Eating a tank raised fish will most likely be much healtier than eating anything you catch in your local waterways. Trash, sewage, farm runoff...yeah sounds tasty and good for you. Not to mention all the areas that specifically say not to eat any catch because of high mercury levels. My wife was a farm girl too, and they always had pet livestock that they personally cared for and raised until it was time for slaughter. Besides at least you know they were raised in healthy conditions and were treated humainly, which is much more than you can say for anything you buy at the store.
