코끼리조개의 서식생태를 알기 위하여 강원도 양양군 인구연안의 코끼리조개 서식장에서 서식 환경 및 생태학적인 시험을 실시하였다. 코끼리조개 서식지의 저층수온 연변화 5.6~$17.5^{\circ}C.$. 였으며, 염분은 32.27~34.22${\textperthousand}$로 연중 안정된 분포를 보였으며, 용존산소는 5.15~7.27 ml/l 범위였다. 서식 저질은 3.0~4.0 의 미세사질이 49.20%, 2.0~3.0 의 세사질이 31.87%로 미세사질과 세사질의 입자가 대부분을 차지하였다. 강원연안에서 채집 조사된 코끼리조개의 각장 조성은 70~135 mm(평균 107.70 mm), 중량 조성은 50~550 g(평균 299.63 g)이였다. 각장 (SL)과 전중량(TW)의 관계는 TW=$1.4446{\times}10^{-3}SL^{2.6067}$의 지수곡선식으로 나타났다.
For ecological studies on the habitat of geoduck clam, Panope japonica caught at the coastal water of Kangwon province located in the East of Korea. The annual water temperature of the geoduck's fishing grounds was ranged from 5.6 to $17.5^{\circ}C.$. The salinity was not so fluctuated showing from 32.27 to 34.22${\textperthousand}$, and dissolved oxygen was ranged 5.51 to 7.27 ml/l. Sediments where geoduck was distributed chiefly was consisted of very fine sands of 3.0 to 4.0 phi (49.2%) and find sand of 2.0 to 3.0 phi scale (31.87%). The shell length of geoduck was measured 70 to 135 mm (mean : 107.70mm) and the weight was 50 to 550g (mean : 299.63g). The total weight (TW) against the shell length (SL) could expressed as the regression equation as TW=$1.4446{\times}10^{-3}SL^{2.6067}$.
