Aggression of individual female sockeye salmon Oncorhynchus nerka in Hansen Creek, Alaska, was unrelated to body size or density but it decreased over the last 7 days of life from an average of 8·89–1·47 counts 15 min −1 . In addition, as females neared death they tended to use less violent forms of aggression.
