Identification of anadromous Arctic charr ( Salvelinus alpinus ) stocks in coastal areas of northern Labrador based on a multivariate statistical analysis of meristic data
Variation in meristic characters of northern Labrador anadromous Arctic charr (Salvelinus alpinus) was analysed using a recently developed multivariate statistical technique for meristic data. Meristic characters of 1037 specimens from seven areas were analysed. Results suggest that at least seven d...
