According to the growth taken from back calculation basing on scales gathered from various localities of Japan, it seems that the sardines found in Japanese waters belong to single stock. Remarkably enough the fishes obtained from Kushikino, South Kyushyu have scales in which the spans between first and second annual rings, as well as between second and third ones are found much wider than those found in scale-samples of any other localities in both third and fourth year classes. Accordingly it may be said that the stock found at Kushikino forms a local population.
