Factors Affecting Marine Fisheries Of Fish Naivete From A No Take Marine Protected Area

The author of American Catch, Paul Greenberg starts us on a journey through america's seafood industry from the early days of abundant seafood to the present condition of our fisheries. America has about 94,000 miles of coast and about 3.5 million miles of rivers, but about 91 percent of our seafood is imported. Here in America 39 percent of citizens call themselves coastal folk, but Greenberg argues we have lost touch with the complex ecosystems of the nation’s shorelines. Estuaries and salt marshes are strange crossroads where salt and freshwater currents meet to be home for oysters, shrimp, and crab. They are also home of dozens of varieties of fish. Greenberg complains about our nation’s destructive relationship with its own shoreline and tells Americans they must desire to “build a bridge back from the plate back to the estuary. This requires us to not just to eat local seafood. It requires the establishment of a working relationship with salt marshes, oyster beds, the natural flow of water from river to sea, and the integrity of the ocean floor.”.

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

It is our duty as humans to ensure the vitality of biodiversity in the world around us, because without biodiversity we could not survive. One of the main problems seen today is the loss of biodiversity in our oceans. Pavan Sukhdev of the UN Environmental Program was quoted as saying "We are in the situation where 40 years down the line we, effectively, are out of fish." (Save our Seas, 2014) Although this quote is both powerful and grim, this is only a future we could meet if we were to continue the mass commercial fishing of stock fish. An essential cornerstone to securing biodiversity, species protection is of the utmost importance when it comes to environmental issues. In the Pacific Northwest there are few species

Iconic Cape Cod Massachusetts is named after the Atlantic Cod. For centuries, this fish has provided food and trade for New Englanders. In this time, there have been several instances of overfishing by humans from the aboriginal era to colonial times but none so drastic as the present conditions of cod fisheries (Jackson, Kirby, Berger, and Bjorndal, 2001). Overfishing is a human induced occurrence where humans are fishing more than a body of water can sustain. In other words, humans are catching more adult fish preventing the existing population from growing to replenish the fish that were caught (Overfishing: A Global Disaster, n.d.). Worldwide, over 80% of the fish stocks are “fully- to over-exploited, depleted, or in a state of collapse” (Overfishing: A Global Disaster, n.d.). The results of this careless behavior has reduced the biodiversity in the Gulf of Maine and landed the Atlantic Cod on the endangered species list as being “vulnerable” (Cod, n.d.). In the neighboring region of Newfoundland, Canada, communities are already feeling the effects of overfishing. In 1992, at the beginning of the fishing season in the Grand Bank region, there were suddenly no more cod. The local economies collapsed and to this day, the region has not quite recovered (Brennan and Withgott, 2005).

The earliest accounts of overfishing occurred in the 1800s, when the demand of whale blubber nearly wiped out the whale populations. In the mid 1900s, the harvesting of Atlantic cod, herring, and California sardines drove them to the brink of extinction. These high disruptions cause regional depletions of animal resources which is starting to cause a global problem. There has never been a more urgent time for fishing nations to make a commitment towards the sustainability of our oceans. More than 80% of the world’s fisheries have been, or are being pushed beyond their limits and are in dire need of strict management plans. Populations of fish and elasmobranch fish such as tuna, grouper and sharks have been declining to the point where the survival

Numerous research and scientific studies were performed on the impact of the extensive fishing along the U.S. coastline. In 1871, National Marine Fisheries Service was launched. Their mission as stated on their website, www.nefsc.noaa.gov/history/, “…devoted to the protection, study, management, and restoration of fish.” (www.nefc.noaa.gov, 2004) While the organization contributed significantly to the study of the fish and the region, the organization was completely ineffectual in any manner in protecting the fish from over fishing and unable to get passed any effective policies to control fishing. Their biocentric view allowed the organization to study fish in a manner that many groups at the time had no concern with due to the mindset of the endless capacity of the sea. The value of many of these studies while questionable at the seriousness at the time they were taken, when looking back through the history and learning from the impact that man has on our environment. In particular, this example there is good data that supports the early thoughts of a bountiful sea of fish. As the years, progress data that clearly shows the decline of various fish species as fishing continues onward. Newton, Dillingham and Choly reported (2006), “The take of Atlantic cod, crucial to the New England economy, had peaked in 1968 at 3.9 million tons; by 1992, it was down to 1.2 million tons— a

The earth’s oceans are overfished. Nearly 80 percent of commercial fisheries are overexploited and some experts believe that global fisheries will completely collapse by 2048 (Barkin page 1). While these are just facts that tell the worst-case scenario, they should be alarms that spark change in the way we fish. This paper, however, will specifically target overfishing in the Grand Banks in Newfoundland, Canada, and analyze its impact on Earth, its Environment and Humanity. Over fishing is simply when fishermen catch more fish than are being reproduced. Eventually the stock of fish in the environment will be completely depleted. That is exactly what happened off the shores of Newfoundland in 1992. With Cod fishing at an all time high, the Canadian government discovered that the Cod population was almost exhausted. New technology and poor decision-making led to the complete destruction of the cod population in the Grand Banks and this is a mistake that we should never repeat.

