An analysis of the condition (Fulton’s K) of cod ( Gadus morhua) off Greenland during autumn in the period 1982–1998 is presented. The paper addresses the interannual variations in condition and attempts to relate these to variations in water temperature. No size, age, sex, maturity nor geographical differences were observed. Condition of cod was positively related to water temperature. Mean condition factor calculated from total weights for the entire period was 0.89. Hepatosomatic and gonadosomatic indices are also presented for year 1998. Overall, the condition of cod off Greenland was among the lowest observed in natural populations of this species.
