Gilthead seabream - Sparus aurata
Distribution and capture Th e gilthead seabream, Sparus aurata, is a subtropical Sparidae distributed from 62°N 15°N, 17°W 43°E. It occurs naturally in the Mediterranean and the Black Sea (rare), and in the Eastern Atlantic, from the British Isles, Strait of Gibraltar to Cape Verde and around the Canary Islands (1). Gilthead sea bream are captured with traditional and sporting equipment, and so...
متن کاملFeeding, physiology and growth responses in first-feeding gilthead seabream (Sparus aurata L.) larvae in relation to prey density
21 The effects of prey density (0.1, 1 and 10 rotifer ml ) on feeding, oxygen uptake, growth, survival and energetic efficiencies in Sparus aurata larvae were investigated. Dry weights and 21 total lengths at day 15 after hatching were similar in larvae fed with 10 and 1 rotifer ml but 21 were significantly higher than in larvae fed with 0.1 rotifer ml . These differences were a consequence of ...
متن کاملA role for acidophilic granulocytes in the testis of the gilthead seabream (Sparus aurata L., Teleostei).
In mammals, a complex interaction between the immune and the reproductive systems has been described, in which testicular immune cells produce cytokines and growth factors which modulate gonad functions, while specific gonad cells influence the immune response in this organ. In this study we describe the presence of acidophilic granulocytes in the testis of the hermaphrodite teleost fish gilthe...
متن کاملAdvances in the development of microdiets for gilthead seabream, Sparus aurata: a review
Ž . The performance of microdiets MDs for larvae of marine fish is frequently improved when they are co-fed with Artemia. This suggests that nutritional factors in the live food are positively influencing the ingestion, digestion and assimilation of the MD. This paper reviews recent advances in MD development on the gilthead seabream with special emphasis on studies that isolated, identified an...
متن کاملFeeding time synchronises daily rhythms of behaviour and digestive physiology in Gilthead seabream (Sparus aurata)
Feeding cycles entrain biological rhythms, which enabling animals to anticipate feeding times and so maximize food utilization. In this article the effect of mealtime on locomotor activity, blood glucose, gastric pH and digestive enzymes was studied in two groups of seabream (Sparus aurata): one group received a single daily meal at random times either during the light and the dark period (rand...
