I. galbana, P. lutheri 및 C. simplex 3종을 먹이로 공급하며, 미세조류 종류에 따른 피조개 유생과 부착치패의 성장과 생존율 등을 비교하였다. 서로 다른 미세조류 3종을 단일 또는 혼합하여 먹이로 공급한 피조개 유생의 성장은 혼합 공급구에서 가장 빠르게 나타내었고, 단일 공급구 중에서 C. simplex 공급구에서 가장 높은 성장을 보였다. 또 유생의 생존율은 혼합 공급구에서 <TEX>$27.4{\pm}5.3%$</TEX>로 가장 높게 나타내었고, 단일 공급구 중에서 C. simplex 공급구에서 <TEX>$14.5{\pm}2.3%$</TEX>로 가장 높았다. I. galbana, P. lutheri, C. simplex 3종을 단일 또는 동일비율로 혼합한 미세조류의 지방산 조성은 EPA의 경우 C. simplex에서만 <TEX>$25.9{\pm}0.64%$</TEX>로 나타났고, 다불포화지방산(PUFA)과 n-3 HUFA 함량은 C. simplex에서 가장 높게 나타났다. 또 이들 미세조류를 먹이로 공급한 피조개 부착치패의 경우 C. simplex 공급구에서 포화지방산과 AA 함량이 유의하게 높았다. 이와 같은 C. simplex의 지방산 조성이 피조개 유생과 부착치패의 성장과 생존율의 원인으로 판단된다. 따라서 단일종으로는 C. simplex가 가장 적합하나 3종을 혼합하여 공급하는 것이 더 좋은 먹이효율을 유도할 수 있다.
