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 × SH (R2 = 0.98), and the shell length (SL) - total weight (TW) relationship was TW ＝ 2.5824 × 10-4 × SL2.6769 (R2=0.92). The von Bertalanffy growth parameters were estimated by the non-linear method, with values as follows: L∞＝81.46 mm, K＝0.20/year, t0 ＝ -1.19 year.
