As Jason mentioned Brian's book is awesome. In my opinion, it is the absolute best book out there for nerds like us. It's very welcoming to the amateur fish enthusiast. Each species account not only has everything you would normally expect from a field guide or "Fishes of" book, but also has some unique features. The most valuable is probably " Best sites", where it names streams where you have a high probability of finding a given species. There is also a chapter on observing and collecting native fish.
Every Ohio fish nerd needs a copy, and nerds from the rest of the country ought to get one too.
Logperch, blackside, sand, johnny, greenside, and orangethroat darters should all be local to you. Rainbow and fantail darters are pretty close if not local, not sure exactly where in northwest Ohio you are.
The only dace in your area are blacknose, but there are quite a few nice shiners and minnows up your way. Some notable species are redfin shiner, spotfin shiner, and emerald shiner. Bluntnose minnows and central stonerollers would be a challenge NOT to find.
So these fish and more are in your area. The trick now is to learn what type of habitat each prefers. Bluntnose minnows and central stonerollers for example just don't care, you'll find them everywhere. You can find johnny, greenside and orangethroat darters in small streams. You can find johnny, and greenside darters in large streams, but you will almost never find an orangethroat anywhere but a small headwater stream in Ohio. Now in some places, Oklahoma comes to mind, orangethroat darters occupy large streams. Obviously sand darters need sand, but they also prefer bigger water. You really won't see them too much outside the main stem of the Maumee in northwest Ohio. Most darters like riffles, but not all. Sand darters, johnny darters and blackside darters have different habitat preferences. The sand darter is the obvious exception. Johnny darters prefer sandy areas adjacent to riffles. Blacksides would rather be hunkered down in a root wad in a sluggish area. Just scratching the surface here.
So depending on the habitat preference and habits of your target species you can choose your sampling method. Microfishing is perfect for OSS, and probably the only legal way to collect them. Kind of a grayish area there. Dipnetting works great in small streams and in vegetation. Dipnets also work well in larger streams if you set up downstream of a rock and flip it. Hopefully chasing whomever is home into your net. You can't beat a seine in larger water. Minnows and shiners and other quick fish are much easier to collect with a seine. Each method has various techniques. Honestly, writing this is reminding me of how much there really is to learn about something that appears so basic. Again just scratching the surface.
Laws. Important to educate yourself on these. I expect since you are microfishing for OSS, you have a handle on that already.
This native fish thing really adds another dimension to fish keeping. I hope this helps a bit.
