Port mariculture box

The invention relates to a port mariculture box. The port mariculture box comprises a main body which is placed on the ground, wherein mariculture organisms are placed in the main body to be cultured and stored; airflow grooves which are rectangular open grooves with openings formed in the two sides, close to the top end, of the main body; a crushing shaft which is a circular shaft, wherein the two ends of the crushing shaft are inserted and embedded in the airflow grooves, close to the two sides of the top end, in the middle of the main body. According to the port mariculture box, when airflow in cold wind blows to the airflow grooves in the main body, the airflow flows to drive the crushing shaft to rotate and move around the water surface in the middle of the main body, so that an ice layer condensed into ice on the water surface due to the cold air in the cold wind is beaten and crushed. The situation that since water surface icing caused by too low temperature on the water surface of the main body, breed
