Study reveals mulloway are cross-border breeders

ACCORDING to a mulloway study conducted by the Victorian Environment Department, the prized sportfish species travels hundreds of kilometres from Victoria to breed in South Australia.

The study has revealed mulloway travel a whopping 450km through rivers and a stretch of ocean from Victoria’s Glenelg River to SA.

The study confirmed the species swims from Victoria consistently to breed at the mouth of the Murray River and Coorong region.

According to a report in the Adelaide Advertiser, fish ecology scientist Jason Lieschke said it was unusual for small fish, such as mulloway, to travel so far.

“(In other states) they usually only travel 50km from each other (to breed) … but this is 450km away from each other,” he said.

“For these fish … it seems a long way to swim.”

The study showed some of the fish stayed in South Australian waters after breeding while others swam back to Victoria.
