JHAP absent supp feeding, as a general rule pond type fish that grow fast (BG and LMB in the south with a long growing season vs north with short growing season for example) don't live as long. There are of course plenty of exceptions like lack of stressors. One study on trophy LMB noted the high % of them with both faster growth and normal life span thus they had both when most LMB did not). One of the advantages of Fla LMB and why they get bigger (a least the females) was longer life span than Northern LMB in the same water.

I have not seen any data on the effect of supp feeding on life span.
