Farm salmon pose clear reproductive threat to wild gene pools
Farmed salmon show full reproductive potential to invade wild gene pools and should be sterilised - according to new research from the University of East Anglia (UEA).
Smaller salmon spawn better in riverbeds than larger counterparts
For salmon, being bigger isn't always better. Being a little smaller—at least intermediate size—is more advantageous for maximum spawning in riverbeds, a University of Wyoming researcher recently discovered.
Genetic chip will help salmon farmers breed better fish
Atlantic salmon production could be boosted by a new technology that will help select the best fish for breeding.
Link confirmed between salmon migration, magnetic field
A team of scientists last year presented evidence of a correlation between the migration patterns of ocean salmon and the Earth's magnetic field, suggesting it may help explain how the fish can navigate across ...
Minnow to be 1st fish taken off endangered list
A tiny minnow that lives only in Oregon is set to become the first fish ever taken off U.S. Endangered Species Act protection because it is no longer threatened with extinction.
Tracking young salmon's first moves in the ocean
Basic ocean conditions such as current directions and water temperature play a huge role in determining the behavior of young migrating salmon as they move from rivers and hit ocean waters for the first time, ...
Surface water is a key factor in the transmission of pancreas disease in salmon
Anne Stene's PhD thesis explains how environmental factors affect the outbreak and transmission of pancreas disease (PD) in farmed salmon.
What you need to know about jellyfish attacks on salmon farms
Tens of thousands of farmed salmon are dead after a swarm of mauve stinger jellyfish swept through an open-ocean salmon farm in Ireland. Tourists in France and Spain must contend with these summer visitors, ...
For fish and rice to thrive in Yolo Bypass, 'just add water'
From a fish-eye view, rice fields in California's Yolo Bypass provide an all-you-can-eat bug buffet for juvenile salmon seeking nourishment on their journey to the sea. That's according to a new report detailing ...
Melanin pigmentation in salmon fillets—causes and risk factors
A PhD project carried out at the Norwegian School of Veterinary Science has examined the unwanted discoloration, or melanin "black spots", of muscle fillets from farmed salmon.
Improving salmon's success in the wild and aquaculture
Have you ever been stressed and forgot what you were doing? Chronic mild stress may explain why many salmon don´t return to our rivers and why 20% of salmon production is lost every year.
Wake up and smell the reef: Fish larvae sniff their way back home
How tiny fish larvae travel away from the reef, then know how to navigate their way back home is a scientific mystery.
Sterile farmed salmon can reduce genetic impact on wild fish
Interbreeding between escaped farmed salmon and their wild counterparts is a major headache for the aquaculture industry. Now Norwegian fish farming companies are raising one million sterile salmon in sea ...
Research shows how females choose the 'right' sperm
University of East Anglia scientists have revealed how females select the 'right' sperm to fertilize their eggs when faced with the risk of being fertilized by wrong sperm from a different species.
