Drum Lines and Shark Nets: Death Traps in Our Seas
A Conservation Conversation by Petro Diamant – Artist | Earth Ambassador | Wildlife Advocate
The ocean is not ours. It never was.
Yet along our coastlines, drum lines and shark nets are strung like silent traps, cruel reminders of human fear disguised as safety. These devices do not discriminate. They catch and kill sharks, dolphins, turtles, rays, and whales alike. Lives meant to move freely through the blue are reduced to statistics, rotting beneath the surface.
Every creature entangled is a being that once played a vital part in the ocean’s heartbeat. In the ocean’s health. Sharks that keep ecosystems in balance. Turtles that tend to seagrass meadows. Dolphins that guide their pods through life and song.
We are not protecting swimmers, we are culling, killing, we are punishing the sea.
The ocean is their home, their world, their birthright. We are visitors, and guests should not destroy the homes they enter. There are modern, non-lethal alternatives: shark spotters, drone surveillance, sonar detection, magnetic repellents. Compassion and science can coexist. It has to for the sake of wildlife and the ocean.
If we cannot swim without killing, then we have no business entering the water.
Be Kind to Animals. Be a Guardian. Be a Friend.
Drum Lines and Shark Nets: Death Traps in Our Seas
A Conservation Conversation by Petro Diamant – Artist | Earth Ambassador | Wildlife Advocate
Introduction
The ocean breathes life into this planet. Its tides pull the moon, its depths cradle entire worlds unseen. Yet within this vast living realm, humanity has placed unconscious and invisible weapons – drum lines and shark nets, meant to kill what we fear, rather than understand.
I have seen the photographs, the twisted bodies of marine life caught in nylon and steel. Sharks, dolphins, sea turtles, rays, each one a victim of our illusion of control. We call it “protection,” but what we have built is a trap. A culling system labelled under false pretence and lies.
The truth is simple: the ocean belongs to its inhabitants. We are land-based visitors. When we step into the sea, we enter their home. It is their home. And to kill the residents of that home in order to feel safe in it is not protection, it is cruelty disguised as precaution. It’s selfish. It’s destructive.
The Hidden Killers
Shark nets and drum lines are marketed as “safety measures” to protect humans from shark encounters, particularly in popular swimming and surfing areas along coastlines like South Africa’s KwaZulu-Natal. But these devices do not create a barrier – they simply kill. Cold blooded killing so that we can swim in waters that don’t belong to us.
Drum lines are baited hooks suspended from buoys, designed to catch and kill large sharks. Shark nets, often hundreds of metres long, do not form a wall of safety. They are fishing devices that entangle anything unfortunate enough to cross their path – sharks, whales, rays, turtles, dolphins, even harmless fish and seabirds. Innocent marine life.
According to conservation reports, thousands of marine animals die every year due to entanglement in shark nets and drum lines. Many of these species including great white sharks, tiger sharks, loggerhead turtles, bottlenose dolphins, humpback whales, and manta rays – are already classified as threatened or endangered.
For every shark caught, countless non-targeted animals perish – their deaths hidden beneath the waves, unseen by the very people who believe the nets are keeping them safe.
The Price of Fear
Fear has never been a good teacher. It causes us to do stupid things. It causes us to harm others especially animals.
Our fear of sharks – magnificent apex predators vital to marine ecosystems – has been magnified by decades of misunderstanding. Decades of fear and stupidity. Sharks do not hunt humans. Most encounters are accidents, cases of mistaken identity. Yet our fear has created a war against the ocean’s most misunderstood guardians. I know the fear for sharks. I feel it and I don’t wish them harm. I know that when I go into the ocean that I’m in someone’s home.
When we destroy sharks, we unbalance entire ecosystems. Populations of smaller fish and rays explode, coral reefs degrade, and marine biodiversity declines. The ocean’s equilibrium – which stabilises our entire planet – begins to collapse.
And for what? For the illusion of safety. At the cost of animals being harmed and species going extinct.
We have made the ocean pay for our inability to coexist. Our ignorance, our selfishness our fear. But coexistence is not only possible – it is essential.
There Are Better Ways
Around the world, non-lethal alternatives have already proven successful. In places like Cape Town, the Shark Spotters programme uses trained observers to watch the water from elevated points, alerting swimmers when sharks are near. Drone monitoring, sonar systems, magnetic and electric repellents, and even personal shark deterrent devices have all been shown to reduce encounters without taking lives.
Education also plays a crucial role. Understanding shark behaviour, respecting no-swim zones, and avoiding certain conditions can drastically reduce risk. Humanity must learn to adapt rather than destroy.
Our oceans can thrive – and so can we – if we choose compassion over control.
A Home Shared, Not Owned
The ocean is a shared home. Every creature – from the tiniest plankton to the mighty whale – has a role in maintaining its rhythm.
When we enter the sea, we are guests. Guests do not kill their hosts. Guests do not tear holes in the walls of the home that shelters them. Intruders and imposters do that.
To swim in the ocean is to enter a blue cathedral of life – one that existed long before us and will outlast us, if we allow it.
The sharks, the dolphins, the rays and so many other species – they are not intruders. They are the heartbeat of the blue. And their survival determines our own.
Conclusion
If we cannot swim without killing, then perhaps we are not ready to swim at all.
The ocean’s beauty lies in its wildness – in the living, breathing world beneath the surface. Drum lines and shark nets betray that beauty. They betray the very balance that allows life to exist on this planet.
It is time to choose respect over fear, coexistence over control. The ocean does not belong to us. But we can belong to it – in peace.
Be Kind to Animals. Be a Guardian. Be a Friend.
