So who's ever actually eaten freshwater fish then? The nearest I've ever come was when, in two rash moments of open-mindedness, I decided to try Vietnamese river Cobbler and Indian Kingfish(whatever that may be). Never again, on either count! Dreadful tasting they were, particularly the Kingfish, which for all the world looked like a lovely Swordfish or Marlin steak, but tasted hideous and stunk like a week old dead Bream.
And now, after watching Dispatches the other night, I shall be much more cautious about eating fish, and any seafood for that matter, farmed/produced in the far east. Some of the hygien, or lack of, as the case may be, was truely gobsmaking. Dogs walking round fish markets, eating scraps; flies everywhere; fish being frosted, and then defrosted repeatedly; injecting prawns with bulking agents.... the list goes on.
I can't imagine how disgusting some of our domestic freshwater species would taste, but after watching the above, and if I absolutely had to, then I'd go with the Tench Mornay.
