The Birth of Fish; The Death of Oceans
Overview:
Life and death are themselves opposites; then again in our oceans, life sometimes causes death. Over the past few decades, the demand for edible seafood has sky rocketed, resulting in the formation of aquacultures and overfishing. As of now, the two greatest threats to our marine resources result from overfishing and water pollution. Commercial fishing targets key fish species, resulting in an imbalance of the marine ecosystem. In response to the near elimination of these species, an industry has developed to raise these species in farm communities. It was the initial belief of many that aquacultures would help offset the demand for more seafood. However, the result of fish farming has only contributed to the depletion of the fish population and to the pollution of the marine ecosystem.
With only limited regulations placed upon fishing companies, they are basically able to have free range over the oceans. Because of this, there have been severe effects on many fish species. Even with regulations such as the law of the sea, which states that a country bordering the ocean has rights to the fishing areas within two hundred nautical miles of its shores, there are considerable abuses. In Pauly and Watson’s article, it states that the preservation of the country’s fisheries is up to the country itself. The country may also give out rights to other countries to fish its waters. When this occurs, there is a great chance the fleets from other countries will attempt to “garner as much fish as they can” (Pauly, par. 7). These fleets will also have a disregard as far as the preservation of the marine habitat below such as the reefs (Pauly, Counting The Last Fish).

With a coastline of over 202 000 km and over a fourth of the world’s freshwater resources, it is no wonder why Canada’s fishing industry is a huge part of its economy.1 Canada exports more than 75% of its fish to over 130 countries worldwide. Many of the 7 million people who reside on the coast depend on the ocean’s resources. In total, Canada’s entire fishing industry is worth around 5$ billion dollars a year, being one of the world’s most valuable. However, the coasts have not been treated by respect; overfishing, over consumption, and wasteful practices has deteriorated, not only the industry, but the ecosystems and fish populations. This is a huge global issue; the worldwide collapse of fisheries has been project for 2048. Slowly, as the trends continue, we will inevitably see many fish species start to disappear. In fact, the ill-treatment of species on the Canadian border has already devastated a large specie, the cod.

Accoring to “Overfishing of Blue fin Tuna: Incentivizing Inclusive Solutions,” it is estimated that 53% of tuna is exploited, while Blue fin Tuna have shown a significant decrease in the stock of reproductive Blue fin tuna by 80% since 1972 (Boon 1). By these statistics, it is clearly shown how much we take them for granted. Originally, Blue fin tuna were considered an inexhaustible food supply. However, as time has shown that ignorance really is bliss. If we stop and think of alternatives on how to save the Blue fin tuna population, we would be able to preserve the species for later generations to come.
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.
Due to the demand many packaging for the fish can find its was back to sea, or when fishermen are out at sea they can leave their garbage. Many nets from the boats and gears can also be found in the water, that fish can later see as food, eat it, and die; this ties back to extinction in fish. There is much pollution and decline stocks in fish because it is very hard to regulate the seas. To fulfill the growing demand for seafood, many companies are forced to fish beyond areas that are supposed to be non-fishing zones. This is because there are hardly any laws or restrictions telling them where they can and cannot fish. Sally Driscoll and Tom Warhol report in, ‘Overfishing’, that itt wasn’t until 1956 where we saw our first regulation, the United Nations organized the first UN Convention of the Law of the Sea or the NCLOS which helped promote rights of all countries by establishing boundaries off shore. Meaning that some seafood fished in certain areas of the ocean cannot be sold in certain countries, and in some areas it is illegal to fish unless you have a permit from that country. Economy also helps make it harder to regulate the seas, in ‘Overfishing’ it is explained that Preisdent Barack Obama brought up Antiquities Act of 1906, that let fishermen expand their fishing areas. The United Nations FAO estimates that 25 percent of all fish trapped in nets are labeled unusable or not licensed for fishing by the

