Die in hundreds of sea lions Chile
SANTIAGO DE CHILE .- Hundreds of sea lions, and young adults, were found dead and dying in a wolf-of Iquique in the north. While some blame the lack of food, environmentalists point to a molybdenum plant, a thermoelectric or some mines in the area.
Iquique Authorities attributed the deaths to lack of food and reported that some samples were sent to Santiago to investigate the causes of deaths.
A statement from the National Fisheries Service, Sernapesca, attributed the deaths to lack of food in Pacific waters caused by the El Niño Current. He added that mothers are out to sea in search of food, leaving their pups abandoned on the rocks.
The regional director Sernapesca, Maria Soledad Tapia, director of Marine Rescue Center of the city of Iquique, Pablo Villegas, contend that the problem is caused by lack of food in northern waters.
"Usually lions are smaller those who die, due to the absence of the mother who moved long distances to find food," said Tapia.
