Synopsis

The 96 h LC50 tests were conducted with chum, coho and chinook salmon alevins caught in the Avacha River (Kamchatka) estuary. Coho and chinook alevins exhibited very low seawater a adaptability when compared with chum. It is likely that coho and chinook young were pulled downstream by high velocity flow during the summer freshets.
