Summary Two different feeds in the initial period of adaptation of glass eels ( Anguilla anguilla ) to artificial food were examined. The difference between the experimental groups lay in the protein source: that of group A consisted of 50% fish meal and 50% chicken meal, and that of group B of fish meal alone. The mean weight of Gr. A was higher than that of Gr. B at the end of the experiment, and the percentage of larger elvers was higher (29%) than in group B (26%). It is concluded that 50% of the fish meal can be replaced by chicken meal, which is much cheaper in Israel and may also produce a slightly higher yield.
