Problems solved by technology

[0007] The technical problem to be solved by the present invention is that the main bait benthic plants of sea cucumber in the existing sea cucumber pond culture grow slowly and less, the water quality is poor, the culture cost is high, and the labor load is large. For the above problems, the purpose of the present invention It is to provide a non-baiting and environment-friendly method for cultivating sea cucumbers in ponds with sufficient bait growth, no need for baiting, easy management, small labor, good water quality, large breeding volume, and low cost, and overcomes the deficiencies in the prior art

Embodiment Construction

[0024] In the non-baiting and environment-friendly sea cucumber cultivation method of the present invention, the nitrate nitrogen content in the seawater in the pond is controlled to be 80 μg / L or 85 μg / L or 90 μg / L or 95 μg / L or 100 μg / L or 105 μg / L Or 110μg / L or 115μg / L or 120μg / L, that is, it can be between 80μg / L-120μg / L;

[0025] The ammonia nitrogen content of seawater in the pond is 100 μg / L or 200 μg / L or 275 μg / L or 300 μg / L or 350 μg / L or 400 μg / L or 450 μg / L, that is, it can be controlled between 100 μg / L and 450 μg / L;

[0026] The nitrite nitrogen content of seawater in the pond is 75μg / L or 75μg / L or 80μg / L or 85μg / L or 90μg / L or 95μg / L or 100μg / L, that is, controlled between 70μg / L-100μg / L Can;

[0027] The soluble phosphate content of the sea in the pond is 15 μg / L or 18 μg / L or 20 μg / L or 22 μg / L or 25 μg / L, that is, it can be controlled between 15 μg / L and 25 μg / L;

[0028] The water depth in the pond should be kept less than the transparency of the water in...

Abstract

An environment friendly method for culturing the spiny sea cucumber in pond without feeding bait features that the contents of the N in nitrate, ammoniacal nitrogen, the N in nitrite and the soluble phosphate in the seawater in pond are controlled respectively to be 80-120 micrograms / L, 100-400 micrograms / L, 70-100 micrograms / L and 15-25 micrograms / L, and the water depth in pond is less than the transparency of said water.

Description

technical field [0001] The invention relates to a method for cultivating seafood, in particular to a non-baiting and environment-friendly method for cultivating sea cucumbers in ponds. Background technique [0002] Apostichopus is the collective name of Echinodermata, and there are more than 900 species of Apostichopus, all of which live in the ocean. There are about 40 edible Apostichopus species in the world. There are 140 species of japonicus in my country, and about 20 species of japonicus are edible, among which the japonicus (imitation japonicus) [Apostichopus japonicus (Selenka)] produced in the northern coast is of the best quality. Sea cucumber has high nutritional and medicinal value. Hundreds of years ago, people regarded sea cucumber as a precious seafood and listed it as one of the "Eight Treasures" of seafood. There are records about sea cucumber in "Wuzazu" of Ming Dynasty. In the "Compendium of Materia Medica Supplements" edited by Zhao Xuemin at the end of...
