UIC biologists use DNA to study migration of threatened whale sharks
Whale sharks -- giants of the fish world that strike terror only among tiny creatures like the plankton and krill they eat -- are imperiled by over-fishing of the species in parts of its ocean range. view more (2009-04-08)
Eating fish cuts risk of dementia
Elderly people who eat fish or seafood at least once a week are at lower risk of developing dementia, including Alzheimer's disease, finds a study in this week's BMJ. Using data from a large ageing study, a team of French researchers set out to test whether there was a relation between consumption of fish (rich in polyunsaturated fatty acids) or... view more...

Naming evolution's winners and losers
Mammals and many species of birds and fish are among evolution's "winners," while crocodiles, alligators and a reptile cousin of snakes known as the tuatara are among the losers, according to new research by UCLA scientists and colleagues. view more (2009-07-29)
Human impacts and environmental factors are changing the northwest Atlantic ecosystem
Fish in U.S. waters from Cape Hatteras to the Canadian border have moved away from their traditional, long-time habitats over the past four decades because of fundamental changes in the regional ecosystem. view more (2009-09-01)
Help for climate-stressed corals
Banning or restricting the use of certain types of fishing gear could help the world's coral reefs and their fish populations survive the onslaughts of climate change according to a study by the ARC Centre of Excellence for Coral Reef Studies at James Cook University, the Wildlife Conservation Society, and other groups. view more (2009-06-18)
Healthy coral reefs of Madagascar resisting damage from climate change
Healthy coral reefs of Madagascar's northeast coast have so far resisted the damaging effects of warmer ocean temperatures attributed to global climate change, say scientists who recently studied the region. view more (2006-06-23)
A new chemical method for distinguishing between farmed and wild salmon
Wild salmon and farmed salmon can now be distinguished from each other by a technique that examines the chemistry of their scales. view more (2009-09-30)
NOAA Researchers Help Build a Global Reference Library of DNA Barcodes
Most of us are familiar with bar codes, those small black stripes with numbers below, known as the Universal Product Code or UPC label, that appear on commercial products. We scan them at the grocery store or to check a price, or have to cut them out and send them in for a rebate. view more (2008-04-21)
'Killer' B cells provide new link in the evolution of immunity
Researchers from the University of Pennsylvania School of Veterinary Medicine have discovered a unique evolutionary link between the most primitive innate form of immune defense, which has survived in fish, to the more advanced, adaptive immune response present in humans and other mammals. view more (2006-10-04)

Prenatal Exposure To Mercury In Fish Not Associated With Impaired Neurodevelopment (p 1667, 1686)
Authors of a longitudinal study investigating a possible link between prenatal mercury exposure from ocean fish and impaired neurodevelopment in children report their latest findings in this week's issue of THE LANCET. The results confirm earlier findings that prenatal exposure to mercury in the Seychelles-where fish consumption is the main... view more... (2003-05-14)
Introduced marine species get larger in the invaded region
The transport of species outside their native region through human activities has often had a dramatic impact on the ecosystems into which these species are introduced and on the surrounding economies. The consequences of introduction for the introduced species itself, including changes in body size and shape, are less recognized. Prior studies of... view more... (2003-08-13)
Consumption of fish oil does not appear to protect against abnormal heart rhythms
Patients with an implantable cardioverter defibrillator did not have a significantly lower risk of serious abnormal heart rhythms or death by consuming fish oil supplements, which had been thought to have a protective effect. view more (2006-06-14)
First direct evidence of substantial fish consumption by early modern humans in China
Freshwater fish are an important part of the diet of many peoples around the world, but it has been unclear when fish became an important part of the year-round diet for early humans. view more (2009-07-07)
Net closes in on fish oil paradox: why it helps some people but not others
Not everyone can benefit from fish oil. Although it has been known for many years to relieve the symptoms of inflammatory diseases, such as rheumatoid arthritis, its beneficial effects are not universal. Indeed, in some people it has no anti-inflammatory effect at all. Now researchers at the University of Southampton`s Institute of Human Nutrition... view more... (2002-07-31)
New fossil tells how piranhas got their teeth
How did piranhas - the legendary freshwater fish with the razor bite - get their telltale teeth? view more (2009-06-26)
DNA evidence is in, newly discovered species of fish dubbed H. psychedelica
"Psychedelica" seems the perfect name for a species of fish that is a wild swirl of tan and peach zebra stripes and behaves in ways contrary to its brethren. So says University of Washington's Ted Pietsch, who is the first to describe the new species in the scientific literature and thus the one to select the name. view more (2009-02-25)
Geomagnetic field is necessary for health
The consequences of isolation from natural geomagnetic field have been investigated via experiments with salmon fry by Oleg Zaporozhets, Doctor of Biology, Kamchatka Research Institute of Fish Industry And Oceanography. Salmon fry raised for release into rivers are kept in large pools. Fish survival and growth rate depend on diverse factors: pool... view more... (2003-07-18)
Fatty fish consumption associated with lower risk of kidney cancer in women
Preliminary research suggests that higher consumption of fatty fish in women is linked with a lower risk of renal cell carcinoma, a common form of kidney cancer. view more (2006-09-20)
University of Hawaii at Manoa oceanographers examine mercury levels of pelagic fish in Hawaii
In the open ocean, species of large predatory fish will swim and hunt for food at various depths, which leads to unique diets in these fish. view more (2009-09-01)
