Description

Hatching apparatus of fish embryonated egg

Technical Field

The utility model relates to a fish fertilization hatching technology, in particular to a hatching device for fish fertilized eggs.

Background

Fertilized fish eggs are classified into three types, viscous, semi-viscous and non-viscous. The artificial hatching mode comprises hatching with nests and hatching with running water. Currently, non-adhesive eggs and fertilized eggs after debonding need to be incubated in running water in order to avoid accumulation and death. The sticky eggs with nests are generally hung in a water pool for direct hatching. The hatching equipment comprises a hatching loop, a hatching cylinder and the like, and if the hatching of the four Chinese carps is large in batch, the former can be adopted, and the latter can be adopted if the hatching is small in batch.

The incubation loop construction occupies large area, has high cost and uneven water flow, and is easy to accumulate dead eggs; the hatching jar or the hatching barrel generates water flow at the bottom of the hatching jar or the hatching barrel, and fertilized eggs are overturned in water under the action of the support. The two devices have the disadvantages that the water flow cannot be stopped, particularly, the newly hatched fry is tender and weak, the buoyancy is reduced due to the removal of the egg membrane, and the water flow needs to be increased. In the hatching process, the phenomena of embryo damage and hatching failure are easily caused.

The adhesive fertilized eggs with nests are generally hung in outdoor ponds or cement ponds in greenhouses. If outdoor conditions change, a large number of dead eggs often occur; if the fry are in a cement pond in a greenhouse, the fry are easy to pile up and die after being deciduated and fall behind the water bottom.
