River Sweep May 21 – 29, 2012

With spawning season coming to an end, Comprehensive Sturgeon Research Project (CSRP) researchers are beginning to focus more on extensive tracking efforts and less on tracking individuals to their spawning sites.  We have defined a “river sweep” as an attempt to search for telemetered pallid sturgeon in as much of the Missouri River as possible, from the Gavins Point Dam near Yankton, South Dakota to the confluence near St. Louis, Missouri.  CSRP biologists teamed up with the Nebraska Game and Parks Commission to search for as many telemetry tagged pallid sturgeon as possible from May 21 – 29. Crews searched the Missouri from river mile (RM) 753.5 above Sioux City, Iowa to the Missouri and Mississippi River confluence near St. Louis.  Forty-five fish, including two previously reproductive females, were located during this month’s river sweep (see Previous Posts Down the Wide Missouri and  Meet the Ladies of 2012).  PLS09-011 was found near her spawning location at RM 580.7 while PLS11-007 was located approximately 75 miles downstream of her spawning site.
