Culture method for freshwater shrimp and soft-shelled turtle polyculture

Abstract

The invention belongs to the technical field of agricultural culture, and particularly relates to a culture method for freshwater shrimp and soft-shelled turtle polyculture. A culture pond is 1.5 m deep, multiple movable inverted-A type nets are arranged in the polyculture pond, and Sibin stone needle is put into the closed part of the inverted-A structure. Compared with the prior art, the culture method has the advantages that the inverted-A type nets can be arranged, soft-shelled turtles are limited in a certain growth region, freshwater shrimps can shuttle back and forth in multiple regions, in this way, the freshwater shrimps can elude soft-shelled turtle predation and drive the soft-shelled turtles to move so that the soft-shelled turtles are full of juice, an appropriate amount of shrimp larvae and young soft-shelled turtles are put in the corresponding phases, the respective growth regions are reasonable, the shrimp larvae and the young soft-shelled turtles grow healthily in the corresponding growth regions, the freshwater shrimps can gather residual feeds of the soft-shelled turtles for eating, the water quality is effectively adjusted, two years are used as one cycle, the pond space is effectively used, and economic benefits of soft-shelled turtle and freshwater shrimp culture are increased.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and in particular relates to a breeding method for mixed culture of freshwater shrimp and soft-shelled turtle. Background technique [0002] Freshwater shrimp is also known as river shrimp. The cultivation technology of freshwater shrimp belongs to relatively mature artificial aquaculture technology, especially the pond culture of freshwater shrimp is the most. The freshwater shrimp is tender in quality, delicious in taste, rich in nutrition, and has medicinal value. People favor, freshwater shrimp widely live in lakes, ditches and rivers, and most like to inhabit shallow waters. Aquaculture production is based on pond culture. In order to improve the utilization rate of the pond and the breeding benefits, polyculture will be considered during the culture. There are examples of polyculture of freshwater shrimp and soft-shelled turtle. Because the green shrimp can eat waste such as s...

Problems solved by technology

[0002] Freshwater shrimp is also known as river shrimp. The cultivation technology of freshwater shrimp belongs to relatively mature artificial aquaculture technology, especially the pond culture of freshwater shrimp is the most. The freshwater shrimp is tender in quality, delicious in taste, rich in nutrition, and has medicinal value. It is favored by people. Freshwater shrimps live widely in lakes and ditches. They like to inhabit shallow waters. They are omnivorous animals. The larvae are mainly plankton. Aquaculture production is based on pond culture. In order to improve the utilization rate of the pond and the breeding benefits, polyculture will be considered during the culture. There are existing examples of polyculture of freshwater shrimp and soft-shelled turtle. Because the green shrimp can eat waste such as soft-shelled turtle bait, it can play a role. To regulate water quality and effectively use bait, it can stabilize the water quality of fish ponds. There are usually two existing polyculture methods, one is with soft-shelled turtle as the dominant position, and the other is with freshwater shrimp as the dominant position. , both may cause the growth of the lesser side to be restricted because the water quality is not suitable for the other. At the same time, the existing methods are easy to interfere with each other when fishing due to unregulated and fishing and release time. Faced with the above problems, Further research is needed on the polyculture of freshwater shrimp and soft-shelled turtles
