This is a pod of Killer Whales roaming the ocean. These magnificent creatures can be found in any ocean around the world. Unfortunately these beautiful animals are experiencing some hardships right now.
This is a Chinook Salmon and is located in the northern half of the Pacific ocean and is the main source of food for the killer whale population that lives there. Not only is the Chinook salmon a big source of food for Killer Whales, but apparently also is a big source for the human population. This type of salmon is being over fished and because of this the Killer Whale population is beginning to decrease in population.
This bar graph clearly hows how the Chinook salmon population has been decreasing since 1984 partly due to them being over fished,
This pie graph demonstrates the diet of a southern resident Killer Whale. As you can see the Chinook Salmon is a huge part of the Whale's diet. Without that 82% most of the whales in that part of the sea would starve themselves.
2016 has not been a good year for the Southern Resdient Killer Whale population. This population of Killer Whales only eat salmon, but are sadly running out of food due to the overfishing of the Chinook salmon. This means that the Killer Whales are starving and their population beginning to slowly decrease.
Washington state officials have proposed a new plan to save the Pacific Northwest's endangered Orca population. Their idea is to boost salmon hatchery production by 10 million to 20 million and hopefully this will give them enough food.
The Chinook salmon is one of the biggest fish in the North West region of the Pacific Ocean and in the past 20-30 years the population has been slowly decreasing due to over fishing. Because of this the Orca Whale population does not have enough food to eat. This website shows that less fish are returning from the ocean which means they are producing less and therefor having a huge negative impact on the salmon’s population and this I s mainly due to overfishing.
Not only are these Orcas starving to death, but the stress about to getting food is also decreasing the population. Studies show that since there is a low amount of salmon due to overfishing, that Orca Whales pregnancies are failing due to the whales stressing about finding food. This site shows how scientist looked at the feces at these animals to find out that this is true.
This is a petition to help get rid of some of the dams in the northwest part of the country. This will lead to all the salmon eventually migrating to the ocean which will give the Orcas more food to eat.
All in all we need to need to limit the amount of Chinook Salmon we catch, farm more to release into the wild, etc. Us as a Human population need to realize that our choices do not only affect us, but can have a huge impact others.
