- •
Caligus rogercresseyi sea lice negatively impact Chilean salmonid farming.
- •
The aim of this study was to analyze the effects of C. rogercresseyi infestation on the metabolic responses of Salmo salar and Oncorhynchus kisutch.
- •
Plasma glucose levels changed in both salmonid species, increasing at 1–3 days post-infestation.
- •
Amino acid metabolism in liver and muscle of O. kisutch increased during infestation, indicating a higher use of the gluconeogenic pathway than S. salar.
- •
Amino acid and carbohydrate enzymes in O. kisutch activated soon after initial infestation, allowing at this species to dispose of energy substrates earlier than S. salar.
