Description
Guillaume Grosbois and three co-authors published a 2025 study of kettle lakes that sit on eskers in eastern Canada. These small lakes formed as glaciers retreated and often have no stream links to other waters. The team asked how the presence of fish shapes waterbirds and small water animals in the lakes, and compared them with the region's more common clay-belt lakes.
Water chemistry differed sharply between the two lake types, but not between esker lakes with and without fish. Several bird species fared worse where fish were present, and the small animal communities also shifted with fish. Fish numbers grew where human disturbance near shore was higher. The authors argue that fishless esker lakes hold rare value and need protection.
