Sea cucumbers can be raised, but the nutritional value of the raised sea cucumbers is relatively lacking, but many people still choose artificial breeding because the profits are considerable. Sea cucumber has strict requirements on water quality. Site selection, construction and sanitary conditions. Farms shall conform to the tidal flat breeding plan formulated by the local fishery administrative department. The construction of aquaculture ponds should scientifically and reasonably determine the size, form and scale of aquaculture ponds according to different breeding varieties, models and conditions. In terms of water inlet and drainage channels, it is required that the water inlet and drainage channels should be as far away as possible, and the water inlet and drainage channels should be set independently. Newly built farms should not be close to the water inlet and drainage channels of existing farms.
Before breeding, the sewage and sundries in the breeding pond should be removed with seawater, and the inlet and outlet canals in the pond should be well maintained. When choosing a cement pond as a breeding pond, it must be washed repeatedly. When choosing a pond as a breeding pond, it is necessary to dredge and expose the place with thick sediments to promote the decomposition of organic matter. Found dead individuals should be moved to land as soon as possible, centralized destruction.
Sea cucumber is suitable for living in the sea area with clear water quality, stable tide and rich bait, and can also live in the sea area with temporary big waves and turbid water quality. The requirement of water temperature is that it can survive at -3℃-34℃, and the optimum temperature is 12℃- 18℃. When it exceeds 20℃, it will enter a dormant state, and when it is below 5℃, it will stop growing. Salinity should be between 18-33‰. In terms of sediments, hard sediments are suitable for the growth of Japanese groupers, especially where rocks, reefs, aquatic plants and seaweed are abundant.
