Lure selection for the Little Miami River

I think that one reason river fishermen dont painstakingly match the hatch with exact copies of the forage that bass eat is that rivers are so daggone complicated. In the LMR over a hundred different species of fish have been recorded and most of them are small fishes that could serve as bass food. And the abundance of these can vary wildly over the 110 mile plus length of the river. But since the Little Miami is designated a National Wild and Scenic River it has been studied rather extensively. Sampling surveys over the years have shown definate trends that can help you with your lure selection depending on where you are fishing in the river. Many minnow species like the central stoneroller and the various darters and shiners are found throughout the river but the population densities of each are different in different sections of river. In the lower LMR, say from Loveland/Milford to the Ohio River, shiner species such as the emerald shiner greatly outnumber other small fishes. So what does this mean? Well, shiners have a completely different shape and profile than other small fishes. They are long with a thin profile and look slightly flat being taller than they are across and silvery in color. In other words alot like classic floater diver minnow plugs such as the Rapala or AC Shiner. In the lower river you might want to fish soft plastics with this profile too such as the Mister Twister Sassy Shad. Shiners also spend alot of time in open water and close to the surface so topwaters like the pop-r are also great where shiners are common. Also the closer to the Ohio the more shad you will find. In the middle reaches of the LMR you begin to find higher and higher numbers of darters in every survey till they become the most common small fishes found on some stretches. Darters are very very colorful and on average smaller than shiner species. Darters also spend most of their time under and around rocks in swifter sections of the river. This is why rock cover becomes more important as you progress upstream and sandy gravely cover less so. Also riffles produce better in the middle LMR than the upper or lower LMR. Lures in brighter patterns with a bit of red or orange produce well in the middle LMR. Instead of a silver rapala like you threw in the lower LMR, a slightly rounder bait like a smaller rebel minnow in a "rainbow trout" pattern might be a better place to start. At the top of the middle LMR, say from Fort Ancient to the Narrows, the number of darters and shiners equals out somewhat with more plain minnows like the stoneroller than anything else. Here it becomes an anything goes affair dependant more on where you are fishing, a riffle might be full of darters but next to a pool with shiners, chubs and minnows in it. In this stretch carrying a wide lure selection can really pay off. Further upstream the river becomes a minnow factory with high numbers of darters and minnows such as the stoneroller. In some pools the number of stonerollers is staggering, well into the thousands. Here generic minnow lures like inline spinners and metalflake grubs really shine. These are just general guidelines and you might find smallies feeding on darters in the lower LMR and on shiners in the middle LMR but it gives you somewhere to start. The particular spot you are fishing is just as important as the section of river. If your fishing a riffle you might want to fish a bottom hugging smaller brighter lure while a bigger silvery plug might be the ticket in a big pool. Some common small fishes of the LMR... Central Stoneroller The most common small fish in the LMR, Stonerollers are stout brownish gray minnows with short, rounded fins. The snout is bluntly rounded and projects beyond the nearly horizontal mouth. Their mouth is always white in color. Males during breeding season have some orange and black on fins, large pointed bumbs on their head, and orange eyes. Stonerollers spawn in spring between March and the end of May. Males dig spawning beds just above or below riffles and aggressively chase other males away. The eggs are sticky and become lodged in the gravel and the nests abandoned prior to hatching. While they can reach seven inches most stonerollers are around three or four inches in length. Stonerollers feed by scraping algae from rocks on the riverbottom. The LMR is also home to other minnow species such as the tonguetied, suckermouthed, bluntnosed, fathead, and bullhead minnows. These are some of the most common small fishes in the pools of the river. Shiners The LMR is home to something like fifteen or sixteen different species of shiners. Shiners typically have a long thin profile and look slightly flat being taller than they are across. Shiners as a whole tend to hang out in open water like pools and often high in the water column. Shiners typically eat tiny insects and other various aquatic invertebrates, and terrestrial insects that fall in the water or fly just above the surface. Often when it is still and wind is not blowing you can see them dimpling the surface feeding on tiny insects like midges. Most shiners are three to five inches long but a few can reach up to ten inches in length. Darters The LMR is home to around a dozen different species of darters. Darters run two to four inches in length for the most part and are among the most colorfull fish you will ever see. When breeding most darters become very bright with fins edged in orange or red and bright blues