To Fish or Not To Fish

Similar to my organic produce dilemma, I am confused about how much and which fish I should or shouldn't be eating and/or feeding my children. This question has become particularly astute as I decided during my weight loss journey as I have tried to fundamentally change what I eat and what I feed my children.

Marc does not eat fish. Well, he sort eats fish. He'll eat sushi. And he'll have me taste fish to see if it is fishy and if I say it isn't he will try it. I'm not sure how I decide if fish is fishy but it seems to work.

I made a decision a few months ago to feed my family fish at least once a week and harking back to my Catholic upbringing this has somehow morphed into Friday's as being fish night. It isn't the best choice because the children both have fish and chips at school on Friday lunchtime but that's my approach for now and I'm sticking with it. They don't seem to mind that they get fish twice a day.

But then I started worrying about the how much fish is too much mercury. And what fish shouldn't be on our table at all due to environmental factors. And then I found this website with an exhaustive list of the fish that are ok, so so ok and not ok under any circumstances.

There is some trouble with this list.

1. It appears to be North America focused. Imported fish seems bad. Does that include imported to the USA or just imported to anywhere? What if it is imported from the UK? Does that mean it's not imported to me and therefore is ok?
2. The list is very specific about where and how the fish is caught. That's not always on the package labelling here in the UK, especially since I do most of my shopping online at 1 in the morning. I can't imagine trying to figure out if it is line caught or wild Alaskan.
3. The list is long. I'm not sure how workable this list is during my weekly shopping trips.

The good news for me is mackerel is a good fish. I love mackerel. My children love mackerel. My husband hates mackerel. Kippers are not listed. Does that mean this is ok? Or is there another name for kippers? Tuna seems to be ok and seriously not ok. Ug, I love tuna. Does it count if I put it into my world famous tuna noodle casserole?

I think I'm more confused than I was when I started this quest.
