Silver Drummer

The silver drummer has an oval to circular when viewed from the side which is not compressed; the dorsal profile of the head is sloping between the area between the eyes and the snout with a characteristic bulging head profile. It has a continual dorsal fin which as a spiny anterior part and a soft-rayed posterior part, the spiny part being normally more than half as long again as the soft-rayed part. There are 10-11 spines and 11-12 soft rays in the dorsal fin while the anal fin has 2-3 spines and 10-12 soft rays. There is a total of 52-66 scales in the lateral line of which 42-56 are pored. It has a short caudal peduncle, a slightly emarginate caudal fin which has slightly rounded lobes. This is a large species which attains a maximum total length of 80 centimetres (31 in) and a maximum weight of 1.1 kilograms (2.4 lb).

The silver drummer is found in the south-eastern Indian Ocean and the south western Pacific Ocean off Australia and New Zealand. In Australia its range is in the southern part of the continent where it occurs from Shark Bay in Western Australia, south to the southern coast of the continent, east to Tasmania and north to Fraser Island in Queensland. It is also found in the Tasman Sea around Lord Howe Island and Norfolk Island. In New Zealand it has been found as far south as Jackson Bay on the west coast of South Island but it is only really common around the North Island. Records from the islands in the Tasman Sea are probably misidentifications for Kyphosus bigibbus.

The silver drummer is regarded as a fish which puts up a good fight when caught by the angler and is therefore popular. However, most people consider its flesh to be inedible.
