Along with bass, cod, eel, flounder, sole and whiting, seahorses and dolphins are flourishing in the Thames.
But upriver, every time there is a deluge, millions of tonnes of sewage are pumped into the river to prevent drains overflowing.
"Often there is more sewage than water going into the river in some areas.
This is having a big effect on the wildlife higher up the river," said Jon Averns, the Corporation's health director.
The Health Protection Agency is undertaking a [pounds sterling]50,000 yearlong study into whether the Thames is a health risk for recreational users, some of whom have suffered stomach upsets.
"Our advice to Thames river users is to wash their hands after touching the water. And if they ingest any water
they must contact a doctor immediately," said Mr Averns.
"There is the potential for the Thames to become a major public health issue and with the Olympics coming up we need to make sure it is a clean river particularly as a lot of the rowers will use it for training purposes. …
