Age and growth of the short-necked, Ruditapes philippinarum were collected from Goheung coast in Korea.
Relative growth equations among SL, SH, SW and TW of Ruditapes philippinarum were ranged from 0.8059 to
0.8859. The ring radius were estimated from a von Bertalanffy method with the values of SL1.58 = 12.51 ± 2.55 mm,
SL2.58 = 20.27 ± 3.08 mm, SL3.58 = 26.90 ± 2.49 mm, SL4.58 = 31.35 ± 3.62 mm, SL5.58 = 35.45 ± 3.54 mm, SL6.58 =
38.78 ± 4.04 mm. Back calculated total weight at the formation of annual ring on the shell of Ruditapes
philippinarum with the values TW1.58 = 0.35 g, TW2.58 = 4.62 g, TW3.58 = 5.84 g, TW4.58 = 6.71 g, TW5.58 = 7.50 g,
TW6.58 = 8.14 g. Growth curves for shell height and total weight fitted to the von Bertalanffy equation were
expressed as:
SLt = 51.01(1-e-0.1738(t+1.07))
TWt = 11.65(1-e-0.1738(t+1.07))2.9519