The Tragedy of the Salmon The United States Pacific Northwest has historically been a significant player in the global fishing industry. However, over the last half-century, the fish population in the area has been declining at an alarming rate. Popular species of fish such as cod and salmon have been particularly susceptible to these decreases. What once was a region flourishing with abundant fish populations, is now in danger of being exploited to the point of extinction of certain species. The majority of these population drops is attributed to increased industrialization and overfishing in the region.
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
In the real world, all this comes down to two serious problems. We are losing species as well as entire ecosystems. As a result, the overall ecological unity of our oceans is under stress and at risk of collapse. The affects the fish that is at the bottom of the food chain to overpopulate. If the fish that are at the bottom of the food chain overpopulate, the food they eat will become scarce This means that the fish that is at the bottom of the food chain will become extinct or endangered because of the lack of food. Another effect of overfishing that is fishing down the food chain. That will affect the species that are at the top of the food chain because the species that are at the bottom of the food is chain are important preys to them. That’s why fishers should be aware, that if they catch too much of the fish that is at the top of the food chain it will affect the whole system of predators and preys. If the fishers catch too much of fish, that’s at the top of the food chain, it would also affect the balance of predators and
To fish or not to fish is a personal choice. The fact that the oceans are being overfished is a growing concern for individuals, organizations, and governments throughout the world. In this paper I want to discuss the effects of overfishing on the restaurant industry, and possible solutions to solve the problem. Fishing is an ongoing source of food for people around the world. In many countries it is a food staple in their everyday diet. In more modern societies eating fish has become a sensual experience, and not just for the wealthy. It hasn't been until population explosions in the last century that the demand for seafood has led to more effective fishing techniques and technologies. Now the demand for popular fish like the salmon, tuna, sea bass, cod and hoki, which is the key fish in McDonalds filet o' fish, is diving wild populations to dangerously low levels. The methods used to catch the amount of fish demanded by the industry do not leave sustainable populations in the wild. In an attempt to preserve the fish population, governments have set limits on the minimum size that may be harvested and how many of each may be taken. Boundaries have been set up saying which areas can be fished and which ones should be left alone. A number of smaller fisheries have gone out of business because of the limits imposed by the government. This leads to even less fish being harvested and brought to market. Therefore the amount and varieties of fish at markets are smaller and can cause shortages for wholesalers and restaurants. Some restaurants will no longer have the variety on their menus that they used to enjoy. If a restaurant thrives on its seafood menu they may be unable to cope with the shortages and will go out of business. In the ...
Fish protein has been a mainstay for the human diet for centuries. However, aquaculture, which is the practice of raising fish such as salmon in controlled conditions, as opposed to the commercial fishing industry, which is procurement of wild fish from their natural environment, made its debut in the United States as a commercial enterprise in the late 1970’s according to the Eco - Justice Marketplace Project.(n.d.). This mode of salmon procurement began to develop in the late eighteenth and early nineteenth century, as a response to the declining populations of native wild fish such as salmon and trout.
Throughout Canada’s economy, many industries factor how Canada makes money such as the mining industry, oil and natural gas industry, forest industry and even the agricultural industry. Although the most quick and deadly decline in an industry occurred the fishing industry. The fishing industry happened along east and west coastal areas where Atlantic cod or salmon were abundantly found while today the population of salmon is almost extinct and the moratorium in NL stands to protect fish in Canada. Today hardly any fish are able to reproduce themselves in the coastal seas where fishes were abundant about 30 years ago. The dramatic collapse of the fish population was of the regarding reasons the use of modern technology, mismanagement of the government and overfishing. To begin, fishing was done on a renewable basis by waiting until the fish were migrating and selected the fish they wanted. However, today both coasts of Canada’s fishery does not exist mainly due to the fact, after the 1950’s the new use of technology such as violent new boats with radar that have a electronic navigation systems and sonar allowed fisherman to follow the fish to their homes even in winter. This caused fisherman to fish year round, day and night, even in ice to the homes of fish. In addition, the use of huge nets also swept up many non-commercial species or commercial fish so young that they should have been left in the ocean to reproduce. In addition, one-third of the fish caught was actually taken to the market to sell while the rest were dumped (killed). The use of technology killed more fishes than any other centuries of fishing. The use of modern technology was not monitored thus killing more fish. With thousands of fish commercial or not the...
Overfishing is a harmful practice, that will eventually lead to the collapse of aquatic ecosystems, if it’s not dealt with promptly. Overfishing emerges from the combination of our over consumptive society mixed with the great profits that come from hauling in a good catch. The consumers demand for fish in Japan seems to be at an increasingly high rate due to the enjoyment and cultural values that arise from sushi and other traditional dishes involving seafood. Approximately 23 percent of Japan’s protein intake comes from the ocean, and as a nation consumes 7.5 million tonnes of seafood annually. CITATION
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...
Did you know that more than 90 percent of all organisms that have ever lived on Earth are extinct? According to Pandey, the author of Humans Pushing Marine Life toward ‘Major Extinction’, nearly 10,000 species go extinct each year, and this rate is estimated to be 1,000 times higher than the natural extinction rate (1). Human beings are causing irreversible damage to the oceans and their wildlife, which is being led by two major reasons: Commercial fishing or over-fishing, which damaged the marine environment and caused a loss in the marine life diversity, and pollution, which is a primary way of the extinction causes that drastically modifies the marine life habitat. As a result of the commercial fishing and pollution, many of the marine species will start disappearing of the oceans. Briggs emphasizes that over-fishing “has induced population collapses in many species. So instead of having less than a hundred species at risk, as was the case some 30-40 years ago, there are now a thousand or more (10).”
