Description

Fry adhering net device before hatching and smoothing of carp

Technical Field

The utility model relates to the technical field of aquatic incubation equipment, in particular to a fry attaching net device before carp incubation and swimming.

Background

At present, in the natural hatching process of carps, the fingerlings just broken through the membrane cannot be completely absorbed due to yolk, and the fingerlings cannot grow large enough and cannot float, so that the carps cannot swim completely and eat independently. The fish fry needs to find a sufficient dissolved oxygen space, and continue to develop on the fish fry until the egg yolk absorbs and grows a large enough swimming bladder, so that the fish fry can not swim freely and eat, and the fish fry enters the parallel swimming stage. In the mode of simulating natural hatching, the artificial hatching of the carps generally adopts a mode of suspending egg slices. The fish eggs in the egg slices are hatched into fish fries firstly, and then the fish fries are attached to the egg slices to continue to develop to the flat-swimming stage. The egg slices are easy to pollute and mildew so as to influence the hatchability of the fries, and the spawns can not be supplied to the fries for adhesion after mildew. In the improved loop hatching mode, egg pieces are not attached to the loop, fish eggs need to float along with water flow in the loop after membrane rupture, but fish fries are fragile, and the fish fries are easy to injure and die when rotating and floating in the loop.
