Episode Details

Tiny Tasmanian swan galaxias, a fish with ancient DNA secrets, teeter on the brink of extinction—threatened by invasive trout and climate chaos. Conservationists celebrate a breakthrough: 180 fish relocated to trout-free zones are thriving and breeding. But experts warn this is just a start; trout, introduced in the 1800s and now a top predator, still loom large. The government faces tough choices balancing fishing economies with survival of native species. Success in protected zones proves targeted action works—but lasting hope demands a bigger, bolder fight against invasive species before these unique fish vanish forever.
