Chronic intermittent hypoxia modulates energy metabolic pathways and improves hypoxia tolerance capacity in golden pompano, Trachinotus blochii.

Hypoxia is one of the most significant abiotic stresses affecting organisms in aquatic environments. However, dissolved oxygen in water is not always at the low concentrations that cause hypoxia, but their levels often fluctuate. Here, golden pompano (Trachinotus blochii) was subjected to low oxygen concentrations for 28 days (intermittent hypoxia, 2 h per day), and their metabolic indexes were systematically evaluated.
