Artificial temperature control factory culture (1). Infrastructure ： 1) .Workshop The aquaculture pond is in a plastic greenhouse and is a brick and cement structure. The top of the roof is a suitable artificial reference reef within the steel frame , which will keep warm and avoid light and keep the water temperature better. 2).Aquaculture pond The bottom area is generally 30 to 100 square meters. The pool depth is generally 60 to 70cm. The shape of the pool is round. The bottom of the tank is in the form of a pot bottom, and is gradually tilted from the edge of the pool towards the center of the pool. The slope is 3% to 10%. A porous drainage pipe is installed on the outlet of the pool and the overflow level is controlled by an overflow pipe outside the pool. 3). Lighting equipment In order to facilitate the operation and management of staff in the breeding shed, lighting equipment must be properly installed in the shed. Leakproof switches and waterproof lights should be installed. Safety and ease of operation are required. 4) .Inflatable oxygen equipment There are mainly Roots blowers and air compressors. There are aeration stones in the aquaculture tanks. Generally, 2 to 3 pneumatic stones are installed every three square meters. The dissolved oxygen content in the pool after inflation cannot be lower than 5 mg/L. 5). Water source Natural seawater Underground deep well water 6) .Heat Exchange Equipment The heat exchange mode is to reduce the temperature of natural seawater in summer and increase the temperature of natural seawater in winter which promote the growth of sea cucumber to reduce the dormancy period of sea
