A kind of intermediate stage cultivation method for pond shrimp seedlings

Abstract

The invention provides a middle-stage breeding method for young shrimps in a pond. According to the technical scheme, the middle-stage breeding method is mainly composed of a drainage channel (1), a collecting bag (2), a blow-down valve (3), a dirt suction pipe (4), a dam fixing column (5), a dam (6), a water inlet channel (7), a water inlet pipe (8), a water changing valve (9), breeding sheds (10), a pond bottom fixing column (11), the pond (12), an outlet gate (13), an inlet gate (14), a steel frame (15), a plastic zipper (16), a plastic fabric (17), a fixing rod (18), a float bowl cover (19), a float bowl (20) and a self-sticking port (21). Daily temperature rise, bait casting, dirt suction and water change are performed through the separated breeding method, and a water environment and growth demand for shrimp breeding are ensured, so that young shrimps are kept healthy and growing quickly at a certain water temperature. The survival rate and growth speed of the young shrimps are improved, the quality of the shrimps bred in the pond is improved, and larger economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of pond cultivation, in particular to a method for cultivating shrimp seedlings in the middle stage in ponds. Background technique [0002] In pond culture, the production of shrimp per unit area and the quality of economic benefits are related to the survival rate of shrimp seedlings. If the survival rate of shrimp seedlings is high, the yield will be high, otherwise the yield will be low. Due to the high water temperature in the nursery pond, the water temperature in the pond is low when the shrimp seedlings are released, and it is difficult for the shrimp seedlings to eat the bait they are fed in the pond. The main reason for the low level is that at present, shrimp seedlings are temporarily raised in temporary breeding ponds, but due to large investment, high breeding costs, and reasons such as the difficulty of catching shrimp seedlings, they have not been popularized.

Problems solved by technology

Due to the high water temperature in the nursery pond, the water temperature in the pond is low when the shrimp seedlings are released, and it is difficult for the shrimp seedlings to eat the bait they are fed in the pond. The main reason for the low level is that at present, shrimp seedlings are temporarily raised in temporary breeding ponds, but due to large investment, high breeding costs, and difficulty in catching shrimp seedlings, it has not been popularized.
