Colonized around the premises of Australia and eastern Japan, the Knifetooth Sawfish are considered to be an endangered Indo-West Pacific specie (iucnredlist.org, 2013). The Knifetooth Sawfish is an extravagant marine specie in that it has qualities that resemble an unusual type of a Ray for a variety of reasons. First, the Knifetooth Sawfish appears to have a saw like beak, which typically fosters sixteen to twenty nine eloquently sharp teeth (arkive.org, 2012). The Sawfish appears to have an overall fading grey body with remotely small pointed fins (Cielocha, 2014). Another thing about this specie is that it dwells usually in offshore depths that go up to one hundred meters (iucnredlist.org, 2013), and feeds off of small invertebrates such as crabs, shrimps, and squids (arkive.org 2012). Based upon extensive research, not much else is known about the diet of the Knifetooth Sawfish. Therefore, it can be reassuringly regarded as a picky eater if …show more content…
In 2007, the Convention on International Trade in Endangered Species banned international trade on Knifetooth Sawfish, which would help protect the lives of many populations (arkive.org, 2012). Also, the Knifetooth Sawfish is legally protected in India, and Australia is closely researching plans to help preserve the habitats of these sawfish (arkive.org, 2012). Research alone is important because in turn the governing body of that region is at least searching for the best possible solution for the long term. Without these steps, the Knifetooth Sawfish may well be gone at any rate. Despite humanity's ignorance to avoid the situation at all, at least it is still possible to amend the situation. The Convention on International Trade in Endangered Species is doing its best to express the importance of sustaining the Knifetooth Sawfish to an extent (arkive.org,
The nonnative species of the lionfish, living in tropical waters to depths far below is an unseen threat by first glance. Truth behold, this fish is a serious pest since the first sighting in Dania Beach back in the 1980s. Presently, it has grown out of its bounds and causes harm not only to the sea life but trouble to humans as well. An unmatched appetite with a fast and large reproduction to spawn its species in a matter of only a short time, makes this invasive fish at the top of a sounding alarm. Clever biological adaptations have made this fish a tough fighter to the ecosystem and only in the past few years have we learned to take effective measures to control their population to save our coral reefs.
...e use of FAD-associated purse seine caught tuna and will only sell tuna caught using environmentally responsible methods, currently defined to include pole & line and un-associated purse seine.” (JW). Some other conservation groups include the Inter-American Tropical Tuna Commission who works with the Government of member nations in the group to examine the human effects on tuna population and give recommendations on the amount that should be caught to keep a sustained population. WWF is another large group who collaborate with numerous other groups to help the population. Two such collaborations are with the Marine Stewardship Council (MSC) who work by certifying tuna fisheries, and encouraging retailers to buy from MSC certified fisheries and the International Seafood Sustainability Foundation who help in the conservation and management of tuna populations (WWF).
...s to remove the selfish entertainment from nature and focus instead on its intrinsic value. This in situ approach to conservation of cod, although seemingly surface level transcends the boundaries of economic, cultural, or any of such approximations and places the value on the existence of the species. Another projected solution for the crisis of the overexploitation of fish is the institution of moratoria, which establish that a certain species can no longer be hunted or fished in this context. This in situ attempt at regulating the consumption of cod allows the cod for time to replenish themselves and their populations. Yet, this type of regulation suggests that all humankind must do is step back and let for the problem to take care of itself, and as has been proven several times before stepping back and letting things resolve themselves do not end accordingly
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
Scorpaenidae are mostly marine fish,very few found in fresh and brackish water. The family have around around 45 different genera and 380 different species. They are mostly found in the India Ocean and the Pacific Ocean. Most of them lives in coral, tropical reefs and shallow waters, warmer areas. Not all of the family fish lives in the shallow water, small portion of the Scorpaenidae live deep as around 7,000 feet. Just like most of the coral reef fish are, Scorpaenidae have camouflaged body. Their characteristic reflects their name, they have sharp spine that can sting other organisms. Their spine are covered with venomous mucus just like how some other kind of fish are covered with the venomous mucus. Their body are covered with scales. Generally speaking, the Scorpaenidae family fish have different number of spines over the course of the body. Most known type pf Scorpaenidae are lionfish and scorpionfish. Lionfish have preorbital bone with 3 spines, spines and third below the diagonal; , big mouth, end position, oblique fissure. Mandible, vomer and jaw bone with villiform teeth group. Gill openings are wide, tetrabranchiate membranes without the isthmus, pre-opercular margin with 5 spines. Body are ctenoid scales, round head. On the side, there are about eight to nine dorsal fin, fin spines and rays of an anal fin; five to six pectoral fins, they are large, round, and are branched from the upper fin rays. There are about one to five pelvic, sub thoracic; caudal fin rounded truncate. Reef stonefish are extremely camouflaged, they could look exactly like a rock when hiding for predation. The spines of Scorpaenidae are hard and rough, some of their fin spines have poison, can cause serious pain, swells and fatal wounds. Some of ...
