In the Spanish Greenland halibut fishery, grenadier are an important component in the by-catch. Their catch, catch-rate and size distribution were analyzed during the period 1991 to 1993.The importance of these species in relation to the targetted species increased in the period studied and the proportion between the two in by-catch was approximately 50%. Yields were greater during the first half year period, and increased with depth. Sizes of roundnoes were smaller to the south (3N) whereas roughead sizes were larger in this same division.
