S4.E5 From pets to pests - ornamental fish gone rogue

S4.E5 From pets to pests - ornamental fish gone rogue

Author: James Donaldson, Wet Tropics Waterways October 4, 2022 Duration: 10:25

They might look pretty – or at least, pretty harmless, but Australia's ornamental fish trade can pose a serious threat to our waterways. Once an invasive is established, it makes eradication almost impossible, which means prevention is always better than cure.

In this episode we're joined by freshwater fish biologist Mariah Millington to find out exactly what impact ornamental fish are having on our native species, as well as what we can do to encourage responsible fish ownership.


There's a vital, living connection between the lush, rainforested rivers of Far North Queensland and the vast blue expanse of the Great Barrier Reef. What happens in one profoundly affects the other. Hosted by James Donaldson from Wet Tropics Waterways, the Reef And Rivers Podcast explores this intricate relationship by giving a voice to the people who know it best. Each conversation moves beyond abstract science to ground-level stories, offering a direct line to farmers, Traditional Owners, researchers, and community volunteers who are actively engaged with the landscape. You'll hear about the specific critters-from tiny insects to majestic fish-that indicate a waterway's health, and learn about the practical, often ingenious projects aimed at protecting them. This isn't just a series of interviews; it's an ongoing audio documentary about the interdependence of an entire region's lifestyle, economy, and environment. By tuning into this podcast, you gain an understanding of how everyday actions on land ripple out to the reef, and more importantly, how collective effort is working to ensure both these iconic systems thrive for generations to come. The discussions are grounded, hopeful, and filled with the kind of specific details that only come from firsthand experience.
