Significant progress in seabream genetic improvement

FISBy Analia MuriasJune 11, 2012A team of scientists from the Aquaculture sub-programme of the Agrifood Research and Technology Institute (IRTA) in Spain and from the Laboratory of Physiology and Evolutionary Genomics of St. Andrews University in Scotland managed to sequence the transcriptome of the muscle of the gilt-head sea bream (Sparus aurata) for the first time.According to IRTA, this Read More…

Exploring ecosystems takes plenty of guts

Sydney Morning HeraldBy Nicky PhillipsJune 7, 2012 At the headquarters of the Secretariat of the Pacific Community in Noumea, Elodie Vourey pulls the stomach of a bigeye tuna from a large plastic bag and puts it on a white tray. With tweezers in one hand and a scalpel in the other, the laboratory assistant carves a deep incision into the fleshy organ, revealing the fish's last meal. Inside, a Read More…

Eating fish to keep your vision sharp in old age

New York Daily NewsJune 5, 2012 In yet another study touting the benefits of omega-3s in healthy aging, a new study out of Canada has found that choosing fish for dinner could help stave off age-related vision loss. In normal aging, vision loss results from the accumulation of a toxic molecule at the back of the eyes which builds up in the retina. But after feeding lab mice with an omega-3 Read More…

Eating Fish Can Protect Against Alzheimer’s

Fisher Center for Alzheimer's Research FoundationJune 4, 2012 Eating fish has long been linked with heart health. Now new research adds to growing evidence that fish is good for the brain as well. Researchers at the University of Pittsburgh found that people who ate baked or broiled fish just once a week had a lower risk of developing Alzheimer’s disease. They were also at lower risk of mild Read More…

Study shows consumers need more guidance about fish consumption…

EurekAlertJune 1, 2012 In a first-of-its kind summary of fish consumption choices, a team of researchers from Brigham and Women's Hospital has determined that consumers are not getting all the information they need to make informed decisions about fish consumption. Their research is published in the June 1 issue of Environmental Health Perspectives. The researchers, led by Susan Korrick, MD Read More…

Grazing snails rule the waves: marine study

PhysOrgBy Bob BealeMay 31, 2012The study published in the journal Ecology Letters is the largest of its kind ever undertaken into the ecological impacts of marine grazing animals: it was led by Associate Professor Alistair Poore, of the UNSW Evolution & Ecology Research Centre, who worked with an international team of 10 researchers.It found that, on average, marine herbivores remove almost Read More…

Stream temperatures don’t parallel warming climate trend

Red OrbitMay 3, 2012A new analysis of streams in the western United States with long-term monitoring programs has found that despite a general increase in air temperatures over the past several decades, streams are not necessarily warming at the same rate.Several factors may influence the discrepancy, researchers say, including snowmelt, interaction with groundwater, flow and discharge rates, Read More…

Escape response of small fish tested using a supercomputer

Phys.orgBy Simone UlmerMay 2, 2012Small fish bend themselves into a 'C' shape before they flee from predators. Observations have suggested that this shape helps them to abruptly put the greatest distance possible between themselves and their predators. ETH researchers have now tested this hypothesis for the first time using a supercomputer. Children playing in the sea never tire of trying to Read More…
