Water- Control Structure on Lake Erie
Constructed water-control structure connecting a managed pool to Crane Creek wetland (Lake Erie). Structure allows critical fish passage between Lake Erie and the previously diked wetland.
Masters student Lila Warren documented that muskellunge in her study rivers were reproducing all by themselves and hatchery fish, in all likelihood, do not need to be stocked to sustain the fishery.
linkBiologists in North America have been studying the effectiveness of fish stocking programs ever since fish were artificially spawned, reared, and stocked in the late 1800s.
