What kind of water movement helps the fishing industry and how?

Upwelling is the process by which deep, cold water rises to the surface of the ocean. This process is important to the fishing industry because it brings nutrients from the deep ocean to the surface, where they can be used by phytoplankton. Phytoplankton are microscopic plants that form the base of the marine food web. Upwelling also helps to concentrate fish by bringing them closer to the surface, where they can be more easily caught by fishermen.

Areas of the ocean that experience upwelling are often rich in fish, including sardines, anchovies, mackerel, and tuna. These fish are important to the fishing industry because they are used to make a variety of products, including canned fish, fishmeal, and fish oil.

Upwelling is a natural process that occurs in many parts of the world, but it is particularly important in areas with strong winds, such as the coast of California and Peru. In these areas, upwelling can occur year-round or seasonally, depending on the prevailing wind patterns.

Upwelling is a vital process for the fishing industry, and it helps to ensure that there is a sustainable supply of fish for human consumption.
