Rio de Janeiro, March 14 (IANS/EFE) Thousands of dead fish washed up on the shores of the Rodrigo de Freitas Lagoon, a Rio de Janeiro tourist attraction, Brazilian authorities said.

A large amount of organic matter that entered the lagoon as a result of two recent large storms consumed oxygen and brought it down to critically low levels, Carlos Alberto Muniz, the municipal environment secretary, told Efe.

This situation caused a massive die-off of shad, whose number had risen since mid-February after the fish had entered the lagoon to spawn, Muniz said.

The government now is working to remove the rotting fish and the strong odour and had collected 12 tonnes of dead shad as of Wednesday, the official said.
