Abstrakt:	The water soluble fraction (WSF) of crude oil was tested against Macrobrachium macrobrachion and Macrobrachium vollenhovenii, at 2, 4, 6, 8 and 10 mg/L in glass aquaria stocked with ten animals for 96 h under observations for changes. Moribund swimming, restlessness, respiratory difficulties, depigmentation and mortalities were observed in the WSF exposure groups, but not in the controls. LC values were estimated at 5 ± 1.76 and 4 ± 1.76 mg/L for M. macrobrachion and M. vollenhovenii respectively. There was no significant difference in mortalities between the two species ( p > 0.05), leading to the conclusion that the WSF of crude oil in the Nigerian coastal waters may be equally toxic to M. macrobrachion and M. vollenhovenii.
