Association between the Regulatory Locus PGM-1r * and Life-history Types of Juvenile Atlantic Salmon ( Salmo salar )
We sampled three juvenile life-history types of Atlantic salmon (Salmo salar) from Western Arm Brook, Newfoundland, to test whether a regulatory gene variant PGM-1r*b is associated with accelerated life-history development. Seven nonmigratory parr populations from the Miramichi River, New Brunswick,...
