  • Size Range
    Much of the Australian popular literature gives a maximum size of 60 cm and weight 10.4 kg. This appears to be anecdotal with no official figures indicating that the species grows this large. Redfin commonly grow to 40 cm to 45 cm in length and weights of 1 kg to 2 kg.

Introduction

The Redfin was introduced to Australia from Europe around 1860. Since that time it has become widespread throughout much of New South Wales and Victoria.

Identification

The Redfin can be recognised by its pattern of six or more tapering bands on the sides of the body, a distinct black blotch at the rear of the first dorsal fin, and red pelvic, anal and caudal fins. It has a humped back behind the head, a large mouth, a slightly forked caudal fin, and two dorsal fins, the first with 13-17 strong spines.
