Lower Lakes, Coorong fish population rebounding: DEWNR

Fish populations are booming in the Coorong and Lower Lakes, according to the Department of Environment, Water and Natural Resources (DEWNR).

A recent survey found more native fish than in any year since 2010-11 using the fishways which allow them to travel through the barrages at the lakes’ southern end.

Twenty-seven species were identified among 1.78 million fish.

Three quarters of them were whitebait, or sandy sprat.

But juvenile congolli and galaxias were among the other species found, which encouraged researchers because it showed they were migrating between salt and fresh water areas at different points in their life cycles, as nature intended.

DEWNR spokeswoman Adrienne Rumbelow said the findings indicated the estuary's productivity.
