Artificial breeding method for soft-shelled turtles

Abstract

The invention discloses an artificial breeding method for soft-shelled turtles.The artificial breeding method specifically comprises the steps of pond building, intensifying, spawning inducing, incubating, larva feeding and processing.According to the artificial breeding method for the soft-shelled turtles, indoor breeding is adopted, breeding conditions are precisely controlled, soft-shelled turtle hibernation is avoided, the ripening time is shortened, and the economic income is increased; parent soft-shelled turtles are intensively bred, and the egg laying amount is increased; spawning inducing and artificial insemination are conducted, the spawning period is obviously advanced, and the number of germ cells is increased to centralize spawning so that convenience can be brought to managing and breeding; the number of female soft-shelled turtles is increased, seminal fluid is fully utilized, and the fertility rate is increased; eggs are collected in time after spawning and are centrally managed, the incubation environment is precisely controlled, sand on the lower layer of an incubation pond is thick, sand on the upper layer of the incubation pond is thin, water retention and breathability are achieved, two layers of germ cells are laid vertically, the situation that the extremely heavy sand layer damages the germ cells is avoided, and the hatchability and the survival rate are increased; young soft-shelled turtles out of shells are put into a culture pond in time, two times of disinfection is conducted on the culture pond, microorganisms are added, the safe, efficient and non-toxic purposes are achieved, and the survival rate is obviously increased.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for artificial breeding of soft-shelled turtles. Background technique [0002] Soft-shelled turtle, also known as soft-shelled turtle, water fish, tuanyu, and tortoise, is an oviparous amphibian reptile. Its head is like a turtle, but its carapace does not have turtle-like stripes. The edge is soft and skirt-like, and its color is dark green. The soft-shelled turtle often lives in the mud and sand at the bottom of the water, and likes to eat small animals such as fish and shrimp, as well as melon peels, grasses and grains. Soft-shelled turtle meat has the delicacy of five kinds of meat: chicken, deer, beef, sheep, and pig, so it is known as "gourmet meat with five flavors". It is not only delicious, high in protein and low in fat, but also a nourishing treasure containing a variety of vitamins and trace elements, which can enhance the body's disease resistance and r...

Problems solved by technology

[0003] Currently on the market for soft-shelled turtle breeding methods, broodstock can mature at an average age of about 4 to 5 years, which takes a long time, and the cost of breeding farmers is high, and the breeding pressure is high. Moreover, the fertilization and maturation rate of soft-shelled turtles are not ideal, and the investment is large and the income is low. Method for Artificial Breeding of Soft-shelled Turtle
