This paper reviews two studies discussing density-dependent growth using Japanese sardine data. However, the results and interpretation of these two papers indicate inconsistencies and conflict with each other. This study shows that the length of sardines in year t can be explained by the values of the three-year moving average of reproductive success in year t - 3. This indicates that the existing density-dependent growth of sardines is questionable and that environmental conditions determine the growth of fish.
