Embodiment Construction

[0039] The present invention is a kind of pond natural ecological cultivation method of portunus crab, comprises the following steps:

[0040] (1) Setting of breeding ponds

[0041] Swimming crab breeding ponds are preferably sandy and silt, and the bottom of the muddy pond is slightly worse. The area is preferably 10-25 mu. Small-area breeding ponds are easy to manage. The water depth is 1.5-2.0 meters, and the water inlet and drainage are convenient. There is a certain inclination toward the drain outlet, and the inclination angle is between 1°-5°. It is better to completely drain the pool water, and it is better to have central sewage discharge conditions. In order to provide a good habitat for swimming crabs, it is best to spread a layer of 10cm of coarse sand on the bottom of the pool if possible, for swimming crabs to lurk and reduce self-harm.

[0042] Set up a strip fish pond on both sides of the swimming crab breeding pond. One side of the fish pond and the side of t...

Abstract

The invention discloses a pond natural ecological cultivation method of swimming crabs. Including the setting of aquaculture ponds, preliminary preparations for aquaculture, placement of aquaculture seedlings, treatment in the middle and late stages of aquaculture, daily management of ponds, and fishing processes, among which aquaculture seedlings also include stocking of shellfish seedlings and portunus aquaculture. Stocking of swimming crab seedlings, grass carp and shrimp seedlings in the pond. The present invention adopts multi-culture pond multi-species culture mode, and adopts connected symbiotic water system to improve the ecological recycling of nutrients in the water system; and, according to the growth process of swimming crabs, gradually add cultured crayfish and grass carp after they are dead. Swimming crab breeding ponds are used as food to improve the growth vitality of swimming crabs, increase the growth rate of swimming crabs, and reduce disease and death.

Description

technical field [0001] The invention belongs to the technical field of aquatic product cultivation, and in particular relates to a natural ecological cultivation method of swimming crabs in ponds. Background technique [0002] Swimming crabs are widely distributed along the coast of my country, and belong to large-scale marine economic crabs. Their meat is delicious, people like to eat them, and they have high economic value. Because of its fast growth, strong adaptability and less disease, it is suitable for mariculture in coastal ponds. In recent years, it has become a new bright spot in coastal pond cultivation in my country. In nature, swimming crabs grow in shallow seas near the sea, inhabit sea areas with a water depth of 10 meters to 50 meters, and the populations are densest in sea areas with silt bottoms of 10 meters to 30 meters. Swimming crabs are afraid of strong light, and they often hide on the bottom of the sea during the day, and swim to the water layer to l...
