Effects of growth rate, temperature, season, and body size on glycolytic enzyme activities in the white muscle of atlantic cod ( Gadus morhua)
Abstract In the fast‐growing Atlantic cod ( Gadus morhua ), the specific activities of the glycolytic enzymes phosphofructokinase (PFK), pyruvate kinase (PK), and lactate dehydrogenase (LDH) in white muscle were positively correlated with growth rate. For PFK and PK, season modified the relationship...
