The samples were collected by trawl-net in East China Sea in June, 1947. Two rings seem to be formed annually on the scale. The samples were mostly 2- or 3-year-olds, and among the rest, 1-year-olds were somewhat fewer than 4-year-olds. Their survival rate in appearance was calculated as 30% in the 3-year-olds and about 10% in the 4-year-olds.
