They're not accidents, they see better than you or I do in sunlight.
There is no limitations on gigging, not trout, not equipment, none and its not the sport that's protected, but the harvest.
They have literally "overgigged" and in order to feed the crowd that always follows the traditional, they take 8" Hog Molly's and any smallmouth they think they can get away with. They've pretty well wiped out the big Redhorses.
I don't think the problem lies in the sport, but in the equipment and the "new" members it draws. Its about as close to shooting fish in a barrel as one can get, with metal halide lighting, gas motors, light weight gigs, and cell phones, there's little resemblance to wooden shaft gigs, paddles and pine bolls. The new gigger can go deeper and spear a fish frozen in a blinding light, and then use the phone to insure its safe to bring illegal fish to the pot.
I suspect that if a real effort was made to limit gigging to something that resembled the old sport it would be successful if done right. A picture is worth a thousand words and in this case could probably acquire thousands of allies.
