The key mechanisms associated with the survival of Gulf toadfish, Opsanus beta, when in severe hypoxia

open access: yesJournal of Fish Biology, EarlyView.
Abstract Florida's shallow seagrass beds experience daily diurnal fluctuations in environmental oxygen, leading to hypoxic episodes (PO2 < 2 mg L−1, ~6 kPa) that have increased in frequency and intensity in recent decades. The native Gulf toadfish (Opsanus beta) have been shown to employ a suite of adaptive cardiovascular, ventilatory and metabolic ...
