Zusammenfassung: | The invention relates to the technical field of aquaculture, in particular to a method for breeding high-quality anti-season commercial crabs by utilizing low-value female parents obtained after emergence of juvenile eriocheir sinensis. The method comprises the steps of (1) construction of an indoor temperature-control temporary breeding pond; (2) selection, transportation and disinfection of temporarily-bred crabs; (3) desalination in different levels in the early period; (4) ecological fattening in the later period; (5) fishing and selling on the market. The method is mainly based on reproduction biology and ecological breeding science of eriocheir sinensis, and the indoor temperature-control temporary breeding pond is utilized for providing a relatively stable and superior breeding environment for physical power recovery, secondary spawning and secondary development of ovaries of the eriocheir sinensis after emergence of the juvenile eriocheir sinensis. The method greatly improves the economic value of bre |
