| titleOfInvention | Specific pathogen-free seedling cultivation method for portunus trituberculatus |
| abstract | The invention discloses a method for culturing non-specific pathogen seedlings of portunus trituberculatus, which belongs to the field of aquaculture, and comprises the steps of collecting young portunus trituberculatus VI, temporarily culturing in an indoor cement pond, and numbering at the cephalothorax part; and then detecting common viruses of the portunids, and transferring the common viruses into a plastic box for independent culture. 1:1 pairing female and male crabs, transferring the paired female and male crabs into 1 plastic box, and carrying out copulation and fattening; and in the middle ten days of the month 11, common virus detection is carried out on the copulated female crabs, and the copulated female crabs enter an overwintering pool. Performing parent crab intensive cultivation and common virus detection in 3 months of the next year, and entering a nursery pond; feeding controllable bait during seedling raising; adjusting water quality, and changing water in the seedling process; and (4) the seedlings reach the commodity specification, common viruses are detected by sampling, and the seedlings in the seedling raising pool with the positive rate less than 2% enter the market. The invention realizes the SPF (specific pathogen free) offspring seed production of the portunus trituberculatus, the offspring seed yield is averagely improved by 27.5 percent, and the breeding survival rate is averagely improved by 30.29 percent; the water for seedling culture is reduced by 200 percent. |
