I'm attempting to attach 2 pics of what I believe to be the same fish from August to December. Attached Images Last edited by shooterlurespond; 02/29/24 07:57 PM.

I always attributed it to winter water temperatures lower than 39F. This may not be the reason since these affected LMB are in NC. Was the pond bottom aerated 24/7 during winter?

Windy conditions keeps freezing air temperatures and chilled water from freezing and thus this 'over' cooled water mixes deeper into the pond than the surface layer, thus this chills or 'super cools' the overall pond water lower than 39F. If that did not happen then the LMB are being stressed by some other feature during this past winter to cause the abnormal red tissues in the mouth. Last edited by Bill Cody; 03/02/24 08:47 PM.
