Which disruptive outcome occurs during El Niño events?

💡 Explanation

Declining fisheries occur during El Niño because the suppression of upwelling brings fewer nutrients vital fish population, due to reduced wind-driven currents from east to west; rather than increased productivity, therefore, the opposite situation arises.
