Artificial shallow water breeding method for freshwater shrimps

Abstract

Provided is an artificial shallow water breeding method for freshwater shrimps. The artificial shallow water breeding method for the freshwater shrimps comprises the step of building a pond, wherein the shallow pond of 5-10 acres is selected, the depth of water inside the shallow pond is smaller than 1.5 meters, and a trough shaped like a Chinese character 'shi' or 'jing' is dug in the middle of the pond; the step of sterilizing the pond, wherein the breeding pond is exposed in the sun for 1-2 weeks from late July to early August before shrimp seedlings are put into the pond, then water is injected, and the water in the breeding pond is sterilized through quick lime disinfectants; the step of breeding trying, wherein the water is discharged and the shrimp seedlings are put into the pond after 8-12 days of sterilization, and if the shrimp seedlings are normal after 24 hours of breeding trying, the shrimp can be bred in a large scale; the step of breeding, high-quality and healthy shrimp seedlings of 7000-8000 per kilogram are selected to be bred; the step of daily management, wherein an oxygen increasing pump is arranged every 3-5 acres, and chlorine dioxide disinfectants are utilized for preventing diseases at a time monthly; the step of fodder feeding, wherein after the shrimp seedlings are bred, compound fodder for the freshwater shrimps is fed once every evening, after 15 days, the compound fodder is fed once every morning and evening, the feeding amount at a time accounts for 3-5% of weight of the freshwater shrimps, and the fodder is fed until the finished freshwater shrimps are harvested and come into the market.

Description

technical field [0001] The invention relates to a shallow-water artificial culture method for freshwater shrimp, which belongs to the technical field of shrimp culture in ponds. Background technique [0002] Freshwater shrimp is also known as river shrimp. The cultivation technology of freshwater shrimp belongs to relatively mature artificial breeding technology, especially the pond cultivation of freshwater shrimp is the most; the cultivation technology of freshwater shrimp not only refers to pure freshwater shrimp cultivation, but also includes mixed with other species. For example, one or more kinds of polyculture with other fish species or soft-shelled turtle species; however, the techniques of pure culture or polyculture are different due to the different breeding habits of different species, so farmers adopt specific breeding methods to improve breeding efficiency There are also differences. At present, the pond culture technology of freshwater shrimp mainly includes:...

AI Technical Summary

Problems solved by technology

At present, the pond culture technology of freshwater shrimp mainly includes: pond selection, pond cleaning, reasonable stocking, scientific baiting, and daily management, among which the selected pond size and water depth have certain requirements. The water depth is too shallow, and the change of water temperature is greatly affected by the environment. According to the habits of freshwater shrimp, the large temperature difference in water temperature will easily cause the death of freshwater shrimp. , especially in early spring and winter, the temperature difference changes greatly, and the mortality rate of freshwater shrimp in batches increases greatly, thereby reducing the harvest rate of finished shrimp, increasing the breeding cost of freshwater shrimp, and the breeding efficiency is not high enough

Of course, if you want to dig deep shallow ponds, first, you will be limited by the current situation of the pond, if you can’t dig deeper, such as rice fields as aquaculture ponds, etc.; second, digging deeper ponds will significantly increase the cost of aquaculture
