AI Technical Summary

Technical Problem

During traditional trawling and transportation, hairtail eggs are susceptible to mechanical damage, temperature fluctuations and pressure changes, resulting in a low survival rate and a lack of effective protection measures.

Method used

A device for sealing and keeping trawl hairtail eggs alive was designed. The device used a rotary wing to use the power of water flow to rotate the collection tank, and the live eggs were screened by centrifugal force and collected in the storage tank. Combined with a multi-layer storage tank design, a thermostat and sensors, dead and low-quality eggs were regularly discharged, and natural water flow was simulated to increase the oxygen content and regulate the temperature and pH value.

Benefits of technology

The device improves the survival rate of fish eggs, is easy to operate and has low energy consumption, effectively screens live fish eggs, and solves the problem of the survival rate of fish eggs during fishing and transportation.

Abstract

The application discloses a trawl beltfish egg sealing and living device and relates to the field of marine aquaculture. The trawl beltfish egg sealing and living device comprises a collecting groove, the main body of the collecting groove is a cylinder, the side of the cylinder is provided with a rotating wing, the center is provided with a limiting rod, the rod body inside the collecting groove is fixed with a sensor and a thermostat, the upper portion of the collecting groove is sleeved with an annular storage groove, the collecting groove is communicated with the storage groove, the storage groove is at least two, and the storage grooves are arranged downwards in sequence from the top of the collecting groove. The collecting groove is rotated by the rotating wing and the water flow power, the live fish eggs are screened by the centrifugal force, and the live fish eggs are collected to the storage groove; the storage groove is designed as multiple layers, the fish eggs can be effectively prevented from being accumulated, the device is provided with the thermostat and the sensor, the temperature and the PH value of the water body can be monitored and adjusted in real time, and the live fish eggs can be ensured to survive in the suitable environment.
