New research shows wild salmon exposed to fish farms have ‘much higher’ rate of disease

Wild salmon exposed to open-net fish farms are much more likely to be infected with piscine reovirus (PRV) than those that don’t have that contact, a new study has concluded. The data also show that the virus makes it more difficult for wild salmon to swim upstream to their spawning grounds, which has major implications for the sustainability of the populations. “The government has to remove this industry from the key salmon migration routes or we risk the complete loss of wild salmon in this province,” said Alexandra Morton, lead author on the report and an outspoken advocate for wild salmon. click here to read the story 18:07

Public urged to remain vigilant after Pacific salmon found in Irish rivers

Thirty Pacific salmon have been found in nine Irish river systems since the first one was recorded in late June. Fisheries chiefs said one of the most recent non-native fish to be captured was a mature male, which was ready to spawn when it was found on August 9 on the Erriff in Co Mayo. It has been suggested that some of the Pacific species have made their way south after “straying” from rivers in northern Norway or Russia. They were introduced to some Russian fisheries in the 1960s and have colonised west along Arctic coasts. click here to read the story  09:02

Update: No Fukushima Contamination Detected in Pacific Salmon Off North American Coast

The Integrated Fukushima Ocean Radionuclide Monitoring (InFORM) project is a network involving academic, governmental, and non-governmental organizations, as well as citizen scientists. InFORM is acquiring data to support a thorough radiological impact assessment for Canada’s west coast stemming from the Fukushima Dai-ichi nuclear power plant (FD-NPP) accident, and to effectively communicate these results to the public.

Salmon in NY waters have complex natural instincts

Chinook, or king, salmon are stocked in New York waters. These fish actually are Pacific salmon that are raised in state hatcheries, said Matt Sanderson, a regional fisheries biologist with the New York Department of Environmental Conservation. Brown trout and coho salmon also are stocked by the state. [email protected] 08:40

Opinion: Some students learn from mistakes – Jack Emberly, retired teacher, local author and environmentalist.

Maple Ridge News – In the 1960s, the DFO paid $15 for harbor seal “snouts,” proof an enemy of Pacific salmon had been killed. Bounty hunters – commercial and recreational fishermen eager to help the cause – shot thousands of animals. Many seals sank before they could give up their noses. Dr. Lance Barrett-Lennard, biologist Vancouver Aquarium, recalls this culling campaign as an example of government tinkering with a perfectly self-regulating bio-system. alrighty then ,,,,,,,,,continued
