I was watching a number of carp early this morning (lake was as still as I've ever seen it)rolling on the surface and approximately 5 to 10 seconds later a big patch of frothy bubbles emerging in the immediate area.
Question is, are these fish inhaling air to expel something which they do on the way down as they didn't appear to be taking anything off the surface and certainly weren't crashing out as if cleaning muck out of their rakers. My mate reckoned they could be building up steam before plunging into silt pockets to get at bloodworm etc but that sounds like rubbish to me.
Any ideas?
