Abstract

During the period 1987-94, 11 bottom trawl surveys covering depths from 34 to 1 497 m were conducted at West Greenland. Tw grenadier species not previously recorded for the area, Nezumia bairdi and Gadomus longifils, were caught bringing the number of species recorded in West Greenland waters to ten. A significant amount of new information on grenadier species previously recorded was also collected during the surveys. Geographic distribution in relation to depth and temperature, abundance of the most common species, Coryphaenoides rupestrisCoryphaenoides güentheri and Macrourus berglax and length distributions of all species encountered were analyzed. Growth of C. rupestris and M. berglax, food of C. rupestrisM. berglax (in relation to time of the year and predator length), C. güentheri and Coryphaenoides brevibarbis, length/weight relationships for C. rupestrisC. güentheri and M. berglax are also presented. Further, relationships between total length and pre-anal fin length for Trachyrhynchus murrayi and all species mentioned above, except G. longifilis, and maturation of C. rupestris and C. güentheri are given. The available information about three grenadier species not observed during the surveys but previously recorded from the area, i.e. Nezumia aequalisCoryphaenoides armatus and Coryphaenoides carapinus, is summarized.
