found my 3rd largemouth bass this morning. cant figure out whats killing them,all are nice size 13" range. finding on shore stripped down to bones.

My thoughts are that dead fish found stripped to the bones likely died of reasons other than a predator and then were scavenged by turtles, crawdads, other fish and the like.

I have heard of otters killing more than they need. Look for signs of them because they can be bad to have.

I'm in S.Mich just west of ann arbor. Haven't seen any snappers yet,we do have mink and seen an osprey last week.
