The project objectives were to assess potential salmon predation impact on juvenile salmon and herring by: (1) comparing diets of adult pink salmon during their homing migrations using samples taken from surface trawls in SEAK straits and purse seines in SEAK and PWS; (2) contrasting predation incidence of these abundant pink salmon with the less abundant, more piscivorous adult coho and immature (age-1+) Chinook salmon in SEAK straits; and (3) examining potential climate mechanisms that could influence predator-prey match-mismatch by altering life history patterns of growth, migration timing, or stock-specific characteristics.
