Sea cucumber stocks have been overexploited in the wild, resulting in incentives to grow them by aquaculture. Aquaculture means the sea cucumbers are farmed in contained areas where they can be cultured in a controlled manner. In China, sea cucumbers are cultured, along with prawns and some fish species, in integrated multi-trophic systems. In these systems, the sea cucumbers feed on the waste and feces from the other species. In this manner, what would otherwise be polluting byproducts from the culture of the other species become a valuable resource that is turned into a marketable product.

The invention discloses a culture method of sea cucumber in the aquiculture field. A simulative seawater-culture pond and a natural seawater-culture pond are arranged. An arched shed is arranged above the simulative seawater-culture pond and is covered with a diaphanous film and a shady covering. The water used in the simulative seawater-culture pond is prepared by blending natural sea water with seaside well water containing salt, the salt content of the water ranges from 2.9% to 3.6%, and the water temperature is adjusted by controlling the proportion of the natural water to the seaside well water containing salt. Through the stages of spring culture, summer culture, autumn culture and winter culture, the method can avoid the aestivation and hibernation of sea cucumber, thus realizing the perennial growth and development of sea cucumber; compared with the natural aquiculture, the yield is enhanced. The method is applicable to the artificial culture of sea cucumber.

The present invention provides a processing technology of a sea cucumber cultivation feed. The preparation method of the sea cucumber cultivation feed includes following specific steps: raw materials-grinding-mixing-superfine grinding-cooking-granulating-grinding. The raw materials are coarsely ground respectively, added into a mixer, mixed evenly, then placed in a superfine pulverizer, ground to over 80 mesh, granulated by passing through a granulator, sealed packaging after being ground to needed granules once again. The nutritional components of the sea cucumber feed prepared by the invention have the advantages of better stability, rich and balancing nutrition, the hand-fed sea cucumber has better development, quick growth rate which is 1.5-2.0 times faster than that of sea cucumbers fed with the traditional cultivation method, thereby greatly improving the production efficiency of the sea cucumber cultivation, meanwhile, reducing the pollution to aquaculture water.
