Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-11-03T00:00:00Z
We collected eggs from female Lake Trout during the fall of 2015 to assess the relationship between female Lake Trout size and the number of eggs produced by individual fish. All data were collected between 7 September and 8 October, 2015. We collected 325 Lake Trout, however, only 44 were females that had eggs held together in a skein. We found a positive correlation between female Lake trout size (length and weight) and the number of eggs produced per female.
