Indoor prawn stereoscopic graded cultivation device and cultivation technology of same

Abstract

The invention provides an indoor prawn stereoscopic graded cultivation device and a cultivation technology of the same. The cultivation technology comprises the steps that an inner cultivation pond and an outer cultivation pond are provided, wherein the inner cultivation pond and the outer cultivation pond are processed and manufactured by food-grade plastic plates; the inner cultivation pond is suspended inside a water body of the outer cultivation pond, and the bottom wall of the inner cultivation pond is equipped with a first opening inlaid by a steel wire gauze and a second opening shielded by a movable cover plate; shrimp seeds are put into the inner cultivation pond to realize screening cultivation, and the screened shrimp seeds are put into the outer cultivation pond to realize growth cultivation; and when prawns in the outer cultivation pond are bred and cultivated, the prawns are harvested by net spooning or entrapment, then the screened shrimp seeds in the inner cultivation pond are moved to the outer cultivation pond by the second opening to realize the growth cultivation, and finally new shrimp seeds are put into the inner cultivation pond to realize screening cultivation.

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
