I have a freezer full of them lol. The best bait for them is earthworms. I have also done pretty well on the big ones with small pieces of cut bait. If you can find them on open flats when they are on dense nests, I have caught them on big spoons on almost every cast.
I donโt think you will have luck getting TPWD to provide any funds or benefits to fish for them. They are baby producing machines and are basically only limited by cold water in Texas. JJ4MEL is correct. I have seen lakes where anglers with cast nets took ice chest after ice chest of them out of the lake everyday without making a dent.
They are great to eat and fight like crazy. This is 120 quart cooler. Good luck fishing for them.
