We also support the use of aerial patrols of our beaches in Summer to help warn beach-goers if any sharks are around.
A summary of some other potential technologies are below.
Shark Enclosures:
Shark enclosures provide an enclosed, unbroken full length net across the beach. The size of the mesh is much smaller than shark nets, protecting marine life from getting tangled.

Shark Shield:
Shark shield emits an electrical wave that reaches up to 8 metres from the device. This wave is picked up by the ‘Ampullae of Lorenzini’ (gel-filled sacks on the sharks snout), and creates discomfort for the shark. The closer the shark comes to the device, the more unpleasant the experience is, therefore, deterring the shark. Once the shark is out of range, there are no lingering or harmful after affects.

Sonar Systems:
There are many sonar systems that will detect a shark before it gets close to the shore. Once the shark is detected, boats and helicopters are sent out to herd the shark further away from the shore or lifeguards are notified to evacuate the beach.

Keep up the good work! Raising awareness is the first step!
ReplyDeleteI don't understand how we can actually be so cruel, there are living things out there too that deserve to live. Humans are the most selfish animals on Earth, honestly! I speak as one, not perfect, not even close, but there needs to be a change!!! Choosing to use nets because it is cheaper than the other alternatives that are much safer for our marine life! We are killing this earth bit by bit, why is nobody doing anything about it. The earth is now a ticking time bomb, and humans are what are causing it to happen!
ReplyDeleteEarth has been around for 4 billion years, survived meteor strikes, planets crashing into it, ice ages, and many other natural catastrophes but shark nets, thats going to kill it, bit by bit
