| 内容記述 | The growth increment of otolith were validated to establish the daily age determination method for chika Hypomesus japonicus. Newly hatched larvae have a pair of sagitta of ca. 12.5μm radius. Sequential samplings of fish of known ages demonstrated that the number of days after hatching and the number of sagittal increments outside 12 μm radius presented a linear regression with slope 1.00. The slope is not significantly different from 1 (p > 0.05), suggesting a daily deposition of the increment in sagitta. This was supported by alizarin complexone marking of otoliths. The growth speed of the body length and otolith radius of larvae changed after 20-25 days old. The growth of body length before 20-25 days old was faster than that after 20-25 days. On the other hand, the growth of the otolith radius showed an opposite trend. The change of growth appeared to coincide with the formation of the caudal fin, i.e. the acquirement of swimming ability. | |||||||||||
