Salmon migration mystery explored on Idaho's Clearwater River
Temperature differences and slow-moving water at the confluence of the Clearwater and Snake rivers in Idaho might delay the migration of threatened juvenile salmon and allow them to grow larger before reaching the Pacific Ocean. view more (2009-09-18)
Half of the fish consumed globally is now raised on farms, study finds
Aquaculture, once a fledgling industry, now accounts for 50 percent of the fish consumed globally, according to a new report by an international team of researchers. And while the industry is more efficient than ever, it is also putting a significant strain on marine resources by consuming large amounts of feed made from wild fish harvested from... view more...

Shifting baselines confound river restoration
Steep reductions in the abundance of fish, shellfish, and other aquatic fauna in recent centuries are not restricted to animals that live in the sea: historical records show that species in rivers and lakes worldwide also experienced sharp declines. view more (2009-09-01)
Changes in net flow of ocean heat correlate with past climate anomalies
Physicists at the University of Rochester have combed through data from satellites and ocean buoys and found evidence that in the last 50 years, the net flow of heat into and out of the oceans has changed direction three times. view more (2009-08-17)
Sick fish may get sicker
Entire populations of North American fish already are being affected by several emerging diseases, a problem that threatens to increase in the future with climate change and other stresses on aquatic ecosystems, according to a noted U.S. Geological Survey researcher giving an invited talk on this subject today at the Wildlife Disease Association... view more...

NOAA Report Finds Threats to California's Cordell Bank Marine Sanctuary
A new NOAA report on the health of Cordell Bank National Marine Sanctuary indicates that the overall condition of the sanctuary's marine life and habitats is fair to good, but identifies several emerging threats to sanctuary resources. view more (2009-06-19)
Omega-3 fatty acids appear to impact AMD progression
Omega-3 fatty acids found in fatty fish such as tuna and salmon may protect against progression of age-related macular degeneration (AMD), but the benefits appear to depend on the stage of disease and whether certain supplements are taken. view more (2009-06-18)
Eating fatty fish once a week reduces men's risk of heart failure
Eating salmon or other fatty fish just once a week helped reduce men's risk of heart failure, adding to growing evidence that omega-3 fatty acids are of benefit to cardiac health. Led by researchers at Beth Israel Deaconess Medical Center (BIDMC) and reported in today's on-line issue of the European Heart Journal, the findings represent one of the... view more... (2009-04-22)
Invasives threaten salmon in Pacific Northwest

A reversal of thinking: How women with lupus can increase chance for healthy pregnancies
In the not so distant past, women with systemic lupus erythematosus (SLE), an autoimmune disease, were advised not to have children, and if they became pregnant, to have therapeutic abortions to prevent severe flares of their lupus. view more (2008-10-27)
Case Western Reserve University project ties soil conservation and river management together
Sediment in rivers comes from erosion of the landscape as well as the erosion and collapse of the banks themselves. Just how much each source contributes to a river - and how it affects the flow and path of that river - is the subject of research by Peter Whiting, professor of geological sciences at Case Western Reserve University. view more (2008-10-02)
