Breeding method for soft-shelled turtles

Abstract

The invention discloses a breeding method for soft-shelled turtles. The method includes the steps of selection and construction of parent soft-shelled turtle breeding pool, selection of parent soft-shelled turtles, daily management, selection of hatching boxes, and spawning and hatching. Strict management is adopted in the breeding method, each link in the reproductive process of the soft-shelled turtles is controlled scientifically, the spawning rate and the hatching rate in the reproductive process of the soft-shelled turtles are improved, and the survival rate of young soft-shelled turtles is high.

Description

technical field [0001] The invention relates to the field of reproduction, in particular to a method for breeding soft-shelled turtles. Background technique [0002] The soft-shelled turtle is a temperature-changing animal, amphibious on land and water, and breathes with its lungs; it likes to live in rivers, lakes, and ponds, often floats to the surface of the water, stretches out the tip of its snout to breathe, and often sunbathes on land; soft-shelled turtles are very sensitive to changes in external temperature, The law of life is closely related to the change of external temperature. At 10-12°C, the soft-shelled turtle enters hibernation, and when the water temperature rises to about 15°C in spring, it gradually wakes up from hibernation and begins to feed; when the temperature is above 20°C, the male and female soft-shelled turtles mate and lay eggs. 25-30°C is the optimum temperature range for soft-shelled turtles to ingest and grow, and it is also the best season fo...

[0002] The soft-shelled turtle is a temperature-changing animal, amphibious on land and water, and breathes with its lungs; it likes to live in rivers, lakes, and ponds, often floats to the surface of the water, stretches out the tip of its snout to breathe, and often sunbathes on land; soft-shelled turtles are very sensitive to changes in external temperature, The law of life is closely related to the change of external temperature. At 10-12°C, the soft-shelled turtle enters hibernation, and when the water temperature rises to about 15°C in spring, it gradually wakes up from hibernation and begins to feed; when the temperature is above 20°C, the male and female soft-shelled turtles mate and lay eggs. 25-30°C is the optimum temperature range for soft-shelled turtles to ingest and grow, and it is also the best season for artificial breeding. When the temperature exceeds 33°C, they will search for holes to avoid the heat; soft-shelled turtles have high economic value, but artificial breeding tends to cause spawning rate , low hatchability and juvenile survival
