Have you ever noticed that when a pro angler is being filmed, while unhooking his lure, they toss it over the side after it's extracted from the Bass' mouth?

Is this so viewers will not be able to get a good peek at what bait they're using?

I could not think of any other possible reason for this little Backhanded toss.

I usually throw mine over the side to keep exposed hooks out of the boat.  Lots going on after you've caught one whether in a tournament or not including putting them on the bump board, culling, stowing the net, etc.. 

 

The last thing I want to worry about is getting hooked.  I'll worry about my bait after I'm ready to start fishing again.

I agree with both of what you guys have said, and I'd guess its a combination of those things.

 

For instance, if a angler is using a lure from a company that doesn't sponsor them, or if it's a pattern or color they think is key for that body of water, they wouldn't want it seen.

 

Lund also makes a good point with hooks.  Everyone that fishes for any length of time gets hooked, keeping the hooks out of the boat helps.

SOP!

Standard Operating Procedure!

I've never noticed, but it actually seems like a good idea. I know that with all that goes on dealing with the fish I've caught, I have frequently looked down and saw my bait/hook wrapped in something, or stuck in the carpet, or I've stepped on it, or whatever. I'm too focused on other things. You definitely don't have time to put it in the hook-keeper before you take care of the fish. Of course, if conditions are moving the boat around, and I'm fishing in a bunch of timber or around something the hook can snag, I'd rather it be inside the perimeter of the boat.

Trebles in your boat carpet can be a nightmare too. Obviously not an issue with a single hook (worm hook) but still, best to keep it out of the way. 

I've seen guys go so far as turn their backs to the camera when they unhook a bass so their bait isn't seen.  I think it's mostly to keep the hooks off the deck though.

I guess I do that to, but my fear has always been something would come and pick that bait of especially a worm or jig which the wind and current will give action too and then there goes my rod
