Shark Population Lab Report

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.

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.

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.

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? There are shark-like scales dated from 455 million years ago, but there is a debate on whether they are truly shark scales.

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 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.
