Abstract

The invention relates to a Chinese softshell turtle breeding method. The method comprises a parent breeding process. The parent breeding process comprises the following steps: before the parents are put into a breeding pond, adding quick lime into the breeding pond to carry out water pond cleaning, pumping the water in the breeding pond and sun drying the pond; refilling the pond with water, sterilizing the parents with povidone iodine solution and then putting the parents into the breeding pond; performing bait feeding and water quality control by stages, wherein the bait comprises a turtle feed, fresh fishes and / or shrimps and vegetable; the water quality control enables the transparency of water in the breeding pond to be 25-40 cm by water change operation. The method is more scientific and is easy to produce and operate, in general the parent breeding process greatly improves the egg yield of parents and the hatching rate of turtle eggs, and moreover the vitality and the survival rate of the hatched juvenile soft-shelled turtles are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of soft-shelled turtle breeding, in particular to a breeding method for soft-shelled soft-shelled turtles. Background technique [0002] Soft-shelled soft-shelled turtle is a famous and special aquaculture species, which is rich in nutrition and its market demand is increasing day by day. Anhui Province is located in the two major water systems of the Yangtze River and the Huaihe River. It is also the main production area of ​​soft-shelled turtles. The annual output of Chinese soft-shelled turtles in Anhui reaches more than 20,000 tons. In the soft-shelled soft-shelled turtle populations along the Yangtze River in Anhui, soft-shelled soft-shelled soft-shelled turtles with black abdomens are often found. Local people are used to calling them "black soft-shelled turtles". They are widely distributed in Wuhu and Chaohu cities, and a small amount is also distributed in Tongling City. In the local area, soft-she...
