Study: Light pollution threatens the proliferation of a famous fish World of miscellaneous -

An artificial light that reaches coral reefs may have a strong impact on the breeding of bright orange clowns, which are best known in the film "Finding Nemo" or "Finding Nemo."

The study, conducted by Australian researchers and published in the journal Nature Leagues on Wednesday (July 10, 2019), shows that an increasing amount of industrial light at night in coral reefs, even at relatively low levels, obscures the natural signals that stimulate eggs This fish on hatching after dusk.

The researchers found that exposure to light at night had a tragic effect on hatching, where the eggs of clown fish, incubated under artificial light at night, were not simply hatched.

Scientists said that light pollution or industrial light at night, which can have harmful effects on many living organisms and ecosystems, is increasing by about 2% per year worldwide.

"The predominant result is that pollution from industrial light can have a devastating impact on the success of coral reefs," said Emily Faubert of the University of Flinders in Adelaide, Australia. "The presence of light clearly interferes with the environmental signal that triggers clowning," she said.

These results are also likely to apply to other reef fish, he said, because many share similar breeding behaviors, including the timing of hatching.
