A breeding method for improving the spawning quantity and spawning quality of Hanshou soft-shelled turtle

Abstract

The invention discloses an aquaculture method for improving Hanshou soft-shelled turtle egg laying amount and quality. The method includes the steps of carrying out daily management of an aquaculture pool, determining the proportion of female soft-shelled turtles and male soft-shelled turtles put into the aquaculture pool, preparing aquaculture feed and supplying the feed. The method has the advantages that operation is easy, raw materials are easy to get, production cost can be reduced, and the soft-shelled turtle egg laying amount and hatching survival rate can be improved; because incandescent lamps are additionally arranged in the aquaculture pool, more light can be scattered to the soft-shelled turtles, VD synthesis is promoted, lucipetal worms can be trapped, and more fresh protein bias can be provided for soft-shelled turtle aquaculture; because quick lime is applied, harmful organisms in water can be killed, the PH value of the water can be adjusted, and more calcareous substances can be supplied; the male soft-shelled turtle and female soft-shelled turtle aquaculture proportion is increased to (5-6):1, male soft-shelled turtles can be less injured, the soft-shelled turtle egg productivity is increased, and the egg laying amount is improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a breeding method for improving the spawning quantity and quality of the Hanshou soft-shelled turtle. Background technique [0002] "Han Shou soft-shelled turtle" belongs to the authentic Chinese soft-shelled turtle, which is an indigenous cultured species with distinctive regional characteristics. Compared with other soft-shelled turtle species, the adult soft-shelled turtle has the characteristics of large thin slices, wide and thick skirt, white and red abdomen and consistent color. "Han Shou Turtle" has pure, tender and delicious meat, and its nutritional value and medicinal value are superior to other species. The spawning and incubation period breeding of the "Han Shou soft-shelled turtle" female soft-shelled turtle is an important link in the whole breeding process. Under normal temperature, every 500g female soft-shelled turtle can lay about 20 eggs a year, and about ...

Problems solved by technology

The spawning and incubation period breeding of the "Han Shou soft-shelled turtle" female soft-shelled turtle is an important link in the whole breeding process. Under normal temperature, every 500g female soft-shelled turtle can lay about 20 eggs a year, and about 15 hatchlings can be hatched; but in Every year when spawning begins in May, the Dongting Lake area is usually low temperature and rainy, and the soft-shelled turtles are in the late wintering stage due to their lack of nutrition. The eggs laid by female soft-shelled turtles are generally underdeveloped, and the embryos are often incomplete or easily die in the hatching process. The normal emergence rate is as low as 45%, which seriously restricts the production of turtle seedlings and greatly reduces the economic income of farmers.
