My Scientific Name
By the Numbers
If I am a female, I can grow up to 4 feet in length and weigh up to 9 pounds. Males only reach 1.5 feet in length. Females also are lighter in color, with smaller eyes and higher fins than males.
How to Identify Me
When I am an adult my coloring is olive-green or brown on my back and pale green or yellow on my sides and underneath. I have long dorsal and anal fins that are joined to my tail fin with two small pectoral fins behind my gills.
Why I Matter and What's Been Happening
My species once made up over a quarter of the total fish found in Atlantic coastal streams. Dams have prevented us from reaching our feeding grounds, and have reduced the amount of good habitat for us to live in the river. And when we migrate downstream to return to the ocean, we can get caught, and sometimes even die, in turbines at hydroelectric facilities, where electricity is generated using river water.
Biologists are studying my downstream migration to see if large dams that are used to generate electricity are having an effect on my journey. The biologists are also working on ways to safely move us up and downstream of dams.
