Feeding, fat deposits and growth of sand-eels (Ammodytes personatus) were examined by taking samples from the Tsu fish market from 25 th February to 29 th May 1974.
The rapid growth and accumulation of fat, in accordance with voracious feeding, was observed shortly before the sand-eels entered the dormant state they pass through in summer. Sand-eels in this state depend for their life on the nutritional accumulation gained beforehand. So it is deduced that the nutritional condition in May, shortly before the sand-eels pass into a dormant state, would have a great influence on their survival and also on the potential of the resources of Ise Bay.
