I have done something a bit different during the summer but with waders I think it would work now. I would wade out in the water about knee deep and mound some rocks. Next place a couple tins of cat food with some poked holes around your mound. Leave till it gets dark out, wade over with a flash light in one hand and long tongs in the other. When the light is shone on them they freeze. Place tongs over and gently close. I just float my pot for cooking them right beside me and toss em in. I have done surprisingly well with this method.
