This fish, now on the brink of extinction, is now slated to be sold in Itamae Sushi in Hong Kong. WWF has organized a media campaign to denounce Itamae and Itacho Sushi, including posting an obituary in South China Morning Post and distributing pamphlets urging a boycott of the Itamae Sushi chain, which has over 20 outlets around Hong Kong. The chain's front man, Ricky Cheng, is known to buy high priced Blue Fin Tuna for his restaurants in the past.
