Three-spined sticklebacks are small, green and brown fish with spines that run along their backs. In Lake Iliamna in the Bristol Bay region, three-spined sticklebacks eat the same plankton that juvenile sockeye salmon rely on to grow.This year, researchers from the University of Alaska Fairbanks plan to run some experiments there to better understand sockeye’s small, spiky competition, and if warming waters might give them a competitive advantage.
