The two orange fish are pet goldfish. “Releasing exotic fish into waterways harms natural ecosystems by forcing native species to compete for habitat,” Bloxham said. “This causes muscles to contract involuntarily bringing them to the surface, where they can be scooped up with long-handled nets.”The exotic fish were then euthanised and sent to a plant where they turned into bio-ethanol, which can be burnt. Bloxham said it is important to dispose of unwanted pets responsibly for the good of the environment and of the fish.
