. In four experiments, performed at the Agricultural University, Wageningen and the Netherlands Institute for Fishery Investigations, the effects of attractants on feed acceptance and growth of glass eels, Anguilla anguilla L., were studied. The results show that extracts from natural food or a mixture of synthetic amino acids improve acceptance of a trout fry crumble at first feeding of glass eels. Overall results can be greatly improved by initiating the feeding behaviour of the fish by feeding cod roe for the first few days. The results also demonstrate a strong effect of the feeding level on feed acceptance. At relatively high feeding levels no significant effect of attractants could be detected.
