The annual fluctuation of growth of sand eel collected from 1968 to 1977 was studied in relation to the population density in Ise Bay. There was no apparent sex difference in the growth in the first and second years of life. The population was divided into two groups, age 0 and 1 groups, based on the distribution of body length. Biweekly mean body length and mean body weight for each year-class remarkably fluctuated every year. A considerable yearly variation occurring in the growth was in close connection with the fluctuation of population density of age 0 group. A highly significant negative correlation existed between the growth in weight and the population density.
