In 1998 and again in 2004, Biotactic, Inc. was retained for a telemetric assessment of blue sucker (Cycleptus elongatus) spawning behaviour 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 will be monitored with fixed receiving stations, boat tracking and airplane tracking until the end of 2007.

In December 2004 and December 2005, Biotactic assisted Bio-West (Utah) with the set-up  of a biotelemetry project (including capture, surgery, preliminary tracking) of federally endangered razorback suckers (Xyrauchen taxanus) in Lake Mead, Nevada.  This project is designed to identify perhaps some of the last remaining previously unknown areas in the world where wild razorback sucker populations successfully reproduce. 

In 2006 we began a long-term endangered freshwater mussel monitoring program with the Department of Fisheries and Oceans Canada.  This project uses our BRAVO underwater monitoring network to transmit and record interactions between wavy-rayed lampmussels and obligate fish hosts in the Grand River, Ontario.  To learn more, CLICK HERE.
