The two may be linked when a summer draw down results in much of the cover in old lakes being on the bank and the little bass, as well as their food sources, are easier forage for everything else that is larger. In a lake where there have been die-offs such as Rayburn and Fork, Mr. Inman suggested there may be some reasonable logic to infuse numbers of new Florida stockers. The reasoning is that because of the die-off an influx of pure Floridas may act the same as new stockings do within a new lake. They could rapidly populate since the competition is less because of voids previously filled by the lost fish. The other issue as far as efficiency for catching bedding bass is based what presentation you are using.
Artificial lures are much harder to use in enticing a strike than live bait.
In fact I have watched folks fish right through a nest that they didn't realize was there and seen the bass take the bait, but usually the fisherman removed it via his retrieve without inducing or feeling a strike. An inherent protection for bedding fish also occurs in lakes where there is turbid or off-colored water. If you don't see the bass on the nest, then the chances are good that your random cast will miss the nest or you will work the artificial bait out of the nest without ever causing a pickup. It is rare that even those specializing in sight fishing don't have to make numerous presentations to hook a bedding fish. The fish that you normally catch around the nest are males, which are acting both as sentinels as well as at certain times willing to eat an easy meal.
