How does overfishing affect the ecosystem?
In the modern industrialized society we live in overfishing is a big issue because fish is one of our primary sources of protein. Nevertheless, fish is also really important for the ecosystem and its sustainability is vital for the survival of marine creatures and nature.
The human impact on this issue is that we are overexploiting our fish stocks and we fish more than the sea can sustain. We catch too much adult fish in a faster rate than they can reproduce, and, thus, we don’t leave enough to breed and reproduce. Therefore, their population can’t recover and many species of fish get extinct because of this. We do this because

Human’s influence on marine life isn’t just in the water, but it in some cases transfers to rivers which affects plants and trees in the nearby areas, so terrestrial life is also affected. For example, in Trang River Estuary in Thailand mangroves are affected by polluted water because of overfishing nearby. If we want to be more precise, it was commercial farming and it was because of shrimp. From 1975 to 1993, it is estimated that about half of Thailand’s mangroves along its 2,560 kilometer coastline have been lost. This coastline is really important and vital for more than 200 hundred bird species, some of which are really close to extinction and seriously endangered, but nothing can be done because large industries have enough money to hide those facts and remain innocent in the eyes of the law. ('What Is Marine Pollution And How Does It Affect Marine Life’) All this could result the collapse of whole ecosystems and affect not only us and our food supply, economics and life, but also some biotic factors like other species. ('10 Alarming Facts about Overfishing') This could be a interspecific relationship because it is among different species. We are parasites to the fish because the benefit from them, but they lose from our influence. The human’s impact with overfishing has come to the point when National Geographic reports, “A study of catch data published in 2006 in the journal Science grimly predicted that if fishing rates continue apace, all the world’s fisheries will have collapsed by the year 2048.” By 1989, when about 90 million metric tons of catch were taken from the ocean, the industry had hit its high-water mark, and yields have declined or stagnated ever since. All this and we are still destroying and exploiting our main food source. ('Overfishing -- National Geographic')Not only this, but tax
First of all, the article Too Many Fishermen enlightens the readers about the dangers and risks of overfishing. For example, on lines 12 through 15 it states, “Overfishing depletes fish stocks by taking fish at a rate faster than they can replace themselves. Many fish are harvested before they are even mature enough to reproduce. As a result, marine species are dying at an alarming rate.” The author used this evidence to better show how real and harmful the situation is. This is used by the author to help support the idea that humans have a negative impact on the ocean and helps to spread the word easier.
Overfishing is defined as a form of overexploitation where fish stocks are brought down to unacceptable levels. In the UN Food and Agriculture Organization’s 2 yearly report (SOFIA), it states how over half of the fish stocks, worldwide, are fully exploited. Other research has shown it only takes 10-15 years of industrial fishing to obliterate a tenth of the intended species. Overfishing causes a ripple effect that hurts the entire ecosystem. The balance of the chain depends largely on the interaction between the predator and the prey.
Overfishing can lead to sea creatures becoming extinct. This can ruin an entire food chain and continues
Earth's oceans make up over 75% of the Earth as a whole. With that being said, it is vital to understand the significance on the contents of the oceans. Since fish and marine products make up a large portion of our diet, fishing practices need to be properly managed. In this essay, overfishing will be defined, its consequences will be revealed, and plans for proper fish distribution will be executed.
Overfishing may have some benefits to it, but does it out way the negatives? By fulfilling our demand we can wipe out our whole oceans! Not just the fish, but water mammals too. Sure it can create jobs, but as what cost? It can help bring up our economy, but at the same time it can bring it down with many fish companies closing down due to lack of profit. Fish is a great source of nutrients, but too much can kill you! In other words, fish can be both beneficial and harmful to not only humans, but everyone and everything surrounding fish. There are three things people can do to help with overfishing, the first thing is to be aware of what you are eating. Is the fish on the fear of extinction list? Also asking yourself is the fish you’re about to eat really the fish you intend to eat? Another thing to ask is, was it shipped over seas? If it was it doesn’t benefit anyone, it won’t help the economy or you. Many fish shipped from a long ways creates pollution and may have lost its nutrients value from the long voyage. One last thing to do is if you see a sewer with a sign leading to the ocean, try not to leave trash near it, or better yet don’t litter at all! All the litter left out on streets or near sewers can cause pollution in oceans, lakes, and rivers which is very harmful for marine life. You can still enjoy fish, but not at such a high demand as
Overfishing refers to an act of fishing more than what the population can replace through normal reproduction (WWF, 2016). This was led by international government efforts to increase fishing capacity in the mid-20th century, which then led to the increase in availability and affordability of protein-rich foods. With this, profitable commercial fleets became aggressive, scouring the world’s oceans and developing sophisticated technologies to find and catch their targeted species. Thus, with a wide selection of fish species available at affordable prices, customers soon became used to them (Geographic, 2016).
