A comparative study of blood oxygen transport in turbot and sea bass: effect of chronic hypoxia
A comparative study of blood oxygen binding and carrying capacities of turbot Scophthalmus maximus and sea bass Dicentrarchus labrax , two fish species differing in their demand for oxygen, was carried out under three levels of chronic hypoxia ( P o 2 = 93, 65 and 40 mmHg) for 40 days. Blood O 2 aff...
