Went out to a local waterway between two lakes last night. This waterway has a slight current and white sand bottoms, so fish are very easy to spot. But last night I saw something I haven't seen before there. Within a 100ft section I saw two pods of 15-20 carp all feeding on the surface. Imagine like 10 at a time with there mouths completely out of the water. It was weird to watch. I'm wondering what people might think that they were feeding on. I was fishing panfish earlier so I just had a foam spider on, and not suprisingly they weren't interested in that. I know they eat seeds from trees at certain times of the year, but I don't know if that is what they were eating. Any thoughts or ideas would be very helpful. Thanks
