Species-specific foraging behavior and diets of stream salmonids: An implication for negative impacts on native charr by nonnative trout in Japanese mountain streams
Assistant Professor Peterson’s research group examined the competitive relationship between invasive trout species, brown trout and brook trout, and native white-spotted charr in Kamikochi, Nagano Prefecture, Japan. They revealed that brook trout share a strikingly similar diet and ecological niche with white-spotted charr. Furthermore, brown trout was identified as a direct predator of the white-spotted charr. These combined effects are considered contributing factors to the observed decline in the population of the white-spotted charr.
