this gentleman claims they were offloading in cameron, and not just a few flounder, like hundreds. And also that the nets were modified, i'm not sure why he would lie?
edit
here is a possible loophole
Flounder, Southern
: Ten fish for each licensed fisherman for each consecutive day on the water EXCEPT any commercial shrimping vessels may retain and any commercial fisherman may sell all Southern flounder caught as bycatch on any shrimping trip.
