The first cardiovascular health study in China investigating the effect of seafood consumption on health parameters, shows a 20% decrease in disease markers in patients consuming salmon for lunch 5 times per week, for 8 weeks. The results were recently announced in a Chinese-Norwegian seafood seminar during a fisheries fair in Qingdao, China. Globally, many countries are battling lifestyle diseases and the trend is rising, also in China and Norway. Both countries sees an increase of...

Just after Americans have headed to the polls to elect their next president, a new report in the November 13th issue of Current Biology, a Cell Press publication, reveals how one species of fish picks its leaders: Most of the time they reach a consensus to go for the more attractive of two candidates. "It turned out that stickleback fish preferred to follow larger over smaller leaders," said Ashley Ward of Sydney University. "Not only that, but they also preferred fat...

University of British Columbia researchers have found a way to accurately predict the impact of climate change on imperilled Pacific salmon stocks that could result in better management strategies. The findings, among the first to quantify a relationship between river temperature and salmon mortality rate, are published in the current issue of the journal Physiological and Biochemical Zoology. While climate change and rising river temperatures have been linked to dwindling salmon...

The National Institute of Nutrition and Seafood Research (NIFES) has identified a number of genes in various organs involved in the salmon`s lipid metabolism. Studies of these genes show that vegetable oils in the feed affect expression of lipid metabolism genes. The fatty acids in the salmon lipid stores reflects the feed fatty acid composition. Accordingly, when the salmon is fed vegetable oils as a substitute for fish oils, the fatty acid profile changes in the fish. Vegetable oils...

New study on landscape around Chesapeake Bay says imbalance in nitrogen cycle is damaging water quality and fish populations. A rise in carbon emissions is not the only threat to the planet. Changes to the nitrogen cycle, caused in large part by the widespread use of fertilizers, are also damaging both water quality and aquatic life. These concerns are highlighted by Professor Grace Brush, from Johns Hopkins University in Baltimore, USA, in her historical review1 of landscape...

Trials on shrimp shell fertiliser implemented in the north over summer confirm the waste is well suited. However, considerable testing and analysis remains until the product goes on sale. Nofima Ingredients in Bergen has developed a technique to produce pellets from shrimp shell on commission for potato producers' organisation Ottar. The pellets were tested over the summer in small-scale trials in a climate laboratory and large-scale field trials at Bioforsk Nord and in the...

German health authorities recently detected banned chemicals in Chilean farmed salmon, Ecoceanos News reported last week. Germany’s Federal Office for Consumer Protection and Food Safety, or BVL, recently tested 42 samples of Chilean-raised farmed salmon. In two of those samples, BVL officials found traces of crystal violet, an anti-fungal chemical believed to have potentially carcinogenic properties. Crystal violet is not allowed in food exported to the European Union. BVL investigators...

A genetic study of a fish that lives in the icy waters off Antarctica sheds light on the adaptations that enable it to survive in one of the harshest environments on the planet. The study, in the Proceedings of the National Academy of Sciences, is the first to search the genome of an Antarctic notothenioid fish for clues to its astounding hardiness. There are eight families of notothenioid fish, and five of them inhabit the Southern Ocean, the frigid sea that encircles the...

Researchers at the Tainan-based National Cheng Kung University (NCKU) have invented a new way to extract pollution-free docosa hexaenoic acid (DHA) from an indigenous species of algae that could revolutionize the way the supplement is produced commercially, academic sources said Wednesday. Team members said DHA is normally derived from fish and shellfish, but minute quantity of toxins -- such as methyl mercury or dioxins -- may migrate from the fish to the DHA, a common nutritional...

The President of SINTEF Fisheries and Aquaculture, Karl Andreas Almås, crouches over his laptop, opens one of his presentations and finds an illustration. It shows one red curve and one blue one. He then indicates the point where they meet each other, then frowns and says the message he cannot repeat often enough: There is a huge gap between world demand for fish and what we can harvest from the world’s natural stocks. The figures are clear: If we don’t do something about the over fishing, the...

Fresh hopes for cancer research have been found in the slimy mucus produced by a sea snail. An anti-cancer agent found in the purple secretion that the sea snail uses to protect its eggs could be used to tackle breast cancer. The AMP Foundation and Kingsford Financial Group have sponsored Flinders Medical Centre PhD student Mr Chuang Ching Er – known to his colleagues as Lawrence - to investigate the link. One of Mr Er's supervisors, Dr Kirsten Benkendorff, said the snails...
