Science Pub - Gonads and Goiters: Stickleback Fish Health and Disease in the Deschutes River

Tuesday, February 20, 2018 5:30 PM - 7:30 PM

Stickleback fish are models for studies about the impact of pollution on animal and human health. Humans and stickleback share about 70 percent of known human disease-causing genes. Stickleback are considered a “canary in the coal mine” for river and lake health by researchers worldwide. Health effects of aquatic pollution on this small fish are a proxy for the health impacts of aquatic pollution on all vertebrates, including humans. 

Stickleback are abundant in the Deschutes River and also found in the John Day and Crooked Rivers. OSU-Cascades biologist Ann Petersen will share how some local populations of wild-caught stickleback demonstrate distinct types of organ and tissue abnormalities and disease, including reproductive abnormalities. These health problems are consistent with signs that at certain locations on the Deschutes, the fish have been exposed to steroids from livestock or human waste, pesticides, herbicides, pharmaceuticals, plastics or other endocrine disrupting chemicals. She’ll also share OSU-Cascades researchers' long-term plans to use the stickleback as a powerful biomonitoring tool to help maintain healthy waterways in Central Oregon.

Doors open at 5:30 p.m.
Presentation starts at 6:30 pm.
