Abstract
    A dry food for sole culture was developed, based on shrimp meal with starch binders. The growth rate of young soles fed with dry food was compared with growth of soles fed with fresh mussel meal. Measurements of oxygen consumption and growth were carried out with groups of soles fed different daily rations of dry food or mussel meal. Daily food intake, growth, and oxygen consumption were exponentially correlated wilh fish weight, showing a more or less similar weight exponent varying between 0.7 and 0.8. The proximate body composition of soles was determined and correlated with the condition index of the fish, in order to calculate growth in dry weight, lipid, protein, and energy. The gross food conversion efficiency reached a maximum at a daily ration in dry weight food of 4% of metabolic fish weight. The net conversion efficiency of mussel meat into growth was twice as high as the net conversion efficiency of dry food. The net protein conversion efficiency was more similar, indicating that starch in the dry food was not properly utilized by the fish.
