BUENOS AIRES, Aug. 15 (Xinhua) -- As many as 40,000 cattle have been attacked by carnivorous fish the piranha in the northern Argentine province of Formosa, the region's producers association Aprobae said in a statement published by Wednesday's domestic press.
The focus of the attack is the 400,000-hectare Banado La Estrella area, 1,500 km north of Buenos Aries, home to 300,000 cattle. Thousands of the deadly fish have been trapped in the area by dams that have formed. They attack animals who come to drink the water.
Pablo Herrera, coordinator of the Gran Chaco Forest Life Foundation, said the area had a great deal of biodiversity.
Rafael Silva, head of the Formosa Province Water Coordinating Unit, said that there had always been piranhas in the area.
"Public works are trying to better distribute the water, so that drought areas can benefit. Some 70,000 people live in such areas, "said water authorities.
The Aprobae statement said that the organization would take "other measures" to make sure its voice is heard.
