전라남도 광양시 송도 주변해역에서 2000년 12월에 형망에 의해 채집한 농조개의 연령과 성장을 조사하였다. 연령형질은 패각을 사용하였으며, 윤문은 패각에 나타난 불투명대에서 투명대로 이행하는 경계로 하였다. 출현한 개체의 각장은 13.1-44.2mm이었고, 평균은 19.6mm이었으며, 연령은 2세까지 출현하였다. 각장 (SL) 과 각고 (SH) 간의 상대성장은 SL = 0.2105 ＋ 1.7569 <TEX>$\times$</TEX> SH이었고, 각장 (SL)과 전중 (TW) 간의 상대성장은 TW = 2.5824<TEX>$\times$</TEX> <TEX>$10^{-4}$</TEX> <TEX>$\times$</TEX> S <TEX>$L^{2.6769}$</TEX>이었다. Von Bertalanffy 성장식은 <TEX>$L_{t}$</TEX> = 81.46(1-e <TEX>$^{-0}$</TEX>.20(t+1.19)/), <TEX>$W_{t}$</TEX> = 33.68(1-e <TEX>$^{0.20(t+1.19)}$</TEX>)<TEX>$^{2.6769}$</TEX> 추정되었으며, 극한 각장 ( <TEX>$L_{\infty}$</TEX>) 은 81.46 mm, 성장계수 (K) 0.20/year 이었다. 0.20/year 이었다..
The age and growth of the short-necked clam, Paphia undalata, was investigated from 546 samples randomly collected in December 2000 in Kwangyang Bay, Korea. Ages were determined from ring radius of shell and the maximum age was observed to be 2 years. The relationship between shell length (SL) and shell height (SH) of Paphia undalata was SL = 0.2105 ＋ 1.7569 <TEX>$\times$</TEX> SH (<TEX>$R^2$</TEX>= 0.98), and the shell length (SL)-total weight (TW) relationship was TW = 2.5824 <TEX>$\times$</TEX> 10<TEX>$^{-4}$</TEX> <TEX>$\times$</TEX> S <TEX>$L^{2.6769}$</TEX> (<TEX>$R^2$</TEX>= 0.92). The von Bertalanffy growth parameters were estimated by the non-linear method, with values as follows: <TEX>$L_{\infty}$</TEX> = 81.46 mm, K : 0.20/year, <TEX>$t_{0}$</TEX> = -1.19 year. The von Bertalnanffy growth equation was <TEX>$L_{t}$</TEX> = 81.46(1- <TEX>$e^{-0}$</TEX>.20(t+1.19)/), <TEX>$W_{t}$</TEX> = 33.68(1- <TEX>$e^{-0}$</TEX>.20(t+1.19)/)<TEX>$^{2.6769}$</TEX>.
