Parr-Smolt Transformation of Atlantic Salmon ( Salmo salar ): Activities of Two Respiratory Enzymes and Concentrations of Mitochondria in the Liver
Hatchery-reared parr and smolts of Atlantic salmon (Salmo salar) derived from spawners of the Big Salmon, Saint John, and Penobscot rivers were analyzed for activity of two respiratory chain enzymes in liver. Cytochrome c oxidase activity was about 15-fold greater in enzyme units than succinate dehy...
