Adaptive Capacity Case Study

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

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 oceans need to be protected because it is where life began and if not taken care of, life as we know it will end. The well-being of the ocean is constantly being threatened and needs to stop. When dangerous substances go into the ocean, ecosystems suffer and become endangered along with the lives of people and marine life. The importance of protecting and preserving the quality and biodiversity of the world 's coasts must be recognized because they are truly irreplaceable. If humans are not educated , and become careless about what is thrown on the ground or sprayed on lawns, disastrous effects follow when it comes to the condition of the ocean’s ecosystems, which can endanger life itself, leading to a problem only we can correct. There is historical evidence of ocean pollution, although the problem still shadows us today.

On March 21st, our class went to the Monterey Bay Aquarium. The purpose of this trip was not only to explore Earth’s natural habitat’s, but it was also to gather information on our upcoming project and to gather information on how the community of St.Mary, affects the Monterey Bay Aquarium. The answer that we found out is one based off of what we eat. The Monterey Bay Aquarium released an app where it showed which type of seafood were lower in numbers than others. So, if plankton were very low in numbers, it is advised that we not fish for them or not eat as much of it. This shows based just off of what we eat, we can affect the numbers of in the ocean. Also, those plastic bags we buy at Target and Walmart, that we drop outside, drifts itself to the streams, which flow to rivers, which go to oceans, they are floating there, not doing much harm, until sea turtle comes by starts eating it, but gets tangled and choked in it, dies.

Studies have repeatedly shown that as oxygen concentrations decrease, the abundance and diversity of fish decrease (Breitburg). Fish kills, in which large numbers of dead and dying fish float to the surface or wash onto shore, are probably the most dramatic and publicly visible manifestation of hypoxia and nutrient over-enrichment of coastal waters(Breitburg). In addition to mass mortalities that are easily observed, high mortality of fish lacking a swim bladder can occur leaving little or no visible evidence of fish at the surface or littering beaches (Breitburg). With no fish, shrimp, or crabs the Louisiana fishing market takes a huge hit that the economy feels in a major way. The gulf accounts for almost one-fifth of the countries fishing landings, which total to be three billion dollars (Petrolia). Fishing is not only a major part of Louisiana’s economy but also its culture. Without wildlife in our waters microorganism are given more opportunity to grow leading to bacteria infected waters. These bacteria infected waters could cause major health risks for those who come in contact with

Marine pollution is not a new phenomenon, but our acknowledgement of its impacts and severity is relatively new, with the first laws and discussions to counter it only appearing in the 1950’s. For much of history, it was thought that the oceans were so large that any pollution created would be negligible and easily diluted (Marine Pollution). Since, countless research and laws have been implemented in order to preserve our marine ecosystems because of how crucial these ecosystems are to humanity.

As the population on earth increases ,overfishing has become a growing issue in all parts of the world. Fish is a vital food source for many, in the world and counts for many of the cultures and heritages in the world, which means there is a high demand for it . This high demand has caused overfishing to occur. This is a cause for concern since due to the development of better technology, there is a higher risk of overfishing if not managed properly. Canada in particular has been facing the problem overfishing for years now. Due to Canada’s issue of overfishing, the environment and wildlife as well as human settlements all have negative impacts ,therefore a sustainable solution must be implemented. If action isn’t taken, Canada’s issue of overfishing will continue to worsen.

In 2009, Dr. Sylvia Earle wrote The World is Blue to educate and alert the reader about human impacts on marine ecosystems. Through this book she conveys her passion and methodical arguments concerning the importance of the conservation of the ocean, which encompasses approximately 80 percent of the earth’s surface. Dr. Earle states “the ocean touches you with every breath you take, every drop of water you drink, every bite you consume” (17). This statement emphasizes the significance of the ocean, not only for marine life, but all life forms on earth. The book implies that currently in today’s world, the conservation of the ocean requires a global effort to reduce human damage from the past generations. Using facts gleaned from credible scientific resources, she defines the problems of overfishing, bycatch, and pollution. By analyzing human impacts on marine ecosystems, Dr. Earle determines successful and unsuccessful solutions to these problems and suggests various ways individuals can change their lifestyles to reduce impact on the environment as a whole.

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.

In Canada, the Grand Banks habitat is in “environmental degradation” (Connor and Taitano) due to bottom trawlers tearing up the sea floor displacing and destroying the vegetation at the seafloor and therefore disrupting the habitat of the small fish the cod prey upon (Connor and Taitano). Bottom trawls also disrupt the “breeding patterns of the cod.. Damaging fertilized eggs.. And greatly reducing the amount of young born” (Connor and Taitano). In the United States, the Gulf of Maine provides evidence of a loss of the young and old cod due to predation (Connor). Farming atlantic cod, like many fisheries are doing to replenish the atlantic salmon populations, have resulted in a breakout of the disease Yersiniosis (Connor and Taitano).The disease affects the fish’s intestinal tract before spreading throughout its body. The mortality rate with this disease is low, about 5%, however the illness prevents the affected cod from being sold at a market due to health violations (Connor and

Since the beginning of the human race, the ocean has been a major source of food. People near the shores have been taking of advantage of the ocean’s rich and diverse source of nourishment for centuries, both as a source of food and a livelihood. However, since the dawn of the industrial age, humans have begun to take from the ocean more that it can give. As a result, the ocean can no longer provide the human race with the abundance that it once did. As technology rapidly advances, populations skyrocket, and global warming spreads havoc, the ocean’s biodiversity and once abundant supply of fish is dwindling, calling marine scientists and experts to race to find solutions that will restore the oceans health while battling world hunger.

The main causes of overfishing are poor fishery management with a lack of regulation, unrestricted access to the ocean and illegal fishing. During the last few decades the demand for edible seafood globally has skyrocketed and the high demand is causing us to overfish to keep up with the demand. Unfortunately, fisherman are catching more fish than can be naturally reproduced. There are only limited regulations in place, which means that fishing companies are basically fishing when and where they want to with out any oversite. Overfishing causes such serious effects such as the ocean life getting knocked out of balance. Coastal communities rely on the benefits of the fishing for social and economic health. When we overfish it

The world we live in is so vast and exciting. Seventy percent of our world is liquid water we call the ocean. In the ocean there are many creatures that each are unique in their own way. However, it is possible that in our lifetime, many marine organisms will become endangered or possibly extinct. The loss of these mejestic marine creatures will be caused mainly because of human advancements in which fossil fuels are used to produce energy. Biodiversity is greatly affected by this increase in acidity. As the ocean acidifies, multiple social and economic issues arise. As humans, we rely on the ocean for almost everything. Much of our food, clothing, cleaning products and cosmetics come from the ocean. With the loss of

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
