Comparative effects of long-term hypoxia on growth, feeding and oxygen consumption in juvenile turbot and European sea bass
When juvenile turbot Scophthulmus maximus and sea bass Dicentrarchus labrax were fed to satiation, growth and food intake were depressed under hypoxia (3.2 +/- 0.3 and 4.5 +/- 0.2 mg O-2 l(-1)). However, no significant difference in growth was observed between fishes maintained in hypoxia and fed to...
