Problems solved by technology

[0006] The purpose of the present invention is to solve the problem of high cost caused by breeding male sturgeon together due to the long breeding cycle of sturgeon broodstock and the difficulty of early gender identification in the production process of sturgeon caviar, and to provide a physical Function and early stages of male and female gonad development of sturgeons respond to different echograms generated by ultrasound to quickly and effectively identify males and females of sturgeons. It does not cause harm to fish and can observe dynamic images with good reliability.

Embodiment Construction

[0026] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings. exist figure 1 Among them, at first present embodiment selects specific place to carry out, is provided with basic facilities such as ultrasonic portable scanner, metal or wooden band grooved fish table, chooses a Russian sturgeon of 2Kg, fish age more than 2 years, is placed on In the groove of the fish table, the belly of the fish faces the operator, and the head of the fish faces left.

[0027] Ultrasonic examination is carried out on the front side. Use the right hand to hold the sensor and press it on the third to fourth bone plate from the pelvic fin of the fish, so that one side of the sensor is directly above the bone plate. You can bend the sensor to the left or right to find the best position. Observe the dynamic picture in real time on the screen, and the position of each organ and tissue of ...

Abstract

The invention relates to a method for classifying males and females of a fish, in particular to a method for examining early sexual glands of sturgeons by using physical functions of ultrasonic waves,and identifying male and female sturgeons according to an echogram generated in the process of examining the sturgeons by the ultrasonic waves. The method not only causes no injuries to the fishes but also can observe dynamic pictures, has the advantages of reasonable process means, precise processes and high diagnostic accuracy, and is a safe and reliable method for identifying the male and thefemale sturgeons by the ultrasonic waves.

Description

technical field [0001] The invention relates to a fish sex classification method, in particular to a method for identifying male and female of an ultrasonic sturgeon by using the physical function of ultrasound to inspect the early gonads of the sturgeon and judging according to the echogram generated during the ultrasonic inspection of the sturgeon. Background technique [0002] Ultrasonic technology has been very popular and has been applied in various industries such as steel, textiles, printing and dyeing, automobiles, and geology, and has also been widely used in fish management. [0003] For example, a portable ultrasonic fish detector with patent No. 200320125233.1, an ultrasonic fish detector with patent No. 200620074320.2 and an ultrasonic fish detector with patent No. 200620074320.2 are all suitable for measuring targets in water. The location, size and quantity of the fish school, as well as the water temperature and the state of the bottom of the water, etc. [...
