Resumo(s)
Despite much interest in the production of Senegalese sole (Solea senegalensis) in southern
Europe, weaning of this species onto artificial diets is problematic and varying results are
obtained. The aim of this study was to test two feeding frequencies during a 13-day pre-weaning
period and assess their impact on the growth and survival of Senegalese sole. Postlarvae
were fed Artemia metanauplii with a peristaltic pump every hour for 12 hours per day or twice
daily (morning and late afternoon). Both groups were suddenly weaned onto a commercial diet
for an additional 30 days. At the end of the experiment, the relative growth rate and final dry
weight were significantly higher and the survival significantly lower in the 12-hour treatment than
in the twice-daily treatment. The feeding frequency had no effect on condition factor. The incidence
of deformities was about 80% in both treatments.
