The oceans contain a much higher percentage of oxygen (34 %) than the atmosphere (21 %).
Surface waters have oxygen concentrations are in equilibrium with the Earth's atmosphere. Also, colder waters hold more oxygen than warmer waters.
The global oceans have warmed during global warming. Expect reduced oxygen levels and the oxygen minimum zones to expand in our oceans.
So, good luck for this fish ... in its habitat.
