Abstract

본 연구는 말백합의 안정적인 인공종묘생산을 위해 먹이생물의 종류 및 공급량을 조사하였고, 일정기간 절식 후 먹이생물의 재공급에 따른 영향을 관찰하였다. 유생의 먹이생물은 I. galbana, C. calcitrans, N. oculata를 혼합하거나 단독으로 공급할 경우 C. calcitrans를 D형 유생 1개체당 3,000-5,000 세포를 공급하는 것이 가장 효과적이었다. D형 유생을 일정기간 절식 후 먹이생물을 공급한 경우 먹이생물을 공급한 시점부터 4일째에 평균각장 <TEX>$192.5{\mu}m$</TEX> 이상의 침착기 유생으로 성장하였다. 생존율은 절식기간이 길수록 낮아지는 경향을 보였다. The investigated amounts according to microalgae for stable supply of artificial seed of the hard clam, Meretrix petechialis and also observed the effect according to the repower of the microalgae after the specified period starvation. The stage of specimen used in the test was the D-shaped larva. The microalgae was Chaetoceros calcitrans, Isochrysis galbana and Nannochloris oculata. When the mixture of Chaetoceros calcitrans, Isochrysis galbana and Nannochloris oculata or alone C. calcitrans as food was supplied with 3,000-5,000 cells/ind., it turned to be the most effective. When the food was provided after starvation for some period, the shell length of D-shaped larva was grown to over <TEX>$192.5{\mu}m$</TEX> at fourth day from the initial feeding. The survival rate tended to be lower, the longer the starvation period.
