Abstract
    This study describes feeding rhythms in juvenile sole (0- and I-groups) and differences in choice of prey according to age and feeding time. In the same biotype, 0-group fish select amphipods or young opisthobranchs, whereas I-group fish eat chiefly polychaetes such as Pectinaria koreni. The daily food consumption for juvenile soles in the field (T = 19.8°C) is estimated at 7% body dry weight in 0-group and probably less in I-group. When compared with estimates from previous methods or models, these rations are intermediate between estimates from Kuipers' method, with a gastric evacuation rate (R) per hour representing three times the amount of food in the stomach, and those from Elliott & Persson's model with R value around 1.46.
