Effect of continuous food supply on the oxygen consumption of young Mediterranean yellowtail (Seriola dumerili Risso, 1810)

The aim of this work was to investigate the effect of a continuous food supply on the oxygen consumption of young Mediterranean yellowtails (Seriola dumerili Risso, 1810) during the photophase period (14LL:10DD). Four groups with six fish each, weighing individually approx. 600 g, were distributed i...
