Shark Population Lab Report

To control the overfishing and growing industrial fishing market, in 1977 the Canadian Government introduced a 200 mile management zone but by that time most of the ecological damage had started. However, during this time other industries like resource-extraction failed, which put pressure on the fishing industry and even the government had to encourage more catching of fish for exports. However, as stocks of cod fish continued to drastically decline the government finally decided to ban cod fishing in 1992. Though the cod fishing industry boosted the Canadian economy and provided employment for local

As they usually hunt old, weak or sick prey, they help to keep the prey population in good condition, healthy and strong, enabling these more naturally fit animals to reproduce and pass on their genes. The effects of removing sharks from ocean ecosystems, although complex and rather unpredictable, are very likely to be ecologically and economically damaging. Here are some reason why killing sharks is very bad: 1)Sharks are being fished at a rate faster than they can recover. Due to overexploitation and lack of proper management, many shark species are under considerable risk of unrecoverable decline with some species having declined to near extinction in recent years. According to reports, sharks are being killed at an alarming rate of up to 273 million worldwide per year.

There is a huge problem with finning for shark steaks or shark fin soup. Because of this, some shark species have dropped by 90 to 50 percent (Choi). In the 80s commercial fisheries made the population of sharks go down even further. Approximately 20 to 100 million sharks are killed each year due to fishing (lovgren). This has caused the total shark population to drop 30 to 50 percent

The Reflection Paper on the “Sharkwater” The Sharkwater is a documentary created by Rob Stewart in 2006. The movie raises an important question about the survival of sharks, one of the most ancient creatures on the planet. It makes people look on these creatures from different point of view. I cannot say I treated sharks only like monstrous characters from films like Jaws or Sharknado before I saw this documentary. But it made to think more about the fate of these animals.

Sea World did not get rid of Tillicum knowing that workers could die, but they wanted to wait until the whale died. At the age of 36 years old all of the trainers went on a boat to see the whales because they are so friendly until they get irritated. Why are people coming to SeaWorld even if trainers are getting killed because it shows how many people like animals. The other whales beat up Tillicum maybe that is why he started killing. Sea World lies to the people they say that they die at the age of 30 years old but really they die about the age of human life spend.

Sometimes, the sharks will hunt in groups. Bull sharks are territorial and is likely the cause for human attacks. When encountering a bull shark, you will most likely see a remora attached. Bull sharks are near threatened. Did you know that the possibly oldest shark may never be completely known?

A number of threatened and endangered bird species have also been found in the digestive tracts of pythons, prompting concern that they could drive some species toward extinction Lampreys in the Great Lake parasitize native fish. Because the native species have not evolved defenses to lampreys, they often die outright from wounds, or wounds become infected and eventually cause

Imagine being in Japan at the ocean on a beautiful spring day. You see all the wonderful creatures popping up from the water. Suddenly, you hear horrible cries of a harmless whale, being slaughtered and exploited by whale hunters. Take a moment and think about what that whale may be feeling. Think about why the hunters are harming it.

The effects of an El Niño can be sensed all over the globe for over a year. The last El Niño to have occurred was in the summers of 1997-98 and it resulted in a colossal decrease of young fur seals. The reason for the loss of the young seals is, that the adult seals will eat before the young ones due to the small amount of food and starvation usually has the biggest impact in the loss of the young seals. As long as the El Niño keeps occurring the population of the Galapagos fur seals will most likely continue to

In 2013, Gabriela Cowperthwaite directed the documentary Blackfish. This documentary is about Tilikum, an orca from SeaWorld that has taken the lives of many trainers. The documentary makes the claim that orcas should be freed from captivity. While in captivity they are causing harm to both themselves, humans, and the other orcas. Blackfish is a great example of an argument that can be rhetorically analyzed because it has pathos, ethos, and logos.
