Sardine Run - The Greatest Shoal On Earth

By Dean James


Year on year generally in winter time of June and July in South Africa, one of natures great occasions comes about. Countless small sardines leave their breeding waters of the Agulhas Bank found in the southern waters of South Africa where the cool Atlantic Ocean and warm Indian Ocean meet. It is the matching of these 2 oceans which make the waters perfect breeding areas since they are loaded in nutrient elements.

The precise reasons explaining why the sardine migrate far from such nutrient rich waters are definitely not well-known nonetheless they flourish in water temperatures of close to 20 Celsius. Because winter seas of the Eastern Cape and KwaZulu Natal cool, it is regarded the sardines use their enlarging area and venture north up the South Africa shoreline.

Measuring up to 9 inches long, these little sardines journey in giant shoals clearly seen from the top of the ocean. Regularly the shoals can be a few km's long and up to a kilometre wide therefore apropos numbers, they simply compare with Africa's other well-known migration of the wildebeest as they travel north from the Serengeti in to the Masai Mara.

The Sardine Run can be depicted as a big event for the Eastern Cape and KwaZulu Natal. Because sardines are virtually toward the base of the food chain, it isn't much of a shock whenever they generate shoals more than 1,000,000 deep that potential predators are usually shortly on their trail. Under the waves, the shoals of sardine are brutally attacked by sharks, tuna, dolphin and even whales. As they come under attack, the little fish form defensive bait-balls it is very little protection because time after time, the predators hit the bait-balls, consuming a number of the little fish with each raid. There are so very many sardines and predators in the water during the Sardine Run that the Natal Shark Board take away the shark nets that generally guard beaches to prevent the sharks, dolphins along with other large sea creatures from getting encircled and dying.

As the shoals come under attack, they're pushed into less deep waters where they start to come under attack from above as the sardines come in range of gannets who join in the abounding banquet that nature has given. Folks get in on the act too. As sardines move to try and dodge the caravan of predators, they swim into shallow waters tiny fishing vessels arrive the fish are literally dragged ashore by clusters of waiting folk. Together with the fishing nets a variety of boxes are utilized to capture the sardines by folks needing to gather as many as they are able to take.

The Sardine Run is a natural event and it is therefore in no way warranted. There weren't any shows recently but each wintertime, the Greatest Shoal on Earth is excitedly expected by people who dwell across the coastline of the Eastern Cape and KwaZulu Natal in South Africa.
