The age and growth of rabbit fish, Siganus fuscescens were investigated from samples monthly collected in the coast of Jeju island, Korea from February to December 2012. Ages were determined from annuli in otoliths, and annuli were formed in one or two months immediately after spawning once a year. Also, main spawning period was estimated between July and August, thus rings were considered as annual marks. The von Bertalanffy growth equations estimated from a non-linear regression method were Lt=37.24 (1－e－0.33(t + 1.24)) (R2=0.92) for female and Lt=31.44(1－e－0.45(t + 1.23)) (R2=0.90) for male, and the growth between female and male was different.
