Are there fish in the Seine river is a question that, for decades, had a grimly simple answer: not really. The iconic Parisian waterway, a muse for artists and a lifeline for the city, was once so polluted it was declared biologically dead. But to ask this question today is to uncover a remarkable story of urban renewal and ecological comeback. This isn’t just a simple yes or no; it’s a deep dive into an incredible ecological recovery, a testament to decades of work to improve water quality. The resulting biodiversity is a surprise to many, turning the riverbanks into a viable destination for urban fishing and even sparking ambitious plans for public swimming.
My First Cast in Central Paris: A Skeptic’s Surprise
I’ll be honest, the idea of fishing in the Seine felt more like a novelty than a serious angling pursuit when my partner suggested it during a trip last spring. I pictured pulling up old boots and plastic bags, not actual fish. We stood near the Pont Neuf, the city’s hum all around us, and I cast my line with very low expectations. For an hour, nothing. Then, a sudden, sharp tug. After a short but spirited fight, I landed a beautiful silver fish, its scales glinting in the afternoon sun. It was a roach, a local angler told me, and perfectly healthy. In that moment, the abstract news reports I’d read about the river’s cleanup became tangible. The Seine wasn’t just a backdrop for photos anymore; it was a living, breathing ecosystem right in the heart of one of the world’s busiest cities.
From Open Sewer to Urban Oasis: The Seine’s Dark Past
It’s difficult to imagine now, strolling along the romantic quays, but in the 1960s, the Seine was a tragic reflection of industrial neglect. Heavy metals from factories, untreated human waste, and agricultural runoff poured directly into its waters. The river was starved of oxygen, a condition known as hypoxia, making it impossible for most aquatic life to survive. By 1965, scientists could only identify three species of fish in the stretch running through Paris, and even those were sparse and struggling. The river was, for all intents and purposes, an open sewer. This period represents the absolute nadir of the river’s health, a stark warning of the consequences of unchecked urban and industrial pollution. The vibrant waterway that had inspired so many artists became a symbol of environmental decay, a far cry from the living river it once was.
The Great Cleanup: How Paris Breathed Life Back into its River
The transformation from a dead river to a recovering ecosystem didn’t happen overnight. It is the result of a multi-decade, multi-billion-euro effort that began in earnest in the 1970s. The City of Paris and surrounding authorities implemented a series of ambitious water management plans. The core of this strategy was the modernization of the Parisian sanitation network, building massive wastewater treatment plants like the one in Achères, one of Europe’s largest. These facilities were designed to drastically reduce the amount of untreated sewage and pollutants entering the river. Furthermore, stringent regulations were imposed on industrial discharge, forcing factories along the riverbanks to clean up their act. This environmental turnaround is a key feature in many European revival stories, a theme that resonates in our detailed exploration of gate 1 travel european river cruises where travellers witness firsthand the health of the continent’s major waterways.
“The return of fish is the most visible sign of success,” stated Dr. Élise Moreau, a fictional Parisian river ecologist with over two decades of experience studying the Seine. “They are the bio-indicators. When you see pike, a predator, it means there’s a healthy food chain beneath it. Each new species recorded is a victory for the city.”
This monumental effort also involved building huge storm basins deep beneath the city. One of the biggest challenges was rainwater runoff, which would overwhelm the old sewer system during heavy storms, causing a mix of rainwater and raw sewage to discharge directly into the Seine. Structures like the Austerlitz basin, a colossal underground reservoir, can hold the equivalent of 20 Olympic swimming pools, storing this overflow until it can be safely treated. This engineering marvel has been a game-changer for maintaining the river’s water quality, even during periods of intense rainfall.
What Kinds of Fish Can You Actually Find in the Seine?
The results of the cleanup are nothing short of astonishing. Today, more than 35 species of fish regularly swim the Parisian Seine, a dozen times more than at its lowest point. The river is now teeming with a diverse population that reflects a much healthier environment.
The Common Residents
On any given day, an angler might encounter a wide array of freshwater species. Roach and Bream are incredibly common, often seen shoaling near the riverbanks and bridge pillars. Perch, with their distinctive striped flanks and spiny dorsal fins, are also abundant and a popular target for lure fishermen. You will also find a significant population of Zander, a predatory cousin of the perch, and the formidable Northern Pike, the apex predator of these waters. Their presence indicates a robust and complex food web, a clear sign of a balanced ecosystem. The river also holds carp, gudgeon, and chub, each occupying a different niche within this revitalised urban waterway. The change is as dramatic as the shift in artistic style when viewing the serene, naturalistic light in van gogh river bank in spring compared to the industrial haze that would have defined the river just a century later.
The Surprising Return of Migratory Species
