Fact Sheet: Fish 'n' Chips

Beneath the waters of the Murray–Darling Basin's rivers and wetlands, our native fish live hidden lives. Most of us only see them when they are on the end of a fishing rod, but what exactly do they get up to under the surface of the water?

To discover their secrets we need to tag them to investigate where, when and why they move. Compiling information from lots of individuals is important for us to understand the biology and needs of different fish species. This type of information is essential so that we can manage rivers to ensure our native fish populations and communities are self-sustaining and healthy.
