New Virus Associated With (But Not Causing) Mass Oyster Die-Offs

UBC researchers found a new virus in farmed Pacific Oysters that perished during a mass die-off in 2020. 

During the die-off, researchers collected 33 dead oysters as well as 26 wild oysters from neighbouring sites. Pacific Oyster Nidovirus 1 (PONV1) was only found in 20 of the dead or dying farmed oysters.

Dr Kevin Xu Zhong, a research associate in the UBC department of Earth, Ocean and Atmospheric Sciences (EOAS), explained this does not mean the virus was the cause of death.

“We found this new virus. There is no indication it is causing the mortality mentioned in the database, the study, or the reporting.”

Fisheries and Oceans Canada faces deluge of calls to improve ‘suspect’ science

Canada’s National Observer, Local Journalism Initiative Reporter

The Department of Fisheries and Oceans is being flooded with calls for change after a parliamentary committee examined how the federal agency conducts, interprets and acts on its own science. 

The investigation ended with 49 recommendations to address concerns about how DFO science is presented to the fisheries minister and the public before important political decisions are made — particularly those involving B.C. salmon farms or commercial fisheries on either coast.

Report of the Standing Committee on Fisheries and Oceans

Originally published by the Parliament of Canada

On 1 February 2022, the House of Commons Standing Committee on Fisheries and Oceans (the Committee) agreed to undertake a study to “examine how the Department of Fisheries and Oceans prioritizes, resources and develops scientific studies and advice for the department, how the results of scientific study are communicated to the Minister and Canadians, and how the minister applies data and advice provided by the department and other government departments to ministerial decisions.”The Committee heard from 57 witnesses over nine meetings held between 26 April 2022 and 7 October 2022.

70% of the fish farms sampled had PRV-1, study finds

1 Comment

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.”

In the first of a series of posts gleaned from the Standing Committee on Fisheries and Oceans, a top UBC geneticist testifies on DFO’s failure to follow up on the findings of its own scientists and those from the international community, regarding the threat that Piscine Orthoreovirus or PRV  poses to the wild salmon population. The following audio is taken from the testimony that Dr Gideon Mordecai gave on Thursday, May 5, 2022.
