"Oh, the local state fish-and-game people built ’em years ago. The floods, and the poisonings and such, wiped out the local game fish. The Teche was getting bad algae blooms, almost as bad as that giant Dead Spot in the Gulf. So, they cobbled together these vacuum-cleaner fish. Big old channel catfish with tilapia genes. Them lunkers get big, bro. Damn big. I mean to say, four hundred pounds with eyes like baseballs. See, lunkers are sterile. Lunkers do nothin’ but eat and grow. While the lab boys were messing with their DNA, they kinda goosed the growth hormones. Now some of those babies are fifteen years old."
