Marine Growth and Morphometrics for Three Populations of Atlantic Salmon from Eastern Maine, USA
Abstract Significant differences in growth and prespawning body morphology were detected among three stocks of Atlantic salmon reared in a common marine environment. Smolts originating from river‐specific broodstock of the Machias, East Machias, and Dennys populations were reared at two marine net‐p...
