Poster: Fish Ageing

This poster shows how fisheries scientists at the Department of Primary Industries and Regional Development (DPIRD) use scales and, more accurately, otoliths, to age fish. Determining the ages of fish tells scientists the health of the overall population. From this information, informed fisheries management practices can be applied to ensure fish for the future.

Fact Sheet: Fish ageing

The Department of Primary Industries and Regional Development (DPIRD) has the largest collection of fish ages in Australia. Our fisheries scientists have processed and aged 381,000 fish (December 2022), ranging from small estuarine to large marine species. This information is held in a database at the Western Australian Fisheries and Marine Research Laboratories, which dates back to 1990 (and even earlier for some species!).
