ODNR studies water current’s influence on walleye hatch with Lake Erie buoy
| An Ohio Department of Natural Resources project is investigating possible causes for the decline in walleye hatch sizes in Lake Erie. As we reported earlier this month, preliminary July trawls in the lake show that the 2010 hatch will continue a nearly decade-long trend of declining stocks. While the diminishing hatch sizes are commonly..
