EXCLUSION NET VS SHARK NETS

Two completely different ways of preventing shark attacks.

Many people get confused between shark exclusion nets (barriers) and traditional shark nets but they are actually two completely different ways of preventing shark attacks. Traditional shark nets are a fishing device and a form of lethal control of sharks that can have negative consequences for the environment.

Shark exclusion barriers (nets) are a non-lethal, environmentally responsible form of shark control that have far fewer negative environmental impacts, if any. The net in Fish Hoek is a shark exclusion barrier.

Check out the table below showing the main differences between shark nets and exclusion nets

Shark Net Exclusion Net
What are they?
Shark nets are large-meshed, anchored gill nets
Exclusion nets are fine-meshed nets acting as barriers
How do they work?
Lethal shark attack mitigation measures
These are fishing devices designed to catch and kill sharks, reducing the population and numbers of sharks within the environment and thereby reducing the risk of shark attack
Non-lethal shark attack mitigation measures
Fine meshed nets are designed to act as a barrier, physically excluding sharks, thereby preventing them from entering an enclosed area. They are designed not to catch any animal species.
Layout and structure
Floating sections of net approximately 215 – 305 m long by 6 m deep
Mesh size of 50 cm (stretched) in a diamond configuration
Set parallel to the coast in 10-14 m of water approximately 300-500 m from shore.
Do not prevent sharks from entering an area, sharks can swim around them and under them.
Net stretched from the seafloor to the sea surface, enclosing a specific area.
Prevent sharks and other marine animals from entering an exclusion zone.
Mesh size is small, only 4 cm in a square configuration.
Size of net is dependent on area to be enclosed.
Entanglements of marine animals
Not selective and result in by-catch of a range of other marine species such as nondangerous sharks, rays, turtles, dolphins, and whales. Risk of entanglement and mortality is HIGH.
The fine mesh of the nets prevents capture or entanglement of marine species and the net acts as a barrier. Risk of entanglement and mortality is LOW.
Ecological impact
High
Low
