Abstract
1) The diet and feeding ecology of embiotocid fishes around Odawa Bay, Kanagawa Prefecture, are examined on the basis of qualitative and quantative analyses of the gut contents.<br> 2) The main food items of the 0+age group is gammarid amphipods in D. viridis, gammarids and caprellid amphipods in D. temmincki and copepods in N. ransonneti.<br> 3) The amount of food intake per body weight is shown to be 2-3% in D. viridis, 2-5% in D. temmincki and 1-4% in N. ransonneti.<br> 4) The seasonal change of the food items utilized by the 0+age group of D. viridis and D. temmincki correspond fairly well to that of relative abundance of phytal animals in the Zostera belt.<br> 5) The 1+age group of D. viridis and D. temmincki utilize a wider variety of types and larger sized food items which are not always predominant in the Zostera belt.<br> 6) The food items of N. ransonneti show no seasonality and N. ransonneti does not seem to depend on phytal animals in the Zostera belt as food resources.
