Ecological, high and stable yield method for apostichopus japonicas pond

Abstract

An ecological, high and stable yield method for an apostichopus japonicas pond comprises steps as follows: an apostichopus japonicas cultivation pond and an adhesion matrix are established, and according to the biological habit requirements of apostichopus japonicas, the pond which is suitable for the apostichopus japonicas to grow is established in combination of actual conditions; apostichopus japonicas seeds are put as follows: under the general condition, more than 600 pieces / kg of large seedlings are put according to the appropriate specification of 10 pieces per square meter to 20 pieces per square meter, and the larger the specification is, the less the seedlings are put per unit area; the management of the apostichopus japonicas seeds is as follows: more water is added to the pond when winter comes, and changes of dissolved oxygen and bottom materials are paid more attention; and prevention and control of sea grass are as follows: when the temperature of water in the pond rises in spring, fertilizer is firstly added to reduce water transparency, and the breeding of the sea grass is controlled.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to an ecological high-yield and stable-yield method for japonicus ponds. Background technique [0002] Sea cucumber, as a kind of sea treasure, plays an important role in providing food, drug raw materials, nutrition and health food. Sea cucumber (Apostichopus japonicus) is the species with the best quality, the widest distribution and the largest yield among domestic edible sea cucumbers. Its breeding areas are mainly distributed in Liaoning, Hebei, Shandong and the northern coastal areas of Jiangsu. In the 1980s, the artificial breeding technology of sea cucumbers in my country had a breakthrough, and a relatively complete production technology system has been formed so far. The area of ​​japonicus breeding continues to expand. The area of ​​japonicus breeding in Shandong and Liaoning is more than 30,000 m2, and the output value exceeds 10 billion yuan. However, in recent years, problems...

Problems solved by technology

After summarizing the practical experience of sea cucumber cultivation in ponds for many years, it is found that the main reasons for the above phenomenon are the low standards of existing sea cucumber ponds, non-standard cultivation methods, and the lack of popularization of many advanced technical measures
