Why are shark nets ineffective?

Firstly, they found shark numbers have declined, both for species targeted by nets (tiger, white and bull sharks, all of which are threatened or near threatened) and for non-target species also caught in nets.
Do nets stop sharks?
Shark nets are most effective at reducing the abundance of resident sharks as these sharks have a higher chance of encountering the net over time. They do not prevent sharks from entering or leaving the beach; they operate by entangling sharks that swim into them by chance.

How do sharks stay safe at the beach?

Should you yell at a shark?

Sometimes yelling underwater or slapping the water repeatedly will scare the shark away. Conserve your strength for fighting in case the shark attacks. If attacked, kick and strike the shark.

How can we protect people from sharks without killing sharks?
