Abstract

Based on samples of Atlantic salmon smolts from 13 geographically distinct home rivers, stocks from North America and Europe can be distinguished by morphometric character sets using discriminant analysis procedures. Character sets require morphometric measurements of total length, standard length, predorsal length, dorsal to adipose, head length, postorbital length, and left pectoral length. quadratic discriminant analysis was determined to be the most appropriate technique to classify the salmon smolts as either European or North American in origin. The analysis of the morphometric characters provided strong statistical seperation between areas. A classification of groups yielded 99.65% correct classification between European and North American stocks.
