Large-scale cultivation method for preventing and controlling alien marine shellfish organism invasion

The invention belongs to the field of marine shellfish cultivation, and particularly relates to a large-scale cultivation method for preventing and controlling alien marine shellfish organism invasion. The method comprises the following steps of selecting an intertidal zone pond, designing the pond, making a preparation before seedling adding, carrying out seedling stocking, carrying out cultivation period management, carrying out feeding management, carrying out disease prevention and treatment, carrying out growth detection, managing a mercenaria mercenaria Linnaeus wintering period, harvesting and the like. The invention fully utilizes coastal salina intertidal zone cultivation zones in China, the mercenaria mercenaria Linnaeus and penaeus orientalis are subjected to mixed cultivation,an ecological condition of a penaeus orientalis cultivation pond is improved, a pond cultivation benefit is improved, a cultivation risk is lowered, salinity is used for carrying out reproductive andecological isolation, a pa
