Concerning fish that migrate, move around, or not move around.
As for migrating around, it was intimated or else, just bold-faced thrown out like a shovel full of nightsoil, that migrating, or bar-hopping fish would spread their genes around like humans did before birth control methods prevented blank shots in the dark at places like the parking lot and surrounding bushes at Posey’s. Although, I have not heard of any similar research on our sport fish, Pacific salmon are hatched in mountain streams and during the time it takes for them to grow to some size (largely eating the shredded flesh of their parents, that die after spawning, and get run through the blender of countless rapids) these small salmon take a biological imprint of the, “smellâ€

In the absence of any other comments, I assume that the trout never leave the bays and rivers.
In which case, they will exhibit all the traits of impoundment fish.
It does make it hard to explain how some years can be classed as "good" years (with larger fish) and others not so good.
Population variation with few, or more fish, is understandable, but not size variations.
Anyway, I think the areas with "stunted" fish, are probably those where the anglers are using fishbites and non Shimano reels.
Fish have standards.

The size variability of trout in this area seems to have a rather large variety of possible causal explanations, even including the use, or not, of certain attractants and brands of tackle. Like what was offered before, as to the small fish size vs. advanced level of tackle technology, in reference to the Apalachicola Bay region, this would likely relate to a difference in the attitude of the fishermen – enlightened one’s that would easily abandon unproductive methods of tackle and techniques would quickly become more successful and catch-up the larger fish and then would start a steady harvest of fish as they began to reach any good size, resulting in mostly small fish being caught. The seemingly important question is, “When small fish are being caught in a particular area, is this the result of no large fish being present, or that the fishermen don’t have the terminal tackle or techniques to catch big fish that actually may be present?â€
A most enjoyable read. Science has very rigorous standards of evidence. Knowing how rigorous these standards really are is difficult if you have not really engaged in science as a discipline. The paper I cited demonstrated that there was evidence (genetic) of estuary specific growth characteristics. This means that speckled trout grow at different rates in different areas. Emphasize genetics and rates. Like reading tree rings the trout were shown to grow faster in some areas. This was done by measuring the “ringsâ€
