This summer, there was another pixar cartoon movie”Finding Dory”. There are a lot of cute animals in the movie. But the movie itself actually have negative impact to the nature. you may ask why?
Here are some stories,nemo fish is actually belong to the clownfish family. And every year, over 1 million of them was taken from the ocean. After the last ocean movie”finding nemo” in 2003, what people didn’t expect is an 40% increase of the nemo fish in the pet fish market and aquarium trade. And, this is not the end of the bad news, they are really vulnerable to extinction for several reasons: First, the clownfish are dependent on stinging sea anemones, which thrive on only healthy coral reefs, to hide from the predators. But, due to rising temperature, the coral dies. And this makes the clownfish have less place to live. Second, the carbon dioxide make the see water more acidic, and this will block the signal that lead the clownfish back to home. And the commercial aquarium trade makes their situation even worse, as 90% of the commercial aquarium fish comes from the ocean.
Therefore, there are some scientists actually start a program called “ Saving Nemo Conservation Fund“. They are trying an alternative to collecting wild clownfish from the ocean. Nursery breeding is an easy way to prevent overcollection of clownfish in the wild. And for the 7 out of 28 species of clownfish are bred in Australia . Unfortunately, none of the ten host anemone species are bred in captivity for aquariums.
So, how about Dory? Well, it turns out dory is not as lucky as nemo, as they are currently unable to be bred in captivity. So,if you see a Royal Blue Tang, as known as Dory, in an aquarium shop it will have to come from the wild.
