High-yield and high-efficiency pond culture technique for Chinese prawns

Abstract

The invention discloses a high-yield and high-efficiency pond culture technique for Chinese prawns, which is characterized by comprising the following steps: in winter, after the prawns are borne, drying a pond and cleaning out 10 to 20 centimeters of silting soil on the bottom surface of the pond; in mid-February, performing pond soaking and performing disinfection with biological medicaments; in mid-March, filling water into the pond in which the water depth is required to be between 1.2 to 1.5 meters; after filling water, performing water fertilization with 0.5 kilogram of diammonium phosphate for per mu of the water, forming living organism baits by adopting photosynthetic bacteria and algae reproduction, and controlling the salinity to be between 2 to 3 percent and the pH value to be between 7 and 8.6; releasing prawn postlarvae before or after the May Day; and after releasing the prawn postlarvae, adopting a feeding mode of mainly putting in fresh and alive baits of small whelks and secondarily putting in miscellaneous fishes and shrimps and the like, performing the water fertilization once with 0.5 kilogram of the diammonium phosphate for per mu of the water in the middle ten-day of each month, and after the water fertilization, keeping the water in the pond without large-scale output and input, performing a small amount of exchange each ten days, and adding water when the water level is lowered. The high-yield and high-efficiency pond culture technique solves the problems that the pond culture of the Chinese prawns has low yield, high disease incidence and poor benefits, and is suitable for the high-yield and high-efficiency pond culture of the Chinese prawns.

Description

Technical field [0001] The invention relates to the field of aquaculture, in particular to a high-yield and high-efficiency pond culture technique for Chinese shrimp. Background technique [0002] At present, the production of Chinese prawn pond culture is low, the incidence rate is high, and the benefit is poor. Summary of the invention [0003] In order to solve the problems of low yield, high morbidity and poor benefit of Chinese shrimp pond culture, the invention invents a high-yield and high-efficiency pond culture technology. [0004] In order to solve the above-mentioned technical problems, the present invention adopts a technical scheme that is a high-yield and high-efficiency pond culture technique for Penaeus chinensis. Its special features are: [0005] 1. Clean the pond: After the shrimps emerge in the winter, they are dried in the pond, and the silt on the bottom of the pond is removed by 10-20 cm; [0006] 2. Bubble pool: enter the bubble pool in mid-February and conduct...
