Largemouth bass are among the most popular sportfish to catch in Ohio.  However, their smaller, prettier stream dwelling cousins can be equally as much fun to target and offer new and unique fishing opportunities for anglers.  Explosive strikes, powerful aerial leaps, and beautiful habitat are just a few reasons you should target smallmouth bass this summer.  This article aims to highlight the attributes that make this species so fun to catch, their ecological significance, and how to successfully target them.

One of the most notable attributes of smallmouth bass is the waterways they inhabit.  The sensitive fish requires clear, cold, and clean water in order to thrive.  Here in Warren County, that means smallmouth are primarily found in our numerous rivers and streams like the Little Miami River, Caesar Creek, and Todd Fork.  While beautiful on their own, these waterways attract numerous other species of plants and animals that can also be seen.  Like largemouth, smallmouth bass have earned a reputation as a powerful fighter, oftentimes feeling significantly larger than they are on the end of a line.  From birth, harsh, rocky bodies of water with strong currents condition the smallmouth to develop strong muscles for speed and agility in the water.  Pound for pound, this makes them one of the strongest fighting freshwater fish of any species.  Smallmouth bass have been known to grow up to 27 inches and over 12 pounds.  However, here in Warren County, most mature fish are within the 2-5 pound range.  Additionally, smallmouth bass have a powerful predator instinct that makes them fairly easy to fool into biting a hook.

Smallmouth bass offer numerous ecosystem services that make them invaluable to our local waterways.  Two of the biggest are acting as an indicator species for water quality and keeping populations of baitfish balanced.  Smallmouth bass rely heavily on their eyesight to hunt for prey.  Without clear water, the species cannot effectively hunt and numbers dwindle.  The species also requires cool and well oxygenated water to thrive.  A lacking smallmouth population in our local rivers can be a strong indicator of bigger environmental problems like pollution or drought.  As apex predators in their habitats, smallmouth bass are also a key influence on minnow, crustacean, and juvenile fish populations.  Their aggressive feeding behavior and diverse diet help to ensure populations remain at stable levels. 
​
As mentioned earlier, smallmouth have a diverse diet and are fairly easy to coerce into striking.  Because of this, they’re not difficult to catch.  Look for them in current breaks that allow them to keep close watch on nearby current for prey being washed downstream while also expending as little energy as possible.  Good places to focus on are eddies, sunken logs, and deep pools.  Smallmouth can be caught using numerous different methods, but spin fishing and fly fishing are the most common.  A 6-7ft medium to medium heavy spinning rod and a 9ft 6-8 weight fast action fly rod are best suited.  Conventional freshwater baits designed for trout and other kinds of bass all work well with smallmouth.  Best of luck!
