Understanding Bass Movements in Big Waterbodies

Understanding Bass Movements in Big Waterbodies

In this post, we are providing some photos from another aspect of our research on bass in the Eastern Basin of Lake Ontario. This ongoing study is using “state of the art” biotelemetry technology to provide additional insights into the natural movements of bass in this system, as well as their ability to navigate back to their home ranges when they are displaced in tournaments. If you would like to know more about this, further details are provided below…

In this large scale study, we've created a series of gates by placing receivers at strategic locations between Trenton and Amherst Island (see photo). We have also surgically implanted transmitters into groups of Smallmouth Bass and Largemouth Bass (see photo), so that we can monitor their movements past the gates in this system (the receivers will detect individual fish when they pass the gate). Some of the fish have been released close to where they were caught (control groups). Others have been caught in one area and released at a distant site (displaced groups). In order to create an appropriate control group of Smallmouth Bass, we have also added a few receivers at the Main Duck Islands and caught and released another group of fish there which have been implanted with transmitters. All of the fish in these experiments have been marked with 2 external pink tags (see photos) and we ask that you please contact us if you happen to catch one.

Our next post, will provide some very interesting early results from this study (MSc thesis project Rachael Hornsby).

Pink tags indicate the presence of an internal acoustic transmitter.

Tags are labelled Queen's University, have a unique ID number and contact information including phone number and website.

Please contact us if you catch a bass with pink floy tags.

implanted in the body cavity of
