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 analysis of formed teice a year. The relationship between body weigt (BW) and total length (TL) was expressed as BW=0.000005 $TL^{3.12}\;(r^2=0.92)$ for females and BW=0.000476 $TL=^{2.18}\;(r^2=0.62)$ 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 $(r^2=0.62)$ for females and TL=45.8+26.2 R $(r^2=0.41)$ for males. Growth parameters, $L\infty,t_0$ and K were estimated as 165.2 mm, -0.23, and 1.07 for females and 155.3 mm, -0.35, and 1.39 for males.
