Breeding method of penaeus vannamei

Abstract

The invention discloses a breeding method of penaeus vannamei. The method includes the following steps of 1, construction of a breeding pond, wherein the middle of the breeding pond is provided with awater blocking plate to divide the breeding pond into a left part and a right part; 2, construction of an oxygen supply system, wherein the oxygen supply system includes an aerator in the pond and anoxygen aeration system outside the pond, the aerator in the pond is arranged in the breeding pond, the oxygen aeration system outside the pond includes a coiler, a water pump and a lamp tube, a waterinlet of the coiler is connected with the water pump, the water pump pumps water in the breeding pond into the coiler, and the lamp tube is arranged aside the coiler; 3, sterilization of the breedingpond; 4, breeding of microorganisms serving as baits, wherein allicin and a chlorella growth accelerant are added into the breeding pond, and then chlorella is raised in the breeding pond; 5, stocking and management of shrimp seeds, wherein healthy shrimp seeds of penaeus vannamei are selected, the oxygen supply system is started according to the concentration of dissolved oxygen, and the shrimpsare constantly bred till the shrimps grow up. The breeding method has the advantage that the concentration of the dissolved oxygen is maintained stable for a long time.

Description

technical field [0001] The invention relates to the technical field of aquaculture. More specifically, the present invention relates to a culture method of Penaeus vannamei. Background technique [0002] Penaeus vannamei is one of the three high-quality varieties with the highest aquaculture output in my country. Its shell is thin, its normal body color is blue, and there are no markings on the whole body. Penaeus vannamei is omnivorous and has three characteristics: strong adaptability, fast growth, and strong disease resistance. It can grow as long as the protein ratio in the bait accounts for more than 20%; it has delicious meat, high meat yield, and wide-salinity. , High temperature resistance, its seedlings can grow into adults after more than 100 days of cultivation, and the body length can reach 24cm. Shrimp farming is a high-input, high-yield industry. In order to pursue a higher growth rate of Penaeus vannamei, farmers often overfeed feed. When it is cloudy or at ...

AI Technical Summary

Problems solved by technology

Shrimp farming is a high-input, high-yield industry. In order to pursue a higher growth rate of Penaeus vannamei, farmers often overfeed feed. When it is cloudy or at night, algae cannot perform photosynthesis and release oxygen, resulting in water quality problems. The lack of oxygen deteriorates, which in turn leads to many diseases of prawns. Even though Penaeus vannamei has strong disease resistance, it still faces serious shrimp diseases, which seriously hinders the survival and development of the prawn farming industry.
