If you've ever assumed that getting a German fishing licence is just a matter of filling out a form and paying a fee, prepare to be surprised. The Fischerprüfung — Germany's fishing licence exam — is a proper written test covering biology, ecology, law, and equipment. Most states require you to pass it before you can legally cast a line in German waters.
It's not easy. The pass rate varies by state, but plenty of candidates fail on their first attempt — usually because they underestimated the scope. Fish species identification alone trips up more candidates than any other single topic.
This guide covers everything you need to know: the exam format, what's actually tested, the most common fail reasons, and a study strategy that works.
The Exam Format
The Fischerprüfung is administered at the state (Bundesland) level, which means the exact format varies — but the structure is broadly consistent across Germany. Most states use a written multiple-choice format with around 60 questions. You typically need to answer roughly 75% correctly to pass (the exact threshold varies: some states use 45/60, others 40/60, so check your state's rules before you sit).
The exam is supervised, taken in person at a designated testing centre, and usually held several times per year. You register through your local Fischereibehörde or Anglerverband. Entry fees are modest — typically €30–60 — but some states charge more for the exam package including the fishing licence itself.
There's no time pressure that most candidates find problematic. Two hours for 60 questions is usually enough. The difficulty is knowledge, not speed.
The 6 Exam Topics
The official curriculum is divided into six subject areas. Here's what each covers — and how hard each actually is in practice.
1. Fischkunde (Fish Biology)
This is the largest and most difficult topic for most candidates. You need to be able to identify 20+ freshwater fish species — not just name them, but recognise them visually by body shape, colouration, fin placement, and scale patterns. Carp, pike, perch, bream, zander, tench, roach, rudd, bleak, gudgeon, barbel, chub, dace, trout (brown and rainbow), grayling, eel, wels catfish — the list goes on.
Beyond species ID, you'll be tested on fish anatomy, reproductive biology (spawning seasons matter for closed seasons), growth rates, and habitat preferences. Spawning months are tested directly in law questions too, so knowing that pike spawn in early spring and trout in autumn pays double dividends.
2. Gewässerkunde & Ökologie (Water Ecology)
More interesting than it sounds, and more important than most candidates expect. This covers river zonation (the Forellenregion, Äschenregion, Barbenregion, Brassenregion system), water quality indicators, oxygen levels, pH, and how pollution affects fish populations. You'll also see questions on the food chain — what eats what — and invasive species.
The ecology questions tend to reward genuine understanding over rote memorisation. If you understand why certain fish appear in certain water types, you can work out answers rather than just recall them.
3. Gerätekunde (Fishing Equipment and Techniques)
Hooks, lines, rods, nets, landing nets, keep nets — you need to know the German names for equipment and the legal requirements around it. Some techniques are banned entirely (electrofishing without permit, certain net sizes). You'll also see questions about legal bait species and minimum mesh sizes for nets.
This is the most practical topic and the easiest for anyone who has fished before. If you've never fished, spend extra time here.
4. Fischereirecht (Fishing Law)
One of the more tedious topics — but you cannot skip it. Law questions cover: minimum catch sizes (Mindestmaße) for protected species, closed seasons (Schonzeiten) by species, daily bag limits, licensing requirements, what constitutes poaching (Fischerei ohne Erlaubnis), obligations when you catch undersized fish, and regulations around fishing near protected zones.
Critical caveat: fishing law in Germany is partly federal and partly state law. The exam in your state will test your state's specific rules. Minimum sizes for pike, for example, differ between Bavaria, Brandenburg, and North Rhine-Westphalia. Use study materials specifically designed for your Bundesland.
5. Fischkrankheiten (Fish Diseases)
This topic is primarily memorisation. You need to know the major notifiable fish diseases — KHV (Koi Herpesvirus), VHS (Viral Haemorrhagic Septicaemia), IHN (Infectious Haematopoietic Necrosis), spring viraemia — plus common parasites (Argulus, Ichthyophthirius, Gyrodactylus) and fungal infections. You'll be tested on symptoms, transmission routes, and your legal obligations if you find diseased or dead fish.
The good news: there are only around 10–15 diseases you really need to know. A flashcard set works well here.
6. Naturschutz (Nature Conservation)
Conservation law, protected species (not just fish — also birds, amphibians, plants that inhabit fishing waters), and obligations to report environmental damage. You'll need to know which bird species are protected and cannot be disturbed near nesting sites, which plants you cannot remove from riverbanks, and what "catch and release" rules look like legally in different states.
This topic overlaps with fishing law but comes from a different legal framework (Bundesnaturschutzgesetz). Keep the two separate in your notes.
The Most Common Fail Reason: Fish Species Identification
Ask anyone who has failed the Fischerprüfung what caught them out, and most will say the same thing: they couldn't tell a roach from a rudd, or confused a bream with a silver bream, or misidentified a young zander as a perch.
Fish species ID is hard because many German freshwater species look similar to the untrained eye, especially juveniles. The exam typically shows photographs or illustrations and asks you to name the species — or asks you to match a description to a species. You cannot bluff your way through this with general biology knowledge.
The only approach that works: repeated visual practice. Flashcards with photos on one side and the species name on the other. Cover every species in your state's official question catalogue. Do this until identification is reflexive, not effortful.
Study Strategy That Works
Based on the difficulty weighting of the topics, here's the order I'd recommend:
Week 1–2: Fish species identification. Start here because it takes the longest to learn and cannot be crammed. Get a visual flashcard set. Go through all species daily. Focus on the distinguishing features — lateral line scale count, fin ray counts, colouration patterns. For similar-looking pairs (roach/rudd, bream/silver bream, trout/salmon parr), learn the single key difference that separates them.
Week 3: Fishing law. This is the most state-specific part of the exam. Get the official question catalogue from your state's Fischereiverband. Work through every law question. Make a table of minimum sizes and closed seasons — these come up directly. Don't rely on a generic national resource here.
Week 4: Ecology + diseases. Water ecology rewards understanding, so read through a good primer and make sure you understand the river zonation model. Fish diseases are memorisation — one session with good flashcards, repeated twice.
Final week: Mock tests. Do full timed runs through the official question catalogue. Most state Fischereiverbände publish the complete question pool — the actual exam draws from it. If you can consistently score above 80% on mock tests, you're ready.
Equipment and conservation can be studied alongside everything else — they're smaller topics and tend to require less dedicated time.
Why I Built the Fischerprüfung App
When I was preparing for the exam, I couldn't find a study app that covered the full official German state question catalogues in a clean, usable format. Most resources were PDFs, outdated websites, or generic apps that didn't match what actually appeared in the exam.
So I built one. The Fischerprüfung app for iOS covers the official question catalogue with all six topic areas, includes photo-based species identification flashcards, and lets you run timed mock tests in exam mode. It's free to download.
The app is built in SwiftUI and runs on iPhone and iPad. It's the study tool I wish I'd had when I was preparing.
