Problems solved by technology

However, although the anti-fragment sheet in this method can make swimming crabs concealed and reduce mutual killing, the anti-fragment sheet is more expensive, and the breeding cost is higher, and it cannot fundamentally avoid mutual killing between individuals, and the breeding survival rate is low

Abstract

The invention provides a method for culturing portunid in a pond. The method comprises the following steps: sterilizing the pond, sun-drying the pond, then flushing the pond, and introducing water into the pond; putting crab seeds into the pond with the stocking density of 2500-3200 per mu and the daily exchanged water quantity of 20-40cm, and oxygenating to the surface and bottom of the pond; and adding a feed composition containing tubificidae, water flea, vitamin C, vitamin E, kieselguhr, zeolite powder, spirulina powder and phytase, stocking crab seeds for 20 days, and regulating and controlling the water quality by use of a traditional Chinese medicine liquid, wherein the traditional Chinese medicine liquid is prepared from the following ingredients: radices sileris, Clerodendrum bungei herbs, caulis londicerae, violet magnolia, walnut leaves, giant knot weed, antifebrile dichroa and chitosan oligosaccharide. Compared with the prior art, the method has the characteristics that not only is the feed composition added into the pond, but also the traditional Chinese medicine liquid is added, and various ingredients achieve a synergistic effect and a mutual promotion effect, so that the technical effects of favorably promoting growth and improving the immunity are achieved, and the survival rate and yield of portunid are improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating swimming crabs in ponds. Background technique [0002] Swimming crab, also known as Portunus trituberculatus, belongs to Crustacea, Decapodidae, and Portunidae. It is an important economic crab in my country's coastal areas. It is widely distributed in China, Japan, North Korea and other sea areas. my country's portunus trituberculatus is mostly produced in the Yellow Sea, Bohai Sea and East China Sea. The East China Sea has the largest amount of natural resources. Swimming crab is rich in nutrition and has a unique taste. It is regarded as top-grade seafood and is favored by people. It is very popular in domestic and foreign markets. [0003] Swimming crabs grow rapidly and are highly profitable in breeding, and have become an important cultured species in coastal areas of my country. Swimming crabs generally live and reproduce at a depth of 3-5 met...
