Problems solved by technology

However, most of the shrimps currently on the market are self-breeding and self-cultivating by farmers, and the species degradation is serious. Therefore, the growth rate is not fast, the market size is small, and the economic value is not high. At the same time, the stocking density is high and the production process The lack of unified technical standards for control directly affects the sustainable and stable development of the shrimp farming industry

Embodiment Construction

[0012] Take the cultivation of Yangtze River freshwater shrimp as an example:

[0013] In March every year, high-quality Yangtze River freshwater shrimp species with large specifications, strong vitality, no pests and diseases, and complete steps are selected, and 60,000 to 80,000 shrimp species per mu are released. When raising seedlings, the area of ​​the seedling pond is 0.5-2 mu, the water depth is 1-1.5 meters, the water inlet and drainage are convenient, and the water source is sufficient and pollution-free. Use 150 kg / mu of quicklime, or chlorine preparations or tea seed cakes to clear the ponds, with an amount of 1-2PPM, to disinfect the ponds. This is a very important step in breeding, which is related to the survival rate of shrimp seedlings. The pond area for cultivating broodstock is 8-12 mu, the water depth is 1.3-1.5 meters, the bottom is silt and sand, and the silt does not exceed 20 cm; within 15 days after the shrimp seedlings enter the pond, they are fed with...

Abstract

The invention discloses a novel Yangtze River shrimp culture method. Yangtze River shrimps are cultured by the aid of natural Yangtze River water, different natural baits are respectively thrown in different growing periods of the Yangtze River shrimps, natural water temperature is adopted during winter greenhouse culture, and the water is not heated. Compared with an existing Yangtze River shrimp culture method, the novel Yangtze River shrimp culture method has the advantage that the cultured Yangtze River shrimps are long in growing period and closer to wild Yangtze River shrimps, so that original ecological natural Yangtze River shrimps with delicious taste, large specifications, high growth speed, low morbidity, fine plumpness, sturdiness, compact meat, heavy individual weight and high in-season rate are cultured.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating Yangtze River shrimp. Background technique [0002] Yangtze River Shrimp is a freshwater shrimp species with strong adaptability, low temperature resistance, miscellaneous food habits, and nocturnal activities. Compared with ordinary shrimps, Yangtze River shrimps are large in size, thin in shell, tender in meat, rich in nutrition, and high in economic value. However, most of the shrimps currently on the market are self-breeding and self-cultivating by farmers, and the species degradation is serious. Therefore, the growth rate is not fast, the market size is small, and the economic value is not high. At the same time, the stocking density is high and the production process The lack of unified technical standards for control directly affects the sustainable and stable development of the shrimp farming industry. Contents of the invention [0003] Th...
