2003년 2월부터 2004년 1월까지 잔라북도 고창군 심원면 대죽도 부근에 서식하는 바지락의 성장에 관한 조사결과를 요약하면 다음과 같다. 1. 바지락의 패각에 나타난 윤문은 연1회 형성되며 윤문형성시기는 1월에서 3월사이로 조사되었다 2. 초륜 형성 시기는 19개월(1.58년)로 나타났다. 3. 각고에 대한 각장,각폭 및 총중량사이의 상대성장관계식은 각각 ${\bullet}$ SL=1.0027SH+5.812, ${\bullet}$ SW=0.5120H+1.2849, ${\bullet}\;TW=2.8x10^{-3}SH^{2.3648}$ 이었다. 4. 연령에 대한 각고와 총중량으로부터 구한 von Bertalanffy성장식은 ${\bullet}\;SH_t=42.83(1-e^{-0.4595(t-0.591)})$이고, ${\bullet}\;TW_t=20.17(1-e^{-0.4595(t-0.59)})^{2.3648}$이다.
Growth status of the Littleneck calm Ruditapes philippinarum (Adams et Reeve) in Komso Bay was investigated by 600 individuals from February 2003 to January 2004. Based on the monthly variation of marginal growth rate of the shellfish, it was suggested that ring formation occurres between January and March once a year and takes approximately 19 months (1.58 old ages) to form a complete ring. The relationship between the shell height(SH) and the total weight(TW) could be represented by the following equation $TW=2.8{\times}\;10^{-3}SH^{2.3648}$. And the relationship between the shell height(SH) and shell length(SL) as well as the shell width(SW) were represented by equations SL=1.0027SH+5.812 and SW=0.5121H+1.2849 respectively. Growth curves for shell height and total weight fitted to the Bertalanffy's equation were expressed as $SH_t=42.83(1-e^{-0.4595(t-0.59)})$ and $TW_t=20.17(1-e^{-0.4595(t-0.59)})^{2.3648.}$
