세계 4대 어장? 그런게 존재하나?

The world’s major fisheries. 

Red areas are major fisheries;
the darker the red, the greater the harvest and the more important the fishery.
Most major fisheries are in areas of ocean upwellings,
where currents rise, bringing nutrient-rich waters up from the depths of the ocean.
Upwellings tend to occur near continents.
