Abstract

The invention relates to a fry collecting device and fry collecting method for fry raising of cherax quadricarinatus. The fry collecting device comprises a plurality of PVC pipe bodies, a bottom sealing mesh, a connecting rope and a float, wherein the PVC pipe bodies are in parallel arrangement and are connected into a string through the connecting rope, and the float is arranged at one end of theconnecting rope; and each PVC pipe body is prepared by enabling PVC pipes to be stuck, and the bottom sealing mesh is adhered to one ends of the PVC pipe bodies. The fry collecting device is arrangedin a culture pond to provide a shelling and shielding place for cherax quadricarinatus fries, concentrated breeding of cherax quadricarinatus fries is convenient, the cherax quadricarinatus fry collecting efficiency when the cherax quadricarinatus fries are cultured in ponds is improved, and the disability rate of the cherax quadricarinatus fries is reduced. The fry collecting device is simple intechnology, and convenient to make, transport and store, and the cherax quadricarinatus fry collecting efficacy can be improved by 10% or above.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a red-clawed crayfish breeding facility, in particular to a seedling picking device and a seedling-picking method for raising red-clawed crayfish seedlings. Background technique [0002] Commonly known as Australian freshwater lobster, red claw crayfish has the characteristics of fast growth, miscellaneous food habits, strong adaptability, easy breeding and transportation, etc. Its tender meat and delicious taste are deeply loved by consumers. Red-clawed crayfish likes to live in hidden places at the bottom of the water, and the collection efficiency of shrimp seedlings is low. Before the present invention, earthen ponds cultivated red-clawed crayfish seedlings were mostly collected by hanging a single string of mesh to reduce the injury of collecting shrimp seedlings by fishing in earthen ponds. residual rate and improve the collection efficiency of shrimp fry, but the effect ...
