Over two billion people around the world rely on fish as an important source of protein. This is astonishing when you consider that our piscine prey live in an environment in which we will always be outsiders. But humans have risen to the challenge and now use everything from nets to trawlers, and spider webs to dolphins, to catch their dinner.

Boys scare fish into a tight ball and then dive to the bottom of the reef to net their catch in Palawan, Philippines.
A tightrope makes it easier to catch fish in the Mekong river during monsoon season.
During monsoon season the Mekong swells to 20 times its normal volume which brings more fish but makes them harder to catch. Sam Niang built a tightrope to reach the best fishing perch.
To avoid the Zambezi's dangerous animals these brothers have found an alternative place to fish.

The fishermen of Laguna in Brazil have forged an extraordinary fishing partnership with dolphins.

It is every man for himself in the fishing frenzy as Lake Antogo is emptied in minutes.
On one day of the year the Dogon people of Mali can fish in the sacred water of Lake Antogo. It’s every fisherman for himself as the lake is emptied in minutes.
One of the most dangerous fishing methods of all. A crew in the Philippines dive to 40 metres, breathing air from a rusty compressor.

Around one billion people around the world rely on marine fish as an important source of protein and even more rely on fish from rivers and lakes. In Cambodia, for example, a whopping 95% of a person’s daily protein might come just from freshwater fish.
The fact that we can’t breathe underwater has forced humans to be incredibly creative in their hunting and we now catch fish in a truly astonishing number of ways, some small and personal, others huge and industrial.
On the islands of Papua New Guinea, for example, men known as “shark callers” lure their prey by singing to them while rattling the shells of coconuts. Further east, in the Solomon Islands, men simply float in the water and drop weighted lines below them. With stealth and accuracy, they are able to catch fish hiding in the reef below.
In Malaysia, the Bajau Laut are more immersive. Their free-divers can swim 20 metres down on a single breath, and stay there for several minutes as they hunt their prey with spear-guns. But even more dangerous is the work of the Paaling divers of the Philippines. They dive to depths of 40 metres, breathing air that is pumped down to them through a garden hose.
But at least they have tropical sunshine to warm them up. The Nenets of northern Russian must lower nets through thick ice when they want to catch fish. And when it comes to disentangling them, the nets are so delicate that the fishermen must take off their gloves and use their bare hands, a bitingly painful experience in such freezing temperatures.
The need to catch fish has even inspired humans to form partnerships with other animals, some tame and some wild. On the Ganges, for instance, tame otters are used to scare fish into waiting nets, while fishermen in China employ the services of cormorants. By tying ropes around the birds’ necks, they make sure that the trained birds can’t swallow their catch before they do.
But perhaps the most equitable - and amazing - of partnerships is found between the fishermen and wild dolphins of Laguna, Brazil. Here, the dolphins shepherd shoals of mullet towards the shallow water where the fishermen await with their nets. When the fish are within striking distance, the dolphins jump out of the water, letting the fishermen know that it is time for them to throw their nets. As the mullet break rank, the dolphins can then pick off the errant fish one by one.
Of course, not all methods of fishing are quite so sustainable. Thanks to industrial fishing techniques, the trade in fish and seafood products is now worth billions of pounds a year and fish are now among the most widely traded commodities in the world. Perhaps because of this it is now estimated that as much as 90% of all the oceans’ large fish may already have disappeared. Not only is this likely to take its toll on our ocean ecosystems, it is also likely to impact badly on our own future food resources.
