Perhaps one of the most interesting fish in the CRSP’s portfolio is male pallid sturgeon PLS08-006.  This individual was originally implanted with a telemetry device in the spring of 2008 and has since been located on 93 occasions between river … Continue reading →

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 … Continue reading →

  Telemetry crews tracked female pallid sturgeon PLS11-007 to her spawning location (see previous post An Early Spawning Recorded) on March 30 and 31.  Additional crews were deployed April 3 in an effort to confirm a successful spawning at this … Continue reading →

The upstream migration of female pallid sturgeon PLS09-011 continued on April 18th and 19th (see previous posts Going, going…).  However, she disappeared for the next few days until being located more than 50 miles downriver from her previous location on … Continue reading →

Female pallid sturgeon PLS09-011 was originally implanted with telemetry devices in the fall of 2009 as a non-reproductive female. She was targeted for recapture and determined to be in reproductive condition in March, 2012 (see the previous post Meet the … Continue reading →
