Re: {Tidal Potomac Fly Rodders} pharmaceuticals in our rivers

Charlie,

 

Awesome article. Thanks for sharing!

     

        I did a lot of research on that subject while I was at George Mason working on my biology degree. Pharmaceuticals in our rivers is a bigger issue than people realize. One of the major ones that was not mentioned in this article is estrogen. It comes from birth control medications and estrogen replacement therapy as well as other things and it can cause mutations in many fish, including bass. Estrogen disrupts the endocrine system and leads to the development of female sex organs and eggs in male fish. This has been recorded in bass on the Potomac. Rainbow trout have also been found in many locations with the same problem. To make it worse certain pesticides can mimic pharmaceutical drugs in the water as well. I would love to share one of the articles from the university but unfortunately the research database I get them from is password protected so links don't work. This is a good publicly available article you might be interested in though.

All:

 

Interesting article on the impact presription drugs ingested by humans have on fish after they survive our sewage treatment plants.

I have probably served a few fish a Guinness or two.
