Is a billy club legal? Shooting them while they are in a net seems so unethical, and not very sporting.
Our hands are tied. We must shoot them after they are caught in the net to be legal...
TPWD Website "Lawful Hunting Means and Methods: Shotguns, archery equipment, falconry, dogs, artificial decoys and manual or mouth-operated bird calls are lawful. Hunting is permitted in the open or from a blind or other type of concealment or from floating craft or boat provided that all motion resulting from sail or motor has ceased. Sails must be furled and motor turned off before shooting starts. A "sinkbox" (see definition) is unlawful."
Ergo, once they are caught in the net the only legal means is to shoot them...
