This is only an observation and not directed to any one involved in this topic.
As a kid, in the 50's and the 60's, I learned to fly fish in the most of the creeks and rivers in camden, miller, and laclede county. In all of those creeks and rivers I caught smallmouth, largemouth, and red eyed kentuckys. In all of the creeks, the kentuckys were the most common. To me they were a creek bass, and the largemouth was more of a rarity. That was 50 years ago and they were well established back then. Bagnell dam and tunnel dam had been in place for years, which means that kentuckys had to be in the system prior to the dam. Now if you fish a tributary that empties into a tributary that eventually empties into a lake. Most of those dams have been in place since at least the fifties. I don't see kentuckys being a "new" problem. They have been in the rivers and streams that I fished for 50 plus years. By making this next statement, I will expect to see my head on the chopping block.
I personally think, that continual catch and release, leads to overpopulation and stunted growth rates. You see it most often in ponds, but I believe it has the same effect in rivers and especially smaller streams. Pretty soon the fish will eat up most of the crawdads, frogs, and other aquatic food that the creek can maintain.
Just an observation, thanks for listening.
