do catfish and carp eat freshwater clams?

[Paulpro]

Hmm,I do notice empty clam shells aroud the shoar of the lake,but it could be the birds..carp around here love it after a good rain so they could feed on the fresh grass,also love berries such as from the Ficus trees and Mullbery trees.I never thought they would suck down a baby duck,what do you think please check both vids,carp are in a frenzy and suck down baby duck"viewer discretion advised",don't look if you don't like this kind of stuff,this is raw nature at its best.fish food is a random vid I found, I forgot the name of these fish,also a duck gets eaten. "discretion is adviced".
