Silver Pomfret Fertilized Egg Selection Device and Using Method

Abstract

The invention provides a pampus argenteus fertilized egg selection device. The pampus argenteus fertilized egg selection device comprises a glass reinforced plastic bucket, sticks, screening units, a water pump, a water pipe and a blocking net, wherein the two sticks are arranged on the glass reinforced plastic bucket in parallel in a spaced mode; the two screening units are connected with the two sticks and arranged in the glass reinforced plastic bucket; the water pump is arranged at the bottom of the glass reinforced plastic bucket; one end of the water pipe is connected with the water pump, and the other end of the water pipe is fixed to the upper open end of the glass reinforced plastic bucket; the blocking net is arranged in the glass reinforced plastic bucket and located between the two screening units. By adopting the pampus argenteus fertilized egg selection device and an application method thereof, the situation that fertilized eggs are likely to be damaged due to manual selection is avoided, and the labor cost is greatly lowered; the good-quality fertilized eggs can be effectively separated and selected, the situation that the water quality and the fry growing hatching rate are affected due to the fact that a large number of dead eggs gather in a hatching pond is avoided, the final fry survival rate is guaranteed, and the fry growing efficiency is improved.

Description

technical field [0001] The invention belongs to the field of industrialized fish farming, and in particular relates to a device for selecting fertilized eggs of silver pomfret and a method for using the same. Background technique [0002] Pampus argenteus is the main marine economic fish in the coast of my country, and has a high market demand. However, due to the continuous deterioration of the sea water environment and overfishing, wild silver pomfret resources have shown signs of decline. In recent years, with the continuous improvement of research techniques, it has successfully broken through the bottleneck of its artificial breeding technology. In the process of raising aquatic seedlings, fertilized eggs often need to be screened to remove dead eggs and fertilized eggs with poor quality. At present, artificial breeding of silver pomfret can reach sexual maturity within one year, but the disadvantage is that the development of male and female gonads is poorly synchron...

AI Technical Summary

Problems solved by technology

At present, artificial breeding of silver pomfret can reach sexual maturity within one year, but the disadvantage is that the development of male and female gonads is poorly synchronized, which leads to uneven quality of fertilized eggs, and ultimately leads to a very low survival rate of seedlings