Lionfish are not currently listed as threatened in their native range. However, the increase in pollution in coral reefs can negatively affect the lionfish's primary food sources (NOAA, 2011). If lionfish are unable to adapt to declines in their prey species, their numbers will decrease. Although between the increasing reef pollution and the Lionfish’s voracious appetite reef populations will more than likely be damaged beyond repair, they may even be close to elimination by the time the Lionfish population actually declines (Albins, 2013).
A documentary is an informative film that aims to position readers to accept one version of the events or topics expressed. All documentaries posses the ability biased and present an altered version of reality to persuade audience positioning. ‘Blackfish’ is a captivating and inspired documentary released in 2013 concerning the inhumane captivity and domestication of Orcas at SeaWorld for pecuniary advantage. The film, directed by Gabriella Cowperthwaite positions viewers to adopt a dominant reading position on the topic of whale subjugation. The documentary utilises techniques such as expert verification, emotive language and the humanisation of whales to position dominant viewers to accept the ideology that captivity is deleterious
In The Rainbow Fish by Marcus Pfister tells how a beautiful, extraordinary, yet, self-centered blue fish learns that being beautiful isn’t the key to happiness. The blue fish came to find this lesson when he lost his friends. Pfister takes a simple ocean setting and explores the consequences of an individual’s arrogance toward their peers, the process of humbling of oneself, and the tremendous reward one feels when they learn to share. The story achieves these morals by the author’s use of detailed imager and also, the influence of minor characters on the antihero in order to reveal to the audience the true thematic message; selfish actions bring true happiness.
...in suggests, mutual coercion must be applied. Enforced government regulation of the fisheries can achieve this, and extend the restoration of endangered species of fish.
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
Since nearly the beginning of human history fishing has been an integral part of the culture and survival of coastal communities. These coastal communities and cities have always been some of the most prosperous and successful because of the added resource of the ocean. In the beginning many areas were so densely populated with fish and shellfish that often a day’s worth of food could be caught by simply wading into the shallows. For example, some of the first English settlers to see the Chesapeake Bay described “The abundance of oysters is incredible. There are whole banks of them so that the ships must avoid them. . . . They surpass those in England by far in size, indeed, they are four times as large. I often cut them in two, before I could put them into my mouth” (Miller). This abundance had every appearance of being as infinite as the ocean that produced it but the reality was far different. Many fish stocks, including the oyster, stayed near these high levels even into the beginning of the industrial era. However the new rapid pace of technological advancement proved too much for many stocks to handle. Close shore stocks took most damage as they were the easiest to exploit. Those same oyster colonies that were once an obstacle for boats were nearly eradicated by “the 1890s harvests began to decline. Many oyster beds were destroyed and reefs had been mined away. By the 1920s, the boom was over…” (Miller). While catastrophes like this inspired many sustainable practices there are still fisheries worldwide that are headed for a similar end. Through ignorance and misinformation from the fishing industry most of the general public does not know that this is occurring. The following will serve to inform about the t...
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.
...d the economic, ethical, and practical aspects of international regulation. Different views of ecology, culture, and legitimacy as they pertain to a valued resource and its exploitation for human purposes. While it is safe to say one must preserve the historical and cultural value of whaling nations and nations around the world, it can also be said of animals. While many nations continue to cling to their cultural ancestry background of whaling and the right for scientific research, it is proven that such human endeavors must be carefully and faithfully regulated. Commercial whaling has essentially seized to exist in the clear claims of such, but Japan and other nations are ever so slightly getting closer to that boundary. “We should remember in our dealings with animals that they are a sacred trust to us…[They] cannot speak for themselves” (Harriet Beecher Stowe).
There’s No Real Good Guy In the movie, “Blackfish” we are exposed to the fact that the way orcas are treated at SeaWorld is worse than we are lead to believe. We see how they are forced to swim in tiny pools and how they can only be fed if they preform well. After seeing this it makes you feel like the only way to help these poor creatures is to jump on the animal activist wagon and to free all the whales like in “Free Willy”. But is that really the right way to go?
One particularly interesting sea creature is the whale shark, formally known as Rhincondon typus it was first discovered in 1828 by Andrew Smith (Rowat 2012). This large fish is found globally in warm tropical oceans and prefers to stay within 200 meters of the ocean’s surface in waters ranging from 4.2 to 28.7 degrees Celsius (Stevens 2006). This creature can be found all across the globe in any warm tropical seas. Aggregations of whale sharks have been seen off the coast of Australia at times, although it is primarily a creature of solitude. Whale sharks are filter feeders that consume plankton as well as small fish and are harmless to humans. The whale shark is a species with a fascinating ecology, life history, behavior, anatomy
