Heres a story a lot of people may not know. Years ago (can't remember the year) a guy caught a wiper on Pueblo. Rather than quit fishing and taking it in to be weighed (it was huge) the guy put it in his livewell and continued fishing. At the end of the day he took it in and had it weighed and it came up just ounces short of a world record. The fish had regurgitated a lot of shad into the livewell and its considered very likely that the fish would have been a world record if he had taken it in right away.
Anyway, that's the story I've heard several times. Could be urban legend-maybe somebody who knows can post.
