Why are many fishing boats found near ocean upwellings?

• There is less vegetation there.

• Upwellings are found in more shallow waters, so boats do not need deep anchorage.

• The water is less turbulent there.

• The upwellings bring up nutrients, causing phytoplankton blooms and corresponding increases in populations across the food web including commercial fish populations.
