System and method for evaluating influence of mechanical harvesting on shellfish attachment and metamorphosis

The invention provides a system and a method for evaluating the influence of mechanical harvesting on shellfish attachment and metamorphosis. The system comprises a culture device for simulating a mud flat environment, a mechanical harvesting simulation device and an observation system, the breeding device for simulating the mud flat environment comprises a breeding container used for simulating shellfish breeding on a mud flat; the mechanical harvesting simulation device is used for simulating seawater turbidity caused by mechanical harvesting of shellfishes, and the observation system is arranged above the culture device for simulating the mudflat environment, is a high-definition camera system and is used for recording the harvesting process, the sand diving behavior of the shellfishes and the attachment and metamorphosis conditions of larvae in real time. The invention further provides an operation method of the system. According to the system, the influence of turbid seawater caused by mechanical harvest
