Everything you need to know about Shark Nets with Wayne

KZN Sharks Board's Wayne Harrison shares ocean safety tips and the secret behind the shark nets and how they work.

As you sip your morning coffee, have you ever pondered how those mysterious shark nets, which promise safety along swimming coastlines, actually operate?

You’re not alone. Many, including the team at East Coast Radio, have these burning questions.

Darren, Sky and Carmen had the privilege of interviewing Wayne Harrison from the KZN Sharks Board, whose expertise shed light on this subject.

Harrison unravelled the mystery of shark nets by explaining, “We have what we refer to as Shark Safety Gear from Richards Bay in the north to strategic beaches extending down to Port Edwards in the south.”

However, he clarifies, this doesn’t mean the entire coastline is secured. Only specific strategic beaches are covered.

Historically, shark nets were the primary method used, but innovation led to a combination of nets and drum lines, as Harrison describes, “In recent years, we’ve changed from nets through to next gear. So that means nets and drum lines.”

Why the nets and drum lines change seasonally

The dynamic ocean environment means that the equipment doesn’t stay constant throughout the year.

As Harrison elaborates, "In the summer, we target bull sharks with mixed gear, nets, and drum lines. But when winter rolls around, changes occur to accommodate the migration patterns of certain whales, and the annual sardine run."

From the beginning of May, nets are removed to avoid entangling whales or marine mammals, while drum lines are neutralized during the sardine run.

This precaution reduces the risk of unintended captures, demonstrating the Board's commitment to marine life conservation.

Misconceptions about shark nets and shark behaviour

A common misconception that Harrison wishes to correct is the belief that shark nets form a complete and impenetrable barrier in the ocean.

He points out, “The nets are reduced at the end of summer, and they’re situated to reduce risk rather than block all sharks.”

Furthermore, he highlights the importance of public awareness regarding ocean dangers during these seasonal changes.

Swimmers are advised to pay heed to their surroundings and consult lifeguards before diving into the water.

Harrison concluded, "It’s crucial for ocean goers to recognise that during certain times of the year, like the sardine run, no protective gear remains.”

Exercising caution and staying informed are essential.