I chose to discuss overfishing as my topic. The definition of overfishing is: form of overexploitation where fish stocks are reduced to below acceptable levels. Overfishing can be broken down to three main categories: overcapacity of vessels in the water, unsustainable fishing and food needs. Overfishing can occur in bodies of water of any shape and size.
There are many impacts that fishing and land animal farming have on the ocean, which are detrimental to ocean ecosystems as well as many other aspects of the environment. Overfishing, killing fish at a much quicker rate than the fish can repopulate, is one major problem. Three-fourths of the world’s fisheries are either fully exploited, overexploited, or depleted (Cowspiracy). Researchers have estimated an end of all viable fisheries by 2018 if the current trends of fishing continue (Mason). According to the Monterey Bay Seafood Watch, hundreds of thousands of animals die every year as bycatch, with one of the worst offenders being shrimp fisheries, catching up to six pounds of bycatch per pound of shrimp. Endangered species are also caught, including predators which are important in keeping the balance in ocean ecosystems (Smith). While many organizations such as the Monterey Bay Aquarium Seafood Watch recommend consumers to eat more “sustainable” fish, this will not stop the massive environmental impacts. Sustainable fishing for one does not account for the natural flux in the population of species of fish; what is considered a sustainable amount of fish to harvest one year may deplete the fishery in another year (Smith). Sustainable fish also are becoming even less sustainable as companies that label sustainable fish must find more For example, after Wal-Mart pledged to selling Marine Stewardship
Overfishing is a growing world problem. In 2013, 93 million tonnes of fish were caught
Now, fish is sold at almost every grocery store and a popular food today. However, over-fishing is a problem going on in the ocean today. It kills coral reefs and endangers different species of animals. Although fishing supplies humans with a substantial amount of nutrients, it is important to realize the detrimental effects it can have on the ocean too.
Future – In the near future the Debate might be still won by Overfishing but in the far future Climate change has every single possibility to be one of the major reasons not only for the depletion of fishes and other life but also every single concern that is considered to be small. The non veg population is likely to decrease due to these consequences and this might hit the non veg food industry.
Overfishing is the most major problem related to oceans, but it is also the most overlooked. Fishing has been going on for thousands of years, and fish have always been seen as a renewable resource, that would replenish itself forever for our benefit. But around the world there is evidence that fish are not recove...
“Group members express themselves in a multitude a different ways ranging from productive to destructive (Griffith, Dunham, 2015, pg. 47, par. 4).” There are social behaviors that are developed when teams come together. There are four social style classifications, analytic, expressive, driver and amiable. The analytical social style are more precise and clear in whatever direction they need to complete a job (Farrington, 2013). Analytics will always be prepared for a task because the very nature of their behavior is to be astute and calculating. The upside to this social style is that their research or work is usually dependable but they also may not be open to criticism which can stifle progress. Expressive team members are involved heavily with interpersonal interactions (Farrington, 2013). Expressive people need to be and will be heard. The value in the expressive social style is that simply they are fun to be around and can be the cheerleader in the group which is conducive to team building.The down side to the expressive social type is that their interpersonal actions may not be the most focused in a group and therefore they are not usually the most dependable team member. The driver social style are more efficient and goal oriented (Farrington, 2013). A team member who is a driver is more than likely a leader but should not be allowed to supercede the actual team leads authority. Amiable members in a group value personal relationships and try to avoid conflict (Farrington, 2013). An amiable team members is primarily just that, a team member. It is important that team leaders identify which social style that their team members has and conduct business with said members accordingly
The first cause of the marine extinction is coming from over-fishing and commercial fishing. According to Marine Extinction and Conservation, commercial fishing has
As stated above, there are a multitude of causes for this “mass extinction”, and most all of them are caused by humans. One such causality is overfishing. Everyone loves to eat fish. However, with overfishing, humans are collecting more fish than we can consume as a population. Overfishing is when people collect more fish from the o...
