Week in Wildlife: Chinese officials release algae-eating fish into Taihu Lake in Suzhou

The North Americans may be terrified of them, but in China the so-called 'Terminator' fish, the Asian carp, is in great demand. Here, a Chinese official releases the fish into Taihu Lake in Suzhou, which has been severely polluted by sewage, as well as industrial and agricultural waste, triggering a virtual plague of blue-green algae – a tasty treat for the voracious carp. Authorities say they will release 20m of the algae-eating fish into one of China's most scenic but contaminated lakes as part of a cleanup programme
