성장기 해역별 해만가리비의 총지질 함량은 8월 통영해역에서 가장 높았으나, 9월과 10월에는 감소하였고 11월에는 가장 낮은 수치로 현저히 감소하였다. 해역별 phytoplankton의 총 지질함량은 통영해역에서 가장 높은 것으로 나타나 통영해역에서의 가장 성장이 좋은 결과와 잘 일치하여 먹이생물인 phytoplankton의 총지질 함량이 해만가리비의 성장에 중요한 역할을 하는 것으로 보인다. 통영해역은 8월에 최고를, 11월에는 감소하는 경향을 나타냈다. 성장기에 있어서 해만가리비의 해역별 계절에 따른 지방산 조성중 포화지방산으로서는 16:0, 18:0가 주성분을 이루었고, 불포화지방산인 monoenoic acid는 16:1n-7, 18:1n-7, 20:1n-9, ARA (20:4n-6), EPA (20:5n-3), DHA (22:6n-3) 가 주성분이었다. 해만가리비의 성장기 (8-11월) 에 있어서 해역별 phytoplankton의 지방산 조성은 여름철인 8월에 오메가-3 고도불포화지방산은 성장이 나쁜 남해 해역이 높은데 비하여 통영과 남면해역은 낮았다.
The total oil proportion of bay scallop by areas during the growing period was the highest (2.8%) at Tongyong in August, then it decreased to 1.88% in September and 0.62% in October, and it was the lowest (0.22%) in November. The total oil proportion of phytoplankton by areas was the highest at Tongyong, where it was decreased from 5.02% in August and 3.29% in September to 2.48% in October and 1.66% in November. For the composition of fatty acid of bay scallop by areas and seasons during the growing period, the major composition was 16:0 and 18:0 as saturated fatty acid, and 16:1n-7, 18:1n-7, 20:1n-9, ARA (20:4n-6), EPA (20:5n-3), DHA (22:6n-3) as monoenic acid. TMTD (4,8,12-trimethyltridecanoic acid) was detected in a little amount as special fatty acid. For the composition of fatty acid of prey by areas during the growing period of bay scallop from August to November 1998, n-3HUFA, Omega-3 highly unsaturated fatty acid, in August was 47.11% at Namhae in slowest growth, while it was distinctively low with 34.26% at Tongyong and 14.06% at Nammeon.
