The first artificially bred baby loggerhead turtles in China
was born in Qingdao Haichang Polar Ocean Park
According to Qingdao Haichang Polar Ocean Park, 7 small loggerhead turtles (national first-class protected animals) are in the park’s conservationists Carefully care for the loggerhead turtle to emerge from the shell. This is also the first successful artificial breeding of loggerhead turtles in China. It also marks another major achievement in the field of marine animal breeding in Qingdao Haichang Polar Park.

It is understood that on June 1 this year, a female loggerhead turtle living in Qingdao Haichang Polar Ocean Park lay 30 eggs, after more than 70 days of incubation Beginning on August 11, animal breeding experts found signs of loggerhead turtles breaking their shells, and judged that loggerhead turtles might break their shells within 24 hours, and then conducted 24-hour observations day and night, after more than 20 After hours of waiting, at 11:00 on August 12, the first little loggerhead turtle bravely broke its shell. Currently, the first little loggerhead turtle is about 8 cm long and weighs 25 grams. Childcare worker Mu Liangchen told reporters: "When the baby loggerhead turtle is just hatched, the egg yolk in the body is not completely absorbed, so it will not take food immediately. Generally, it takes 48 hours to start eating slowly. We choose jellyfish_ Span20span, krill and other easily digestible foods are used for baby loggerhead turtles."

After nearly a week of long waiting, there are already 7 babies. Loggerhead baby turtles (currently unable to distinguish males from females) have bravely broken their shells. After about a week of observation, the current 6 baby loggerhead turtles are developing normally, all weighing about 25g, with an average length of 8.5cm, and all have been eating steadily; 1 baby loggerhead turtle is born with developmental abnormalities and weak physique.At present, the eating ability is relatively poor, and the nurses are taking care every day; the loggerhead turtle mothers also specially arrange a separate breeding pond for postpartum rehabilitation. It is reported that in 2020, the China Sea Turtle Conservation Alliance awarded Haichang Ocean Park the title of "National Sea Turtle Conservation and Breeding Base". As a sub-project of Haichang Ocean Park, this is the first successful Qingdao Haichang Polar Ocean Park. The breeding of loggerhead turtles is also the first aquarium to successfully breed loggerhead turtles in China. According to Wang Bin, deputy director of the Conservation Department of Qingdao Haichang Polar Ocean Park, there are two major difficulties in the breeding of loggerhead turtles: one is the long incubation cycle of loggerhead turtle eggs. During the incubation period of more than 70 days, turtle eggs are easily contaminated by molds, insect eggs, etc., and become moldy and deteriorate. The nurses need to continue to follow the incubation of tortoise eggs and remove unfertilized eggs or moldy eggs in time. To prevent pollution to the hatching environment; second, during the hatching period, the development of tortoise eggs requires relatively high temperature and humidity. A stable and suitable temperature and humidity must be maintained at all times before the tortoise eggs can develop normally. Once the temperature and humidity are not up to standard or fluctuate too much Large, it is easy to cause the tortoise egg to stop developing.
According to Zhou Qingjie, assistant general manager of Qingdao Haichang Polar Ocean Park: As a national science education base, Qingdao Haichang Polar Ocean Park has been committed to the protection, reproduction and research of polar marine animals. The first artificially bred grey seal in China; successfully hatched China’s first rock-hopping penguin; the first purebred Arctic wolf triplets naturally bred under artificial breeding conditions in the province; the world’s first artificially bred pseudonym was successfully born At the same time, the killer whale has successfully bred a variety of rare marine species such as fur seal and whitetip shark. In the past 15 years, Qingdao Haichang Polar Ocean Park has filled a number of gaps in the field of polar marine animal research in my country, and its research on polar animals has reached the international leading level, providing valuable data for the artificial breeding and breeding of rare marine animals in the polar regions in the future. material. At the same time, it provides reference data for the rational development of polar resources and protection of polar ecology in the future.
