Current Studies

Pelagic Fish Dynamics in Lakes Michigan and Huron

This project is focused on identifying and measuring key ecological parameters of the pelagic fish communities of lakes Michigan and Huron, the third and second largest of the Great Lakes by area. This study has developed from one focused on providing annual measures of abundance of key forage fish like alewife, rainbow smelt, and bloater, that were complementary to bottom trawl data to one focused on understanding the lakewide patterns in abundance, distribution, life history, and interactions of these fish. Sampling is conducted using scientific echosounders and a variety of trawls and limnological samplers. The surveys represent the only annual lakewide fisheries surveys in Great Lakes and are collaborative in nature, with sampling conducted by U.S.G.S., Michigan Department of Natural Resources, and U.S. Fish and Wildlife Service. Data from this project are for both research and management. Data from this study are used to inform decisions made about stocking rates for economically important sport fish like Chinook salmon as well as to inform harvest quotas for species like bloater.
