Recommended: Declaration of marine parks and their role

METHODS This study is focusing in Australian waters, especially in Queensland waters. Most sightings are occurred in southeast region around Moreton Bay, which is declared as a marine park in 1993 and have covered more than 3000 km2 multiple use marine protected area. This marine park has four large sand islands (Moreton, Bribie, N. Stradbroke, and S. Stradbroke Island), where the majority of sightings in Queensland occurred on its waters. (Chilvers 2005). This paper is reviewing some journals of southern right whale sightings that related with this species description, population, threats and behaviour, focusing on how this species appeared in Queensland waters. In identifying large marine mammals like the southern right whale, several …show more content…

In 1955 there was a report of sighting, and since 1960s the number started growing until 1990s, where the rate reach up to 7% and doubling every 10 year. Recent studies show that population in Australia is estimated around 2000-2500 individuals, where total world individual reaching 15,000 (Bannister 2008; Kenney 2009). From all sighting reports in Queensland waters (Table 1), two of six were reported as a cow-calf appearances (Bribie Island and North Stradbroke Island) . Table 1.

In Moreton Bay, southern right whale habitat is receiving pressure from human population growth, which resulted in habitat degradation. Human activities near and inside marine park produce sewage, chemical,and noise pollution, also from other recreational activities such as fishing and boat strike that largerly contribute to conservation concern. As sightings growing, a continuous studies such as measurement of ecological factors, along with protection and ecological restoration that supports southern right whale habitat is highly recommended since this species shows an unexpected migration pattern and trend of recovering. Moreton Bay Marine Park already provides some management for ecological protection, while still considering some political, social, and economic factors, for example, the spiritual relation between marine mammals and indigenous people. This issue should be upgraded to a specific framework for marine mammals and the main needs for conserving large diversity of the ecosystem must be taken

Imagine, a 22.5 feet long killer whale that weighs 12,000 pounds, slammed and dragged a person in the water who only weighed 125 pounds. The image is gruesome but that’s what happened to SeaWorld trainer Dawn Brancheau. A respected 40 year old who fought hard to stay alive against the largest orca in captivity. Accordingly to witnesses Tili (short for Tilikium), the Orca went wild during the Dine with Shamu Show, then attacked and killed Dawn. The event shocked everyone because Orcas are usually very friendly but Dawn Brancheau was the third victim of Tilikium.

Andre Cole Ricardo Acosta G. English 101 September 22, 2015 Do Killer Whales Actually Belong in Captivity? Ever since wild animals such as Killer Whales have been captured and kept in theme parks and zoos as amusement, there have been issues on whether they should or shouldn’t be kept in captivity. Killer Whales, otherwise commonly referred to as Orcas, have regularly been taken away from the sea at a very young age so they can be trained, raised and kept in theme parks for exhibition. Although theme parks no longer capture whales from the wild, they are still bred in captivity for public display at marine parks such as Sea World (Gorman).

This film about these extremely diverse mammals shows true footage of the whales and what they are capable of in captivity. It also talks about a lot of wrongs that are done to the whales in captivity by people who were there and done it or witnessed it themselves. The film gives out a lot of good information and statistics that have been proven by others as well. Because this source focuses on captivity and the poor treatment of whales, as will my paper, It will come to great use when the time comes to use

Humans were not around at the time the monk seals arrived, and the monk seals are more commonly found in the Northwestern Hawaiian Islands that are less inhibited by people compared to the Main Hawaiian Islands with a larger human population (Lowry et al, 2011). The Hawaiian monk seal population has been in a rise and fall ever since the discovery of the monk seals by a Russian explorer in 1805. Due to its discovery, the monk seal population virtually died out by the mid 1800’s due to the commercial seal hunting and being killed for food by sailors and whalers (Lowry et al, 2011). Until the mid 1900’s, the seals were never seen and thought to be extinct because they were never seen by hunters or sailors, but the first beach count survey was taken in 1958, showing a slight recovery (Schultz et al, 2010). Another decline was also seen during the 1960’s-1970’s that showed a 75% decrease in number of monk seals seen on the Northwestern Hawaiian Islands (Gilmartin et al,

Everyday all around the world whales are being kept in captivity against their will. Sure, attraction parks such as Sea World are an amazing experience for everyone. Every child wishes to experience large mammals up close doing acrobatics, splashing, and interacting with the trainers. However, whales are not choosing to participate. They are being forced, and rewarded with food, love and attention.

The list is not well rounded and fails to mention sightings of dangerous animals. Brereton states that many deer are seen on the mainland and the islands and there is an abundance of them, predators are mentioned only briefly.

Whaling Through the discovery of the “offshore ground” in the Pacific Ocean, during the 1800s, the whaling industry increased in size and revenue. Many coastal cities such as New Bedford and Nantucket in Massachusetts were well on their way to becoming some of the richest towns in America. However these profits were at the expense of their own men, who left their families for years of arduous labor, resulting in meager pay. Life aboard a whale ship was extremely dangerous due to diseases, starvation, and the act of catching and processing a whale.

However, lack of information on past populations makes it difficult to compare the current recovery in this species, to that of pre-exploitation abundance. Estimates based on genetic diversity suggest they are still only a fraction of their pre-whaling numbers. The purpose of this paper is to examine the humpback whale’s role in the oceans, their populations, and the need for it’s conservation and the manor in which to do

Although the orca can be found in both in the open ocean and in the coastal waters, they primarily inhabit the continental shelf’s in the water less than 200 meters deep. In the cold water area is the most distribution limited by the seasonal pack ice. The killer whale is the top carnivore consumer on the food web. Killer whales may be large in size and appetite, but they still act on instinct and have no desire to kill intentionally. The killer whale is also a very playful and intelligent creature like most dolphins are, therefore they do not deserve the name killer whale.

The separation of non-endangered species will not deter whalers from hunting any whale in sight. These activities are widely documented and filmed for the world to see. Further, “people hunted whales for their oil to fuel lamps and candles, to lubricate machinery and to make margarine, lipsticks and other products.

However, the rate at which the species were discovered became less and less. This correlates with the Species Area Relationship (SAR) theory as proposed by Arrhenius. When graphed, in both plots we notice a curve. This to correlates within the SAR theory in a small area. As we did not analyze a large area, which encompassed multiple biomes, we did not find the “s” shape graph, which is evident in figure 1 in the literature review.

Whaling has become a major issue in recent years. We have seen an increase in this practice, which involves the killing of whales for commercial use. The number one country in whaling is Japan. Japan leads all countries in this act of brutality towards whales. Whaling in Japan is not done specifically for an economic purpose nor to feed citizens, as Japan claims (Wingfield-Hayes, 2016).

Introduction Whale hunting in Japan has become an increasingly controversial topic after the International Whaling Commission law was passed because Japan has been killing large number of whales for scientific research. This is because of that some of whales’ species such as blue whales are considered endangered and this might cause an ecological damage to the sea environment. Whales are intelligent animals and their existence participate in the environmental equilibrium therefore killings whales should be prohibited so as the preserve the environment and ensure the sustainability of our planet. In fact, it morally wrong to kill and eat intelligent animal and to keep hunting large number while is about to extinct. Therefore, Japan

For as long as I can remember I have known what I wanted to do with my life. Science has always been a passion of mine, and medicine in particular has interested me for some time. Dedicating my life to improving the lives of others is very appealing to me. One day I want to join Doctors Without Borders which is an organization that gives aid to war-torn countries. I have worked very hard throughout my student life to get close to achieving that goal.
