Several state agencies in the region (IL, IN, MI, WI) will reduce the amount
of salmon stocked in Lakes Huron and Michigan next year. The change is
designed to help the alewife population recover. Alewives are the salmon’s
main food source, but as the Great Lakes Radio Consortium’s Peter Payette
reports some biologists think helping the alewife will hurt native fish:
The total number of salmon stocked in the two lakes will be cut by more than
a third next year. The state agencies that manage the stocking programs say
there was widespread support for the decisions, but one dissenting voice was
the Chippewa Ottawa Resource Authority, or CORA.
CORA supports recovery of native fish species like the Lake trout. Mark
Ebener is a fishery Biologist with CORA. He says you can’t protect
alewives and expect lake trout to do well.
“So you have to commit to one or the other. Instead of what the states are
going to do, and what Michigan is going to do, it’s going to protect alewife
by reducing stocking so they can have healthier salmon, but at the same time
it’s going to say, ‘Well tribes we still want you to support Lake trout
rehabilitation and we still support it and think it’s still feasible.'”
Female lake trout that have a diet heavy in alewives can develop a nutrient
deficiency. It causes most of their young to die soon after birth.
