Powerful motorised winch cranes can haul in huge nets full of fish.
Netting: Monofilament nets are hard for fish to see. They can stretch for more than 40 km and hang like massive curtains in the water. Trawl nets scoop fish from the bottom of the sea floor.

Fun Fact!
According to the World Food and Agriculture
Organisation (FAO), there are 38 million fishermen or fish farmers in the world today.
The infographic below gives a number of reasons why fishing must be done in a sustainable way.
Overfishing means that three-quarters of the world’s fish stocks are being harvested faster than they can reproduce. If current trends continue, the world’s food fisheries could be completely eliminated by 2050. A sustainable solution is vital.
