Bloater (Coregonus hoyi)
Up and down the water column they go! The smallest member of Superior's deepwater cisco complex, a bloater's slender body flashes silver with an arresting pink and purple iridescence. The guy who discovered the bloater, Dr. Hoy, proclaimed it "the most beautiful of the white fish." The shimmering beauty chases its favorite food, opossum shrimps (Mysis relicta) on a daily path up and down the water column. Bloaters maximize their growth with nutrients that the on-the-move crustacean provides, and also with an uncanny talent for growing in cold temperatures.
