Project Details

The role of mating pheromones in lake trout remains poorly understood due to a lack of information on their source and identity. Researchers at Michigan State University investigated the chemical identities of male and female pheromones that may guide reproduction in lake trout. They first reviewed the literature to identify and compare the approaches taken to identify pheromones in fish. Second, they integrated these approaches to identify several candidate pheromones in lake trout. Chemical analyses of one component indicated it is released at high rates by males but not females, but the activity level of fish exposed to this component remained low, so insufficient evidence exists to identify it as a reproductive cue.
