Description
Technical Field
The utility model relates to the technical field of aquatic hatching equipment, in particular to a device for separating a carp water mould egg from an egg skin.
Background
At present, in the hatching process of carps, loop hatching is generally adopted, and the process comprises four steps of spawning in a fish pond, shoveling eggs at the bottom of the pond, twisting egg masses and loop hatching. In the spawning process of the fish pond, the fertilized rate of the fish eggs is large, the unfertilized rate is at least 2%, and the unfertilized rate can be up to more than 40%. In the process of shoveling eggs at the bottom of the pool, many fish eggs can be injured or shoveled to form dead eggs and empty egg skins. The egg mass under the shovel needs to be rubbed into single grains or tiny lumps to ensure oxygen supply. The rubbed eggs can damage part of the fish eggs, and the produced dead eggs and egg skins can not be screened out, so that the rubbed fish eggs can carry the dead eggs and egg skins and put the fish eggs and egg skins into a loop for hatching. When fertilization rates are low, the dead eggs gradually mould to form hydromyces eggs, which fill the entire loop and block the barrier net, eventually leading to water quality deterioration and failure of hatching.

The device is used in the process of:
firstly, the cone bottom of the egg gathering cone 201 and the water inlet rectifying cone 102 form a diversion surface, so that the water flow in the suspending pontoon 202 uniformly turns in the egg gathering cone 201 when moving downwards, and continuously moves upwards under the action of the water inlet flow, and the water flow turns in the upper part of the suspending pontoon to form circulating water flow, which makes the circulating water flow slow and uniform, and does not generate turbulent flow so that the fish eggs can stably suspend in the suspending pontoon 202. Because the pontoon 202 is of a suitable length, the top end of the circulating water does not pass over the pontoon 202, and thus the eggs of fish in the circulating water do not drift out past the pontoon 202. The sedimentation cone 203 at the upper part of the suspension buoy 202, because the conicity of the sedimentation cone 203 is larger and longer, when discharged water flow enters the sedimentation cone 203 from the suspension buoy 202, the flow velocity of the discharged water flow is gradually reduced because the diameter of the water body is gradually increased, so that the water flow force is gradually reduced, and the roe is not taken away, so that the roe sedimentation effect is realized.
