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 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...
متن کاملZn, Cu, Pyruvate Kinase and Myosin in White Muscle of Gilthead Seabream (Sparus aurata) Fed A Zn Enriched Diet
Two groups of young gilthead sea bream were fed two different diets: a control diet containing Zn at 120 mg/kg feed and a supplemented diet containing Zn at 240 mg/kg feed. White portions of lateral muscle were analyzed for Zn and Cu concentrations, myofibrillar composition and pyruvate kinase (PK) activity in order to determine the influence of Zn on these biochemical parameters during the gro...
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 کاملSelf-selection of diets with different oil oxidation levels in gilthead seabream (Sparus aurata)
The present research looked at the ability of gilthead seabream to discriminate between two similar diets differing only in the extent of lipid oxidation. Six groups of 4 fish (254g initial wet weight) were allowed to select by means of self-feeders between two complete diets (34.5% casein + gelatin, 14.8% fish oil + soybean oil, 24.8% dextrin and 25.9% vitamins, minerals, filler and binder) wh...
