Ongoing project: Mysis ecology in the Great Lakes

Toby Holda (Funded by EPA)

Mysids are an important native species in all the Great Lakes. Understanding mysid ecology is an essential component of understanding these systems as the species is both a major predator on zooplankton and a major prey for alewife, smelt and native coregonids. Even so, they are not well studied and there are multiple questions about mysid ecology that remain unanswered. The following four studies are currently in writing or analysis stages: 1) a decade of mysid target strengths in the Great Lakes and Finger Lakes 2) spatial patterns and population demographics of Lake Ontario mysids in 2013, 3) temporal trends in mysids abundance in the Great Lakes, and 4) mysid fecundity and life history across lakes of varying trophic state and community assemblage. Some potential future topics include diet and condition of mysids in different community assemblages and lakes.
