Abstract
Blackspot seabream Pagellus bogaraveo is a potential candidate species for southern European aquaculture. A 12‐week feeding trial was then conducted to evaluate the effect of dietary protein level on growth performance, body composition and feed use efficiency of blackspot seabream juveniles (22·7 g each). Five isolipidic diets (12·5%) with graded levels of protein (20, 30, 40, 50 and 60%) were hand‐distributed, twice a day, to duplicate groups of fish (120 fish per tank), until satiation. Growth (DGC), survival and feed utilization (FCR) were recorded through monthly sampling. Growth performance was significantly affected by dietary protein level (P < 0·05), and fish fed at the 50% protein level exhibited the highest final body mass. Feed conversion ratio decreased with increasing levels of dietary protein, fish fed 60% protein being the most efficient. No significant differences were found in whole body composition among treatments (P > 0·05). Financed by FCT (Project POCTI/CVT/39239/2001, PhD Grant SFRH‐BD‐14068–2003)
