Abstract: abstract:Age and growth of the tile fish, Branchiostegus japonicus, was estimated by examination of the annuli in otoliths of 417 individuals. The relationship between total length (L, mm) and otolith radius (R, mm) for females was L=40.12+49.7R, for male L=35.0+54.87R. Marginal increment indicated that annulus was formed once a year between January and February. The relationship between body weight (W) and total length for female was W=2.634 × 10-6 L3.249, for male W=4.042 × 10-6 L3.169. The parameters of von Bertalanffy growth equations were estimated as L∞=425.4 mm, K=0.195/yr, to=-0.817 yr for female and L∞=471.2mm, K=0.186/yr, to=-0.831 yr for male. The spawning period was from May to November with two peaks in May to June and in September to October, respectively. The monthly changes between condition factor and gonadal indices were consistent, suggesting that spawning behavior affects condition factor. The sex ratio of the fish is close to 1:1 and the percentage of female decreased with increasing total length.
