Scary scene! Submarine water pipes gush blood, triggering Canadian ecological crisis

When a Canadian photographer Tavish Campbell dived in 2017, he found a sewage pipe that was constantly emitting red liquid on the bottom of the sea. After a follow-up investigation, it was found that the local processing plant illegally discharged salmon waste blood. He immediately responded to the local government at that time, but two years later, Campbell shared a video of the dive on Tuesday (3) via Facebook, and found that the situation had not improved, and the pipe was still spewing a lot of blood. Campbell said in a video post that the blood was tested and confirmed to contain PRV virus, which can cause inflammation, jaundice, and organ failure of fish heart and skeletal muscles, and eventually cause fish death. It is also one of the causes of death of a large number of wild salmon. The 2010 report in Europe showed that the virus might originate from British Columbia, Canada, where Campbell dives. According to statistics in this report, the virus originally only existed in farmed salmon, most likely because the salmon processing plant illegally discharged waste blood, causing the epidemic to spread. More than 80% of salmon in BC are infected with the bacterium, spreading the virus to the Atlantic, Europe and other places through salmon meat, salmon eggs export, and waste blood pollution. According to a report by a Canadian fishery expert, this year is the year with the smallest salmon migration in the Canadian province. Originally, the authorities expected 1.5 million salmon to migrate, which has now been reduced to about 600,000, a reduction of nearly half. The report points out that although the cause of salmon reduction is related to climate change, the harm caused by the farming industry cannot be ignored. Scholars have called on the government to expedite legislation to regulate these processing plants and aquaculture to protect the habitat of wild salmon
