Solar ultraviolet B radiation (UVB) has recently been described as a relevant stressor in fish confined to aquaculture cages. In gilthead seabream ( Sparus aurata ), UVB exposure resulted decreased growth, epidermal sloughing, increased oxidative stress the skin, and induced changes behavior, physiology, immune system. Several molecular responses should accompany such detrimental effects; howev...

Territoriality, spatial exploration and social hierarchy are strictly related behaviors in gregarious fishes, often under-appreciated farms where the individuals confined within crowded spaces. In this study, we investigated role of exploration, elucidating importance time upon forming organization, territoriality gilthead seabream (Sparus aurata), using two experimental approaches. first appro...

Prolactin (PRL), a peptide hormone produced by the pituitary gland, was shown to play an important role in the modulation of the immune system of lower and higher vertebrates. To further investigate the effects of PRL on the activation of professional phagocytes of bony fish, we stimulated head kidney leukocytes and purified macrophages from the gilthead seabream (Sparus aurata L.) with various...

The aim of the present study was to evaluate effect different n-3 LC-PUFA-rich microalgae replacing FO in larval diets, on performance, biochemical composition and health gilthead sea bream (Sparus aurata). Dietary fish oil (FO) replaced with oleic acid (OA) or 3 algae products (2 commercial products: All G Rich DHA Gold, a development product: MO060). five early weaning microdiets were fed 20-...
