The future of fish farms in British Columbia is uncertain. On June 7, Judge Paul Favel supported the Ministry of Fisheries decision to not renew the licenses of 15 fish farms in the Discovery Islands, and denied a joint application by industry and the Laich-kwil-tach Nation for a judicial review. At the end of this month the licenses of the remaining 66 fish farms still operating in this province will expire.

Scientists at the University of Gothenburg in Sweden recently concluded that some farmed salmon die from depression. (This may not be too surprising, given the conditions in which they are kept.) In other recent research, a team of US and Canadian scientists has charted an ominous trend: mass die-offs of farmed salmon are increasing in both frequency and scale. Some observers question whether the industry, after decades of growth, may be past its peak and about to decline.
Meanwhile, DFO suggests that salmon farming licenses should be renewed this summer for six years rather than the current standard term of two years — only five years after Prime Minister Justin Trudeau made a campaign promise to shut down net-pen salmon farming in BC altogether by 2025.

Sea lice are a serious problem for the fish farm sector, but a new study from the University of British Columbia has found there are viruses that prey upon them.
“In theory viruses might be deployed in a way in which they might be able to help control sea ice densities in aquaculture. I certainly wouldn’t be a proponent of that at this stage, and would strongly advise against that because we just don’t know enough about it,” explained senior author Dr. Curtis Suttle.

Wild salmon infected with that virus would have swam by neighbouring Cortes, Read and Quadra Islands on their way home to spawn.
Dr Gideon Mordecai is a Research Associate with the Institute for the Oceans and Fisheries at UBC. He is also the author of more than 20 scientific publications, the most recent of which reported the PRV1a virus was in 70% of the samples they studied from 56 fish farms.
Cortes Currents asked Dr. Mordecai,”Fish farms are claiming that BC’s PRV1 isn’t deadly for wild salmon. Is that true?”

A new study published by the Canadian Journal of Fisheries and Aquatic Sciences, states that 70% of the samples taken from 56 fish farms had PRV-1.
One of the co-authors is independent biologist Alexandra Morton, who explained, “The study was my concept and I funded a lot of the analysis and did a lot of the sampling myself. It was truly collaborative with Clayoquot Action sampling the Farms in Clayoquot Sound. An extraordinary man, Dr. Neil Fraser from Powell River got in his speed boat and went to the central coast. The Wild Fish Conservancy down in Washington State, sampled farms there. So it was a sustained effort by a lot of people, and then Dr. Gideon Mordecai did the analysis of the relationship between the different strains that we picked up.”
