612:(DFO) considers this species endangered based on a 2012 Committee on the Status of Endangered Wildlife in Canada assessment. The status report identified that catches of cusk in the DFO summer bottom-trawl survey had declined by roughly 90% from 1970 to the late 1990s. A landings limit of 1000 mt was put in place in 1999 in the 4X North American Fisheries Organization area and was further restricted to 750 t and expanded to include the 4VWX5Z NAFO areas in 2003. Cusk are still commonly caught as bycatch in the longline and lobster fisheries and can be found in supermarkets in Atlantic Canada despite its threatened status. A study that was conducted in the Gulf of Maine region showed that the conservation status of cusk was partly dependent on future greenhouse gas emissions. Higher emissions showed greater habitat reduction, as much as 80% by the end of the century.
399:; they are continuous at the base, but separated by very deep notches so that they are obviously distinct. Moreover, the caudal fin is evenly rounded. It is variable in color, from slate to reddish brown above, and paling to gray on the lower sides and underneath. Older fish are usually plain-colored, while the young often have transverse yellow bands on their sides. Their maximum length is about 4 ft (120 cm) and top weight is about 45 lb (20 kg). The IGFA world record stands at 37 lb 14 oz (17,20 kg), caught by Anders Jonasson outside Sørøya in northern Norway.
