Fresh Catch: Lake Trout Otolith Collection from Lake Ontario

FishAge.org has just added a new Lake Trout otolith collection from Lake Ontario—a complete set of sectioned, high-resolution images from known-age fish. Sourced from a study by Osborne et al. (2022), this validated dataset offers an important reference for improving age interpretation accuracy and consistency across labs. Explore the collection, review study findings on precision and bias in Lake Trout aging, and see how accessible, known-age material supports better training and quality control in fisheries research.
