Understanding the Spawning Behavior of Lake Whitefish: A Collaborative Study

Lake whitefish, or Dikameg, plays a crucial role in both their ecosystem and the cultural heritage of the Saugeen Ojibway Nation. However, much remains unknown about their spawning behavior. In an effort to shed light on this, scientists from Trent University, the Ministry of Natural Resources and Forestry, and the Saugeen Ojibway Nation collaborated on a groundbreaking study.

Utilizing advanced tracking technology, they monitored 50 tagged whitefish at the Port Elgin (Firehouse) shoal in Georgian Bay, Lake Huron. Their findings revealed fascinating patterns: whitefish arrive at the spawning grounds in a distinct sequence, stay for about a week, and then depart. Typically, males are the first to arrive, and the fish move to shallower waters at night, retreating to deeper areas during the day. Interestingly, females swim faster during daylight hours, while males are more active at night. Throughout the spawning season, whitefish transition from deeper to shallower waters.

This research provides invaluable insights into the timing and locations of whitefish spawning, crucial for conservation efforts to ensure the species' future sustainability. To find out more visit: https://www.limnology-journal.org/articles/limn/full_html/2024/01/limn240009/limn240009.html
