Description
Technical Field
The invention relates to the technical field of agricultural cultivation, in particular to a cultivation method for improving the benefits of crayfishes, river crabs, including 'Liuyuehuang' and freshwater shrimps.
Background
"Liuyuehuang" is the first molting of river crab before mature period in the middle and lower reaches of Yangtze river, and the time is 6 months in lunar calendar, and is the intermediate stage of river crab stepping from "teenager" to "youth". Commonly called as juvenile crab, the weight is generally 75-100 g/crab, and the crab meat has the characteristics of crisp outer shell, soft inner shell, heavy fishy smell and plump meat quality.
In the traditional culture process, the crayfish, the river crab and the freshwater shrimp are cultured in separate ponds or are cultured in a mixed mode together, if the separate ponds are adopted for culture, the area of a pond is large, meanwhile, the pond has a long idle period after the crayfish, the river crab or the freshwater shrimp are caught, resources are wasted while the cost is increased, if the mixed culture is adopted, a uniform feed and culture management scheme is adopted, the optimal feed and the optimal culture management scheme are different to a certain degree during the culture of the crayfish, the river crab and the freshwater shrimp, so that the value-added speeds of the crayfish, the river crab and the freshwater shrimp are different from the optimal condition, the culture speed does not reach the maximum, the utilization rate of the feed is reduced, the variety is rich compared with the independent culture, the yield is reduced, and meanwhile, the crayfish is cultured in a mode with the maximum value-added, the yield is reduced, The time for selling river crabs and freshwater shrimps in the market is different, from the market perspective, the breeding progress of crayfishes, river crabs and freshwater shrimps is staggered, different shrimps are sold in different time periods, economic benefits are more easily generated, and the breeding progress of the crayfishes, river crabs and freshwater shrimps is the same due to mixed breeding, so that the economic benefits are reduced.

s81, stocking the seedlings: 10-15kg of freshwater shrimp fries are put and cultured per mu, and the specification is 4000-;
s82, cultivation management: controlling the water plant coverage rate within 20 percent of the area of the pond, feeding the special compound feed for the freshwater shrimps with the protein content of 36 percent, continuously using EM (effective microorganisms) bacteria to adjust the water quality, periodically using a substrate modifier, splashing the special compound feed for the freshwater shrimps in the whole pond by using quicklime water every 10 to 15 days, starting an aerator at regular time, and starting the aerator in time in rainy and muggy weather;
s83, catching the freshwater shrimps: catching freshwater shrimps at the beginning of 12 months till the end of Yuanyue.
2. The cultivation method for improving the efficiency of crayfishes, river crabs, and freshwater shrimps as claimed in claim 1, which is characterized in that: in step S1, the pond selection requirements are: the area is 30 mu, the east-west trend, the pond keeps the water depth of 1.0-1.2m, the water surface of the field can keep 40-50cm, the water source is sufficient, the water quality is good, and no pollution source exists around. The breeding pond is divided into two halves by a net sheet, or in a sakaguchi area, 30-40% of the area of the pond is enclosed by a purse net.
