Pond special for high-density breeding of crawfishes

Abstract

The invention relates to the field of ponds special for crawfishes, in particular to a pond special for high-density breeding of the crawfishes. The pond includes a planting area arranged at the center, pond rock banks arranged around the periphery of the planting area and crawfish breeding areas arranged between the planting area and the pond rock banks; a water inlet and a water outlet are formed in the two sides of each crawfish breeding area, multiple brackets for the crawfishes to climb to hiding places are arranged at the upper end of each crawfish breeding area, multiple glass bricks which are connected with one another and used for preventing the crawfishes from escaping are arranged on the pond rock banks, and the planting area, the crawfish breeding areas and the pond rock banksall of which are nested with one another are utilized to achieve maximum utilization of the smallest area; when the pond is not used for breeding the crawfishes, crops can be planted; when the pond isused for breeding the crawfishes, aquatic plants are planted, feces of the crawfishes is utilized as the fertilizer for the crops in the next season, and ecological planting and breeding are achieved. By utilizing bamboo floating plates and the glass bricks, the hiding spaces for the crawfishes are increased, the crawfishes are prevented from escaping, and the pertinence is high.

Description

technical field [0001] The invention relates to the field of special ponds for crayfish, in particular to a special pond for high-density crayfish breeding. Background technique [0002] Crayfish are benthic reptiles. Monoculture in ponds makes most of the water in the ponds not fully utilized, which affects economic benefits. Some farmers adopt polyculture of fish and shrimp or multi-species polyculture and crop rotation to improve the utilization rate of ponds. Improve economic benefits, especially in filter-feeding and herbivorous ponds, because there is almost no contradiction between the feeding habits and living habits of lobsters and main fish, there is no need to reduce the amount of stocking because of mixed crayfish, but fish and crayfish Different growth and maturity periods and aquatic plants are different, which will cause a single variety of species in the pond for a long time, which is not conducive to the ecological cycle. It is necessary to increase the fert...

[0002] Crayfish are benthic reptiles. Monoculture in ponds makes most of the water in the ponds not fully utilized, which affects economic benefits. Some farmers adopt polyculture of fish and shrimp or multi-species polyculture and crop rotation to improve the utilization rate of ponds. Improve economic benefits, especially in filter-feeding and herbivorous ponds, because there is almost no contradiction between the feeding habits and living habits of lobsters and main fish, there is no need to reduce the amount of stocking because of mixed crayfish, but fish and crayfish Different growth and maturity stages and aquatic plants are different, which will cause a single variety of species in the pond for a long time, which is not conducive to the ecological cycle. It is necessary to increase the fertility of the culture soil in the pond to achieve the ecological cycle.
