Here is one of the fish that I raised in 2018. Last August I caught one around 13". Last night we caught 3 rather quickly between 15.5" and 16.5" and very thick. We had been struggling to catch them but found a technique that worked last night. We put a fathead minnow 2 ft. below a float. They hit within seconds each time it hit the water.
