Distribution – Eastern rock blackfish are found in surge areas of rocky shorelines along the NSW coast, as well as southern Queensland, Victoria and north-eastern Tasmania.
Size – Maximum weight of approximately 9kg and a length of 76cm.
Characteristics – Rock blackfish have a blackish-brown to grey body. They possess a dorsal fin (with 13 spines) that extends to the tail base. Their diet includes cunjevoi, red bait crab and cabbage seaweed. They are a tough fighter and a great sportfish, using their strong swimming tail to hide under rock ledges or in crevices.
Confusing species – Silver Drummer (Kyphosus sydneyanus) are found on coastal reefs in NSW, South Australia and southern Western Australia. They are distinguished from the eastern rock blackfish by their silver colour and dorsal spine count of 11 instead of 13.
Confusing species – could be confused with Triggerfish, however these fish have a dorsal fin rather than a single, serrated dorsal spine.
