Fish are abundant in areas where the ocean is upwelling because it -?
Brings nutrients to the surface water. *Dawn.
What industry is dependent upon the productive waters of an upwelling area?
The fishing industry depends on fish gathering at the nutrient rich water upwelling from deeper ocean climes.
Where do near shore zones get their nutrients and what form are these nutrients?
Near-shore zones get their nutrients from the fish and the land around them, the form of these nutrients are animals and plants
Which fish is known as succer fish?
any fish that eats the muck off the surface of rocks or boats or any other object under the water
Can a fish get a tan?
Not as such. But UV light can help epipelagic fish (surface-dwelling; the kind usually found in fish tanks) maintain their natural coloration.

What does upwelling bring to the surface of the ocean?
Upwelling involves a wind-driven motion of nutrient-rich water towards the ocean surface. The nutrient-rich upwelled water stimulates the growth and reproduction of primary producers. This produces more fish for humans.
Describe coastal upwelling and the effect it has on fish populations?
Cooler deep ocean water contains many nutrients. When this water rises, due to upwelling, these nutrients rise to the ocean's surface. These nutrients can then feed fish, providing large regions of successful coastal fisheries.
How is upwelling significant to ocean dynamics?
Upwellings cause phytoplankton and other fish-eaten prey to be able to grow more toward the surface, due to this, more fish are able to prosper closer to the surface and in turn, allow fisherman to fish more as well.
Why are upwelling areas usually very productive fishing areas?
Since upwelling displaces the warmer water with less or no nutrients (located on the ocean surface) with the colder water with more nutrients (located near ocean floor), upwelling water contains more nutrients. These nutrients come from dead or decaying organic matter on the ocean floor, which release nutrients like phosphate and nitrate. When these nutrients are brought up to the surface water, phytoplankton use these nutrients, along with energy from the sun, to perform photosynthesis and produce organic compounds.
How is upwelling important to fishermen?
Upwelling is important because it brings greater concentrations of dissolved nutrients, such as nitrates and phosphates, to the ocean surface. that way fish will go to the top of the water and eat the plankton making it much easier for fisherman to catch a quick bite. :) hope that helps
Why do fisher man like when upwelling occurs?
The cold water contains high concentrations of nutrients produced when dead organisms decayed at depth. This causes fish it be attracted to areas of upwelling.
Why would upwelling zones have large schools of fish?
because they have high nutrient levels
Why is the warm weather condition of El Nino not good for the fishermen?
Under normal conditions, upwelling at the equatorial Pacific brings up nutrients from the deep ocean, which ultimate provides food for fish. During El Nino, this upwelling is reduced or even reversed, leading to fewer nutrients and thus, fewer fish.
Why does the fishing industry watch for upwellings eagerly?
Most ocean waters are depleted of nutrients - plankton gets eaten by larger creatures, the larger creatures export nutrients in their wastes out of the lighted zone, where plants can grow, into the deep ocean. Where upwelling occurs, as in the Peru Current, these deep waters come to the surface carrying nutrients. This yields a phytoplankton boom, which gives fish a rich source of food. The anchovy fishery of Peru, one of the richest fisheries in the world, is directly fed by upwelling. During an el Nino event the upwelling fails - so does the fishery.
Upwelling attracts more fish because?
the system of upwelling pushes water up near the coast for more new fish
How would upwellings contribute to the fishing industry of various nations?
Upwellings in the oceans are associated with the bringing of very nutrient-rich waters to the surface. Those nutrients are the base of a food chain that includes fish. Areas of upwelling are usually extremely prolific fisheries.
