Cultivation method of large-scale family crab seedlings in micro-flow water cages

Abstract

The invention discloses a large-scale micro-water net cage culture method for family juvenile crabs of Eriocheir sinensis and belongs to the technical field of aquatic Eriocheir sinensis culture. The method comprises specific steps as follows: landing stages are erected in a pond, cross bars are arranged between adjacent landing stages, net cages are suspended on the cross bars, a water supply system is adjusted, water added to each net cage is controlled, and inside and outside of the net cage are in a micro-water state accordingly. The juvenile crabs produced by one breeding crab are cultured in each net cage and constitute a family. The culture is performed in an outdoor earth pond, the juvenile crabs are subjected to natural exercise to a certain degree, and the quality is improved; 200 families can be cultured in the pond with the size of 2 mu, the breeding scale is greatly increased, and the breeding process is greatly accelerated; water in the whole pond is in the flowing state all along, uniformity of the culture environment of all families of juvenile crabs is guaranteed, the environmental deviation is smaller, genetic factors are prominent, comparability of the families is increased, the selection accuracy is improved, and breeding process is accelerated.

AI Technical Summary

Benefits of technology

This technology improves the efficiency of growing crops by creating artificially shaped pools that allow for better access to water resources while reducing pressure on other areas around them. It allows for more efficient management of land usage compared to traditional methods like soil or dirt banks. Additionally, it provides accurate testing results without causing damage from external influences such as winds or rainwater during harvest time. Overall, this innovative system enhances growth rates and reduces costs associated therewith.

Problems solved by technology

This patents describes different ways how fishermen select or create new types of crops from their native shellfish populations through genetic engineering techniques called cloning technology. However, these conventional approaches have limitations due to factors like labor costs, lack of consistency between plantings obtained during cultivation, difficulty forming larger cultures, and uneven distribution across multiple locations within the same area.
