Définition d'un modèle d'élevage larvaire intensif pour la daurade Sparus auratus ArchiMer
Ounais-guschemann, Nadia.
This study defines rearing parameters for mass products of 30-day old post larvae. Continuous lighting (600 lux) optimizes the predatory activity and suppresses the feeding rhythm. For 4-5 mm larvae (15 days), food ingestion slows down if the prey concentration in the tank is below 5 rotifers/ml, while there is no such threshold for 6-7 mm larvae (22 days). The rotifer Brachionus plicatilis , between 100 and 200 mu m, is an adequate initial prey, it can be replaced by Artemia salina for 7-8 mm larvae (30 days). It is observed that free amino acids and essential fatty acids contents have a prominent role in larvae growth; docosahexaenoic acid (C22:6n-3) content could be determined. Finally, the development of the swim bladder is facilitated by the renewal...

First report on the triggering effect of light on the hatching mechanism of <i>Artemia salina</i> dry cysts OMA
Sorgeloos, P..
In the literature, hatching of <i>Artemia salina</i> L. dry cysts has always been related exclusively to the hydration state of the cysts. Hatching experiments with cysts from different places revealed that light in some way triggers the hatching mechanism.
