摘要：The observed the toxic efect of WSF (Water Soluble Fraction) on development time. development rate. atta- chment rate,survival rate and growth of the larva during the early stage of the Pacific oyster,Crassostrea gigas. The time required early juvenile from the frilized eggs exposed to crude oil(WSF) was about 13 hours in conrol group. But that of the crude oil dose group lakes 12 hours. with shorter compared to control group. Development and atachment rate of the oyster significantly higher in 0.4 and 0.8 mg/L WSF compared to control group(P< 0.05) but significanuly lower more than 1.6 mg/L WSF (P< 0.05). Survival rate of the oyster larva significantly higher in 0.4 and 0.8 mg/L WSF compured 10 control group (P< 0.05) but significandly lower more than 2.4 mg/L WSF (P< 0.05). Survival rate of spot showed no significantly difference compared to control group (P> 0.05). Shell growth of the oyster were significantly lower more than 1.6 mg/L WSF compared control group (P < 0.05). The effeet coneentration of crude oil showed that more 0.4 mg/L in development and allachment rate and more 1 .6 mg/L in growth. Also,chronie exposure of crude oil even efect also in low concentration.
