To keep our oceans healthy, we need to use fishing methods that keep fish stocks healthy and protect other marine creatures. Sadly, industrial fleets have been overfishing and using gear that destroys marine life. Protecting our oceans means changing the way we catch fish.


Decades of bad fishing practices have left our oceans in a tragic state. Many species which were once common-place are now threatened, dwindling to the point where there aren’t enough to catch and make a profit. Over 90% of predatory species like cod and tuna have already been caught and, according to the UN, 70% of fisheries are overfished.

Numbers of fish are dropping faster than they can reproduce and this is causing profound changes to life in our oceans. In reality, there aren’t plenty more fish in the sea.

The fishing industry has become high-tech and giant ships use sonar to find fish schools with pinpoint accuracy. Huge nets catch fish in vast numbers. These ships are also floating factories, with processing and packing plants to handle their catch more efficiently. All this means there is now capacity to catch many times more fish than are actually left.

Overfishing is emptying the seas

As traditional species disappear, other species are targeted and even renamed to make them more appealing. For instance, the Patagonian toothfish was reinvented as the more appetisingly named Chilean seabass. Fleets are also venturing into more distant waters in the Arctic and Antarctic oceans to ravage fish populations there.

Fishing methods used by these ships are often very destructive. Bottom and beam trawling drag nets across the seabed to catch flat fish like hake and sole. But they also smash everything in their way, destroying fragile coral reefs. And most fishing methods are very indiscriminate, catching many other species by accident. This ‘bycatch’ includes turtles, sharks, dolphins and other fish, which are often thrown back dead or dying into the sea.

There’s a human cost too. Industrial fishing means small-scale fishers using more traditional methods are suffering. In the UK, smaller boats are finding it hard to make enough money and communities in many fishing ports are economically deprived. The number of fishers has also halved in the last 20 years. Elsewhere in the world, people who depend on fish for food and income are seeing their stocks disappear as foreign vessels trawl in their waters.

Unfair fishing quotas

The way the UK government allocates fishing quotas plays a big part in this. Quotas have become concentrated in the hands of a small number of multi-million pound companies. Just five families control nearly a third of UK fishing quotas and more than two thirds of fishing quota is controlled by just 25 companies. Compared to smaller fishing operations, these big companies employ fewer people, use less sustainable fishing methods and less money makes its way into local economies.

Our government already has the power to change the way it distributes quotas. Greenpeace is campaigning for a fairer allocation system that favours local, sustainable fishing which will help create jobs and allow fish stocks to recover.

We’re also taking on the corporate giants plundering our oceans. Thai Union, the biggest tuna company in the world and owner of John West, was turning a blind eye to appalling conditions for workers and destructive fishing practices. But then an outcry from thousands of people around the world forced Thai Union to clean up its operations.

And we need to create more protected areas at sea. A network of ocean sanctuaries will provide refuges for fish and other marine life to thrive away from the threat of industrial fishing fleets. With climate change creating other threats to our oceans, we need to give them all the help we can.
