Blue Sucker (Cycleptus elongatus) -

 Water Diversion and Endangered Species




In 1998 and again in 2004, Biotactic, Inc. was retained for a telemetric assessment of blue sucker (Cycleptus elongatus) spawning behavior and habitat use as part of a water diversion environmental assessment. This work was carried out in association with Espey-Huston and Associates, and Bio-West Inc., Austin, Texas. Forty blue suckers were caught by boat electrofishing in riffles, implanted with transmitters and released back into the Lower Colorado River, between Austin and the Gulf of Mexico. Thirty blue suckers were monitored with fixed receiving stations, boat tracking and airplane tracking until the end of 2007.

Beginning in October 2012, we facilitated the set-up of a year long combined radio and acoustic telemetry project on the Sabine River between Texas and Louisiana (with Bio-West, Austin).  For this project seven underwater receivers as well as mobile boat and aircraft tracking are being used to monitor and track the movement and habitat utilization of 56 CART and radio-tagged blue suckers, including the first juvenile fish ever radio-tagged and tracked.
