Starting out a debate or discussion with, "I seriously doubt that", is meant to belittle or sway him under pressure, to agree with your point!
Do you actually think that things are exactly the same in your area of Ky or His in Texas, or mine in OH...my almost 2500 acre lake is totally different than anything else in Ohio, let alone somewhere else.
So someone posts something that may be credible, but then you disagree with it right away....it was not debated or discussed...And why would you provide him with an "Out" if you weren't trying to fold him back into your line of thinking!
"Ye of Little Faith"...People can Blindly Believe in Religion, but are Supremely Skeptical of anything that they haven't seen, witnessed, or that goes against their thought process! Funny Huh???
If he doesn't fish like you is he wrong? If he catches more fish than you, are you going to change to his style because it's better??
First of all the research in FL was solid and still viable...the SW district of the ODNR is also looking into this because we are getting out of season fish that go against the known norm.
Shad are also being questioned....right now guys who are ice fishing the Marina docks are catching Crappie that should be in your home aquarium....guys have been netting and posting pics of 2 inch shad in December. Just like the FL research, the fish would have to be hatched in the Fall.
Our lake is very fertile over populated by baitfish, fish grow fast under these conditions for the North.
We had no Spring last year, and very little Summer....the temps did not reach and consistently stay in spawning temps until late Summer....TEMPERATURES NEVER REACHED A POINT TO TRIGGER THE FEMALE HORMONE TO ABORT THE EGGS AND ABSORB THEM! IT TAKES HIGH TEMPS TO TRIGGER THAT HORMONE! SO, since that didn't happen, and water temps were perfect in the fall with sustained 65 degree water in September and October....why is this not plausible??? Our water temp was 48 degrees all last week...we just added 3.5 inches of warm rain on top of that...perfect way to start a discussion of 2 inch shad and 3 inch Crappie IN LATE DECEMBER!
Evolution can also be Generational...Scientists are studying species specific adaptations, that they think are actually genetic evolutionary improvements to groups of the same species in different areas or environments.
They are also learning that Species Evolution is happening at a faster pace now then ever before....due to Man made influences.
But religion has no place for Evolution, so Adaptation is a word that Religions can use in place of Evolution!
So Yes, the fish are adapting at a faster pace than normal, due to the increased influence of Man, or Man Made impacts to their environment!


Good Fishing!
