dc.description.abstractUnlike mammals, many fish species are indeterminate growers. Muscle growth involves hypertrophy and hyperplasia, processes that can continue during the whole life of the fish and are highly modulated. Growth hormone (GH)/insulin-like growth factors (IGFs) endocrine axis is the main intrinsic factor controlling growth. Diet composition and physical activity are important external regulators not only of the fish somatic growth, but also of muscle characteristics. Over the last years, we have been investigating in gilthead sea bream (Sparus aurata) the possibility to enhance growth using different approaches: injection of recombinant bovine GH (rBGH), moderated and sustained swimming activity or diet supplementation. We have determined biometrical parameters, hormones’ levels, gene and protein expression of growth, myogenesis, proteolysis and osteogenic gene markers in white muscle, liver or bone, and also analyzed muscle histology. In the different models we have found that an increase in body weight up to 30% can be achieved, and the ratio of circulating GH/IGF-I has appeared as a very good indicator of the growing condition. Moreover, the effects of these factors on the expression of GH and IGF-I receptors, binding proteins and specific regulators in the different tissues have been explored. All this has been performed in an attempt to understand how this complex scenario can determine the optimization of growth and quality of the fish, thus, contributing to the improvement of aquaculture productiones_ES
