What did I catch?
Answer a few quick questions about your fish and this narrows 140 species down to the most likely matches. It is a guide, not a positive ID, so it shows you a shortlist of candidates to compare, never a single guaranteed answer. Skip any question you are unsure about.
This tool matches on broad, visible features, so colours that shift with age, season and water, and species that look alike, mean the shortlist is a starting point, not proof. Always confirm a fish against its full profile and a good photo before you rely on it, especially for anything you plan to keep - size and species rules are set by your state. Check the licence and regulations for where you fish, and release anything you cannot confidently identify.
