According to world wildlife organisation, overfishing occurs when more fish are caught than the population can replace through natural reproduction. Gathering as many fish as possible may seem like a profitable practice, but overfishing has serious consequences. The results may not only affect the balance of life in the oceans, but also the social and economic well-being of the coastal communities who depend on fish for their way of life.
Andy Dehart, Discovery Channel Shark Advisor, spoke about the North Carolina shark over fishing problem. The shark populations on the East Coast were extremely over-fished which lead to the over population of sting rays, a main food-stock for sharks. The stingrays in turn decimated the shellfish populations on the East Coast, leading to calm and shellfish shortages. This shows that sharks are necessary for every eco-system and their destruction affects us in more ways then we can imagine. Sharks are very at-risk for over-fishing because they take a long time to reach the stage where they can reproduce and in general only have a few pups when they give birth.
Overfishing Overfishing means to deplete or exhaust a stock of fish or shellfish by excessive fishing. This may not seem like a topic that is ever worth argueing over, or worth making laws for, but little do people know that the consequences of overfishing will soon affect the entire world. This will not only affect ocean life, it will also affect humans, as well as all other living organisms lives as well. There are already several overfishing laws existing, but they are easily avoidable and is done so with so many large fishing companies.
Sharks have been swimming the world’s oceans for more than 400 million years - 100 years before the first dinosaurs appeared (Griffin et al., 2008). Sharks fall under the kingdom Animalia, the phylum Chordate and the class chondrichthyes. There are more than 400 known shark species found in the ocean (Musick and Musick, 2011). In the ocean, sharks help maintain the health of ocean ecosystems and help regulate and maintain the balance of the marine environment (Griffin et al., 2008). These sharks have slow growth rates and reach sexual maturity at a relatively late age compared to other marine fish, which leaves their population vulnerable to any outside sources (Musick and Musick, 2011). Sharks have been apex predators in the ocean for millions of years, however, the populations of sharks have been at risk for years as a result of many different factors.
Commercial fishing is defined as the harvesting of wild fish and other seafood for commercial profit, and provides a large quantity of food to many people around the world. In comparison to commercial fishing, aquaculture, also known as aquafarming, is the farming of aquatic organisms and populating them in controlled environments. The aquaculture industry in the United States is primarily dominated by freshwater catfish farming producing more than 1 billion dollars. Although aquaculture seems beneficial, it has many negative impacts on the environment that are threatening the marine ecosystem.
The Atlantic Ocean is the second largest ocean in the world. With an area of about 41.08 million square feet, the Atlantic Ocean covers 20% of the earth’s surface. The Atlantic Ocean is half the size of the Pacific Oceana and animals from Thresher sharks to King Salmon thrive there. King Salmon fish thrive amazing well in the Atlantic Ocean.
About 71 percent of our planet Earth is covered by water, and the majority comes from the oceans (about 96.5 percent of all Earth’s water). It remains as the most expansive, diverse, and mysterious places on planet Earth. But it is being threatened by the pollution by people and nature itself. By polluting the habitat of marine organism will indirectly affect the ecosystem of the marine life. Marine life is dying and as the result the oceanic ecosystem is threatened.
Harmful fishing methods are unnecessarily killing turtles, dolphins, and destroying critical habitats. Global warming is increasing the temperature of the ocean water, reducing the generation of the base of the food web, plankton. The reducing of the plankton generation is causing major marine ecosystem change. Pollution is also a significant environmental issue HAL is facing. More oil reaches the ocean each year, a massive amount of oil has been accidently spilled from ships, which in turn is destroying animal and aquatic plant life.
Imagine a world without any fish in our ocean, nothing for the next generation no ahis mahi mahis ,marlins and many more fish we won’t have if over fish our oceans. I feel that overfishing in Hawaii is a major problem for 3 reasons such as people are taking fish that are under the size limit on the fish, another example is people are taking the fish that are the big breeders and they don’t give them a chance to repopulate and for the last example is people are taking more than they need and it could be a waste because it just sits in the freezer.
Many different theories have been suggested to explain why the East Coast Fishery collapsed. A few examples include overfishing, destructive fishing practices, and changes in natural conditions. Primarily, overfishing plays a huge role in the collapse of the East Coast Fishery. The amount of catch allowed by the federal government was extensively high. Scientists may have overestimated the number of fish reaching adulthood each year, due to this more fish were caught then reached maturity.
Negative Effects of Ocean Pollution “Each day, oil used to lubricate engines and to power the vessel leaks into the ocean” (Wroble 44). When the residue enters the ocean, it begins to affect the environment and animals. This is just one of the many problems from ocean pollution. “According to Worldwatch research associate Peter Weber, 80 to 90 percent of all of the materials dumped at sea are dredgings...
Examples of negative local practices are the usage of poison/explosives and overfishing. Overfishing as the name suggests, is fishing a certain fish to an excess amount, decimating the population. This could put multiple organisms’ populations at risk and populations may possibly go extinct. Another practice that negatively impacts the ocean is the usage of poison and explosives. Obviously, the poison that is used in fishing (mainly cyanide) is harmful for the ocean because it may poison other fish over the years.
When you think of the beach what do you think of? Would you say something along the lines of beautiful blue water, smooth white sand, graceful fish, a breathtaking experience, and much much more? But what if that wasn 't the case. What if all those magnificent things were false due to the reality of oil spills , dying fish, dirty water, and plastic in our oceans. These things really are happening in the world, its called ocean pollution. Because of this marine life is constantly dying, innocent fish are mistaking plastic for food and becoming sick, and eventually all that plastic will kill everything beautiful in the ocean . Ocean pollution does not only kill marine life, but it is also is killing birds and coral reefs. Would you like
The ocean is nowadays undergoing numerous environmental issues that further lead to marine pollution. Marine pollution is a very serious environmental issue that most of the countries of the world encounter. Aquatic littering is considered as one of the major causes of marine environment. The misleading use of the marine environment is extremely impacting the marine life and ecosystems. Moreover, the total amount of toxins and debris discharged by human beings is incredibly increasing in today 's world.
