The utility model provides a breeding holothuria scabra wintering system. The system comprises a wintering pond, a heat insulation greenhouse and a water inlet and outlet system, wherein the wintering pond is built at a place not far away from the seaside, a constant-temperature water heater and an air pump arranged in the wintering pond can reasonably control the water temperature and dissolved oxygen in the wintering pond, sea sand is laid at the bottom of the wintering pond to meet the demand of holothuria scabra for inhabiting under the sand, filtered and sterilized natural seawater and efficient sewage design enable the water quality in the pond to be maintained effectively, and a ventilation port and a sun-shading window arranged in the heat insulation greenhouse can conduct cross-ventilation periodically and control the light intensity in the wintering system. By the adoption of the breeding holothuria scabra wintering system, requirements of a breeding holothuria scabra wintering environment can be met basically, the morbidity and death rate of the holothuria scabra during wintering can be reduced, successful wintering of the breeding holothuria scabra is achieved, and robust breeding holothuria scabra is finally provided for artificial breeding of the holothuria scabra. The wintering system has the advantages of being reasonable in design, controllable in condition, easy to manage and the like.
