JUNEAU, Alaska, Dec. 21 /PRNewswire/ -- Today is the shortest day of the year. During the dark winter months, sunlight can be an insufficient source of vitamin D which is vital for the absorption of calcium and phosphorous. Low vitamin D levels have recently been linked to a greater chance of developing diseases including diabetes and heart disease, several cancers and the common cold. The good news is that there is a delicious and healthy, vitamin D rich food source, that's also one of...
Exposure to common pesticides may hinder the growth and survival of ESA-listed salmonBiologists determined that short-term, seasonal exposure to pesticides in rivers and basins may limit the growth and size of wild salmon populations. In addition to the widespread deterioration of salmon habitats, these findings suggest that exposure to commonly used pesticides may further inhibit the recovery of threatened or endangered populations."Major efforts are currently underway to restore...
Oil from soybeans modified through biotechnology increased levels of omega-3 eicosapentaenoic acid (EPA) in red blood cells according to research presented at the American Heart Association's Scientific Sessions 2009."This soybean oil could be an effective alternative to fish oil as a source of heart-healthy omega-3 fatty acids," said William Harris, Ph.D., lead author of the study and chief of cardiovascular health research at Sanford Research/USD and professor of medicine at Sanford School...
Children who eat fish more than 3 times per week show a worse performance in the general cognitive, executive and perceptual-manipulative areas. Those with higher levels of exposure to mercury show a generalized delay in cognitive, memory and verbal areas. Mercury is a contaminant found especially in oily fish and canned fish and to a lesser extent in white fish.This conclusion emerges from research conducted at the University of Granada, which warns of the need to assess children's health...
Canada is looking into why less sockeye salmon swam back to the Fraser River on the Pacific Coast this summer than the number that was predicted by scientists.Prime Minister Stephen Harper revealed the inquiry Thursday, noting that the federal government was worried about the shrinking numbers.Scientists had envisaged that about 13 million sockeye salmon would return for mating season, but only about 1.4 million fish actually came back.The decline was detrimental to the commercial Fraser...
Eight-year-old children who drink full-fat milk every day have a lower BMI than those who seldom drink milk. This is not the case for children who often drink medium-fat or low-fat milk. This is one conclusion of a thesis presented at the Sahlgrenska Academy.The study showed that children who drink full-fat milk every day weigh on average just over 4 kg less."This is an interesting observation, but we don't know why it is so. It may be the case that children who drink full-fat milk tend...
'No major role for fish' in the prevention of heart failure; only a possible beneficial effect in those with diabetesThe consumption of fish has no major role in the prevention of heart failure, according to results from a large prospective population study.(1) The study, which was started in 1990 and involved all men and women over the age of 55 living in a suburb of Rotterdam, found no difference in the risk of developing heart failure between those who did eat fish and those who didn't.The...
Temperature differences, slow water could delay ocean entryTemperature 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.A team of Northwest researchers are examining the unusual life cycle of the Clearwater's fall Chinook salmon to find out why some of them spend extra time in the cool Clearwater before braving the warm Snake....
Over a 23-year study, Javier Lobón-Cerviá has found the mechanism that controls the number of salmonids found each year in Cantabrian rivers. His method has been to monitor population numbers in relation to river flow in March, when the juvenile fish emerge. He concludes that environmental conditions change each year and modify river flow, positively or negatively affecting survival rates. This information throws light on a long debate within ecological theory about the mechanisms that...
A sonar station that counts salmon traveling up the Yukon River in Alaska malfunctioned this year, resulting in a smaller allowed catch, officials say. Russ Holder, federal fisheries manager for the Yukon, said the king salmon season looked like one of the poorest we've ever had, the Anchorage Daily News reported. In hindsight, it doesn't look as poor as those numbers indicated to us, he said. Because of the lower catch, enough fish got as far as the Canadian section of the river to fulfill...

The South American pilchard, Sardinops sagax, is a sardine of the Family Clupeidae, the only member of the genus Sardinops, found in the indo-Pacific oceans. Their length is up to 15.75 in (40 cm). It has a number of other common names: Australian pilchard, Blue pilchard, Blue-bait, Californian pilchard, Chilean sardine, Japanese pilchard, Pacific sardine, and Southern African pilchard. The South American pilchard is a coastal species that forms large schools. Coloration is blue green on...
The Atlantic herring, Clupea harengus, is the one of the most abundant species of fish on the planet. They can be found on both sides of the Atlantic Ocean congregating together in large schools (or swarms). They can grow up to 17.72 in (45 cm) in length and weigh more than 1.1 lb (0.5 kg). They feed on copepods, krill and small fish, and their natural predators are seals, whales, cod and other larger fish. The Atlantic herring fishery has long been an important part of the economy of New...
The Wolf herrings are a family (Chirocentridae) of two marine species of ray-finned fish related to the herrings. Both species have elongated bodies and jaws with long sharp teeth that facilitate their ravenous appetites, mostly for other fish. Both species reach a length of 3.28 ft (1 m). They have silvery sides and bluish backs. They are commercially fished, and marketed fresh or frozen.
Australian salmon are medium-sized perciform marine fish of the small family Arripidae. Four species are recognized, all within the genus Arripis; they are found in the waters off southern Australia (including Tasmania) and New Zealand. Despite the common name, Australian salmon are not related to the salmon (family Salmonidae) of the Northern Hemisphere; the former were named so by early European settlers after their superficial resemblance to the salmoniform fishes. Relatively long-lived...
Atlantic salmon (Salmo salar, from the Latin words "Salmo" meaning salmon, and "salar" meaning "leaper") is a species of fish in the Salmonidae found in the northern Atlantic Ocean and in rivers that flow into the Atlantic. It breeds in the rivers of Western Europe from northern Portugal north to arctic Norway, Iceland, Greenland, and the east coast of North America from Connecticut in the United States north to northern Labrador in arctic Canada. At sea, it is found mainly in the waters...
