The redfish is easily recognised by its entirely red body, a large mouth with an underhung jaw and large eyes. It also has spikes on the front gill cover and the front of the dorsal and anal fins. The spikes are non-toxic.
Like other deep-sea fish, it grows slowly and can be over 60-years-old and up to 100 cm long. It is an excellent eating fish that can be caught on longline or hook. When you lift it out of the deep water, the fish dies immediately and the eyes “pop-out” due to the pressure difference.
The redfish is common in fjords and waters to the north to Uummannaq and Tasiilaq. It lives at depths between 50 and 1000 metres, and feeds on crayfish, small fish and fish fry.
Its primary spawning ground is in the Irminger Sea southwest of Iceland. The female gives birth to live fry during the month of April-May, and the fry are transported by sea current to growing areas in south-eastern and southern Greenland.
The related species, deep-sea redfish, resembles the golden redfish and has the same distribution, but is known for a distinct projection on the lower jaw. The rarer species, Norway redfish, are recognised by 3-4 dark crossbands and are only found off Southeast Greenland.
