Problems solved by technology

[0003] The technical problem to be solved by the present invention is: the fish egg hatching facilities in the prior art have high requirements on water volume, need sufficient water source, and consume a lot of water; among them, the hatching circuit pool has a large scale, high construction cost, and is not easy to move; among them The hatching tanks consume a lot of water, especially when the season is out of season, it wastes a lot of energy to adjust the temperature of the water body, and the continuous tumbling makes the fish eggs continue to collide with each other, resulting in a large part of the eggs dying due to the collision, and some of them will die. produce deformity

Abstract

The invention relates to a pulse water diversion type fish roe hatching device. The device comprises a water tank (7), wherein a channel assembly higher than the water tank is arranged in the middle of the water tank (7) and comprises a water inlet channel located in the middle and water diversion channels (6) located in two sides, the water inlet channel is communicated with the water diversion channels (6) through water diversion ports (2) in the upper portions of shared side faces, and a main water inlet (1) is formed in the water inlet channel; a water distribution plate (10) is arranged in the water tank, and a hatching frame (4) is placed on the water distribution plate (10); the upper end of each siphon (3) is arranged in the corresponding water diversion channel (6) and downwards penetrates through the water distribution plate (10), and the tail end of each siphon (3) is located under the hatching frame (4); the upper end of each siphon (3) is in the shape of or similar to the shape of an arc which is bent downwards; the side face of the upper portion of the hatching frame (4) is communicated with an overflow channel (9) through an overflow port, the overflow channel (9) is provided with a water outlet pipe (5), and the water outlet pipe (5) allows water and fry to flow out.

Description

technical field [0001] The invention relates to a pulse water distribution type fish egg hatching device, which belongs to the technical field of fish egg hatching devices. Background technique [0002] At present, fish egg hatching in the aquaculture industry generally adopts methods such as loop ponds or hatching buckets. However, these two hatching facilities have higher requirements on water volume and need sufficient water sources. Moreover, the general construction site of the hatching ring pond is large in scale and the construction cost is high, but it is not easy to move, and is not suitable for the hatching of fish eggs in modern industrialized farming. In production practice, the use of hatching buckets for hatching consumes a lot of water, especially when the temperature of the water body is adjusted during off-season hatching, a lot of energy is wasted, and the continuous tumbling makes the fish eggs continue to collide with each other, resulting in a large par...
