Calcium balance in sea bream (Sparus aurata): the effect of oestradiol-17beta.

In all teleost fishes vitellogenesis is triggered and maintained by oestradiol-17beta (E2) and is accompanied by an increase of blood plasma calcium and phosphate. The action of this hormone on calcium metabolism was investigated by treating fast-growing immature juvenile sea bream (Sparus aurata) with coconut butter implants alone (control) or implants containing 10 microg/g E2. Treatment with...

‘Molecular characterization of a gilthead sea bream (Sparus aurata) muscle

Understanding the control of piscine fatty acid metabolism is important for determining the nutritional requirements of fish, and hence for the production of optimal aquaculture diets. The regulation and expression of carnitine palmitoyltransferase 1 (CPT1; EC No 2.3.1.21) are critical processes in the control fatty acid metabolism, and here we report a cDNA from gilthead sea bream (Sparus aura...

Conservation of Some Sea Bream (Sparus aurata) Fish Populations

Some S. aurata (one wild and two farmed fish) populations namely, (D, A & K21) were genetically characterized using some DNA markers. The homogeneity value was high within each estimated fish population. The genetic dissimilarity values were calculated for reconstruction the dendrogram among them. The (D) population was distantly related from (A & K21) populations. The results suggested that, t...

Effect of low dose diuron in oxidative state on the gilthead sea bream Sparus aurata

This study investigated effect of repeated exposure to low doses of diuron in gilthead sea bream by measuring the activities of the following antioxidant enzymes: Superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX), glutathione reductase (GR), glutathione transferase (GST), and DT-diaphorase (DTD). Examination of the lipid peroxidation (malondialdehyde contentMDA) and gluco...

Parathyroid hormone-related protein: a calcium regulatory factor in sea bream (Sparus aurata L.) larvae.

The effects of an N-terminal peptide (amino acids 1-38) of Fugu parathyroid hormone-related protein (PTHrP 1-38) on calcium regulation of larval sea bream were investigated in seawater (36 per thousand) and after transfer to dilute seawater (12 per thousand). Exposure to PTHrP 1-38 evoked a 1.5-fold increase in calcium influx in both full-strength and dilute seawater. Calcium influx in dilute s...
