I've had better luck during the day because thats normally when I go. Have tried at night a few times ,but havent had any real luck. You can shoot alot of silver carp ,just about all day long ,till your tired of shooting.The only draw back to this is they are not very big. Average size 3 to 6 lbs with a few pushing 8 to 12 lbs??? I'm going to try to hit wolf island just outside East Prairie this weekend. The water here is usualy never clear but the silver carp action you can't bet. And so far (knock on wood) the fish are fare size as well. Average 8-10lbs with some pushing????
