High-yield freshwater shrimp breeding method

Abstract

A high-yield freshwater shrimp breeding method comprises the steps that (a), a pond of 5 to 10 mu is selected, and the depth of water is 1.2-1.8 meters; (b), the pond is prepared and exposed to the sun for 1-2 weeks before freshwater shrimp seeds are bred in the pond from late July to early August, then water is injected in the ponds for 10-15 centimeters, and water in the aquaculture pond is disinfected; (c), the seeds are tested 8-12 days after the water is disinfected to test whether disinfectors after disinfection are completely eliminated; (d), high-quality and healthy shrimp seeds are selected to be bred, and water is injected until the fixed water depth after breeding; (e), daily management is executed, before or after the freshwater shrimp seeds are bred, 3-4 meshes for freshwater shrimps to rest are arranged in the middle of the aquaculture pond, an oxygenation pump is additionally arranged for every 3-5 mu, and after the freshwater shrimp seeds are bred, chlorine dioxide disinfectors are used for preventing diseases once in each of the at least two first months; (f), fodder is fed to the freshwater shrimp seeds, after the freshwater shrimp seeds are bred, mixed fodder with 36%-41% of protein for the freshwater shrimps is provided for the freshwater shrimp seeds for one time at dusk, after 15 days, fodder is provided every morning and evening, and the freshwater shrimps are bred until late September and are caught for selling according to the principle that large freshwater shrimps are caught and small freshwater shrimps are reserved.

Description

technical field [0001] The invention relates to a high-yield culture method for freshwater shrimp, which belongs to the technical field of aquatic artificial culture. Background technique [0002] Freshwater shrimp is also known as river shrimp. The cultivation technology of freshwater shrimp belongs to relatively mature artificial aquaculture technology, especially the pond culture of freshwater shrimp is the most; the cultivation technology of freshwater shrimp not only refers to pure freshwater shrimp cultivation, but also includes the cultivation of freshwater shrimp with other species. Polyculture, such as one or more kinds of polyculture with other fish species or soft-shelled turtle species; however, due to the different breeding habits of different species, the techniques of pure culture or polyculture are different, so in order to improve the breeding efficiency, farmers especially pursue more There are also differences in the specific farming methods adopted to ach...
