Off California, fish populations may also be reduced. Marine mammals, such as seals and sea lions, that feed on fish may be affected.

How does El Niño negatively impact the fishing industry in South America?

During an El Nino year, however, the winds, which blow along the surface of the tropical Pacific Ocean, ease. Why this happens is unclear, but it can have dramatic effects. The warm water sloshes back towards South America, which hides the nutrient-rich cold waters and ensures fish are in short supply.

How does an El Niño affect the fishing industry off Peru?