as well as spots or bands of bright colors on their bodies. Darter species on the LMR include the greenside, rainbow, fantail, least, johnny, and orangethroat darters as well as the logperch, varigate, banded, channel, blackside and slenderhead darters plus maybe an additional one or two that I may be missing. Most darters inhabit swifter riffles in the LMR often hiding under flat rocks in the swift current. Darters eat mostly small crustaceans and aquatic insect larvae. Sculpins and Madtoms The LMR is home to five species of madtoms as well as the mottled sculpin. Like the darters these guys spend most of their time glued to the bottom of swifter riffles and runs or at least right on the edge of such places. Ferocious predators they are almost like tiny three to five or six inch long shovelheads, eating whatever they can fit in their mouths. More camoflaged than darters they are usually colored to blend in with their surroundings. Chubs The LMR has around seven or eight species of chubs. Chubs mostly have a thich rounded body and can grow fairly large, up to a foot in some species though most are around five or six inches in length. Chubs eat small invertabrates and insects but large ones can even take small crayfish. Chubs grow big enough to be caught on hook and line and are often caught as shovelhead bait. I almost dont want to get into crayfish because I'm going to part ways with 95% of you on this. First off they are very important as smallie food. So important its almost impossible to overstate their importance. That being said heres why I hardly ever imitate them! Even though I'm constantly fishing for smallmouth that are feeding on them. First off, pick a day in June. Then there are really only two sizes of crayfish in the river as far as a smallmouth is concerned. Great big ones left over from previous years and ones hatched this year. The old ones may vary in size but to a smallmouth they are all the same size...too damn big. Every study I've seen says that smallmouth are constantly selecting small crayfish and leaving the big ones alone. Or if they take a big one they circle around it a while or pick it up and blow it out several times till they get it facing tail first. Several studies suggest that the very biggest smallmouth are the most selective for size. Ok so that leaves me that years crayfish. In midsummer that years crayfish reach a size that smallmouth love. In one study in Wisconsin crayfish were 14 percent of food volume in May but a whopping 83 percent from July to September. So after July if you catch a smallie he's probably looking for a craw. So heres my problem. Smallmouth arent selective about minnows in the LMR, they come in all shapes, colors, and sizes so they cant key completely on just one. But young of the year craws are all the same size, the same color, almost exactly. And this size changes constantly. In their first year crayfish molt something like ten or eleven times because they are growing so fast. So every craw looks the same, is the same shade at the same time in that hole and every smallmouth knows it. So I cop out. If a smallmouth is nosing around looking for a craw and a tasty minnow imitation like a three inch grub swims along he's not going to pass it by. Ok so why is the rebel craw such a great lure? Look at these two pictures...
Big craws out of the LMR
Little craw out of the LMR Now lets be honest does a rebel craw look anything like either one of those? Does it act like them? I think a rebel craw is a crankbait that is just the right size for catching alot of fish in the river and it doesn't run too deep like something like a model A bomber does. It wobbles along at a good depth to fish below and above riffles and its a good size so it catches fish. Heck I fish one alot. I just dont really think I'm imitating a crawfish. Its generic fish food I'm imitating. When I'm bouncing a grub in the rocks or hopping a marabou jig along the bottom or fishing a suspending crankbait just off the bottom, thats when I feel like I'm fishing for smallmouth feeding on craws. Smallmouth are opportunists and theres too many minnow species for them to become selective so I'm not going to throw something like a really detailed plastic craw at them because thats the one and only thing in the river they just might be selective about. He might hit my big living rubber jig with a plastic craw trailer but he's going to really look it over and he might be just a bit afraid of it and suck it in and blow it out a couple times first but the same fish is going to confidently swim over and thump my smoke metalflake grub without a second thought. Like I said I'm going against the grain here but I dont try to imitate craws in the LMR when lure fishing. I think alot of the small dark jigs like marabou jigs or little living rubber jigs or even wooleybuggers the bass thinks is something else yummy like a hellgrammite in addition to a craw. The nice thing about fishing is people can look at things completely differently and both still be right some of the time. __________________ __________________

  2. I just started fishing this year about 2 wks ago . Last wk I used red worms and caught several species of fish to include smallies , white bass , sauger , carp and catfish . Two days ago I fished Todds Fork with a black and purple Rooster tail and caught several Smallie 2lb and smaller while wading . Spring is the best fishing ever . I've caught fish on every lure I've ever tossed in . Good luck .
