Injury to salmon eggs and preemergent fry in Prince William Sound. Fish/shellfish study number 2. Exxon Valdez oil spill, state/federal natural resource damage assessment final report
Technical Report

OSTI ID:371069
Pink salmon embryo mortality was elevated in oil contaminated streams during the falls of 1989, 1990, and 1991. Increased embryo mortality was detected in the lower intertidal zones in 1989 while elevated mortalities were observed at the highest intertidal zone in 1990. These findings were consistent with how stream oiling was expected to take place: all intertidal zones were contaminated in 1989 with the remaining oil being deposited in the highest intertidal zone in 1990. Embryo mortality was significantly higher in all zones for the oil contaminated streams in 1991. No difference in embryo to preemergent fry survival was detected for the 1989, 1990, or 1991 brood years.
