Where do sardines gather in huge shoals?
Quick Answer
Sardines gather in huge shoals in coastal waters, especially where cold, nutrient-rich currents bring food to the surface. One famous region is off South Africa during the annual sardine run.
The Full Story
Sardines form immense shoals in productive coastal waters around the world, but one of the most famous events is the sardine run off South Africa’s east coast. Each year, large numbers of sardines move northward along the KwaZulu-Natal coastline, attracting dolphins, sharks, seabirds, and other predators. Similar schooling behavior occurs in other nutrient-rich marine regions driven by currents and seasonal temperature changes. Shoaling helps sardines reduce predation risk and improve feeding efficiency.
