Figure three shows four charts depicting the consumption of Chinook salmon at various ages and which predators are eating them at those times. It’s clear that killer whales are the largest predator of Chinook by mass, eating only adults. This potentially means that killer whales are potentially the most efficient predator by number of salmon eaten, giving them time to grow and mature. Harbor seals however, lye on the opposite side of the spectrum, consuming around 27.4 million juvenile smote. If intervention needs to take place, it should be from the place of lowest efficiency, from the harbor seals.
