The federal government has launched a review after tests showed a contagious fish virus in blood spewing into a B.C. waterway from a fish processing plant.

CTV鈥檚 Melanie Nagy first reported Monday on video footage that shows a pipe gushing effluent into B.C.鈥檚 Discovery Passage, one of Canada鈥檚 largest migratory routes for wild salmon. Each year, millions of fish pass through the region on Vancouver Island鈥檚 east coast.

The video shows a steady column of blood flowing from an open pipe into the ocean at a depth of about 30 metres. The pipe is linked to Brown鈥檚 Bay Packing Co., a farmed Atlantic salmon plant near Campbell River that processes fish for many foreign-owned companies.

But the Discovery Passage pipe isn鈥檛 the only one. B.C. photographer Tavish Campbell, who recorded the video, shot footage of a second pipe pouring blood into the water near Tofino.

The second pipe was connected to another processing plant.

Blood samples from both pipes were collected and tested at the Atlantic Veterinary College. The effluent was found to be infected with

PRV was first found in Canada in 2011. Now, it is estimated to affect up to 80 per cent of B.C.鈥檚 farmed salmon. The virus has been linked to HSMI, a potentially deadly disease that causes heart lesions and organ hemorrhaging in fish.

The disease doesn鈥檛 pose a risk to humans, but can wipe out up to a fifth of a salmon farm population.

Marine researcher Alexandra Morton said continued spread of PRV would have devastating consequences on wild salmon. Salmon populations are considered a vital link in B.C.鈥檚 food chain and are a key food source for species such as orca whales and bears.

鈥淧iscine reovirus is known to be a highly durable virus, so it can last a long time in the water,鈥� said Morton, a longtime critic of salmon farming in B.C.

The federal government said fish plant effluent falls under the provincial government鈥檚 jurisdiction. But Fisheries Minister Dominic LeBlanc was so alarmed by the video that he opted to launch a review.

鈥淥bviously if there鈥檚 an appropriate enforcement action that will take place, it will take place,鈥� LeBlanc said.

The B.C. government confirmed it is also investigating. The province鈥檚 environment minister, George Heyman, said it鈥檚 important to know what鈥檚 entering the water.

鈥淲e want to ensure that anything discharged into the ocean is safe before it hits the water,鈥� Heyman said.

B.C. authorities will also conduct a large-scale audit of fish processing plants to make sure they meet regulatory requirements and that the environment is protected. According to the province, some plants operate on permit standards established decades ago.

The farmed salmon industry insists that it adheres to the highest waste treatments standards. Still, the industry said it will also conduct a review of processes at all fish plants.

Dave Stover, the manager of Brown's Bay Packing, told 麻豆影视 that the company has an 鈥渆ffluent permit鈥� with the province. Stover added that the processing plant follows industry standards.

Steven Hedlund, communications manager with (GAA), an international non-governmental organization that advocates for responsible practices within the aquaculture industry and provides certification for plants, said the GAA鈥檚 standards require plants to 鈥渟creen out solids and treat effluents by chlorination or another method of disinfection which will kill the disease organisms before released.鈥�

He added that certified plants are required to facilitate 鈥減eriodic monitoring鈥� of effluent to ensure that no live organisms or pathogens are present.

Brown鈥檚 Bay Packing Co. is certified by the GAA, Hedlund confirmed.

Michael Price, a biologist who has investigated fish processing plants and highlighted risks, said wild salmon may be under threat due to the industry.

鈥淚t is a constant source of potential pathogens,鈥� Price said. 鈥淭his is the big red flag, I think, for wild salmon conservation.鈥�

Indigenous groups in B.C. have been raising the issue for years. Chief Ernest Alfred, a hereditary chief from the 'Namgis, Lawit'sis and Mamalilikulla nations, launched a protest in August that saw environmentalists and Indigenous activists occupy a fish farm near Alert Bay, B.C.

Alfred said he believes fish farms and processing plants violate human rights by negatively impacting wild salmon, which are a source of livelihood and food for those living along Canada鈥檚 west coast.

鈥淚f we want a functioning ecosystem, we have to do something now,鈥� he said.
