By Martin Hickman, Consumer Affairs Correspondent Japan’s sprawling Mitsubishi conglomerate has cornered a 40 per cent share of the world market in bluefin tuna, one of the world’s most endangered fish. A corporation within the £170bn Mitsubishi empire is importing thousands of tonnes of the fish from Europe into Tokyo’s premium fish markets, despite stocks plummeting towards extinction in the Mediterranean. Bluefin tuna frozen at -60C now could be sold in several years’ time for astronomical sums if Atlantic bluefin becomes commercially extinct as forecast, a result of the near free-for-all enjoyed by the tuna fleet. In the forthcoming documentary film The End of the Line, Roberto Mielgo, a former bluefin fisherman who travels the world monitoring catches, claims that Mitsubishi buys and sells 60 per cent of the threatened fish and that it has expanded its freezer capacity to hold extra bluefin. … Fish stocks across the world are in retreat because of over-fishing.
