Abstract

Age and growth of the blue spot mudskipper (Boleophthalmus pectinirostris) were studied using the samples caught in the mud flats of southwestern Korea during April-October, 2001. The value of the marginal index of the second actinost bone was the lowest in July and October and indicated by rings that was formed twice a year. The relationship between body weight (BW) and total length (TL) was expressed as BW=0.000005 TL3.12 (r2=0.92) for females and BW=0.000476 TL2.18 (r2=0.67) for males. Regression analysis of TL-BW between sexes showed a significant difference (P<0.01). Relationship between total length (TL) and actinost radius (R) were expressed as TL=16.9+33.4 R (r2=0.62) for females and TL= 45.8+26.2 R (r2=0.41) for males. Growth parameters, L∞, t0, and K were estimated as 165.2mm, -0.23, and 1.07 for females and 155.3mm, -0.35, and 1.39 for males.
