Sturgeon artificial spawning operating table

Abstract

A sturgeon artificial spawning operating table is characterized by comprising a bracket (1) and a sturgeon operating frame (4). A collar (2) is fixed at one end of the bracket (1), and the other end of the bracket (1) is provided with a sleeve (3) in the offset mode. The sturgeon operating frame (4) consists of a T-shaped main rod (5), two upper struts (6) identical in structure and a plurality ofcurved connecting rods (7) connecting the two upper struts (6) and the T-shaped main rod (5) to form a fish-shaped structure capable of accommodating the sturgeon body. The straight end of the T-shaped main rod (5) is inserted into the collar (2), and one side of a cross rod of the T-shaped main rod (5) is inserted into the sleeve (3). The operating table solves the spawning problem in the artificial propagation process of the Chinese sturgeon, lays a foundation for the artificial propagation of the Chinese sturgeon and can ensure the 100% survival rate of the Chinese sturgeon after spawning,which is beneficial to the continuation of the population. At the same time, the operating table has the advantages of simple structure and convenient operation and use.

Description

technical field [0001] The invention relates to an aquaculture technology, in particular to an egg retrieval technology used in the Chinese sturgeon culture technology, in particular to an operating table for artificially induced spawning of sturgeon. Background technique [0002] Chinese sturgeon (scientific name: Acipenser sinensis) has an average body length of about 40 cm, a maximum length of 130 cm, and a maximum weight of 600 kg. The body is spindle-shaped, the head is pointed and the snout is long, and there are 4 snout barbels in front of the mouth. Two rows on each side. Sturgeon is a rare ancient fish left over from the Mesozoic Era 150 million years ago. It is between cartilage and hard bone. The degree of ossification of the skeleton generally decreases. Most of the cranial cartilage shell is not ossified. The caudal fin is crooked, the even fin has a broad base, and the dorsal and anal fins are opposite. The pelvic fin is located in front of the dorsal fin, ...

Problems solved by technology

[0024] The purpose of the present invention is to adopt traumatic method to make the sturgeon survival rate after the ovum extraction is not high for existing Chinese sturgeon ovum extraction, influences the problem of population continuation, designs a kind of adopting extrusion method to extract ovum, after ovum extraction, can Sturgeon artificial induction operating table that can return the sturgeon to the breeding pond and wait for the eggs to be retrieved in the next year, and can be repeatedly retrieved
