Objective

Efforts are underway to re-establish Arctic grayling (see Michigan Arctic Grayling Initiative), a native species that was extirpated from Michigan by 1936. Alan Mock, a graduate student working with Dr. Carl Ruetz, is assessing streamside egg incubators in Manistee River tributaries to support the reintroduction effort. The research uses rainbow trout eggs as surrogates for Arctic grayling, which are not yet available to use in Michigan. Alan’s research, building on a “pilot” study conducted in 2017, suggests that streamside incubators can work well in Michigan. His research, which will be completed in 2019, is funded by the Little River Band of Ottawa Indians.
