in short supply. In order to solve the contradiction between the market and resources, artificial breeding and breeding of rough sea cucumbers emerged in the southern coastal areas. The first thing to over...

AI Technical Summary

Problems solved by technology

[0004] At present, there are no special overwintering facilities and methods for rough sea cucumber species. The common method is to move rough sea cucumber species to breeding ponds with heating equipment for overwintering. Due to the relatively simple wintering conditions, it is difficult to meet the overwintering needs of rough sea cucumbers. It often leads to high morbidity and mortality of rough sea cucumbers during the wintering period, and the survival rate is only 50% to 60%.
