Mimic-ecological cultivating method for fishes, turtles and shrimps

Abstract

The invention discloses a mimic-ecological cultivating method for fishes, turtles and shrimps. The method comprises the following four links of creating pond conditions, reasonably stocking fries, automatically regulating water quality, and carrying out scientific cultivation and management. In the invention, a traditional consciousness that turtles are the natural enemies of shrimps, therefore, the turtles and the shrimps can not be cultivated in a mixed mode is broken up, and through cleverly using the biological links and regulating functions of cultivated breeds in the process of artificial cultivation, both the utilization rate of feeds is raised, and the diseases are reduced, thereby promoting the qualities and specifications of commercial fishes, turtles and shrimps. Meanwhile, in the invention, a characteristic that fishes, turtles and shrimps are living in different water layers is fully used, therefore, the utilization ratio of a water body in a pond is effectively improved, so that by using the technical scheme of the invention, the average annual output per mu of commercial turtles is more than 350kg, the average annual output per mu of large-size commercial freshwater shrimps is more than 40kg, and the average annual output per mu of large and medium-sized grass carps and spotted silver carps is more than 150kg. The method disclosed by the invention is universally applicable to the artificial large-scale cultivation of high-quality freshwater fishes, turtles and shrimps in the middle and lower reaches of Yangtze River.

Description

technical field [0001] The invention relates to a pond polyculture technique for fish, turtle and shrimp, which belongs to the technical field of freshwater cultivation, in particular to a method for imitating ecological cultivation of fish, turtle and shrimp. Background technique [0002] Soft-shelled turtles and shrimps are delicious and nutritious, and are valuable aquatic products welcomed by consumers. In the middle of the 1990s, the artificial aquaculture industry of special aquatic products such as shrimp and soft-shelled turtles developed rapidly. Specialized pond farming, represented by shrimp farming in shallow ponds, paddy fields, greenhouse soft-shelled turtles, and high-density soft-shelled turtles in ponds, greatly improved the productivity of shrimp and soft-shelled turtles. The production of aquaculture alleviates the contradiction between supply and demand in the market, but due to the high density of aquaculture in special ponds, high incidence of disease, ...

AI Technical Summary

Problems solved by technology

The current technology of polyculture of fish and turtle and polyculture of fish and shrimp has improved the quality of commercial shrimp and soft-shelled turtle compared with special pond culture, but the water quality management and disease control of the culture pond are still the main problems for many farmers. The main defects of the prior art are still many diseases in ponds, many medications, and unstable output.
