time. Wild salmon is normally travelling between fresh water to ocean water. But Sea lice could not stand on fish when the salmon travelling in fresh water and this is a natural way to remove sea lice from fish. Though in ocean, farm salmon continuous captive in cages and cannot access to fresh water and this increase of getting more sea lice. European Food Safety Authority (EFSA) mentioned that, “Sea lice is known as biggest welfare and economical risk for salmon at farms in the marine environment” (Algers et al., 2008).

One of the deadliest virus mostly found on Atlantics salmon farms in Canada, Norway, Scotland and Chile is called Infectious Salmon Anaemia Virus (ISA). This disease is not only causing mortality in farm salmon, but also in wild salmon. A well known documentary called “ Salmon Confidential” is available. It's interesting to see that how government cover up this deadest virus causing huge numbers of mortality in wild salmon of BC’s (British Columbia). According to this documentary, wild salmon were suddenly died with huge number along with farm salmon, but Government never confirmed the presence of Euorpean Salmon Viruses those were the causative agents. When biologist Alexandra Morton investigates and finds the presence of dangerous Salomn virus (ISA) and then chain of events occurred by the Government to suppress the findings. This is a good ethical example to explain. Alexandra Morton found the pieces of the virus that was similar to European strain ISA virus. But on the other side, Dr. Gary Marty, who is a BC farm salmon veterinarian said ISA virus never been ruled out in BC. But according to him virus was not cultured alive. It is hard to culture this virus outside the fish if dead fish found after long
