Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the fertilized eggs and larvae of fishes of the sturgeon family cannot survive in the muddy water body, the artificial breeding of sturgeons requires a large investment in the early stage of the facilities, and the fish fry are in a critical period of development due to environmental changes leading to growth. Stagnation or even a large number of deaths, a muddy water breeding device for sturgeons was proposed

Abstract

The invention provides a breeding device of sturgeons in argillaceous body and relates to a breeding device. The invention aims at solving the problems that the fertilized eggs and larvae with ruptured membranes of sturgeons can not live in argillaceous water body, the upfront investment in facilities is great in breeding sturgeons artificially, and growth retardation and even mass mortality caused by the change of the environment in the critical breeding period of the fish fry exist. The two sides of each first mono-layered filter screen are fixedly connected with two panel bodies respectively; the double-layered filter screen is fixedly connected with the bottom part of the two panel bodies; one side of each side air bag waterproof bag is connected with the bottom air bag waterproof bag through a plurality of extensible belts; the external side of each panel body is provided with a side air bag; the bottom air bag is fixed on the bottom part of the double-layered filter screen; an air pump is respectively communicated with the side air bag gas tube and the bottom air bag gas tube; the branched passage of each side air bag is communicated with a group of first branch pipes which are installed in the inner container of the side air bag; the gas tube of the bottom air bag is communicated with a group of second branch pipes which are installed in the inner container of the bottom air bag; and the inner container of the air bag is provided with a group of gas needles. The invention is used for breeding sturgeons.

Description

technical field [0001] The invention relates to a fish breeding device. Background technique [0002] Sturgeon eggs are large, sinking eggs that are mostly laid by sexually mature female sturgeon in natural spawning grounds under natural conditions. The spawning grounds are located in the upper reaches of rivers, where the water quality is clear, the water is slow and sandy. The fertilized eggs of the artificial breeding sturgeon are all under controllable flowing water conditions. The main principle is to use the kinetic or potential energy of the water to drive the debonded fertilized eggs of the sturgeon to turn up and down to reduce the stickiness of the fish eggs during the hatching process; the main incubators such as Russia (former Soviet Union) Yushchenko incubator, Sturgeon No. 1 incubator, Atkin incubator, American McDonnell incubator and Chinese trough incubator (screen type, shower type or tipping bucket type), bottle incubator, etc. The development of larvae is...
