Indoor three-dimensional grading culture device for prawns and its culture technology

Abstract

The invention provides an indoor three-dimensional grading culturing device for prawns and a cultivating process thereof. The culture process includes the following steps: providing an inner culture pond and an outer culture pond, both of which are made of food-grade plastic plates; suspending the inner culture pond on the In the water body of the outer culture pond, the bottom wall of the inner culture pond is provided with a first opening inlaid with a steel wire mesh and a second opening covered by a movable cover plate; the shrimp seedlings are put into the inner culture pond for standard coarse culture. , put the thickened shrimp seedlings into the outer culture pond for growing; when the prawns in the outer culture pond are grown and cultivated successfully, collect the shrimp by fishing nets or trapping, and then remove the prawns from the inner culture pond. The roughened shrimp seedlings are transferred to the outer culture pond through the second opening for grow-out culture, and finally put new shrimp seedlings into the inner culture pond for standardized roughage culture.

Description

technical field [0001] The invention relates to the technical field of prawn cultivation, in particular to an indoor three-dimensional grading cultivation device for prawns and a cultivation process thereof. Background technique [0002] At present, with the increasing pollution of seawater, the diseases of prawn farming are also becoming more and more serious. The shrimp farming industry has begun to adopt indoor closed circulating water shrimp farming technology in order to provide a safer growth environment for shrimp, thereby increasing the breeding density and survival rate. [0003] The mode that often adopts in the factory culture at present is: 1, build cement breeding pond and water inlet and outlet facilities. 2. Build a cement standard rough pool to standardize the seedlings. 3. Transfer the thick seedlings to the breeding pond during graded cultivation. The purpose of this graded culture is to make the shrimp grow up in a safer environment, so as to increase t...

AI Technical Summary

Problems solved by technology

The motivation is right, but it has not been widely promoted. The important problems are: 1. The investment cost of building cement pools to prevent water leakage for a long time is too high

2. When the shrimp seedlings are raised to a reasonable size in the standard coarse pond and transferred to the pond, the stress of environmental changes is severe, which is not conducive to the continued growth of the shrimp seedlings

3. It is inconvenient to transfer shrimp seedlings from standard coarse ponds to reasonable specifications, and it is difficult to quantify one standard coarse pond to several breeding ponds
