Effects of oil exposure on pink salmon, Oncorhynchus gorbuscha, alevins in a simulate
By Adam Moles, Malin M. Babcock, Stanley D. Rice
Marine Environmental Research, Volume 21, Issue 1, 1987, Pages 49-58, ISSN 0141-1136, DOI: 10.1016/0141-1136(87)90073-0.
Pink salmon, Oncorhynchus gorbuscha, alevins (5 and 60 days after hatching) were continuously or intermittently exposed for 30 days to the water-soluble fraction (WSF) of Cook Inlet crude oil in fresh water or in a simulated freshwater-seawater cycle. Alevins exposed to 0[middle dot]7-2[middle dot]4 mg/liter WSF in the simulated tidal cycle were more sensitive to oil, had reduced yolk reserves, and accumulated more hydrocarbons than did alevins exposed to the same concentrations in fresh water. Alevins in fresh water were more sensitive to continuous than to intermittent exposures. In all exposures, 60-day alevins were more severely affected than were 5-day alevins.
