Here’s one for the hall of fame…

Chinese authorities are using algae-munching fish to clean up one of the country’s most polluted lakes — and after their diet of toxins they will be sold on to consumers, state media said Thursday. More than 50,000 silver carp fry have been introduced into Chaohu lake and another 1.55 million will be added in the next 20 days… Each carp is expected to have gobbled between 40 and 50 kilogrammes (88 to 100 pounds) of blue algae when it reaches its adult weight, with each chomp of the sludge helping to clean up the toxic lake, the report added. Once the carp have matured, fishermen will be able to catch them and sell them in markets, at a price 15 times their original cost, giving a boost to the local fishing industry, according to Xinhua.
