about new zealand bluenose

Bluenose belong to the Centrolophidae family (raftfish, medusafish). They are a dark metallic blue-black to grey on the back of the body, shading to silver on the sides and belly. Bluenose is distinguished from Groper by a blunt snout and laterally compressed body with large eyes set low in the head. Bluenose have larger mouths and more prominent dorsal fins than (closely related) Warehou. They are found in the temperate waters of the Southern Hemisphere. They like rough ground on the outer shelf and upper slope, especially from 100 to 500 meters.

They grow quickly for the first two years, the females faster than the males, with adults first spawning at four to five years.


Bluenose have been landed from New Zealand waters since the 1930s, although the bluenose target line fishery only developed in the late 1970s. Bluenose was introduced to the Quota Management System in 1986; the first fully quantitative stock assessment modelling was carried out in 2011 and assumed a single New Zealand wide biological stock. The assessment indicated that the stock abundance dropped below the management target level in the early 2000s, and a series of catch reductions was implemented to rebuild the stock.
