To solve the problems involved in the mass artificial incubation of redclaw crayfish eggs, we developed a recirculating mechanical pulling device to explore the technology of artificial incubation, including the egg stages, egg densities, attachments and incubator sizes. The eggs were separated and sterilized with 3000 ppm formaldehyde, and the water temperature was 28–29°C. The results were obtained:...
