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...

Inhibition of myostatin results in fish with 'six-pack abs' A 10-year effort by a University of Rhode Island scientist to develop transgenic rainbow trout with enhanced muscle growth has yielded fish with what have been described as six-pack abs and muscular shoulders that could provide a boost to the commercial aquaculture industry. Terry Bradley, a URI professor of fisheries and aquaculture, said his research into the inhibition of myostatin, a protein that slows muscle growth, has obtained...

NOVATO, Calif., Nov. 9 /PRNewswire/ -- Amazingly, there are still places in the Bay Area and Central Valley where keen-eyed observers can witness one of nature's miracles: wild salmon spawning. The Bay Institute has just published an updated map and calendar of top local viewing spots and information on the best seasons to see salmon in the wild. These free brochures are available at Aquarium of the Bay, where a new poster exhibit highlights the life cycle of these extraordinary fish....

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...

Trout are better models for cancer research than mice or rats, a leading researcher at Oregon State University said. George Bailey helped found the university's world-class trout research center, which recently completed a study of the effects on tissue of carcinogenic Dibutyl phthalate, used in adhesives, plastics and ink, The (Portland) Oregonian reported Tuesday. Three decades of aquatic study convinced Bailey, 68, that trout are cheaper to raise and care for than rodents, and have...

Steelhead trout that are originally bred in hatcheries are so genetically impaired that, even if they survive and reproduce in the wild, their offspring will also be significantly less successful at reproducing, according to a new study published today by researchers from Oregon State University.The poor reproductive fitness "“ the ability to survive and reproduce "“ of the wild-born offspring of hatchery fish means that adding hatchery fish to wild populations may ultimately be...

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...

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...
