Polyodontidae fry breeding device

Abstract

The invention discloses a polyodontidae fry breeding device, which is composed of a cylindrical placenta isolating pond, a motor, a mixer, a motor front and back direction controller, a first linkingpipe, a spawn incubation pond, a constant temperature pond, a second linking pipe, a first filter, a first water pump, a first water guide pipe, a second water pump, a second water guide pipe, a temperature control meter, a heating pipe, a temperature probe, a third link pipe, and a fry breeding slot. The polyodontidae fry breeding device can rapidly separate and demould the placenta of the wholepolyodontidae and form a single spawn without hurting the unshelled spawn; the spawn is cultivated under the best temperature and environment, the fry cultivating cycle is short, and the fry hatchingspeed is over one-time faster than that of the traditional method; besides, the fry quality is good. When the fry is bred by the polyodontidae fry breeding device, the polyodontidae fry breeding device with high degree of automation has the advantages of greatly reducing the labor intensity, reducing the fry malformation and improving the unshelling rate and the hatching rate.

Description

technical field [0001] The invention belongs to a fish fry breeding equipment, in particular to a spoon kissed sturgeon fry breeding device. Background technique [0002] Spoon-kissed sturgeon, also known as duck-bill fish, belongs to the family Acipenseridae and is a rare large-scale freshwater economic fish in North America. The meat of the spoon-kissed sturgeon is delicious, the snout is rich in collagen, and it is rich in nutrition. It is a delicacy for banquets. Carrying out artificial breeding of sturgeon is of great significance to promoting fishery efficiency and fishermen's income, building a resource-saving and environment-friendly modern fishery, and realizing poverty alleviation through science and technology in the fishery industry. [0003] Spoon-nose sturgeon has seven excellent economic traits: [0004] 1. Wide temperature range. Spoon-nose sturgeon is a euthermic fish. It is not afraid of low temperatures. Even if the water surface freezes, as long as t...

Problems solved by technology

A little negligence will cause a large number of seedlings to die, directly affecting the entire breeding production.

[0021] In my country, most of the sturgeon fry are propagated artificially and unscientifically, and the bred fry have disadvantages such as poor disease resistance, slow growth, uneven individuals, high deformity rate, and large color difference of the original species.

As a result, it brings great risks and low benefits to the farmers of the spoon-kissed sturgeon
