"In the early 20th century, canaries were used as early warning systems in coal
mines to alert miners to rising levels of carbon monoxide.
A small unremarkable fish may fill a similar role in coastal ecosystems around
Aotearoa New Zealand.
Triplefins, or kokopara, are common in a range of shallow coastal habitats
across the country. They are a diverse group of fishes, with 26 endemic species
living on our shores, and they make excellent “canaries” for the coastal marine
environment, helping us to understand and possibly address pollution.
Research using triplefins has already shown increased consumption of
microplastics by fish living closer to urban areas. Studies have also
identified molecular responses to multiple chemical pollutants and described
cognitive damage caused by loss of habitat complexity.
Noise pollution from small boats also has negative effects on coastal fish. And
now, new research is investigating the surprising impact of light pollution on
coastal ecosystems.
We are finding what is called “skyglow” affects triplefin growth patterns, with
consequences for their ability to forage."
