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)].
