Evolution at warp speed: Hatcheries change salmon genetics after a single generation
The impact of hatcheries on salmon is so profound that in just one generation traits are selected that allow fish to survive and prosper in the hatchery environment, at the cost of their ability to thrive ...
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).
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 ...
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.
Salmon runs boom, go bust over centuries
Salmon runs are notoriously variable: strong one year, and weak the next. New research shows that the same may be true from one century to the next.
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.
Aquatic playground can turn water tanks into fish schools
Raising fish in tanks that contain hiding places and other obstacles can make the fish both smarter and improve their chances of survival when they are released into the wild, according to an international ...
Japan scientists breed salmon from surrogates
Japanese scientists have successfully bred a type of salmon using surrogate parents of a different species, in a breakthrough that could help preserve endangered creatures, the chief researcher said Tuesday.
Researchers improve zebrafish cloning methods
A team of Michigan State University researchers has developed a new, more efficient way of cloning zebra fish, a breakthrough that could have implications for human health research.
Alaskan researchers find evidence of genetic change in salmon in response to warming climate
Salmon can sniff out predators
Salmon know when their most common predator is around, because they can tell that it's eaten salmon before, new research shows. Young fish can do this too, even if they've never encountered that particular ...
Salmon and other fish predators rely on 'no guts, no glory' survival tactic
The phrase "no guts, no glory" doesn't just apply to athletes who are striving to excel.
Gene-flaw, virus could be killing Pacific salmon
Massive die-offs among Canada's wild sockeye salmon could be due to a genetic flaw that causes immune weakness and could make viruses lethal, researchers said Thursday.
