Embodiment 1

[0017] A. Create pond conditions: choose a flat bottom with a quiet environment, leeward and sunny environment, convenient water intake and drainage, good water quality, an area of ​​5-10 mu, a water depth of 1.2-1.8 meters, a pond ridge 40-50 cm above the water surface, and a silt layer of 10-20 cm. pond. Cement slope protection is adopted around the pond, and escape protection facilities are set on the top of the slope. The corners and joints of cement slope protection should be smooth and seamless. Asbestos tiles are used in the middle of the pond, inclined at an angle of 15 degrees to the horizontal plane, 1.5 meters wide, and about 2 / 3 of the length of the pond, and a sun-drying platform integrating the functions of a feed platform and a balcony is set up. Two water pumps are symmetrically installed on the side of each pond for the convection circulation of the water body in the pond to increase oxygen when the temperature is high and low oxygen.

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, ...
