Initial larval stocking density, prey density, daily prey ration and light conditions (light intensityand photoperiod) were tested for common dentex larval rearing under experimental conditions. Experiments continued until the ¢rst peak of larval mortality. The best results in larval survival were obtained with an initial stocking density of between10 and 40 larvae L1, fed with at least10 rotifersmL1, maintaining ratios of 500^1000 rotifers larva1, with one or two adjustments of prey density per day. The use of more than 2000 rotifers larva1 or three daily adjustments of live prey density had negative e¡ects on larval survival. The best light conditions for common dentex larval rearing were found using a photoperiod of 24 h L:0 h D and an intensity of at least 3.4 mmolm2 s1.
