Ecopoetics Along Shorelines


May 18, 2018

Fig2 shows that Chinook populations on the West Coast increased relatively constantly from 1975-2015.  Although it shows this increasing trend, predator populations have increased too, and it appears that predators may exceed their prey in the near future, taking a toll on killer whale populations.  Results show that salmon populations have decreased recently, perhaps due to “reallocation from human harvest to marine mammal consumption”, despite salmon recovery projects from policy makers.  Based on information primarily from “coded wire tags recovered from commercial and recreational fisheries” and bioenergetics models, scientists and policymakers work together to replenish populations of Chinook and predators.
