Shrimp (Pandalus borealis) length frequency distributions obtained during research surveys in Davis Strait (NAFO Subareas 0+1) from 1983 to 1987 were analyzed for age and growth. Samples were combined within year on the basis of their similarity using cluster analysis. Modal analyses were performed for males only, separating the distribution mix-tures into normal components which were interpreted as ages 1 to 6, inclusive. Mean cara-pace lengths at these ages were estimated at 8.4, 12.3, 15.7, 18.5, 20.6 and 22.7 mm, respectively. Females were separated at ages 7 and 8+ on the basis of biological charac-teristics with mean lengths of 24.9 and 26.3 mm. A comparison of results from Davis Strait with those reported from other areas in the Northwest Atlantic showed increased longevity and slower growth in the north
