Fish
Since the 1970s, water quality has improved dramatically. Fish from the Main can be consumed without concern. Nevertheless, there are significant challenges, including the structural deficits of the local river and fish protection. Fish can to this day not migrate upstream or downstream. Dams and weirs need to be heavily modified so that fish can migrate again.
Today, there are 34 fish species living in the Frankfurt Main! Every year, we examine the fish population using modern methods. After the mass occurrence of invasive gobies, which entered the Main via the Danube Canal, we can today evaluate that gobies are no longer the most common species. Instead, native fish such as roach and bleak are now predominant again. Predatory fish, especially pike-perch, are reproducing very successfully in the Frankfurt Main. For several years, pike have also been naturally reproducing again in the river. The river Main has an outstanding population of predatory fish.
The Frankfurt Main River has an outstanding population of predatory fish.
The main goal is the return of Atlantic salmon to the Main, which historically had one of the most impressive fall salmon runs in Europe.
The successful implementation of the European Water Framework Directive is a
very important concern for us.
Fish knowledge
The guild has been successfully monitoring fish population through electrofishing in the Frankfurt Main for over 20 years. This has given us excellent insights into present fish species and their reproduction. We are well aware of the deficits and problems of the water body. Additionally, we support bachelor’s and master’s theses on limnological and fish ecological topics. For example, the European catfish in the Main has been thoroughly studied regarding growth, parasites, and stomach contents with great success.
We are well aware of all fish ecological assessments.
From the local to the European level, we share our knowledge and findings.

FAQ
Where can I purchase fishing permits in order to fish the River Main in Frankfurt?
There are two options, you can either visit one of the four local retail shops such as Angel Bär or Askari in Offenbach or through a simple registration process online here.
Can I carry my permit digitally only on my smart phone?
Of course, simply by using the hejfish app or having your PDF permit saved on your smart phone.
Does the European catfish have a size limit or closed season?
None of the above applies to invasive catfish, hence all catfish must strictly be taken out of the river and kept.
Spinfishing is only legal beginning of June 01st of each year, am I allowed to fish dead baitfish on a rigged system and slowly drag that along the bottom before June 01st?
No, this is not legal.
I love to fish the drop-shot method with worm as bait. Is it legal to fish this way during the first five months of the year?
No, this method is prohibited for the first five months of each year.
My girlfriend got me this fancy drone for my birthday, can I use such a device to bring out my baits?
No, that is not legal. You’re allowed to fish two rods. Any other technical devices and aids such as drones, float tubes, paddle boats, remote controlled boats are not permitted.
I don’t know where I'm allowed to fish and not?
Each fishing permit comes with a very detailed map. The fishery orientates itself along the river mileage. The marker stones located along the river bank indicate every 200 meter. The map follows these marker stones for an easy way to differentiate the legal and closed areas.
I have no clue what these river marker stones look like?
The marker stones are small concrete cubes approximately 20 inches in size. Each stone has a number on it indicating the exact position.
I read in a bulletin board online that fishing from a boat is allowed, is that true?
This is not allowed. The rules and regulations are all in your fishing permit. What is written online in a board has no relevance.
As a catfish angler it is mandatory for me to present my baits and rigs with a small raft.
Nope, it’s illegal to use any sort of raft for fishing, be it to bring out your rigged baits or anything else.
I’ve witnessed anglers catching countless perch within a short time, were they allowed to do so?
Clearly no, you are according to the regulations allowed to keep three predatory fish per day such as pike, zander, perch or eel.
What should I do if a caught fish doesn't meet its size limit or it is closed season?
It’s then mandatory to release such a fish. Please do so in a fast manner by removing the hook fast and releasing the fish. If the fish swallowed the hook, rather cut the leader instead of trying to pull or remove the hook. In a best case scenario a fish should not be held out of the water for more than ten seconds!
To me it’s very important to take a proper grab’n’grin photo of the fish I catch, because I have many instagram followers. I practice catch & release only, anyhow!
Fish must be carefully released, especially if they are within the protected spawning period or smaller/larger than the legal size. The law does not allow anything else. Anyone who takes photos of their fish posing with them prior to releasing them later, risks that these fish will most likely die.
I remember well 35 years ago I’d catch countless cyprinids such as roach and bream while coarse fishing, not anymore; how come?
The river undergoes an ongoing change. The water quality was 40 years ago rather poor with lots of dissolved nutrients; especially bream did benefit from this. The water quality has changed dramatically to the better hence the bream are not that dominant anymore. Today the river has a much broader spectrum consisting of 34 fish species with an impressive population of predatory fish.
I find the gobies annoying!
Indeed the three goby species found in the river are invasive. They came approximately 20 years ago in the Main River in Frankfurt. The fish is now part of the stock, an ecological balance is established. Predatory fish have benefitted from this small fish. Gobies are not the most dominant species anymore. These are native fish such as roach or bleak.
Will my fishing permit be withdrawn if I don’t follow the rules and regulations?
Yes, very much indeed. When rules and regulations are disregarded, such as the illegal use of live bait or poor handling of fish and fishing in prohibited areas the permit is immediately revoked. This happens every year. Also anglers with multiple fishing crimes have been banned for up to five years.
Do people who get prosecuted for fish poaching pay a fine?
Yes, a large percentage of filed charges turn into a fine, usually between 600 and 1200 €. Often expensive fishing gear is also confiscated.
How many fish species do exist in the River Main?
To this day we count 34 different species. During the mid 1970s, there were only five species.
As long as I have a valid fishing permit, I can pretty much do what I want, right?
This is not correct, it’s very important to follow the law and regulations. If for example you fish in a prohibited area, this then turns into the crime of fish poaching.
How come you know which fish species live in the river?
For more than 20 years we have been assessing the fish stock through electrofishing. Various studies have been made on fish, also. We also use the statistics provided by anglers to determine the occurring fish species. It looks like a typo when you say that the guild was founded in the year 945? Do you rather mean it stems from 1945? No, the guild was indeed founded in the year 945. The guild is one of the oldest in the world.
