Sadly true about the depleting fish, Darin, something needs to be done. So many livelihoods are connected to the fishing industry, the mention of a moratorium brings the thought of economic suffering. Politicians would be timid to bring it up. People here won't even stop their whaling practices done for "research purposes", and pretty much against worldwide opposition amongst the international whaling commission members. Nor will many stop eating it. Ongoing research on how whale flesh fits into a can, I believe. I haven't heard anything about clandestine fish being substituted at the sushi bar, you may be right, but I would have thought that it would make the news. I know that at restaurants if you order a certain fish, they will tell you that it isn't available, and may suggest one similar. Food news is a big topic here, sometimes there are scandals about unscrupulous things being done at high class restaurants. Recently there was one about prawns. A lot of prawns are imported from Thailand, people were caught selling them as the rarer and more expensive domestic goods, and a big stink came out of it. The maitre d' had to click his heels twice when good customers arrived..
