Is white muscle anaerobic glycolysis capacity indicative of competitive ability in Arctic charr?

Abstract

Food ingestion to assess dominance status, indicated that dominant Arctic charr Salvelinus alpinus displayed significantly higher white muscle pyruvate kinase (PK) and lactate dehydrogenase (LDH) activities compared to subordinate fish [PK = 429.57 ± 76.37 v. 331.00 ± 61.73 Ug-1 tissue (P = 0.022) and LDH = 929.33 ± 61.03 v. 775.25 ± 110.96 Ug -1 tissue; (P = 0.0007)]. © 2005 The Fisheries Society of the British Isles.
