Harbingers of Spawning

Red Buds blooming … check.
Cottonwood leaves out … check.
Water temperatures rising … YIKES!
Past research has shown that reproductive pallid sturgeon migrate upstream when water temperatures are around 15°C (59°F) and they spawn when water temperatures are around 18°C (64°F).   The USGS streamgage at Hermann, MO, reports water temperatures approaching 14°C on April 11.  With temperatures on the rise, field crews are feeling the pressure to catch a reproductive female in the lower study study section.

About Emily Pherigo

Emily is no longer with the Comprehensive Sturgeon Research Project. When she was here, she was a biologist contracted to the Comprehensive Sturgeon Research Project. Most of her time was spent at a computer performing QA/QC on data or updating figures and graphs most used by Aaron DeLonay. However, she occasionally made it to the river, where she enjoyed seeing pallid sturgeon and was reminded why she entered the natural resources field.
