Columbia research shows novel benefits of fatty acids in arteries
New research from Columbia University Medical Center continues to shed light on the benefits of making fish a staple of any diet. view more (2009-02-06)
All species are not created equal when assessing the impacts of species loss on ecosystems
Numerous studies have shown that when species are randomly lost from communities, ecosystem function declines. But such patterns of species loss do not reflect those in natural communities where major drivers of change, such as stress and disturbance, cause preferential loss of rare and uncommon species. In the June issue of Ecology Letters, Smith... view more... (2003-05-22)
Fourth Biennial European Conference on Fish Processing - SCI Conference Connects International Industry Experts
Fish stocks and supply, quality and safety issues and the science and technology of fish processing are the three industry areas to be covered at the Fourth Biennial European Conference on Fish Processing to be held from 3-5 July 2001 at Great Grimsby Town Hall, UK. Speakers from three continents will cover areas and issues ranging from quality... view more... (2001-05-09)
Tiny zebras at your service
Before new pesticides can be approved, their environmental impact must be assessed. Due to the complexity of ecological systems, researchers require simple yet representative laboratory models. Among vertebrates, schools of zebra fish are especially suitable. --- Studying the ways substances affect living organisms in their environment is the job... view more... (2004-02-03)
Climate change has surprising effect on endangered naked carp
Forthcoming in the January/February 2007 issue of Physiological and Biochemical Zoology, a groundbreaking study reveals an unanticipated way freshwater fish may respond to water diversion and climate change. view more (2006-12-20)
UBC researcher gives first-ever estimate of worldwide fish biomass and impact on climate change
Are there really plenty of fish in the sea? University of British Columbia fisheries researcher Villy Christensen gives the first-ever estimate of total fish biomass in our oceans: Two billion tonnes. view more (2009-01-16)
New Ballast Treatment Could Help Shield Lake Superior from Deadly Fish Disease

Insomniac fish shed light on the molecular basis of sleep disorders
Sleep disorders are common and poorly understood. In humans, narcolepsy is a sleep disorder associated with sleepiness, abnormal dreaming, paralysis and insomnia. view more (2007-10-16)
sexing sticklebacks
I raise an eyebrow slightly. Dr Richard Griffiths is telling me about his research on Gasterosterus aculeatus. More specifically about his efforts to harness the power of modern genetic science to sex a "¦ stickleback? view more (1999-11-05)
Can we identify escaped salmon by means of their DNA?
Escaped salmon are a problem for the fish-farming industry. Is it possible to identify the fish-farm from which salmon have escaped by testing a sample of their DNA? Scientists at the Institute of Marine Research in Bergen have been looking into the prospects of doing so. view more (2004-08-31)
Estrogen Linked to Lowered Immunity in Fish
Exposure to estrogen reduces production of immune-related proteins in fish. This suggests that certain compounds, known as endocrine disruptors, may make fish more susceptible to disease. view more (2009-06-04)
Fishing for the Origins of Genome Complexity
Biologists at Georgia Tech have provided scientific support for a controversial hypothesis that has divided the fields of evolutionary genomics and evolutionary developmental biology, popularly known as evo devo, for two years. view more (2005-12-16)
Fish really is brain food
Researchers at the University of Bristol have found that mums-to-be who eat oily fish such as sardines and mackerel have children whose visual development is better. This positive association was also seen for breastfeeding. The findings were announced by Dr Cathy Williams, the eye expert on the Children of the 90s project. This study based in... view more...

Low oxygen in coastal waters impairs fish reproduction
Low oxygen levels in coastal waters interfere with fish reproduction by disrupting the fishes' hormones, a marine scientist from The University of Texas at Austin Marine Science Institute has found. view more (2007-08-29)
Poachers impact the future of salmon
The riches of the country seemed inexhaustible. However, human beings have a lot of impact on the nature. Let's consider for example the Kamchatka salmons. Within the last 10-15 years the quantity of silversides (Oncorhynchus kisutch) reduced by several times. Prohibition of this species fishing is under discussion now. And king salmon... view more...

New dinosaur species possible in Northwestern Alberta
The discovery of a gruesome feeding frenzy that played out 73 million years ago in northwestern Alberta may also lead to the discovery of new dinosaur species in northwestern Alberta. view more (2009-05-13)
For some young fish, early gene expression is a clear harbinger of fated lifestyle
As juveniles, individuals of many fish species face a developmental choice that will profoundly affect their future: whether to adopt a sedentary or migratory lifestyle. view more (2006-04-18)
