You know very well that those small bubbles are not formed by the fish stirring the mud at the bottom of the water, but by the silver carp.

Including other fish, carp and grass carp, spit bubbles directly from their mouths. Maybe carp have the habit of digging mud, but the mud has no direct sunlight and no bubbles.

Silver carp generally don't spit bubbles, and only when they swallow the bait particles in the nest will tiny and uniform bubbles appear, one after another.

As for fishing bottom or floating, it depends on the actual fish situation, which fish layer has a mouth and which one to catch.
