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 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...
متن کاملHormonal mechanisms regulating hepatic vitellogenin synthesis in the gilthead sea bream, Sparus aurata.
Experiments were carried out to study in vitro the effects of 17beta-estradiol (E(2)), homologous pituitary homogenate (HPH), and recombinant red sea bream growth hormone (sbGH) on vitellogenin (VTG) secretion from cultured sea bream liver fragments. Basal secretion of VTG was found to be significantly higher in the prespawning period, compared with sea bream liver in the spawning and postspawn...
متن کاملChemotaxis of pathogenic Vibrio strains towards mucus surfaces of gilt-head sea bream (Sparus aurata L.).
Vibrio anguillarum and Vibrio alginolyticus exhibited significant adhesion to and chemotactic abilities towards mucus collected from the skin, gills, and intestine of gilt-head sea bream. Quadratic polynomial models for chemotaxis designed to estimate the influence of temperature demonstrated a differential bacterial chemotaxis depending of the source of the mucus, with the chemotaxis towards i...
متن کاملSpawning Latency Period in Hormonal Induced Reproduction of Snow trout (Schizothorax zarudnyi (Nikolskii, 1897))
Background: The breeding performance is an important parameter to evaluate the breeding success in captive condition. The optimum hormone dose in combination with latency period is desirable for getting best breeding performance in fish. Objectives: <span style="color: win...
