Like many (most?) of China's lakes and rivers, Taihu Lake is now severely polluted from decades of raw sewage inflow, industrial waste dumping, and agricultural run-off. Massive algal blooms are common. China's solution is to stock Taihu with "pollution-fighting fish" - namely silver and green carp. Both are vegetarians and eat massive amounts of vegetation, including both benthic and pelagic algae. China expects them to clean up Taihu Lake.
The irony is that these fish also excrete quite a lot, as do all vegetarians. And both prefer vascular aquatic vegetation. And both are rooters, destroying nesting habitat by both mating and feeding activities. And both are extremely prolific - silver carp in particular often quickly become the most numerous fish, crowding out native species by sheer biomass. By introducing such fish, China has almost guaranteed to complete the destruction of this huge and once scenic and productive lake.
Damned shame. Cleaning up a lake requires removing nitrogen and phosphates, not adding millions of nitrogen generators.
