Southern Blue Whiting
Average size about 40 cm, weighing 400 gm. Grey, faintly bluish above, with many small black spots, silver-white below; small, loose scales. Distinguished from small hake by three dorsal and two anal fins, but similar to some other deepwater cads. Deepwater, mainly demersal, but becoming increasingly pelagic in the spring spawning season. Abundant south of New Zealand on the Campbell Plateau and Pukaki Rise in 300-600 m. Caught by trawling. Main catching season during the spawning season, August to early October. A very large resource, probably capable of yielding up to 50,000 tonnes per annum.
