Finding Dory release could trigger further decline of clownfish populations, new study

‘Finding Dory’ has highlighted a serious concern among researchers with regards to the possible further decline of the wild clownfish population as well as the regal blue tangs.

Scientists from the University of Queensland and Flinders University have teamed up in an effort to ensure Nemo can be found exactly where he should be – in his sea anemone home on coral reefs.

The Saving Nemo Conservation Fund aims to provide education, awareness and captive breeding programs to protect popular marine ornamental species that are often captured on reefs for sale in pet shops.

UQ School of Biological Sciences PhD candidate and Saving Nemo Queensland Project Coordinator Carmen da Silva said the marine fish aquarium trade was a major cause of coral reef fish decline.

“What most people don’t realise is that about 90 per cent of marine fish found in aquarium shops come from the wild,” she said.

“Reef fish populations are already struggling due to warmer sea temperatures and ocean acidification caused by global warming.

“The last thing they need is to be plucked off reefs.”

The team has started an ambitious campaign to raise a million fish kisses on social media with the hashtag #fishkiss4nemo.

They hope to capture the attention of Ellen DeGeneres, who voices the loveable yet forgetful Dory in Finding Nemo and the upcoming sequel, Finding Dory.

Saving Nemo co-founders and Flinders University researchers Anita Nedosyko and Associate Professor Karen Burke da Silva said the release of the sequel in June could cause a resurgence of ornamental species being pilfered from reefs — this time Dory’s species, the blue tang.

Miss Nedosyko said people took the wrong message from the film.

“People fell in love with the adorable characters and wanted to keep them as pets, instead of understanding the film’s conservation message of keeping Nemo in the ocean where he belongs,” she said.

Professor Burke da Silva said the team has been running a clownfish breeding program for the past five years, selling sustainable clownfish to local aquariums.

“Clownfish are extremely easy to breed and females lay many eggs at a time so there is really no reason to collect them from the wild. Nursery-bred fish are also far happier and healthier in tanks than wild-caught fish,” she said.

The researchers are also examining how anemone venom can be used as a bio-active anti-cancer product.
