My experience with Black Carp fishing on lures.
Sinking lures length below 50mm and weight 3-5g. If you are using soft bait, please try minnow shape with the length below 2".
A 2-6 lb ultralight rod and a 500-1000 model spinning reel.
Sinking lures or softbait present in slow action and make sure they move near to the bottom.
Carolina rig is recommended for softbait.
Other species like Tilapia , Cichlids, Catfish will get hooked too.
