Appreciating The Sardine Run In A Changing World

Witnessing Change In Ecosystems Over Time

The Sardine Run, an incredible natural phenomenon off the coast of South Africa, is renowned as one of the most spectacular marine events on earth. But with changing weather patterns and potential environmental concerns, there’s a growing sense of urgency to witness this underwater ballet before it might change forever.

The Sardine Run is just one example in our worlds ocean of an epic natural migration, where every year, millions of sardines embark on a spectacular migration along the coast of South Africa. This feeding frenzy is a cornerstone of the marine ecosystem, attracting predators like sharks, dolphins, and birds.

This and other awe-inspiring large scale natural events could be facing a challenge: climate change and overfishing.

Temperatures Control It All...

Rising ocean temperatures are disrupting the delicate dance between sardines and their environment. Sardines prefer cooler waters, and as temperatures climb, they may struggle to find suitable feeding grounds. This could force them to alter their migration route or timing, throwing off the entire ecosystem that relies on their predictable arrival.

The Sardine Run shift could have cascading effects. Predators who depend on the sardines for food may struggle to find sustenance. Phytoplankton blooms, which fuel the food chain, could also be disrupted by changing ocean conditions.

The future of the Sardine Run remains uncertain. However, scientists are studying these changes to understand how best to manage the fishery and protect this natural wonder. By mitigating climate change and ensuring healthy marine ecosystems, we can hopefully continue to witness the breathtaking spectacle of the Sardine Run for generations to come.

Overfishing And The Collpase Of The Food Web

Poor fishing management plays a big role in the issue of overfishing globally and it is also having a direct negative impact on the herring stock around Southern Africa.

It should come as no surprise that overfishing depletes sardine populations and disrupts the intricate food web which relies on this fish. In turn, predators such as dolphins, sharks, and seabirds (like the gannet), which rely on the abundance of sardines for sustenance, face food shortages, leading to declines in their populations.

Although not a simple solution – From an economical point of view, some research even suggests that the estimated value of the sardine as a tourist attraction appears substantially higher than could be derived from catching them.
