Description:
This manuscript reports on the diets of lake herring and rainbow smelt, currently the two dominant forage fish species (fish that are food for game fishes) in western Lake Superior. Despite the pelagic nature of both these species, they have substantially different diets and hence partition the available zooplankton resources. Rainsow smelt generally selected larger taxa as food even though they are the smaller of the two fish species. Fish diets have changed relative to those found two decades earlier, likely due to changes in the Lake Superior zooplankton community over time.
