Happens all the time, but Bass aren't the most common contaminant. Swamp Darters, Fundulus seminolis, F. similis, Gambusia, Bluefin and Swamp Killies, Black Bullheads and Tadpole Madtoms have all found their way in recently, as well as a couple of Bass.OT but that's weird... Did you find out how he got in there? The packer didn't even notice??
