FOLLOWING on from the stocking late last year of 1,200 juvenile dusky flathead into Lake Macquarie, NSW fisheries scientists recently released 40 larger flatties fitted with acoustic tags.

Reared by DPI’s Port Stephens Fisheries Institute, the fish measured about 20cm and were released around the artificial reef near Galgabba Point in the southern area of the lake.

Signals from the tags fitted to the 40 little duskies will be picked up by an array of listening stations, which will allow the scientists to track detailed movements of the fish in the vicinity of Galgabba Point, as well as more general movements around the lake.

This data will provide important information on the movements and habitat use of stocked dusky flathead and will help guide future stocking events along the coast.

Aside from dusky flathead, NSW DPI says its continuing work to breed and stock other key species such as kingfish and mulloway.
