TECHNICAL FIELD

[0001] The utility model belongs to the rice field crayfish breeding technical field, concretely relates to a kind of shrimplets screening device for rice field breeding crayfish. BACKGROUND

[0002] Rice field breeding crayfish often needs to screen new shrimplets to be put into breeding field, and screening shrimplets can ensure the selection of healthy and high-energy individuals, which are less likely to be affected by diseases during growth, thereby improving overall survival rate and breeding efficiency.In addition, regular screening of new shrimplets can avoid inbreeding and maintain the quality of shrimp breeding.

[0003] Currently, there are many ways to screen shrimplets, but many of them use grilles and screens to screen larger shrimplets.However, shrimplet screening is not only based on size, but also on activity, and some healthy shrimplets have higher activity and stronger adaptability to new environments, resulting in higher survival rate.However, there are few specific devices for shrimplet activity screening, and various methods are generally used to screen shrimplet activity, one of which is the reverse water experiment, which involves stirring the water in a bucket or basin, then placing a batch of shrimplets in it, and the vortex water flow generated during stirring acts on the shrimplets.Some shrimplets with high activity will instinctively swim against the water and quickly escape the vortex water flow center to the edge area with weaker water flow, but some shrimplets with low activity or dead shrimplets cannot escape the vortex water flow and will be driven to the vortex center area, thereby achieving the purpose of screening shrimplets with high activity.However, manual stirring of water flow is not stable and sustainable, and shrimplets that escape the vortex water flow cannot be collected in time, so we propose a shrimplet screening device for rice field breeding crayfish, which can specifically and targetedly conduct reverse water experiment on shrimplets to help breeders better and faster screen and collect shrimplets with high activity.
