Embodiment Construction

[0014] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0015] Such as figure 1 As shown, a catfish artificial hatching pond comprises a pond body, a water inlet pipe 1 is opened on the side of the pond body, an air distribution pipe 2 for at least one week is laid on the bottom of the pond body, and the air distribution pipe 2 is connected with an air intake pipe 3 vertical to the bottom of the pond. The bottom of the body is provided with fry collecting pipe 8 downwards, and the upper edge of a relative side wall of the pond body is evenly distributed with hanging rings 4, and each hanging ring 4 is connected with a hook 6, and a hook 6 at the corresponding position of the opposite side wall is articulated. Mesh 5.

[0016] Further, the mouth of the fry collection pipe 8 is plugged with a plug 81 .

[0017] Further, an overflow port 7 is opened on the upper ed...

Abstract

The invention provides an artificial hatching pond for catfish. The artificial hatching pond for catfish comprises a pond body; a water feeding pipe is formed in the side surface of the pond body; at least one cycle of air distribution pipes is paved at the bottom part of the pond body and communicated with an air feeding pipe which is vertical to the bottom of the pond; a fry collecting pipe is downwards formed at the bottom part of the pond body; hanging rings are uniformly dispersed at the upper edges of opposite sidewalls of the pond body; each hanging ring is connected with a hanging hook; a net sheet which divide the pond into two parts is hung on each hanging hook at the corresponding position on the opposite sidewall. With the adoption of the artificial hatching pond for catfish, the hatching rate of catfish can be obviously increased; the survival rate of hatched fries is high; the economic benefit is increased; the artificial hatching pond is worthy of wide popularization.

Description

technical field [0001] The invention relates to the field of catfish reproduction, in particular to an artificial hatching pond for catfish. Background technique [0002] Catfish (Silnrus asotus), commonly known as soil catfish, catfish, year fish, pond horn fish, etc., belongs to Siluriformes Siluridae, is an important freshwater economic fish with wide distribution and high yield in my country. Faster, tender and delicious meat, high market price and large breeding income, etc., has become an important breeding object of freshwater fish farming in my country. Because the key technology of catfish artificial reproduction and some reproductive biology problems related to it have not been well solved and proved, so far, the efficiency of artificial reproduction of catfish is still low. Catfish artificial hatching mostly adopts static water hatching in pond cages or micro-flowing water hatching in hatching ponds, and the hatching rate is low, which needs to be solved urgently....
