What Are Anthropogenic Factors Affect The Right Whale Population Growth?
Due to the small population size of North Atlantic right whales (~300 plus or minus 10%) and the low annual reproductive rate of about every five years, suggests that anthropogenic activities affecting mortality may be more prevalent for right whale population growth than for any other whale species. Ship strikes and fishing gear entanglements are considered the main factors contributing to reduced growth and recovery of the right whale population. Data collected from 1970 through 1999 indicates that the anthropogenic activities (ship strikes and gear entanglements) is responsible for at least two-thirds of the confirmed and possible mortality of non-neonate right whales. The data indicates that there were approximately 45 right whale mortalities

    Killer Whales Rhetorical Analysis

    With such deliberate placement, the writer seeks to exemplify insight of the article by providing historically iconic dates in cetacean captivity, particularly those which have made an impact in media coverage of the topic. By searching through news articles of these dates, the student is immediately able to locate cover stories and breaking news videos of various attacks. Along with dates, statistics can also be found within the entry. Several times throughout the pages, the whale Tilikum appears in association with three deaths in the past years he has been held in captivity, and his being the largest whale in captivity. This means that Tilikum has a violent past, and can easily overcome a trainer. Another statistical factor that is referenced is that of Mean Duration of Captivity, or MDC. “Based upon the MMIR data, and represented in Appendix A, we have calculated the mean duration of captivity (MDC) to be less than nine years. This is regardless of whether an orca was extracted from the ocean, or born at a theme park.” This statement emphasizes that orcas live shockingly short lives while held in captivity, due to less-than-ideal living conditions. The statistics provide the student with a grasp of exactly of much or how many ways the actions of the parks have an effect on the animals living in captivity. It provides concrete evidence on which we can rely for an image of things such…

    Killer Whales Research

    This Killer Whale, Keiko, was born in the wild and captured around the age of two. He was then sold and transferred from Iceland to an amusement park in Mexico, where he lived in a single pool without contact with any other Orcas from 1985 to 1996. The amusement park had a few bottle nosed dolphins in the same program, but for the most part Keiko was alone. Later, Keiko was conditioned to follow a boat and was taken out regularly to do open ocean swims as a part of a research study. During these swims, Keiko was in proximity of other local Killer Whales and eventually his human interaction was limited over the course of a few months. Initially, Keiko’s interaction with the wild Orcas was partial. He and the pod generally moved away from one another. After a few open ocean swims and being taken directly toward the pod, Keiko began to follow the pod within a local vicinity. The pod seemed to tolerate his presence and thus Keiko began to travel with the group. However, after Keiko’s release back into the wild, researchers studied how often Keiko approached the boat. The group reported that he approached the boat roughly sixteen times, this was with minimal interaction on the researchers’ part. (Simon) Moreover, after captivity and immense amounts of human captivity and no social interaction with other Killer Whales for a period of eleven years, releasing Keiko into the wild showed extreme behavioral differences from other wild Orcas in the area. Since the social construct of a pod of Kill Whales is extremely strong, often times outsider whales are left to swim at a certain distance from the pod. Observations were made of Keiko swimming in the vicinity of the group, but there were no observations or research made that showed Keiko apart of the social…

    Killer Whale, largest member of the dolphin family. Killer whales occur in more parts of the world than probably any other cetacean (see Whale). They occur in all oceans, both in the open ocean and close to shore, but are more common in the colder, more productive waters of both hemispheres than in the Tropics. Resident populations may cover an area of several hundred square kilometers. Transient populations often move through an area rapidly, swimming more than 1000 km (more than 600 mi) along a shoreline in a matter of days. Killer whales are black or deep brown overall, with striking white patches above the eye and from the lower jaw to the belly, and a fainter grayish-white saddle patch just under and behind the dorsal fin. Males are somewhat…

    Why Do Killer Whales In Captivity?

    Killer whales in captivity should be let back into the wild, because the whales have echolocation, they are causing harm to the humans taking care of them, and they are spacing issues at the capturing centers. These are just some of the important reasons why killer whales in captivity should be released. Presently, echolocation is how orca’s find their food, and navigate through the ocean. The orca’s make a sound and the sounds are reflected of off different objects in the ocean, then the orca will know where he or she is and if there is food nearby.…

    Why Should Whales Be In Captivity?

    I do not think whales should be in captivity because whales are way too big to be in takes at seaworld the whales can’t even move around in the tank, imagine you are living in the entire ocean and then you just get pulled out and get put in a tank where you can’t even move. I think that they just want a bigger crowd because it means they would get more money. Whales should not be in captivity because the tanks are way to small, Trainers don't not feed the whale enough, and people don’t have the best interest in the whales.…

    Animal Overpopulation

    Wild animal overpopulation can have some devastating effects on human life. Too much wildlife can hurt economy, make people sick, cause human injury or even death, and ruin vegetation. Hunting has been a way of life since the beginning of time. Native Americans have hunted to feed their tribes and rituals of children to become men. Dinosaurs used to hunt in order to survive. As for other animals, hunting is their way of life. It was a major part of ancient life and practices are still being used today. To hunt is a very important tool for survival and to maintain control of wild animal overpopulation. If there was ever an outbreak of wild animals like deer and boars would destroy everything in their path.…

    In the Heart of the Sea: Importance of the Whaling Industry in the 19th Century

    In 1819, The whale ship, Essex, set its sails and departed from Nantucket, Massachusetts on a voyage to the Pacific Ocean to hunt and kill sperm whales and retrieve the abundance of oil the whales possess, which became a crucial component in 19th century industry [2]. The island of Nantucket had been one of the most important oil businesses for quite some time. For the crew of the whale ships, harvesting whales was a tough assignment; when a whale was spotted, the crew would approach it, harpoon it, and then try to kill it. Once a whale was killed, its blubber was peeled from the corpse and then boiled for the high quality oil. On this particular journey the crew faced even more difficulties than just the killing of the whales. As sperm whales can reach upwards of sixty tons [1], they had the potential to destroy a whaling boat, as the crew of the Essex unfortunately learned. The whale ship goes through a huge storm, was attacked by a large sperm whale, became shipwrecked and was forced to navigate the sea with limited supplies in very small whaleboats, leading to starvation, dehydration, cannibalism, and even death. The story of the Essex is an important part of history, as it demonstrated not only the importance of the whaling industry upon 19th century citizens, but how such a tragic event played an important role on a community such as Nantucket.…

    Threats Of Humpback Whales

    Humpback whales experience great threats from human interference such as by-catch, oil and gas expansion. They also are experiencing environmental changes that can potentially hurt their breeding and feeding aggregations such as climate change. By studying their feeding ecology we can learn about any trophic level shifts that may have occurred due to these threats and observe their successfulness. Previous studies in other areas, such as the Gulf of Maine and the North Pacific Ocean, classify humpback whales (Megaptera novaeangliae) as generalists-feeding on nekton and plankton species. In the Gulf of Alaska, scientists have observed the humpbacks feeding exclusively on one type of food source at a time, but it is unclear if these whales remain…
