Necropsy

[1][2] These pictures are of vetinarians performing a necropsy on a fish. In the second picture you can see all the tools they are using.

 A necropsy is a post mortem examination that has been used for more than 2,000 years and is either performed for legal or medical purposes. The term autopsy derives from the greek and means "to see oneself". Necropsy also derives from greek and means "seeing a dead body"[3] Necropsy is also known as Autopsy(human). A necropsy can be used on almost any living organism and is always done for the same purpose.[4] Necropsy is also the examination of a cadaver to determine or confirm the cause of death.[5] Their are two types of necropsys that can be performed on a cadaver such as the External examination and the Internal examination.[6] External examination is just to study the outside of the body to find out the cause of death. Internal examination is just to study the inside of an animal to find out the cause of death. Necropsy helps us understand what may have killed the animal. __**How is a Necropsy done?**__ A Necropsy is done by doctors, vets, or any medical specialized people. They make an incision in the stomach of the fish. First they look for any injuries or diseases present in the body. If there are no signs of disease or injury they take out the organs and other body parts and examine those closly. They look for oil, litter, etc. in the ocean, lake or pond that may have killed the fish. [7]
 * __What is necropsy and why is it done? __**

There are some guidelines that should be followed to perform a good necropsy. First, a thorough history of the animal should be gathered before the necropsy is performed. This should include as much information about the animal's life and death as possible. Second, necropsies should be performed as soon after death as possible because the animal's tissues begin to change very quickly. Animals that can't be examined immediately should be refrigerated. Third, protective clothing should be worn to protect the person performing the necropsy. Finally, the person performing the necropsy should have a consistent method for examining the entire animal. [8]  __**Relating to the Gray Bay area**__ Fish are dying in the Gray bay area and no one knows why. 50 fish were examined and there were different fish. Some were carp, trout, salmon and pike. The necropsy results were: 14- oil in stomachs 21- ins. O2 8- chlorine 7- unknown [9]
