Store description excerpt
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. ■ 567 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. 534 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. 258 of those species also carry full fishing data — season, method, rig and eating notes where appropriate. ■ 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 Sixteen methods, including sabiki, float fishing, surf casting, eging, jigging, live-bait fishing, freshwater lure fishing and stream bait fishing. Each one lists its difficulty, the shores it suits, who it suits, and the tackle you need with an indicative price range. Eight kinds of place cover the coast, rivers and lakes. ■ 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 — pufferfish handling requirements vary by prefecture; never prepare a self-caught pufferfish as an amateur. ■ 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: rules and access conditions vary by place and time. Check current local information before fishing. ■ Works offline The guide data and the photographs are bundled with the app. Search and browse with no connection at all. ■ Nine languages Japanese, English, Simplified Chinese, Traditional Chinese, Korean, Spanish, French, German and Brazilian Portuguese. Not just the interface — the fish descriptions, fishing notes and safety warnings are translated too. Japanese, English and scientific names are shown side by side, which helps if you are fishing in Japan from abroad, or pointing at something in a tackle shop and asking what it is. Note: a fish is shown under its name in your l
