Bull Trout (Salvelinus confluentus)

Bull trout are members of the salmon family, in a group known as the char. Char are distributed farther north than any other group of freshwater fish exc

They can grow to more than 20 pounds in lake environments. Char are distinguished from trout and salmon by the absence of teeth in the roof of the mouth, presence of light colored spots on a dark background, absence of spots on the dorsal fin, small scales and differences in the structure of their skeleton.

There is a fundamental reason why we look at the sky with wonder and longing—for the same reason that we stand, hour after hour, gazing at the distant swell of the open ocean. There is something like an ancient wisdom, encoded and tucked away in our DNA, that knows its point of origin as surely as a salmonid knows its creek. Intellectually, we may not want to return there, but the genes know, and long for their origins—their home in the salty depths. But if the seas are our immediate source, the penultimate source is certainly the heavens…The spectacular truth is—and this is something that your DNA has known all along—the very atoms of your body—the iron, calcium, phosphorus, carbon, nitrogen, oxygen, and on and on—were initially forged in long-dead stars. This is why, when you stand outside under a moonless, country sky, you feel some ineffable tugging at your innards. We are star stuff. Keep looking up.

Long-finned Charr (Salvethymus svetovidovi)

…A species of salmonid fish that is endemic to Elgygytgyn Lake in Eastern Siberia. Must is unknown about S. svetovidovi’s biology but it is known to occur in deep waters close to the bottom of the lake. Due to its limited habitat S. svetovidovi is currently listed as vulnerable and likely faces threats from pollution as well.

From our good friends and partners at Mongolia River Outfitters comes this beast of a Taimen, the largest salmonid on the planet and one of the premier fly rod game fish there is with crazy aggressive takes on surface flies and like most other species they are found in some beautiful places!

It Takes a Village to Raise a Salmon: Multilingual Monday, Partnership Edition

Partnerships are the Heart of Conservation

The African proverb states that “it takes a village to raise a child.”  The same can be said for restoring the environment.  In the Nisqually Valley of Washington, a group of people are trying to do just that.  Federal state agencies, the Nisqually Indian Tribe and private groups have been working together for more than a decade to restore an area of Ohop Creek (a tributary to the Nisqually River) back to its salmon-producing days.

The valley and creek were altered in the 1800s by people for farming and pastures.  Ohop Creek was rechanneled, changing the direction of the creek and altering its salmon- and trout-friendly habitats.  Because of both the historical and biological connections, specialists such as Rich Carlson, U.S. Fish and Wildlife Service restoration ecologist, and Christopher Ellings, Nisqually Indian Salmon Recovery Manager, work together to find creative solutions to restore the land.

Brown Trout

Salmo trutta

Salmo means salmon, while trutta translates to trout.

Family: Salmonidae (Salmonids)

Fun Fact: “Social hierarchies are also established when mating does not occur. Males have a personal territory that they will defend year round. Male fighting techniques include quivering, charging, ramming, biting, and chasing. Males quiver parallel to one another in an attempt to drive away their competition. Charging involves opening the mouth and swimming very quickly at another male to intimidate and drive competition off. Ramming is much like charging, but involves physical contact with each other. A male will bite at another male’s fins in order to show his dominance. Once a male submits, the dominant male will chase the subordinate male for a few seconds to truly confirm that he is the winner.” (ADW)

Habitat: They are endemic to freshwater ways and oceans around Europe (as far east as the Ural Mountains), and the Mediterranean Sea. They are invasive in the United States, Asia, Australia, New Zealand, southern Africa, and South America.

Ecosystem Role: They help keep fish, aquatic invertebrate, and crustacean populations in check. They provide food for humans, carnivorous mammals (such as, otters, minks, and seals), birds that fish (like herons or kingfishers), and other fish (like cod). 

Postdoc: USDA_WestVirginia.FishGenomics
The U.S. Department of Agriculture (USDA), Agricultural Research Service (ARS), North Atlantic Area is seeking highly qualified candidate for a temporary full-time Postdoctoral Research Associate (Research Molecular Biologist/ Geneticist), for the National Center for Cool and Cold Water Aquaculture Research Facility in Leetown, West Virginia. Salary range of $63,091 to $82,019. This position affords the opportunity tobe a team member in the research project entitled $B!H(BIntegrated Research Approaches for Improving Production Efficiency in Salmonids$B!I(B, located within the USDA-ARS National Center for Cool and Cold Water Aquaculture (NCCCWA), Leetown, WV, and will conduct genome mapping and molecular genetics studies to identify DNA sequence variation in positional candidate genes and regulatory elements affecting bacterial cold water disease (BCWD) resistance in rainbow trout. The specific research assignment will utilize QTL mapping and functional genomics data from previous studies at the NCCCWA and will involve gene discovery through the implementation of next generation DNA and RNA sequencing technologies combined with Genome-Wide-Association-Studies (GWAS). The successful candidate will participate as a multi-disciplinary team member in the selection and development of appropriate methodologies and experimental procedures. Qualification Requirements: A Ph.D. in molecular biology, physiology, genetics, life science or a related field is required. Knowledge and experience in DNA sequencing, gene cloning, PCR, and gene expression is desirable as well as professional knowledge in Fish Biology, Fish Genetics, Molecular Biology, Genomics, Immunology and/or Aquaculture. Experience with aquaculture or animal production would be an asset. Strong computer programming and analytical skills are valuable. You must meet all requirements for the position including completion of the Ph.D. prior to entrance on duty. Citizenship Restrictions Apply. Please send resume/CV to: Dr. Yniv Palti.
