Feeding 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 کاملGilthead 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 کاملEnvironmental Conditioning of Skeletal Anomalies Typology and Frequency in Gilthead Seabream (Sparus aurata L., 1758) Juveniles
In this paper, 981 reared juveniles of gilthead seabream (Sparus aurata) were analysed, 721 of which were from a commercial hatchery located in Northern Italy (Venice, Italy) and 260 from the Hellenic Center for Marine Research (Crete, Greece). These individuals were from 4 different egg batches, for a total of 10 different lots. Each egg batch was split into two lots after hatching, and reared...
متن کاملNutritional and hormonal control of lipolysis in isolated gilthead seabream (Sparus aurata) adipocytes.
We examined the effects of diet composition and fasting on lipolysis of freshly isolated adipocytes from gilthead seabream (Sparus aurata). We also analyzed the effects of insulin, glucagon, and growth hormone (GH) in adipocytes isolated from fish fed with different diets. Basal lipolysis, measured as glycerol release, increased proportionally with cell concentration and time of incubation, whi...
