In the parlance of the Pacific Northwest of the United States, June Hogs were the largest Chinook salmon caught in the summer migratory runs of the fish. Often weighing at least 80 pounds (36 kg),[1][2] these enormous salmon were once harvested regularly each summer by First Nations peoples, sportfishers, and salmon canneries on the Columbia River and its tributaries, but have now disappeared due to the decline of salmon runs in general; today the largest Chinooks caught in the same runs are half the size.[1] The name "June Hog" derives from the seasonality of the runs and their size.[3]
