Minnows work great for largemouth bass.  Anglers catch bass from 7 inches up to over 7 pounds on minnows.  Depending on whether you are fishing for action or for trophy bass, the size of the minnow you will be using can vary greatly.

Smaller Minnows
(2.5 – 3.5″)

When using smaller minnows, you will usually catch smaller largemouth bass.  Expect to have more action with bass in the 7 to 12″ range with an occasional bigger bass mixed in.  Anglers do usually report many quality catches in the spring with smaller minnows, but as the season progresses, these smaller minnows will usually catch smaller bass.

Fathead minnows and Emerald Shiners are probably 2 of the most popular smaller-sized minnows that you will buy in bait shops.

Medium-Sized Minnows

Some of the bigger bait fish that anglers use for bass are chubs, golden shiners and suckers.  Using minnows in this size range will usually get you plenty of action with lots of better-sized bass and some very big bass mixed in too.  Largemouth bass from 12″ to 5 pounds will gladly eat minnows in this size range.

Big Minnows
(6″ and up)

If you want to go even bigger, you can upsize with the chubs, suckers and shiners.  Down south, you may be using baits as big as 12″ long as you fish for largemouth bass up to and above 10 pounds.  Up north, you may go bigger with a huge chub or sucker in that 7 to 9 inch range.  You may not get many bites when going to these sizes, but when you do get a bite, there is a very good chance that it will be a big bass.
