i had the same thing this last weekend fish were only truely active for about 1 hour and it seemed to just shut off. so i decided to start crib hopping with my new camera. i would take 20 -30 min setting up everything perfectly then fish for about 5-10 min jigging very aggresivly at the smaller fish and until i entice the bigger ones than start to jig for that fish. once i would catch the 4-6 good fish in that crib i would move on. i swear on over 90% of the fish i cought you didnt see the rod or spring bobber move. sight fishing for gills and crapies was a blast when the bite was that light. ended up with about 20 gills over 8 inches
