Exploring the secret lives of Victoria’s premier fisheries species

Why track fish?
Determining where, when and why fish move is critical in understanding the distribution and availability of fish for fishing, and forms a basis for the sustainable management of fisheries.

How do we track the movements of fish?
Until recently, the movements of fish have been investigated using conventional tags and catch/release fishing.

Which species of fish are being tracked in Victoria?
Scientists from the former Department of Sustainability and Environment have tracked the movements of black bream and dusky flathead in the Gippsland Lakes, and black bream in the Yarra/Maribyrnong estuaries.