The Atlantic cod fishery collapse left terrible ecological consequences. As mentioned above, the fishing technology was a major destruction to the ecological system by using deployment and draggers. The huge nets that were dropped and dragged along the bottom of the ocean destroyed the underlying eco-system in the process. The effect of selective fishing on spawning grounds – that is, selectively over-exploiting one species in an ecosystem – had disastrous effect on the feeding relationships in that ecosystem. This contributes to the overall reduction of spawning stock biomass of the targeted species, but also an increase in the number of invertebrate and vertebrate predators such as crustacean and fish which will prey on cod eggs, larvae, and younger fish. It is a little wonder that a species like cod, would eventually run into difficulties struggling to survive when its habitat is being continuously destroyed and the balance of their food chain had been wiped out.

Commercial fishing has a great affect on the marine life for many reasons. Those reasons include species of marine life going extinct, or over population. Some marine life are going extinct from overfishing because as scientists said fish are able to produce only a limited quantity of fish over time this problem cannot only affect the fish but it can affect the entire ecosystem in the ocean. Some species of fish are also going extinct from bycatch. Bycatch is when other species of fish or marine life is captured in the nets with the target fish that is supposed to be caught. It is estimated by scientists that 25 percent of the commercial fishing industries around the world harvest is discarded bycatch. Some species of marine life cannot only go extinct but it can also overpopulate. Certain types of marine life can go extinct because their predators are going also going extinct. This issue arose in the early 1900s when commercial fishing industries expanded their fishing fleets.

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.

Abstract: Overfishing is the process of fishing to the point where more fish are caught than the population can replace through natural reproduction. It may seem profitable to quickly grab as much fish as you can, but it is extremely harmful to the marine ecosystem. The results of this have lasting impacts on the balance of life in the oceans, and the social and economic well-being of the coastal communities who depend on fish for their way of life. Fortunately, there are efforts being done to help prevent this dangerous activity. New Zealand has noticeably led the charge to ending overfishing. Some ways countries have been limiting fishing activities are: marine protected areas, and fishing quotas. These are more of the notable examples,

This issue of overfishing covers vast fields, such as science, humanity, economy, society and nature. The term “optimum”, in regard to the yield from a fishery, is difficult to be defined, precisely and fixedly. Generally speaking, we can describe it as follows: (Niles E. Stople, January 2009, FishNet USA)

When fish like salmon are farmed, often the fish are still kept in the ocean; however, they live inside of nets so that they are still contained. There are many ethical arguments based around these net systems because these nets pose threats to wild salmon. Captive salmon can escape from the nets, which allows them to breed with wild salmon. This can disrupt the natural gene pool of wild salmon. Farmed salmon have been shown to outgrow wild salmon when introduced into the wild, and typically have higher mortality rates, which would be poor traits to be introduced into the wild gene pool, (Hindar, et al., 2006). Unfortunately, with the invasive farmed salmon being introduced to wild populations from escapees of net systems, the recovery of the original wild salmon is unlikely, even if decades went by without more intrusive farmed salmon being present, (Hindar, et al., 2006). Another problem is that the nets do not contain wastes from the captive salmon inside, wastes such as uneaten feed, and feces from the fish are dispersed into the open waters of the ocean. Wild salmon can contract infections and parasites from captive farmed salmon in nets. A study indicated that these parasites, such as sea lice, and infections lead to high mortality rates in wild salmon passing near

Many breeds of fish are being captured at a faster rate than they can reproduce. Some species such as orange roughy fishing became popular in New Zealand in the 1970’s. Over time, it spread to many countries around the world. In the last 20 years, there has been a decline in catch up to 75%. It is no longer common to see in grocery stores as well as restaurants. The amounts of fish that are captured and distributed around the world are alarming opposed to the rate the fish can multiply.

According to the United Nations, 17% of fish stocks worldwide are currently overexploited; 52% are fully exploited; and 7% are depleted. This means that only an estimated 20% of worldwide fish stocks are not already at or above their capacity(Seafarms, 2013). Catches of Pacific herring have decreased by 71% since the 1960s, with Atlantic herring catches falling by 63%. Atlantic Cod catches have fallen by 69% in the same time(Seafarms, 2013). These are just a few of many facts and statistics on the topic of overfishing. The effects of these statistics and facts impact people’s and animal's lives around the
