Brazilian Turtle
In 1981, apple snails were introduced to Guangdong for breeding and consumption. Finally, due to over-breeding and poor taste, they were released into the wilderness to grow in large numbers. It spreads quickly, damaging vegetables and aquatic crops, and the people of Guangdong paid a high price to eliminate it. Likewise, the tiny Brazilian tortoise is also at risk.
1. Disasters of Brazilian turtles
Millions of Brazilian turtles Since it cannot be released into the wild, when a creature is introduced into a new environment, if it gets rid of human control and becomes wild, under the appropriate climate, soil, moisture and propagation conditions, it will be very easy to spread widely and cause large-scale outbreaks. The swarms of single species have harmed local flora and fauna, and even endangered the existence of local endangered flora and fauna, thereby losing biological diversity. These invasive species must have natural enemies to control their population in their original ecological systems, but in new environments there is often no such control system, so these species may spread and cause disasters.
Two and Mainland
In Hong Kong and Taiwan, scientific investigation notes The Brazilian turtle is an "ecological killer" that is consistent in appearance and appearance. Less than 20 years after the Brazilian turtle was introduced to Taiwan, it has settled and established a population in Taiwan, becoming the most common species of turtle in Taiwan. In the wild, the Brazilian turtle will eat large amounts of eggs and tadpoles of small fish, shells and frogs, forming a local ecosystem. Disaster in the water. Taiwan's Keelung River has long been swallowed up by Brazilian tortoises and pipa rats.
Brazilian tortoises can reproduce at the age of 2, while native tortoises do not become sexually mature until they are seven or eight years old. This is one of the reasons why Brazilian tortoises are so cheap. Brazilian turtles have low requirements for food and living environment. They have strong ability to adapt to the environment, grow quickly, have strong fecundity, and are cruel to catch. If they are released casually, fundamentally speaking, because they have no natural enemies, they will enter rivers and lakes in large numbers and rob local turtles of food, which will threaten the existence of local turtles and related species and cause great damage to the original ecological chain.
Two, overseas
The government of Queensland, Australia, recently announced a campaign to exterminate alien black turtles because this turtle species, called the "red-eared turtle", may threaten the development of other parts of Australia. turtles exist.
Red-eared turtles were brought to Australia as pets in the 1960s and 1970s. Since then, they have reproduced in Australia at an alarming rate. When they were proven to be extremely threatening to local ecological stability, their breeding numbers were already quite large.
The International Alliance for the Conservation of Natural Resources has listed this black turtle among the 100 most invasive species. Australian authorities have warned that red-eared turtles could cause serious damage to those cultivating freshwater fisheries because the turtles like to eat freshwater lobsters and other creatures.
In addition, traces of red-eared turtles have also been found in some waters in Victoria and New South Wales.
Queensland also uses a Labrador retriever to hunt red-eared turtles. This hunting dog is very agile and can find urine trails and eggs of red-eared turtles. If turtle eggs are found, trappers will dig them out of the soil and dispose of them. In addition, the Queensland government has also determined that if anyone is found to be raising or selling red-eared turtles, they will be fined 60,000 Australian dollars.
