The purpose of the present study is to know the reproductive characteristics of Korean Amphioctopus fangsiao focusing on the sex ratio, fecundity, group maturity and egg size for management of the species resource effectively. The sex ratio (female:male) of A. fangsiao was 1:0.7 (female 58.9%) showing predomination of female. The fecundity ranged from 195 eggs at 37.4 g to 1,295 eggs at 214.3 g of body weight. The relationship between total weight (TW) and fecundity (F) was F = 4.490TW1.023 (r2 = 0.80) and fecundity increased with body weight.
