Haven't heard that before above the zebra mussel. Before anyone want to make comments about Lake Erie and thing they know better should spend a little time on Ohio DNR web site and learn the facts. I spent time of that web site for maybe close to 15 to 20 years now and read the assessment of the walleye population every year, look at the fall trawling results etc. Don't try to make one size fits all especially if if you don't understand the fishery. Do a little research, it all there on the Ohio DNR site.
