Population estimation and interaction of non-native predators with Atlantic salmon

Possible interactions between smallmouth bass and chain pickerel (non-native predators) and Atlantic salmon smolt will be examined. Predation pressure on Atlantic salmon smolt by these non-native predators will be studied using a population estimate of smallmouth bass and chain pickerel as well as a stomach content survey of the non-native predators. Reliance on Atlantic salmon smolt for a food source by the non-native predators will be estimated based on stomach content data. Population estimates and stomach content data will provide a better understanding of how and when these non-native predators and Atlantic salmon interact. It may also indicate how these interactions can be minimized and how predation relief efforts could be most effectively utilized.
