'Upwelling is a procedure which happens in the sea, where cold and nutrient-rich water comes up from the layers below the surface. In such a case there is enrichment of the biological activity and processes. There are a lot of nutrients which means there are also a lot of fishes to eat the plankton that is available. It couples physical and biological processes in fisheries, so in this respect it's important.'
