Gene markers of dietary macronutrient composition and growth in the skeletal muscle of gilthead sea bream (Sparus aurata)

‘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...

Expression of skeletal myosin light chain 2 in gilthead sea bream (Sparus aurata, L): regulation and correlation to growth markers.

Metabolic Effects of Insulin and IGFs on Gilthead Sea Bream (Sparus aurata) Muscle Cells

Primary cultures of gilthead sea bream myocytes were performed in order to examine the relative metabolic function of insulin compared with IGF-I and IGF-II (insulin-like growth factors, IGFs) at different stages in the cell culture. In these cells, the in vitro effects of insulin and IGFs on 2-deoxyglucose (2-DG) and l-alanine uptake were studied in both myocytes (day 4) and small myotubes (da...

Normal and histopathological organization of the opercular bone and vertebrae in gilthead sea bream Sparus aurata

This study provides a comprehensive description of the tissue organization of nondeformed and deformed opercula and vertebrae from gilthead sea bream Sparus aurata juveniles by means of histological, histochemical and immunohistochemical approaches. Two types of opercular anomalies are described: the folding of the opercle and subopercle into the gill chamber, starting at the upper corner of th...

Stress and mu opioid receptor in the management of gilthead sea bream (Sparus aurata) aquaculture

The growing consumption of aquaculture products requires always new techniques to increase the production yield. Generally, the intensification of aquaculture practices is associated with a stress level rise of bred fishes. Sensitivity to stress, leading to disease, reduced growth and mortality, is higher in larvae than in adult fish. The stress induced effects can be reduced acting on opioid r...
