Problems solved by technology

In order to improve the survival rate of white sand ginseng seedlings and shorten the time of medium cultivation of white sand ginseng, and at the same time solve the problems of weak resistance and low survival rate of white sand ginseng seedlings, the present invention provides a medium cultivation method , combine the indoor cement pond cultivation of white sand ginseng seedlings with the outdoor pond cage cultivation, and after cultivating white sand ginseng seedlings in indoor cement ponds for a period of time, when the resistance of white sand ginseng seedlings is slightly stronger and the mortality rate is slightly lower, turn to Entering outdoor net cage ponds for medium cultivation, using this medium cultivation method can not only shorten the time for purely outdoor medium cultivation, but also save the cost of pure indoor medium cultivation. In addition, this method is easy to manage and less labor intensive, and is suitable for industrial Promote apps on

Abstract

The invention relates to an intermediate culture method for Holothuria scabra Jaeger, and belongs to the technical field of aquatic product culture. The method comprises the two aspects of indoor cement pond intermediate culture and outdoor net cage pond intermediate culture. According to the aspect of indoor cement pond intermediate culture, the steps such as water quality control, intermediate culture density control, bait casting, water changing and pouring into a pond, inflation, disease control, daily management and intermediate culture time control are included. According to the aspect of outdoor net cage pond intermediate culture, the steps such as preparation before seedling release, seedling feeding, bait feeding, water changing and seedling thinning are included. The method facilitates management and is low in labor intensity, the quality and survival rate of the whole young Holothuria scabra Jaeger can be improved, economic benefits can be improved, and the method is suitable for application and popularization in the aspect of aquaculture.

Description

technical field [0001] The invention relates to a method for medium cultivation of white sand ginseng, in particular to a method for medium cultivation of white sand ginseng which combines medium cultivation in an indoor cement pond and an outdoor pond cage, and belongs to the technical field of aquatic product cultivation. Background technique [0002] White Ginseng (Metriatyla Scabra) Belonging to the order of Chiroptera, Holothuridae, and Holothurian genus, it is also known as rough sea cucumber and bright jade ginseng, commonly known as white ginseng, and called bald ginseng in the south. It is widely distributed in tropical and subtropical sea areas, from Sinatal Port to the Red Sea, eastward to Caroline Islands, Fiji Islands. North to Japan, south to Australia and China. There are also distributions in Guangdong, Guangxi and Hainan in my country, but the resources are scarce. White sand ginseng grows faster than sea cucumber, has larger individuals, and has strong a...
