Distribution and biology of grenadiers (Macrouridae) in West Greenland waters

Abstract

During the period 1987-94, 11 bottom trawl surveys covering depths from 34 to 1497 m were conducted. Two grenadier species not previously recorded for the area, Nezumia bairdi and Gadomus longifilis, were caught bringing the number of species recorded in West Greenland waters to ten. Geographic distribution in relation to depth and temperature, abundance of the most common species, Coryphaenoides rupestris, C. guentheri and Macrourus berglax and length distributions of all species encountered were analyzed. Growth, food and length/weight relationships for selected species are also presented.
