Hatcheries Change Salmon Genetics After A Single Generation
2011-12-20 10:28:33

The impact of hatcheries on salmon is so profound that in just one generation traits are selected that allow fish to survive and prosper in the hatchery environment, at the cost of their ability to thrive and reproduce in a wild environment. These findings, published this week in Proceedings of the National Academy of Sciences, show a speed of evolution and natural selection that surprised researchers. They confirmed that a primary impact of hatcheries is a change in fish genetics, as...

University of Oregon's RAD technology opens route to see important genetic markers in rainbow trout Two distinct populations of rainbow trout -- one in Alaska, the other in Idaho -- share a genetic trait that could have huge implications for fisheries conservation and management, an eight-member research team reports. The common trait is a similar rapid rate of development that has allowed these different salmomid subspecies to adapt to their native rivers in Alaska and Idaho. The...

SACRAMENTO, Calif., Nov. 9, 2011 /PRNewswire/ -- California Trout and Trout Unlimited today launched an outreach campaign to advocate for a science-based approach to managing the Central Valley's flood protection system including connected floodplains required for salmon recovery. The groups came together in response to FloodSAFE, a California Department of Water Resources (DWR) initiative designed to improve the state's integrated flood management plan. FloodSAFE is a result of 2007...

PORTLAND, Ore., Aug. 9, 2011 /PRNewswire-USNewswire/ -- Over 1,000 American businesses have asked President Obama for decisive change in the government's failed policy to restore endangered wild salmon and steelhead in the Columbia and Snake Rivers. The request comes in a letter released today, following U.S. District Judge James Redden ruling on August 2, 2011 finding the administration's current salmon plan illegal. Salmon are a mainstay of economies and jobs for the entire west coast....

Fishing, conservation groups call for solutions table on salmon crisis PORTLAND, Ore., Aug. 2, 2011 /PRNewswire-USNewswire/ -- U.S. District Court Judge James Redden ruled today that the National Oceanic and Atmospheric Administration (NOAA) Fisheries Service failed for the third time in ten years to produce a legal and scientifically adequate plan to protect imperiled Columbia-Snake River salmon from extinction. The harm to these species has been largely caused by operation of the...

PORTLAND, Ore., Feb. 16, 2011 /PRNewswire/ -- A letter from William Stelle, Jr. - the Regional Administrator of the National Oceanic and Atmospheric Administration, National Marine Fisheries Service - has cleared the way for one of the region's most complex and significant clean up/remediation projects along the Willamette River. The letter, known as a Biological Opinion [https://pcts.nmfs.noaa.gov/pls/pcts-pub/biop_results_detail?reg_inclause_in=('NWR')&idin=122048], provides the...

Genetic research is showing that healthy steelhead runs in Pacific Northwest streams can depend heavily on the productivity of their stay-at-home counterparts, rainbow trout. Steelhead and rainbow trout look different, grow differently, and one heads off to sea while the other never leaves home. But the life histories and reproductive health of wild trout and steelhead are tightly linked and interdependent, more so than has been appreciated, a new Oregon State University study concludes. The...

Fast-growing farm-raised salmon and trout that are sterile can now be produced using a method developed by Agricultural Research Service (ARS) scientists. Blocking reproduction can enhance growth, and is important for fish being reared in situations where reproduction is undesirable. The method allows researchers to more efficiently and reliably produce fish that have three sets of chromosomes, instead of the usual two sets. Fish with the extra set of chromosomes can't reproduce, so the...

What do a trout, sea anemone, rooster, fly and man have in common? Just as styles in sexy clothes or fashion change from year to year and culture to culture, "sexy" genes, or genes specific to sex, also change rapidly. But there is one sex-specific gene so vital, its function has remained unaltered throughout evolution and is found in almost all animals, according to new research from Northwestern University Feinberg School of Medicine. The gene, called Boule, is responsible for sperm...

PACIFIC GROVE, Calif., July 8 /PRNewswire-FirstCall/ -- California American Water announced today its recent delivery of a $1.1-million payment to the California Department of Fish and Game to fund National Oceanic Atmospheric Administration Fisheries that benefit habitat for threatened steelhead trout in the Carmel River. The payment is the company's second annual contribution designed to fund what will ultimately be an $11.2-million environmental grant program administered by the...

Brown Trout, Salmo trutta
2013-10-15 12:46:40

The Brown Trout (Salmo trutta) is originally a European species of salmonid fish. It includes both purely freshwater populations, referred to Salmo trutta morpha fario and S. trutta morpha lacustris, and anadromous forms referred to as the sea trout, S. trutta morpha trutta. The latter migrates to the oceans for the majority of its life and returns to freshwater only to spawn. The specific handle trutta comes from the Latin trutta, meaning, literally, “trout”. The lacustrine morph of...

Lake Trout, Salvelinus namaycush
2009-02-16 20:21:04

The Lake Trout (Salvelinus namaycush) is a species of freshwater char that is found mainly in lakes of Canada, Alaska, and the northern United States. They have been introduced into many other parts of the world including Europe, South America and some parts of Asia. In Canada, about 25% of the Lake Trout population is found in Ontario. However, only 1% of Ontario's lakes contain trout. The Lake Trout has been known to hybridize with Brook Trout, but such hybrids are almost always...

Golden Trout, Oncorhynchus mykiss aguabonita
2009-01-17 20:32:05

The Golden Trout (Oncorhynchus mykiss aguabonita) is a subspecies of the Rainbow Trout (Oncorhynchus mykiss). It is also known by the name California Golden Trout and is native to Golden Trout Creek, Volcano Creek and the South Fork Kern River in California. It is most likely found at elevations 10,000 feet above sea level. This subspecies is also commonly placed with other subspecies of rainbow trout known as redband trout. The Golden Trout has flanks with a red, horizontal band along the...

Redband Trout, Oncorhynchus
2007-12-18 14:20:49

Redband Trout is a fish name that may be a synonym for the rainbow trout, but is used more narrowly for two subspecies with well-defined geographical distributions in the United States: the Columbia River Redband trout, (Oncorhynchus mykiss gardenia), found in Montana, Washington and Idaho, and the Great Basin Redband trout, (Oncorhynchus mykiss newberrii), found in southeastern Oregon, and parts of California and Nevada. Both subspecies are popular game fishes. The redband trout is...

Trout is the common name given to a number of species of freshwater fish belonging to the salmon family (Salmonidae). All fish properly called trout are members of the subfamily Salmoninae, but the name is used for fish from all three genera in the subfamily: Salmo, which includes Atlantic species; Oncorhynchus, which includes Pacific species; and Salvelinus, which includes fish referred to as Char. Fish referred to as trout include: Genus Salmo Adriatic trout - Salmo...
