New information is presented on the distribution, size composition, sex ratio, maturity and growth of the Icelandic scallop (Chlamys islandica) along West Greenland. In West Greenland, populations of C. islandica are mainly distributed in the outer regions of fjords at depths between 20–60 m. They are distributed in areas characterized by strong tidal currents and populations are generally composed of large scallops in the range of 60–110 mm shell height with the majority being 75–100 mm. There is minor morphometric variation between areas. The sex ratio is generally 1:1 and they become sexually mature from 30 to 55 mm shell height at ages 4–9 years. There are small differences in shell height-at-age between males and females, but between area means vary from 58 to 68 mm at age 10 years. Seasonal and areal variations in both the muscle and gonad weights were also ob-served.
