They used to use trot lines and sein nets in saltwater in the 80’s. I have no idea about freshwater but they were outlawed for commercial purposes a long time ago because of the death of the bycatch.
When I was a kid we had to empty the shrimp boat nets every 15 minutes because they were full...so many shrimp! I have no idea where they all went but the commercial fisherman “killed all the native grasses” so it was back to full time auto repair again.
You could take a light and shine behind the boat and the Cobia would follow the boat the entire night. Sadly, those times are long gone
