The ocean currents are related to the fishing industry.
Ocean currents can be affected by land currents and also by the temperature of the oceans.
These forces are strong enough to influence the distribution of plankton which is the food source for the fish.
Warm ocean currents restrict the growth of plankton hence give rise to poor fishing grounds.
Cold ocean currents encourage the growth of plankton (small plants) as they are rich in nutrients.
The fishing industry uses this information to find out about the best fishing areas, which are the warm water currents.

Do fish get caught in currents?
Climate fluctuations lead to shifts in ocean circulation that cause fish populations to rise and fall.
How ocean currents influence the formation of fishing grounds across the world?
Ocean currents influence the formation of fishing grounds across the world. Mixing of cold and warm ocean currents bear richest fishing grounds in the world. Examples: Grand Banks around Newfoundland, Canada and North-Eastern Coast of Japan. The mixing of warm and cold currents help to replenish the oxygen and favor the growth of planktons, the primary food for fish population.
Do fish create currents?
The organ in many electric fish can produce differing EODs depending on the function. Polarized arrangement of electrolyte cells in some eels (for example the electric eel, Electrophorus electricus) allow the generation of small voltages that can build or add up creating weak or strong currents.
Bottom trawling literally scrapes the ocean floor clean of life and is considered by some to be the underwater equivalent of clear cutting forests. Bottom trawling is the act of fishing by dragging a trawl net through the ocean floor, scooping up the fish and sea life in the process. The process is quite destructive to the ocean floor and can also be an extremely dangerous practice.
How does current affect fishing?
Most species of fish bite better on a moving current. But not all species of fish are the same. Some species will bite better on the change of the tide. Some species will bite right through the tide and current change but will significantly alter their feeding behavior as the change occurs.
How do ocean currents affect living things?
By moving heat from the equator toward the poles, ocean currents play an important role in controlling the climate. They also play a crucial role in the distribution of nutrients and food to organisms that live permanently attached on the ocean floor. Additionally, ocean currents are critically important to marine life. They carry reproductive cells and ocean life to new places.
How do commercial fishermen catch fish?
Commercial fishing is a very large industry in which a large number of fish are caught daily. For example, in the United States, commercial fishermen catch 3.5 billion fish per year and each year they catch close to 2 billion pounds of fish. This is a very large industry that can be easily expanded with the right tools and equipment.
How do fish use ocean currents?
Currents affect the availability of nutrients for plant growth, and thus the availability of food for marine animals. Eggs and larvae of fish and other animals drift with the currents from the spawning grounds to nursery areas where they feed and grow.
How do ocean currents affect the marine environment?
Ocean currents are important in marine ecosystems because they redistribute water, heat, nutrients, and oxygen about the ocean. At the same time, currents inevitably sweep over and carry off living organisms.
Do fish follow ocean currents?
Fish, like all other living organisms, follow the ocean current. If the ocean current shifts, the fish must alter its course as well. The direction of the ocean current depends on the density of the water in the surrounding area. During a rapid change in ocean current, fish can be at a disadvantage.
Do currents affect fish?
Yes, currents do affect fish. Typically, most species of fish will bite better on a moving current. However, it’s important to note that the bite is usually better when the tide is changing. Some species will bite right through the change of the tide. It’s recommended that you avoid going in for a bite if the current is on the rise. The rise may cause some species to bite aggressively, sometimes even at the wrong time.
How do currents affect animals?
Currents are important in marine ecosystems because they redistribute water, heat, nutrients, and oxygen about the ocean. At the same time, currents inevitably sweep over and carry off living organisms. Most of the time, currents do not affect animals. However, currents can cause changes in the ocean’s temperature, oxygen content, and salinity. These changes in the environment can cause some animals to become displaced or die.
How do ocean currents affect fishing?
Ocean currents are important in the fishing industry as they affect the growth of plankton which provides fish food. Warm ocean currents restrict the growth of plankton hence give rise to poor fishing grounds. Cold ocean currents encourage the growth of plankton (small plants) as they are rich in nutrients.
