What is biting out there, this month.

Tsurizukan is a field guide to the fish of Japan, searchable by season, by fishing method, by the kind of place you are standing on, and by name. Every feature works offline - on a breakwater or a boat with no signal.

[ Biting this month ] Open the app and the first thing you see is what is catchable this month, with the peak-season fish marked. Pick any month from January to December to compare.

[ 963 fish of Japan ] Search by Japanese name, kana, English name, scientific name or local name. "マダイ", "まだい", "madai" and "sea bream" all find the same fish. 866 species carry a photograph, sourced from Wikimedia Commons and similar CC-licensed material; author and licence are listed inside the app as the licences require. 30 of those species also carry full fishing data - season, method, rig and how to eat them. More are being added.

[ Season calendar ] Every detailed species shows a twelve-month calendar that separates the months it can be caught from its peak months, so you can tell the fish you travel for from the fish you simply run into.

[ Methods and tackle ] Ten methods: sabiki, chonage, float fishing, fukase, surf casting, hole fishing, eging, jigging, tairaba and live-bait fishing. Each one lists its difficulty, the shores it suits, who it suits, and the tackle you need with an indicative price range. Six kinds of place: breakwater, sandy beach, rocky shore, river mouth, boat and raft.

[ Dangerous fish ] Venomous spines, venomous bites, toxic flesh, sharp teeth - the fish you should not grab bare-handed, collected in one list and shown at the top of each species page, never collapsed. Note: the hazard and first-aid text is general reference information only. It is not a substitute for the judgement of a professional or a medical practitioner. If you are stung or bitten, or feel unwell, seek medical care. No preparation instructions are given for fish with toxic parts - handling pufferfish in Japan requires a licence.

[ Ten columns ] Etiquette on the water, the basics of safety, fishing permits and fishing rights, how to check closed seasons and size limits, beginner guides to sabiki / chonage / eging, three knots worth knowing, and how to dispatch and carry your catch. Sources are cited. Note: laws, fishery regulations and access rules differ by area and change over time. This app does not give legal advice. Always check the current rules for the water you are fishing.

[ Works offline ] The guide data and the photographs are bundled with the app. Search and browse with no connection at all.

[ Japanese and English ] Every screen is bilingual, and Japanese, English and scientific names are shown side by side - useful if you are fishing in Japan from abroad, or pointing at something in a tackle shop and asking what it is.
