Bass have to become conditioned to baits, otherwise how would the bait companies sell that new and exciting bait.

If a bass had any type of intelligence none of us here would ever catch a single one. But they are not capable of a single thought and that is why they can be caught not just once but numerous times throughout their life.

Keith Jones, Director of fish research at Berkley does his research on bass in an aquarium or tank and the results aren't worth the paper it's written on. His theories have been shot so full of holes it's become almost comical, he's paid to sell a product period. In one of he's reports stated bass are turned off by anise oil and will not bite a single lure that contains anise. Yet every year hundreds of thousands of bass fall pray to lures laced with anise oil so I guess the bass never read Mr. Jones's reports.

So this mostly will apply to hard baits. Since most plastics and swim baitshave naturel movement rite? The bass will remember the movement of a crank, top water, spinning and buzz. So if I used one spinner that was productive then stopped I should change color or add a trailer?

It applies to all baits, but probably less so to soft plastics. But, the main part, in terms of catching fish, is that all the elements of angling enter in.

The problem is angling in general. You just have to fish "better" than if the pond hadn't been fished before. Meaning:

#1 Be stealthy

#2 Learn to present each lure very well. Learn to adjust (vary) your retrieves to trigger strikes.

#3 Pay attention to what others are using and either use them better or, if it doesn't pan out, try something very different. BUT before you write off any lure (often people choose them for a good reason) know the conditions and situations where that lure shines and it'll likely still work for you (see #2).

#4 Changing lures, after catching a few in a particular spot, is a good tactic.

What was the question again? I forgot.  

It's in the subject title.  

Great question.

Sharkbite, did you feel your questions were answered?
