Abstract

The invention discloses a seawater net cage aquaculture method for stichopus japonicus. The seawater net cage aquaculture method comprises the steps of selection of an aquaculture sea area, net cage arrangement, stichopus japonicus fry feeding and aquaculture management. In the selection of the aquaculture sea area, the sea area is required to be 1,000-2,000m off the shore, is high in water quality, does not have a red tide and is rich in natural organic baits; in the net cage arrangement, a net cage rack consists of wood boards and floaters, and 4-8 rows of net cage racks are arranged in the sea in the tide direction; 20-50 net cages are connected in each row; in the stichopus japonicus fry feeding, the specification of selected fries is 60-80 pieces per kilogram, and the density of the fed fries is 4.5-5.0 kilograms per cage; healthy stichopus japonicus fries are selected; the aquaculture management comprises four steps of feeding baits, preventing harmful organisms, cleaning impurities and setting a warning device. The seawater net cage aquaculture method is convenient to use; by net cage aquaculture, the possibility that the stichopus japonicus is injured can be reduced, the survival rate of the stichopus japonicus is increased, the yield of the stichopus japonicus is improved, and the demand of the market can be met.

Description

technical field [0001] The invention relates to the field of sea cucumber cultivation, in particular to a sea cucumber cultivation method in seawater cages. Background technique [0002] Sea cucumber is a kind of sea cucumber. It contains trace metal elements, acidic mucopolysaccharides and sea cucumber saponins. It has the effects of strengthening the brain and intelligence, enhancing immunity, relieving diabetes, and preventing cancer. It is a good food therapy. Because of its high nutritional value, its economic value is also high, so people widely start to catch sashimi. However, due to limited production and unique living environment, the supply exceeds demand, and a sea cucumber breeding method is needed to meet market demand. Contents of the invention [0003] The object of the present invention aims at solving the difficult problem of sea cucumber cultivation, and provides a kind of sea cucumber culture method of sea cucumber. [0004] In order to achieve the abov...
