• upwelling

• increase in surface nutrients

• colder water at the coast

Why do the fisherman of Peru and South America not welcome a strong El Nino?

• El Nino poisons the fish

• El Nino causes strong winds and currents which move fish westward

• El Nino bring cold water to the surface which kills the base of the food chain

• El Nino shuts off upwelling and nutrients needed for the marine food chain do not rise to the surface
