Technical Field

The invention belongs to the field of turtle breeding, and particularly relates to a turtle breeding method capable of improving survival rate.

Background

The turtle is a temperature-variable animal, is amphibious and breathes by the lung, so a land beach with enough area is required around or in the center of the turtle pond for the turtle to move on land. The soft-shelled turtles have sensitive sound response to the surrounding environment, and can quickly submerge into underwater silt as long as the surroundings are slightly static, so the feeding environment must be kept quiet. The turtle is very unfavorable for growth and reproduction if the turtle is often frightened.

The soft-shelled turtle likes to stay in an environment with good water quality, so water is changed frequently, and water is changed once in 2-3 days.

The soft-shelled turtles are mostly sunned, because the ultraviolet rays in the sunlight are utilized to kill pathogenic bacteria on the body surface, promote the healing of the injured body surface, and improve the body temperature by sunning the backs to promote the digestion of food;

the traditional breeding method is easy to cause low survival rate of the soft-shelled turtles, and in order to improve the survival rate of the soft-shelled turtles, the soft-shelled turtle breeding method capable of improving the survival rate is provided.
