ABSTRACT Larvae of the brachyuran crab Hemigrapsus oregonensis were raised in the laboratory from broods obtained from egg-bearing females collected at a site previously contaminated by a spill of crude petroleum hydrocarbons and from a site not recently contaminated. Larvae from both sites were raised throughout development on 2 diets of the rotifer Brachionus plicatilis, one in which the rotifer was cultured on the green alga Dunaliella tertiolecta, the other cultured on the brown alga Isochrysis galbana. Percentage mortality per stage for larvae from the contaminated site was equal to or lower than for larvae from the clean site. There was no difference in duration of zoeal development nor for megalopal weight for larvae from either site on either diet. Larvae raised on rotifers fed Dunaliella showed higher mortality during the fifth zoeal stage, longer zoeal duration for stages II-V, and lower megalopal weight than did those raised on rotifers fed Isochrysis. Results indicate that previous exposure to petroleum hydrocarbon contamination during brooding has no effect on subsequent zoeal development when larvae are not directly exposed to contamination. Differences in larval response to diet demonstrate that the nutritional value of heterotrophic prey will depend upon what the prey has previously fed upon, either in the laboratory or in nature.
