Parr–smolt transformation of a nonanadromous population of Atlantic salmon ( Salmo salar) in Norway
Morphological and physiological indices of parr–smolt transformation of fish from anadromous and nonanadromous hatchery-reared populations of Atlantic salmon (Salmo salar) were compared. Both anadromous and nonanadromous Atlantic salmon showed a complete smolt colouration and had a similar high gill...

Summary: | Morphological and physiological indices of parr–smolt transformation of fish from anadromous and nonanadromous hatchery-reared populations of Atlantic salmon (Salmo salar) were compared. Both anadromous and nonanadromous Atlantic salmon showed a complete smolt colouration and had a similar high gill Na + ,K + –ATPase activity (significantly (P < 0.05) different from that of parr), indicating both morphological and physiological aspects of parr–smolt transformation. The evolutionary stability of the parr–smolt transformation of nonanadromous Atlantic salmon is discussed. |
