Temperature Loggers / Monitoring Water Temperature
Bay Of Quinte, Lake Ontario, St. Lawrence River

Starting in the early spring electronic temperature loggers are placed in various locations throughout the Bay Of Quinte, Lake Ontario and the St. Lawrence River. Some logger locations are not visible while others can be clearly noticed by a Red floating buoy. The buoy will be identified with "Queen's University Biology Dept." marked on them. If you happen to see one of our buoys please do not move it since we need to return from time to time and be able to collect the temperature data. Later in the year we return once more to retrieve the buoy/logger. If it has been removed or relocated we will not be able to locate it and the valuable data and equipment will be lost. There are a number of interesting research projects that will utilize the temperature data collected including the study of Small and Large Mouth Bass spawning in these different areas

Fish Tagging
Bay Of Quinte, Lake Ontario, St. Lawrence River

The Freshwater Fisheries Conservation Lab has been working very hard since 2010 tagging both smallmouth and largemouth bass. We are studying the movements and relocation of fish after being caught and released. We all know that catch and release works, this research gives us more valuable data on how the fish react after being released and where they travel to.

Please if you catch or have caught a bass with a yellow or pink tag it is important and very much appreciated if you report the tag number, general location and if it was released. Please note that we do not want you to tell us the exact location or provide us with gps way points of where the fish was caught, only the zone where you caught the fish and if it was released again or taken
Please go to to report the tag number or call  613-533-6143 and leave us a message. (Remember to leave a call back number THANKS!)

Study of Bass Spawning

St. Lawrence River, Lake Ontario
Starting in early spring bass spawning areas are being studied by swimming and snorkeling over and around nesting sites. Along with temperature logging data other information is gathered such as the stage and date of the spawn (eggs,  bottom fry, swim up fry) as well as the presence of gobies and other predators.

DNA Research
Lake Ontario & St. Lawrence River Smallmouth and Largemouth Bass
DNA approach provides valuable insights into Lake Ontario bass diets and genetics.

These days, our lab is also using DNA research improve our understanding of the prey consumed by Bass in Lake Ontario and the St. Lawrence River as well as  genetic variables in Smallmouth bass from different areas.

Freshwater Aquaculture
Queen's University Biology Dept.

With the popularity of fish as a food source for humans, the ever increasing demand has demonstrated that more information is needed to safely and economically learn how to farm freshwater species here in Canada. The Freshwater Fisheries Conservation Lab operates a Tilapia recirculating aquaculture system and will be adding other species like Brook Trout and Walleye in the near future.

BIOTELEMETRY Understanding Bass Movements in Big Waterbodies

Eastern Basin of Lake Ontario, Bay of Quinte

This ongoing study is using “state of the art” biotelemetry technology to provide additional insights into the natural movements of bass, as well as their ability to navigate back to their home ranges when they are displaced in tournaments.

Fish Ageing
Ever wonder how old the fish are that you are catching? This has been an important aspect of the research that we have been doing on various fish populations. Fish can be aged by counting the annual growth rings in several hard structures (scales, otoliths, dorsal spines), but otoliths are the best structure for older fish.
