Blue Sucker movement and population demographics in rivers of the southern plains

Joey Dyer sampling Blue Suckers.


September 2014 - August 2018


Globally, human alterations to river systems have resulted in the decline of migratory large-river fish populations. The Red River basin is home to several migratory large-river fishes that are considered species of conservation concern. This project focuses on the movement patterns and population dynamics of Blue Suckers in the lower Red River basin (downriver of Lake Texoma).
