Description
Technical Field
The invention belongs to the technical field of wild animal protection, and particularly relates to a method for building and regulating an overwintering environment for artificial breeding of green sea turtles.
Background
The green sea turtle is a first-grade protective wild animal in China and is in an extremely endangered state at present. The green sea turtles have strict requirements on the temperature and the illumination for overwintering and breeding, and under natural conditions, the green sea turtles generally migrate for a long distance to find the proper temperature and illumination. In recent years, egg producing areas and habitats are damaged due to fishery fishing, marine pollution and the like, so that the green sea turtle population in China is seriously damaged. Therefore, the government of China takes a plurality of measures to protect the turtles, such as setting up natural protection areas for the turtles to protect important habitats of the turtles. The national natural preservation district management method of the guangdong huidong sea turtle is specially issued by the people government of Guangdong province in 2013, and the protection strength of the sea turtle is enhanced.
Nevertheless, the recovery speed of the population of the sea turtles in China is still very slow due to the restriction of a plurality of factors such as ocean unordered development and the like. The breeding of the green sea turtles under the artificial condition is undoubtedly an important measure for recovering the wild sea turtles in China.
Therefore, a nature-simulated green sea turtle breeding method suitable for the eastern area of China is designed by simulating the overwintering and breeding environment of the green sea turtle in the field, particularly simulating the water temperature and illumination of the overwintering and breeding of the green sea turtle, and the full artificial breeding of the green sea turtle is realized.
Disclosure of Invention
Aiming at the problems, the invention provides a method for building and regulating the overwintering environment for artificial breeding of the green sea turtles.
The technical scheme of the invention is as follows: a method for building and regulating an overwintering environment for artificial breeding of green sea turtles mainly comprises the following steps:
s1: the green sea turtle breeding ground is set up
Establishing an indoor overwintering pond and an outdoor breeding pond suitable for green sea turtles to live in coastal areas, connecting the indoor overwintering pond and the outdoor breeding pond through a migration corridor, introducing seawater into the indoor overwintering pond and the outdoor breeding pond, and arranging an artificial beach outside the outdoor breeding pond;
