I do not have any pics of this, but it could be the salted baits. My buddies house has a good little dock with lilly pads and there are always quite a few largemouth spawning there every spring. He fishes them pretty heavy with my stick baits, and there are probably 4 or 5 discarded baits under his dock that are ballooned up like that. The fluke I found in my boat was heavily salted too, so I guess it could be the salt/plastic mix. I noticed a real Senko that I found the other day that had been in the water was not expanded, just bleeched out really bad. I am not really worried about the fish eating these, due to the size of the baits, but I really don't want to see a bunch of junk in the water if you know what I mean. I might have to do a little experiment with a Senko and one of my baits and then take some pics to show you guys. I am not really sure how long they take to get that big, but I guess we will see.
