Abstract: Embryo mortality was elevated in oil-affected streams during the falls of 1989, 1990, 1991, 1992, and 1993 (P less than 0.023 for all years). However, no statistical difference was observed in the falls of 1994, 1995, and 1996 (P greater than 0.473). In 1997, elevated mortalities in oil-affected streams were again seen (P=0.033). Possible causes for this result are currently being investigated. The purpose of this project is to monitor the recovery of pink salmon embryos in the field. This is the closeout year for the project.
