Mulberries are falling like raindrops in a lot of places right now. Do you know of a mulberry tree along the shore of a carp pond or river? If so, fish that spot. Carp just love mulberries and they will go crazy feeding on them. They will take them off the surface as well as off the bottom.
The strategy for the carp fisherman is to freeline these berries. Simply impale them on a #6 or #8 hook (see photo at left). You may have to squeeze them a bit to get the air out if you want them to sink. Simply cast the offering (no sinker) and let it sink. Any carp in the area usually go right after your offering. I've been catching carp (see photo at right of fish caught this morning) the last two days on mulberries. They should continue dropping for the next couple of weeks. In the past I have caught several carp over 20 lbs. using mulberries.
