Trout trick-or-treat: Fish gobble furry animals with four feet
Freshwater fish with bellies full of shrews – one trout a few years back was found to have eaten 19 – aren't as random as scientists have thought.
Detecting and preventing disease in trout
Each year, the rainbow trout industry suffers significant economic losses due to bacterial cold-water disease, caused by the bacterium Flavobacterium psychrophilum. The disease also affects salmon and other ...
Climate change accelerates hybridization between native and invasive species of trout
(Phys.org) —Scientists have discovered that the rapid spread of hybridization between a native species and an invasive species of trout in the wild is strongly linked to changes in climate.
Rainbow trout genome sequenced
Using fish bred at Washington State University, an international team of researchers has mapped the genetic profile of the rainbow trout, a versatile salmonid whose relatively recent genetic history opens ...
Speed trap for fish catches domestic trout moving too slow
Washington State University researchers have documented dramatic differences in the swimming ability of domesticated trout and their wilder relatives. The study calls into question the ability of hatcheries ...
3D scans map widespread fish disease
Seventy-five per cent of antibiotics in Danish fish farms is used to treat fish with enteric redmouth disease. With the help of 3D scans, researchers at the University of Copenhagen have mapped how the fish are infected with ...
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 ...
Spicing up your fish fillets with science
The health benefits of consuming omega-3 long chain polyunsaturated fatty acids such as EPA and DHA are well established. The primary sources of these fatty acids in the human diet are through fish and seafood. Researchers ...
New underwater robot swims and senses like a fish
In recent years, robotic underwater vehicles have become more common in a variety of industrial and civil sectors. They are used extensively by the scientific community to study the ocean. For example, underwater ...
Shedding light on the senses fish use for navigation
(Phys.org) —New research conducted at Queen's University has discovered that polarized light vision, which is used for navigation and orientation by rainbow trout, changes with age.
Fatty acid binding protein (Fabp2) in Atlantic salmon and rainbow trout
Feeding fish with plant-based raw materials has been shown to have a negative effect on Atlantic salmon's ability to digest fats.
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.
Fish feed for sustainable aquaculture
Norwegian researchers have been leading an international effort to make aquaculture more sustainable. In 10 years they have revolutionised fish feed.
Antimicrobial resistance in fish pathogenic bacteria and other bacteria in aquatic environments
Little attention has been paid to the use of antibiotics in the aquaculture industry as one reason for the increase in bacteria resistant to antibiotics and the spread of such resistance to other bacteria.
