Metabolic fuels in developing cod and turbot embryos and larvae
Aerobic metabolic rates of embryos and larvae of Atlantic cod (Gadus morhua) and turbot (Scophthalmus maximus) were measured and used stoichiometrically to balance the substrates, in the form of free amino acids (FAAs), proteins and lipids, that quantitatively disappeared during development.

Aerobic metabolic rates of embryos and larvae of Atlantic cod (Gadus morhua) and turbot (Scophthalmus maximus) were measured and used stoichiometrically to balance the substrates, in the form of free amino acids (FAAs), proteins and lipids, that quantitatively disappeared during development.

Turbot, however, utilize different substrates at separate stages of development. FAAs are predominantly burned during the embryonic stage, while lipids are burned during the yolk-sac stage. From the time of first-feeding, proteins are recruited from body stores and catabolized.
