How safe really is it to eat your home grown fish? I know lots of you do it, but--My understanding is that if you buy farmed fish there could be lots of problems, because temperatures have to be just right, bacteria, and a whole host of problems could come up. Thing is, growing your own, you do know where it came from, but do you know for certain how healthy the fish are, or free from bacteria, or other problems? How do you know it? How can you be certain there are no parasites? I eat Alaskan cold-water salmon, which I think is about as safe as it gets. The ocean being a larger filter than your home system. I would love to eat aquaponic fish but I have big questions about it. Can anyone set me straight please?
