Fisheries And Oceanic Food Chains

Overfishing is a death sentence to the world’s oceans. As technology continues to improve a great deal of fish can be caught quicker; but at what cost? The effects of overfishing can lead to the extinction of not just the animals being fished, but also the predators that rely on fish to eat. Ninety percent of the ocean’s largest animals have been wiped out due to overfishing (“Overfishing- A Global Disaster”, 2011). National Geographic cites the academic journal Science (2006) that predicts by 2048, all fisheries will collapse due to lack of ocean wildlife. Fish are not the only animal caught in the nets used by fishing vessels. Often animals such as dolphins, sharks, turtles, and seabirds are

Callum Roberts set himself the difficult task of cataloguing evidence that today’s oceans are depleted and struggling against overfishing and human influence, while still remaining optimistic about the future of the world’s oceans in his book The Unnatural History of the Sea. Roberts begins by painting a picture of the oceans as they may have been before human influence had drastically depleted species and changed ecosystems through fishing. From this point, he maps out centuries of development in fishing and shows how drastically changed and depleted the world’s oceans are today because of human exploitation. With the explanation of modern day fishery policy and a strong case against the practice of trawling, Roberts shows how humanity continues to exploit the ocean as if it were an endless resource. In spite of all this, the author, in the end, attempts to develop a positive outlook by explaining what can be done to stop the rapid decimation of fisheries, including reevaluation of fishery regulations and development of marine reserves.

According to a study done by Living Planet Report in 2015, 29% of the world’s fishing stocks are considered overfished and an additional 61% is fully exploited with no possibility to produce more fish. Our environment is currently afflicted by a number of different problems, one of which is overfishing. Overfishing is defined by FishOnline as, “Fishing with a sufficiently high intensity to reduce the breeding stock levels to such an extent that they will no longer support a sufficient quantity of fish for sport or commercial harvest.” The overfishing situation is being exacerbated by non-sustainable and destructive fishing practices and unfair fisheries partnership agreements; while there are currently attempts being made at fixing these problems and their effects on overfishing, nothing has been extremely effective.

Overfishing is a threat not only to marine ecosystems, but also to human survival. If there are no fish, humanity will have to find alternative food sources, which, with our current technological capabilities, are not readily available nor easily accessible for the general population, potentially leading to widespread famine. Our advertisement highlights how soon this may become reality, with the statistical claim of scientists predicting the oceans to be completely lifeless by 2050. People may feel that our claim is more legitimate if it has been confirmed by professionals. The prediction alone is grim, and our choice to use the

The National Geographic article, “Time for a sea change”, by Paul Greenberg, discusses the global fishing industry’s unsustainable fishing habits. It examines fishing companies’ appetites for luring fish out of the sea, then selling fish to people to make revenue, and ultimately consuming more than the sea produces. As the industry is taking so much fish out of the sea, Seafood Print (a study supported by the Charitable Trusts and the National Geographic channel) is investing the repercussions if these practises keep progressing in the long term.

Some believe that the laws applied to prevent overfishing aren’t enough and they argue that there is a lack of public awareness and political attention. Alex Rogers, professor of the conservation biology at UK’s Oxford University, highlights the fact that most of the ocean world is not under major jurisdiction of major countries, therefore, there is a problem enforcing environmental laws in the ocean. Robert sums up a solution of the problem being fishing less, with more suitable measures, polluting less while also remain in terms of sustainability and environmental protection.

Millions of people rely on fishing for their livelihood and nutritional needs. For decades, oceans have provided us with a bounty of seafood for these needs, but there is a limit to everything. Unsustainable fishing practices and overfishing over the last few decades have pushed our oceans to the limit and they may now be on the verge of a collapse, thereby affecting the everyday way of life and source of income of those who depend on them. With no productive fish left in the sea to fish, fishermen and fisheries are bound to go out of business in no time.

