Aplicability of sustained swimming for gilthead seabream (Sparus aurata) fingerlings farming

Abstract

Trabajo presentado en Aquaculture Europe 2014, celebrado en San Sebastián (España) del 4 al 17 de octubre de 2014Fish growth is strongly influenced by environmental and nutritional factors. So, the optimization of culture conditions can help maximize fish growth, particularly with regards to their skeletal muscle. Moderate and sustained activity has been used to improve growth rate and feed conversion efficiencies in fish. In many fish species, swimming activity changes the amount and proportion of nutrients used as energy source and the aerobic capacity of the swimming muscles. Both aspects, diet composition and dynamic muscle metabolism, were determinants of the growth improvement observed in gilthead sea bream submitted to moderate activity (Martin-Pérez et al., 2012; Felip et al., 2013). The aim of this study was to analyse the effects of five weeks of sustained activity on growth parameters, muscle metabolism and regulatory factors in the early period of gilthead sea bream farming.Peer reviewe
