Why ‘normal’ salmon don’t get as many parasites

New research reveals the inherent ability of salmon to avoid infection through their first line of defense—behavior. In the rapidly growing fish-farming industry, parasite outbreaks cause production inefficiencies, poor welfare for billions of fish, and negative consequences for wild populations when diseases spread. “Parasite outbreaks in wild fish have been induced by farmed fish in major farming systems, such as sea lice infestations on wild salmon in Europe and North America,” says Tim Dempster, associate professor in the School of BioSciences at the University of Melbourne. click here to read the story 15:25

Farmed Salmon on the loose! Storm damages an aquaculture pen at the mouth of Shelburne Harbour

Provincial fisheries inspectors are investigating the escape of possibly hundreds of market-ready salmon from an aquaculture pen at the mouth of Shelburne Harbour. Employees at Cooke Aquaculture noticed a breach in one of the company’s enclosures last Wednesday and notified the province. They discovered some fish had escaped two days later, said Krista Higdon, a spokeswoman for the Nova Scotia Department of Fisheries and Aquaculture. Cooke spokeswoman Nell Halse said it appeared wind and waves associated with recent winter storms knocked over one of the moorings and that created a breach in one of the enclosures. She said the company was still trying to determine how many fish might have slipped free. continue reading here 17:34

 Hybridization – Escaped farmed salmon are breeding with wild salmon and producing offspring

nl-aquaculture-fish-farming-cage-open-water-20130927Research has confirmed that escaped farmed salmon are breeding with wild salmon and producing offspring in many rivers in Newfoundland. “We did find evidence of successful breeding between farmed and wild salmon. Approximately a third of the individuals we sampled showed evidence of hybrid ancestry,” said Department of Fisheries and Oceans scientist Ian Bradbury, of the unpublished study presented at an international aquaculture conference in St. John’s on Tuesday. Researchers studied thousands of fish in 18 rivers on the island’s south coast, and found evidence of interbreeding in 17 of them. “It was widespread across a suite of the rivers that we looked at. I think there was only one river where we didn’t see evidence of hybridization,” said Bradbury. It’s estimated that over the decades since the advent of aquaculture, more than 750,000 salmon have escaped from fish farms in the province. The new study sheds light on what happens to them in the wild. Read the story here 11:26

What are the fish telling us: the story of the world’s largest wild salmon fishery

Imported LayersThe myth (it was a myth) goes that when Christopher Columbus sailed to the Americas in 1492, he and his crew couldn’t sleep because of the perpetual whack of sea turtles bumping against the hull of their ship. Now, 500 years later, nearly every species of sea turtle is listed as endangered. In fact, so many plants and animals have become endangered or extinct in recent years, that researchers and environmentalists have started referring to it as the sixth mass extinction.

It seems not everyone cares for Farmed Salmon! – Farmed salmon not fit for consumption

After reading the June 2 letter on farmed salmon by Jon Grant, NSERC-Cooke Industrial Research Chair in Sustainable Aquaculture at Dalhousie University, I had the feeling of being dismissed as: “What do I know, as I am not a scientist but only a mother?”However, I am also a businesswoman and co-owner of two restaurants. After doing my own research, and a lot of it — yes, I can read — on farmed Atlantic salmon, my conclusion was,,, Read the rest here  09:19

Sterilise farmed salmon to stop breeding with wild fish, researchers say

New research shows that while salmon bred in captivity for food consumption are genetically different from their wild relatives, they are just as fertile, potentially damaging wild populations if they escape and breed with them. Read more here guardian 10:26

Believe it or Not! An Oceana post – The Washington Post is Wrong About Farmed Salmon

We’re here to set the record straight: farmed salmon are not a sustainable seafood choice, and they’re not good for the oceans. If you want to be a responsible seafood eater, therefore, you should not eat farmed salmon. [email protected] 07:26
