[env-trinity] CBB: Treating anxious outmigrating salmon

[Paul Catanese]

The racism card. Heard it all. Fact are facts. The river is on serious peril.keep ignoring the facts on the ground. The coho are virtually extinct and all other species at all time lows. I I'm not intimidated by your insult.

That comment either stems from ignorance or border-line racism.  If the former, I’d be happy to educate you regarding how harvest management works in the Klamath Basin, if the latter, please keep such comments to yourself or some other forum - this list-server is typically a good source of information without having to deal with such biases directed at people of the basin.

Agree. Looks at the dwindling fish population in the trinity and all the nets at the mouth. I'd be really nervous.

If I was a fish and I knew that my best friend was a fisherman I'd be pretty anxious too.

Study Treats Migrating Salmon With Anxiety Medication, Says Limits Fear Of The Unknown Downstream
Posted on Friday, December 09, 2016 (PST)

Current research from Umeå University in Sweden shows that the young salmon's desire to migrate to the sea can partly be limited by anxiety.

Researchers have long tried to understand what factors affect the young salmon's decision to migrate out to sea. Previous studies have indicated that environmental factors such as temperature, light conditions and water flow may play an important role. However, large parts of the within species variation in fish migration remains unexplained.

A study http://www.nature.com/articles/ncomms13460 from Umeå University, published in the journal Nature Communications, now shows that the salmon's inclination to migrate is partly limited by its fear of the unknown downstream.

"By treating salmon with an anxiolytic drug, anxiety medication that is, we artificially changed the migration intensity of the salmon where treated salmon travelled further and faster than untreated salmon," says Gustav Hellström, one of the researchers behind the study.

The research team studied how salmon migration was affected both in a lab, where salmon migrated in a large artificial stream, and in a natural stream outside of Umeå in Northern Sweden. In both environments, researchers found that salmon treated with anxiety medication migrated nearly twice as fast as salmon who had not been subjected to treatment.

Several billion animals migrate yearly and the study results show that anxiety limits migration intensity, is not only important for understanding salmon migration but also for understanding migration in general, says the study.

The study also has an ecotoxicological dimension as the quantity of medication that the salmon was exposed to was low - in fact so low that it measured lower than that found in wastewater in certain areas.

"Even though salmon in Northern Sweden live in river-systems low to moderately affected by contaminated wastewater it is not very likely that exposure to anxiety medication is an environmental issue for these populations right now. However, given the low dose used in the study we cannot rule out that, with increasing human population and medical use, this might become a problem in the near future" says Hellström.
