journal contribution

There was a significant difference in the presence of melanised muscle in sand flathead from two sites within the Tamar Estuary (northern Tasmania), with higher proportion of sand flathead from Deceitful Cove with this condition. Presence of melanisation was not related to length or weight of the fish. No parasitic infections were detected in the muscles of the affected sand flathead. However, concentration of zinc in melanised regions of muscle in the affected fish was significantly higher, about 1.7 to 1.8 times, than non-melanised regions of muscle in the same fish. Furthermore, the concentration of zinc in melanised regions of affected fish was on average about 2.0 times higher when compared to muscle of unaffected fish that had no melanised spots.
