Ecology
Marine; demersal; oceanodromous (Ref. 51243); depth range 30 - 1000 m. Subtropical; 40°S - 57°S, 76°W - 55°W (Ref. 1371)
Southeast Pacific and Southwest Atlantic: Patagonian region of Chile and Argentina, including the Falkland Islands and the Strait of Magellan.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 50.0 cm TL male/unsexed; (Ref. 1371)
Highest catches at 235 m. Females attain larger sizes than males. Larger individuals of both sexes move into deeper water. Utilized mainly for fishmeal; can be fried, microwaved and baked (Ref. 9988).
