It is beneficial to a lake to remove sand bass. Fisherman, keep all sand bass you want, they repopulate well and don't have a long life span. Besides, they are the better tasting fish to eat. Please put the larger hybrids, catfish and bass back to grow even bigger!!!
One other point that I want to make is that the older a fish gets, the more bad toxins that are in the water that are absorbed into the meat of the fish, with the potential to make your health worse in time.
