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

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 U g−1 tissue (P = 0·022)...

Zusammenfassung:	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 U g−1 tissue (P = 0·022) and LDH = 929·33 ± 61·03 v. 775·25 ± 110·96 U g−1 tissue; (P = 0·0007)].
