Device for improving fishing quality of mudflat shellfish products

The utility model discloses a device for improving the catching quality of mudflat shellfish products, which can enable shellfish to contract adductor muscles in advance to close shells before the shellfish is harvested, and prevents the conditions that the adductor muscles are not contracted in time due to sudden impact of high-pressure water flow in the shellfish harvesting process, the shells are not closed, and the shellfish bodies are choked by mud and sand, so that the shellfish products are prevented from being damaged. A strong stress reaction is caused, and the survival rate and the eating taste of the shellfish are directly influenced; meanwhile, in the shellfish harvesting process, the device can collect a bottom mud sample of a mudflat shellfish culture area, and pressure data and vibration frequency data generated by rolling of the device are continuously collected through a pressure sensor and a vibration sensor; by applying the shellfish catching device, the stress reaction of shellfishes can b
