Excess post‐hypoxic oxygen consumption in Atlantic cod Gadus morhua

Atlantic cod Gadus morhua experienced oxygen deficit ( ) when exposed to oxygen levels below their critical level ( c . 73% of p crit ) and subsequent excess post‐hypoxic oxygen consumption ( C EPHO ) upon return to normoxic conditions, indicative of an oxygen debt. The mean ± s.e . C EPHO : was 6·9...

Description
Summary:Atlantic cod Gadus morhua experienced oxygen deficit ( ) when exposed to oxygen levels below their critical level ( c . 73% of p crit ) and subsequent excess post‐hypoxic oxygen consumption ( C EPHO ) upon return to normoxic conditions, indicative of an oxygen debt. The mean ± s.e . C EPHO : was 6·9 ± 1·5, suggesting that resorting to anaerobic energy production in severe hypoxia is energetically expensive.
