After decades of fish stocking decreases to balance the alewife and Chinook salmon populations, the Michigan DNR is seeing good indicators that a modest stocking increase may be warranted in Lake Michigan.

To discuss this proposal and receive public feedback, the DNR will host a virtual meeting Monday, Sept. 19, from 7 to 8:30 p.m.

“We have seen several years of good Chinook salmon growth and have a slight increase in the alewife biomass, or abundance of those fish,” said Jay Wesley, the DNR's Lake Michigan basin coordinator. “Although the alewife biomass is a fraction of what it was historically, we have a good 2021-year class and have seen up to six-year classes of alewives in our fisheries surveys – that means there are up to six different age groups in the current population of alewife." 

A "year class" refers to all of the fish of any species hatched, either through natural reproduction or through fish-rearing efforts, during that year's spawning period. 

Wesley said that a recently run predator-prey model also suggests that Lake Michigan has a good ratio of Chinook to alewife biomass, which is one of many indicators used to inform stocking decisions.

“The proposed 54% increase from 650,000 to 1 million spring fingerlings is a modest increase compared to the estimated 4.5 million wild Chinook salmon in Lake Michigan,” said Wesley. “It will allow us to increase numbers at sites like Charlevoix that contribute to the entire lake fishery and reinstate stocking sites like Ludington State Park and Fairport.”
