A new community resource for mapping feral fish

FeralFishScan is a new community website for collecting evidence of feral fish. Feral fish (also called 'pest fish') cause enormous damage to our rivers and native fish populations. If you have seen or caught feral fish in your local area, record the details here to help identify feral fish hot-spots across our catchment.
