This study determined the effect of prey DHA on larval gilthead sea bream (GSB; Sparus aurata ) photoreceptor abundance, rhodopsin expression, and growth performance. It was carried out in a twenty-eight 400 l conical tank system that stocked with 100 viable GSB eggs/l/tank. allowed testing 4 levels rotifer DHA; 0.99 (Low; L), 1.9 (Intermediate low; I-L), 3.2 high; I-H) 12.1(High; H) mg DHA/g D...

Decorator crab Camposcia retusa is a popular marine ornamental species; however, it has never been bred previously. To establish feeding regime for C. larvae, which include two zoeal and megalopal stage, three experiments were conducted. In all experiments, ≥60% of unfed 1st (Z1) larvae survived to the next combined with orange guts observed in fed Artemia, suggesting Z1 are facultative lecitho...
