Temperatures at Node 10 are now being archived along with fish count data.


July 5, 2011 - Node 9 and Node 10 Archives updated, Node 11 undergoing testing


New footage of fish and non-fish activity at Node 9 and Node 10 is available for viewing. Our newest unit, Node 11 is currently undergoing testing in preparation for deployment.

Conditions have finally cooperated in the Rock River and the new self-cleaning sensor-head for
Node 6 was successfully installed, tested and is currently onlineThanks to everyone who emailed for your patience.


May 17, 2011 - Node 1 Temperature Data, Node 10 Archive updated


Data loggers located at Node 1 have been continuously recording water temperatures and data from 2010 and 2011 are now available. Video archive and fish counts at Node 10 are continually being updated.


May 4, 2011 - Node 1 Archive updated


Node 1 camera has finally been cleaned (requiring a total soaker). New video footage of fish and other wildlife activity from Node 1 has been archived and is now available for viewing.  We are very impressed with our self-cleaning systems (Node 9 and Node 10).  Node 3 has lots of interesting centrarchid activity with fish preparing to nest and spawn.


April 29, 2011 - Node 9 Archive updated, London Free Press


Video footage of fish and other wildlife activity from Node 9 has been archived and is now available for viewing.


London Free Press has featured our report in an update to the status of the Springbank Dam in London. See other news articles featuring our work here.


April 28, 2011  - Monitoring Node 1 and the Grand River


Water levels in the Grand River are high and turbid and we are unable to clean our Node 1 Camera so image quality is poor (it is not one of our self-cleaning models).  More rain and stormy weather is on the way.  A fish trap in the Thornbury Fishway (Node 10) was installed on April 27 for the collection of trout eggs (for a hatchery) and removed April 28.


April 25, 2011 - New blog, network changes


Welcome to Biotactic's new blog, providing up to date information on our activities. Our latest Node 10, located in a fishway in Thornbury, Ontario is now fully operational and is being archived here. As part of ongoing research, fish utilizing the fishway are being counted.


Node 4 and Node 5 have completed their scheduled data collection and are being relocated, other live feeds can be viewed here.


Node 6 will be online soon pending installation of its new self-cleaning system by the Wisconsin Department of Natural Resources (WDNR).