It’s instinctive for people to want to conserve and protect the earth. People are beginning to care more about our earth and what our actions create. People who live off the sea or depend on fish for survival are aware of overfishing. They can’t help but be affected. They know it’s becoming a larger problem now than in the past. People want to preserve nature, and see all wildlife thrive. That’s why there are some regulations about what species can and cannot be fished. Fish hatcheries are asked to only produce a certain amount of fish. Certain parts of the ocean cannot be fished, while some species are illegal to catch and keep. Some parts of the world even regulate which days fishing is allowed. Rules such as these protect fish, and I believe they will get more and more common as time progresses and the world population increases. We’re taking responsibility, and moving towards correcting our error. The world is not as heartless as Home made us

The overharvesting of marine organisms has been an ongoing issue since the mid 20th century, but has never been more prevalent until the present day. Fishing in the 20th century was a massively rapid-growing industry. Because of international efforts aimed at increasing the availability as well as affordability of foods rich in nutritional value, government intervention took place to increase the availability of fish species to the human population. With the implement of policies, government loans and support, there was a dramatically huge increase in industrial fishing—eventually making marine organisms the world’s primary source of protein-rich foods. This was good for a while, but obviously, good things never last too long. Overfishing, as defined by Pepjin Koster, occurs when more fish are caught then can be replaced through natural production (Koster, 2012). The balance of life in oceans is affected, and the social and economic well being of

We are currently in danger of facing the sixth marine life extinction due to overfishing. Ocean life plays an important role in the human environment. Roughly three quarters of our planet is covered in oceans, giving us the oxygen and fresh air in the atmosphere that we need. A major extinction of fish in oceans around the world can cause dangerous harm to ecosystems, and negatively affect the lives of humans around all areas.

Did you know that 91 percent of important commercial marine species have had their population cut in half since 1800 (Biello)? Commercial marine species include the plethora of beautiful fish species under the sea. It also includes the fish used to make your favorite sushi or fish sandwich. But if overfishing continues, your food will not be the only thing affected. Overfishing is causing drastic and dangerous changes in marine ecosystems, increasingly affecting the global economy in a negative way, and putting millions upon millions of people at risk of food shortages and poverty. As a solution, international fishing laws and regulations need to either be better enforced or changed altogether to better safeguard our seas.

Overfishing began in the early 1800’s when it was discovered that whale blubber could be utilized for oil lamps. Overfishing is when fish are taken from the ocean at a rate that is too fast for them to adequately repopulate. In contrast to every damaging anthropogenic activity, overfishing has taken the biggest toll on the marine ecosystems and has led many fish species to reduce rapidly and others to become extinct. In order to stop this before it is too late, we must enforce sustainable methods, and eliminate the use of these extremely damaging procedures. Overfishing is a global issue, that has resulted in economic loss, marine life disruption and decreased food security, by supporting sustainable methods and campaigning to ban our

For thousands of years, humans have been relying on the ocean of their living. In some areas along the coast, people’s lives depend on the sea. People living in those areas use fishing as their main business. They got many profits by this economy and they could live wealthily. However, the technology has been improved so much that the fishermen use different techniques to catch the fish. This leads to getting them more money but on the other hand, it causes over hunting. In some places, people have been overfishing with their equipment using new technology such as radar and sonar. People hunt for huge profits; over time, they fish much deeper and catch them more rapidly. Some species have gone to extinction due to overfishing. However, in Alaska, Alaskan fish are some of the least contaminated in the world, and the salmon population continues to thrive despite the yearly fishing.

If we continue to overfish, several aquatic species may become endangered, or maybe even extinct. From there, the damage will be irreversible. The aforementioned problems will then be a reality. However, if we stop overfishing now, then those issues will become very minor and can be easily solved. By putting an end to overfishing, the fisheries won’t have to stop operating, but they will have to limit the amount of fish they catch. Ocean ecosystems become healthy once again while still allowing us to use fisheries as a resource. Continuing overfishing will put an end to all fisheries because there won’t be any more fish to catch at all. Therefore, the problem overfishing must be taken care of now, or the time to act will be gone

In order for there to be plenty of fish in the years ahead, fisheries will have to develop sustainable fisheries and some will have to close. Due to the constant increase in the human population, the oceans have been overfished with a resulting decline of fish crucial to the economy and communities of the world. The control of the world's fisheries is a controversial subject, as they cannot produce enough to satisfy the demand, especially when there aren't enough fish left to breed in healthy ecosystems. Scientists are often in the role of fisheries managers and must regulate the amount of fishing in the oceans, a position not popular with those who have to make a living fishing ever decreasing populations.
