Method for promoting portunus trituberculatus females to quickly develop roe

The invention provides a method for promoting portunus trituberculatus females to quickly develop roe. The method comprises the following steps of: preparation of a roe-growing pond, selection and stocking of the females, breeding environment conditions, preparation of baits, daily management and catching and selling. According to the development law of the ovary of the portunus trituberculatus, good environment conditions are artificially created, and good-quality baits are used to feed the portunus trituberculatus, so that the ovary of the portunus trituberculatus is quickly developed, and the nutritious value and the edible value of the portunus trituberculatus are improved. The key points of the method include: the proper temperature is between 18 and 25 DEG C, the proper salt content is 25 to 35ppt, the sand is paved on the bottom of the pond, microporous oxygen-supplying tubes are arranged so as to supply oxygen to the bottom part, and the compound feed and living baits are alternately fed. Through nearly 60 days of quick roe development, the roe weight index of the portunus trituberculatus is increased from original about 1 percent to over 7 percent, the red roe rate and the survival rate are about 70 percent and 80 percent respectively, and the nutritious value and the economic value of the females are improved. The method is suitable to be used by portunus trituberculatus breeding enterprises, portunus trituberculatus catching units and fishmen and contributes to protection and reasonable utilization of wild resources of the portunus trituberculatus.
