The invention discloses a mixed culture method for sea cucumber and shrimp. The method includes first selecting a place, selecting several ponds with warm and ventilated, sufficient water sources, having filter pools, convenient inflow and drainage, and water depth greater than 3m as sea cucumber and shrimp culture places, and at the bottom of the pool Place the attached reefs, stones and coral stones for sea cucumbers to inhabit, and thoroughly remove the sludge at the bottom; use 50-80kg/mu of quicklime slurry to evenly sprinkle the pool to disinfect the pool; after 4-5 days of drying the pool, rinse the pool; press again 200-250g of bromochlorohydantoin per mu is used to spray and disinfect the entire pool; the pool is irrigated with underground seawater, the temperature is controlled at 12-17°C, the salinity is not less than 25‰, and the dissolved oxygen in the water is 5mg/L. The pH value is 7.8-8.5, and the transparency is 30-40cm; temperature control devices and aerators are installed in the pool, and a 1.5-kilowatt power aerator is configured for every 4 mu of water surface; the size of sea cucumber seedlings is selected in the range of 3cm-5cm Inside, sea cucumber seedlings are put in at a rate of 3,000-5,000 heads per mu. |
