Just an observation from Super Bowl Sunday. I went to the Stones River Sunday morning and froze my fingers. Got skunked and only fished for an hour or so, but I did manage to net a couple dozen small Shad for the pond. Here is what I observed. When the Shad are released, the healthy ones scatter, only to regroup in small pelagic schools. The weaker Shad swim weakly with no intended direction, often on their backs. The extremely weak Shad swim weakly to the pond bottom and unintentionally bury themselves into the bottom vegetation. The largemouth become super aggressive when the shad are discovered and don't mind at all coming right up to the bank where I am standing to feed. The clear water allows me to observe everything. What I have always wondered, until now, is how bass remove and consume prey that inhabit the pond bottom. Here is how it goes. The LM will notice movement, move in for inspection, hover over movement, creep close, then inhale movement, vegetation, leaf debris, sticks, everything! The LM will then slowly back off, and gradually work the debris away and separate debris from prey. This takes several seconds to complete. I do not know how prey is retained while debris is expelled but I witnessed it several times Sunday. When satisfied, the LM will slowly search the targeted area then move on.
Don't know if this info may help those that like to Texas Rig, or Carolina Rig, but maybe somehow it will.
