Recovery of marine mammal populations may lead to more predation on Chinook salmon

We present a meta-analysis of consumption of Chinook salmon in the NE Pacific
- •
Frequency of occurrence of Chinook salmon in killer whale studies is high (63%), and lower in pinniped studies (< 10%)
- •
Ability to discriminate Chinook salmon from other salmonids has increased over time
- •
All data (> 330 records) and R code for analysis are publicly available
