The sequel sees forgetful blue tang fish Dory take the lead role as she regains some of her memory ands heads off on a watery quest of self-discovery.
But according to experts, following the release of Finding Nemo sales of pet clown fish, like Nemo, skyrocketed and meant a huge number of clown fish were bred in captivity to meet the demand.
Now, marine biologists are concerned people will want blue tang fish like Dory which, unlike clown fish, do not breed well in aquariums.
“As Dory graduates from sidekick to leading lady, the lack of captive-bred options will drive collectors to source more blue tangs from the wild — a harvest that’s often unregulated and destructive,” one source.
Already, researchers are trying to find a viable way to breed blue tang “Dory” fish in captivity ahead of the movie’s release.
But Ellen DeGeneres, who voices Dory, has thankfully spoken out about the practice of keeping exotic fish in tanks, saying: “I think that fish should be in the ocean. It’s what this whole sequel is about.”
“We have to protect our oceans [and] hopefully that discussion starts with this film, because we really need to protect that environment.”
