Better Late than Never

A reproductive female pallid sturgeon was reeled in on a trotline near Columbia, MO on Friday, April 15. She was implanted with a telemetry transmitter and given the “name” PLS11-008.  She weighed 2.30 kg (5 lbs) and had a firm belly full of black eggs.  PLS11-008 has a coded wire tag indicating she was produced in a hatchery.  Genetic testing will contribute more information regarding her parents and hopefully lead us to the year she was born.

Upon making an incision in PLS11-008 in which to implant a telemetry transmitter, black eggs pushed to the surface. A few of the eggs were collected for analysis on how close she is to spawning.

PLS11-009, a reproductive male, was captured 3 miles downstream of PLS11-008 on the same day.  Caught  in a gill net, PLS11-009 weighed 2.7 kg (almost 6 lbs) and has no hatchery markings.  A genetic sample was taken to identify if he truly is a wild pallid sturgeon.

With water temperatures and river levels rising, the focus is now changing from fishing to tracking.

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.
