An automatic sorting device for male and female seedlings of semi-smooth tongue sole and its application method

Abstract

The invention belongs to the technical field of fish cultivation and relates to an automatic sorting device for female and male fries of Cynoglossus semilaevis and an application method thereof. The automatic sorting device for female and male fries of Cynoglossus semilaevis comprises rollers, supports, a light source control switch, a light source fixing table, a light source, an identifying platform, a fish incoming channel, an identifying channel, a retaining plate, a water inlet for the fish incoming channel, an image information acquisition and processing system, a wireless remote control, an automatic control device, a fish outgoing channel, a male fry outlet, a female fry sorting retainer, a female fry sorting retainer, and a female fry outlet. The automatic sorting device for female and male fries of Cynoglossus semilaevis allows female and male fries to be distinguished in the early farming stage of Cynoglossus semilaevis, never causes physiological stress or body surface injury to the fry, and provides increased accuracy of distinguishing female and male fries and increased survival rate. In addition, with the integration of the technical design of modern information equipment, the automatic sorting device can provide automatic distinguishing and sorting for female and male fries, female and male fries are screened more efficiently, manpower and material resources are saved greatly, and farming benefit is improved.

Description

technical field [0001] The invention belongs to the technical field of fish farming, and in particular relates to an automatic sorting device for male and female seedlings of tongue sole and a method for using the same. technical background [0002] Semi-smooth tongue sole is a large-scale warm-temperate benthic flounder, and it is also one of the three leading cultured species of flatfish in my country. It has formed large-scale aquaculture industries in coastal areas such as Shandong, Hebei, Tianjin, Fujian, and Zhejiang. The annual breeding output reaches 5,000 tons, driving the formation of an annual output value of more than 1 billion yuan. Semi-smooth tongue sole has the characteristics of significant differences in growth rate and individual size between male and female. The first-year-old half-smooth tongue sole female is 1-2 times as long as the male fish, and the body weight is 3-5 times that of the male fish. Cause the waste of bait and manpower and material resou...

AI Technical Summary

Problems solved by technology

In addition, only relying on the naked eye to judge the individual shape will result in low accuracy of male and female judgment, serious waste of manpower and material resources, and great inconvenience to production operations.

At present, there is no simple and effective method to distinguish the sex of tongue sole seedlings in the early stage of breeding, so as to achieve the purpose of sorting male and female seedlings
