Efforts to increase the Lake Michigan sturgeon population, which plummeted from more than 5 million fish in the 1800s to less than 5,000 today, will play out in the Muskegon River and other rivers that flow into the lake, said Ed Baker, a fisheries research biologist at the DNR's Marquette fisheries station.Baker serves on the fishery commission's Lake Michigan Committee, which oversees fish management issues in the lake.
"Interest in lake sturgeon has been building for 10 to 15 years," Baker said.

Baker said the fishery commission's involvement in sturgeon restoration could reap huge benefits for Michigan rivers in about 20 years.He said fish management agencies must proceed slowly to avoid creating large numbers of inbred sturgeon, which could be biologically disastrous.

Vecsei's study of the Muskegon River's sturgeon population will play a major role in determining whether more sturgeon are stocked in the river in the future, Baker said.
Because a previous state study deemed the Muskegon a high priority river for sturgeon rehabilitation efforts, Baker said there is a good chance more of the fish will be stocked in the Muskegon in the future.
Before that happens, however, scientists must determine if the 100 or so adult sturgeon that are native to the Muskegon River have become too inbred to support a larger, healthy, population.If too many of the fish are in-bred, Baker said the state would need to import sturgeon from elsewhere to boost the Muskegon's struggling sturgeon fishery.

Baker said he is betting on a much larger sturgeon population in the river, but not before 2020.
"For all the work we're doing now, we won't see the results for 20 years down the road," he said.
