Abstract

The ages of sandfish, Arctoscopus japonicus sampled from the eastern sea of Korea, were determined by the transverse section method of otoliths. Ages were assigned to every individual according to the number of opaque zones, and then fitted to the von Bertalanffy growth equation. Estimated equations were Lt=-e-0.2976(t+) for females and Lt=-e-0.2917(t+1.2087)) for males, where t is age (year) and Lt is body length (mm) at age t. These two equations were significantly different and the body length of females calculated from the equation was larger than that of males except at 1 year old.
