The species library
Forty-eight species across coarse, sea and fly. Each entry carries the habitat, the time of day they feed, the baits and tactics that work, the tackle that suits, welfare thresholds in warm water, and the 2026 rules where they apply.
Written for UK and Ireland waters, and generated from the same data the app uses on the bank. The 2026 rules are here.
