People saying that bass are “mushy” or “full of worms” have either never tried them themselves, or there can be large discrepancies based on water temperature/quality/etc.
When I was younger, we annually rented a place on a crystal clear central MN lake, and we always ate bass (along with pike and sunfish). I never experienced mushiness or worms in the meat. These were 14″ – 16″ bass. I’ll still keep a few in the early season. They taste a lot like sunfish. They’re good.
Now, I’m not a meat fisherman. I probably keep fish a couple times a year, but I do have a nearly 4-year old, and like has already been mentioned, I believe that eating some of what we catch is important because 1) it helps to instill that food does not come from the grocery store, and 2) teaching selective harvest is important in teaching natural resource conservation. His sense of pride in helping to put food on the table makes me smile almost as big as he does.
In the end, it’s a personal decision.
