The Journal of Parasitology presents a study featuring a new method of identifying parasites in various fish species. The results allow researches to identify known parasites in a similar fish species to estimate parasite compatibility with the host they are studying. Lawrence, KS (PRWEB) February 18, 2013 The Journal of Parasitology — We can learn a lot about fish from their parasites. One population of fish, for instance, might be distinguished from another of the same species by...

Antibiotic Resistance Is A Problem For The Ornamental Fish Industry
2013-01-15 16:43:45

Oregon State University The $15 billion ornamental fish industry faces a global problem with antibiotic resistance, a new study concludes, raising concern that treatments for fish diseases may not work when needed — and creating yet another mechanism for exposing humans to antibiotic-resistant bacteria. The risk to humans is probably minor unless they frequently work with fish or have compromised immune systems, researchers said, although transmission of disease from tropical fish...

Worms infecting fish grow 4 times faster at higher temperatures and manipulate the behavior of fish Parasitic worms that infect fish, and have a devastating effect on fish reproduction, grow four times faster at higher temperatures — providing some of the first evidence that global warming affects the interactions between parasites and their hosts. The study from the University of Leicester revealed that global warming had the potential to change the balance between parasite and...

A recent study suggests that parasites in fish, including threatened species of Oregon coho salmon, may have more profound impacts on fish health than has been assumed, and could be one of the key mechanisms by which habitat and land use changes cause salmon mortality. It's not just the presence or absence of parasites that is important, the research found, but their numbers that can build up over years or decades and ultimately cause major impacts. The study will be published soon in the...

Study is first to combine 10 years of farms' sea-lice counts and 60 years of wild fish counts A new UC Davis study contradicts earlier reports that salmon farms were responsible for the 2002 population crash of wild pink salmon in the Broughton Archipelago of western Canada. The Broughton crash has become a rallying event for people concerned about the potential environmental effects of open-net salmon farming, which has become a $10 billion industry worldwide, producing nearly 1.5 million...

Climate change and other stresses expected to affect entire populations of fishEntire 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 conference in Blaine, Wash."A generation ago, we couldn't have imaged...

Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have gained a key insight into a disease that is devastating the UK's fish farming industry. The researchers have discovered that fish can harbour and spread proliferative kidney disease (PKD), a cause of major stock losses on fish farms, as well as being affected by the infection.The discovery now paves the way for research to develop effective ways to combat the disease. The research was conducted by...

By ART HOLDEN By ART HOLDEN Daily Record Outdoor Editor While some stories have called it "an escaped killer," the recent viral hemorrhagic septicemia disease discovered recently in fish in Clear Fork Reservoir isn't the concern some make it out to be, and definitely is not of concern for humans. VHS was detected in Clear Fork back in April, making the Lexington-area reservoir the first inland lake in the United States to test positive for the fish-killing disease. "Most...

By OUT DOORS JIM MORRIS That dreaded fish disease VHS (viral hemorrhagic septicemia) has been found again, this time at Clearfork Reservoir, near Mansfield, detected while doing routine tests on muskellunge. This doesn't mean you will start seeing dead muskies floating all over the lake. In fact, they say if it weren't for the tests of ovarian fluid in the sampling of fish, it's not likely the disease would be detected. At one time, all muskie eggs put into Ohio...

A deadly fish disease has been confirmed in yellow perch in Lake Michigan, Wisconsin environmental officials report. Viral hemorrhagic septicemia was detected in yellow perch, a popular sport fish, a week after being found in the carcasses of round gobies washed up in South Milwaukee, The Milwaukee Journal Sentinel reports. The disease, first recorded in the Great Lakes three years ago, is found in many species of freshwater fish but is not harmful to humans. Randy Schumacher, a regional...

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...
