After years of declining mulloway catches in Perth, the species is set to be restocked along the west coast.
Fisheries Minister Norman Moore announced yesterday that a $280,000 project would breed 30,000 fingerlings in Fremantle and then release them to boost numbers of the fish.
Mulloway can be caught in the Swan River and metropolitan beaches and is prized by recreational fishers. Recfishwest chief executive Andrew Rowland said there was overwhelming anecdotal evidence that mulloway were not returning to the river in the numbers they once did.
The released fish will be marked with a dyed otolith, a small bone within a fish's inner ear. The project comes after the announcement last year that prawns would be restocked in the Swan and Canning rivers.