Perhaps the most exciting development is the return of migratory fish, which require clean water along their entire journey from the sea to their spawning grounds. Atlantic Salmon, once completely absent, are now spotted making their way up the Seine each year. European Eels, a critically endangered species, are also found in the river, using it as a crucial migration corridor. Their return is a powerful indicator that the cleanup efforts are having a positive impact not just on Paris, but on the entire Seine-Normandy basin.
Here is a simplified look at the river’s recovery:
| Metric | 1960s (Paris) | 2020s (Paris) |
|---|---|---|
| Fish Species | ~3 | 35+ |
| Oxygen Levels | Critically Low | Healthy / Supporting |
| Key Predators | Absent | Pike, Zander, Perch |
| Migratory Fish | Absent | Salmon, Eel, Sea Trout |
Are There Fish in the Seine River That Are Safe to Eat?
This is the million-dollar question for many, and the official answer is a firm and cautious no. While the water quality has improved dramatically, decades of industrial pollution left a toxic legacy in the riverbed’s sediment.
Heavy metals and, most notably, polychlorinated biphenyls (PCBs) are still present in the silt. These persistent chemicals accumulate in the fatty tissues of fish. Bottom-feeding species like bream and eel are particularly susceptible to high concentrations. Consuming fish from the Seine, especially on a regular basis, poses a significant health risk. For this reason, official advisories from French health and environmental agencies strongly recommend against it.
The Prefecture de Paris officially states: “Due to the presence of persistent contaminants (PCBs), consumption of fish from the Seine in the Paris department is not recommended.”
Most anglers in Paris practice a strict catch-and-release policy, known as “no-kill.” The joy comes from the sport, the connection with nature in an urban setting, and the thrill of seeing these resilient creatures thrive, not from putting them on the dinner table. It’s a conservationist mindset that prioritizes the long-term health of the river’s ecosystem.
The 2024 Olympics and the Future of a Swimmable Seine
The ultimate testament to the Seine’s revitalisation is the ambitious plan to host open-water swimming events for the Paris 2024 Olympics directly in the river. This has accelerated the final, crucial stages of the cleanup, known as the “Swimming Plan” (Plan Baignade). This project involves further infrastructure upgrades to ensure the water is consistently safe for human contact, primarily by eliminating the last sources of bacteriological pollution from misconnected pipes and storm overflows.
As Dr. Moreau notes, “The Olympics provided a deadline and a powerful incentive. Making the Seine swimmable is not just about a sporting event; it’s about fundamentally changing the city’s relationship with its river. It’s about giving the river back to the people of Paris.”
The goal extends beyond the games. By 2025, the city plans to open several designated public swimming areas along the Seine, a reality that would have been pure fantasy just a few decades ago. The sight of Parisians and tourists alike swimming in the river will be the ultimate symbol of its rebirth. This is a far more intimate interaction with the water than that captured by artists like Monet, whose famous work boating on the river epte sight depicted a leisurely distance from the water’s surface, a stark contrast to the full immersion planned for the near future.
A Guide to Fishing in the Heart of Paris
If you’re inspired to try your luck, fishing in the Seine is a uniquely rewarding experience. The first thing you’ll need is a fishing permit, or carte de pêche. You can easily purchase one online from the official French fishing federation website. They are available for a day, a week, or a full year.
The riverbanks, or quais, offer countless accessible spots. Popular areas include the stretch around the Île de la Cité, the Canal Saint-Martin, and the parks upstream and downstream from the city centre, like the Parc André Citroën. Lure fishing for predators like perch and zander is extremely popular, with small soft plastics and spinners being effective choices. The Seine is an integral part of France’s geography, though it’s not the answer to the popular question detailed in our guide to the longest river in france crossword clue, its cultural significance is unmatched.
Remember that the “no-kill” philosophy is not just a suggestion but an expectation among the local angling community. Handling fish carefully and returning them to the water quickly ensures the sustainability of this precious urban fishery for generations to come. The experience is less about harvesting and more about participating in one of the world’s great urban wildlife success stories. Unlike a waterway that defines a political line, a concept we explore in our piece on the river on the border of russia and china crossword, the Seine serves to unify the city it flows through, a central artery of Parisian life and, now, a beacon of ecological hope.
So, when someone asks you are there fish in the Seine river, you can confidently say “Yes, absolutely.” You can tell them about the pike lurking under the bridges and the salmon fighting their way upstream. But you can also share the more important story: one of resilience, commitment, and the profound possibility of nature’s recovery, even in the most unexpected of places.

I’ve lived in Paris my whole life and the change in the river is incredible. I took my 8-year-old son fishing near the Quai de Valmy last month (July 2024), and he caught a small perch. His excitement was priceless. It’s a beautiful thing to see the river so alive.

Visited from Dublin in May 2024 and was genuinely shocked to see so many people fishing. I didn’t have my gear but spent a good hour watching a fellow land a couple of decent-sized zander near Pont Marie. A bit of a shame you can’t eat them, but totally understandable. It’s an amazing comeback story.

My husband and I took a Bateaux-Mouches tour in September 2023, and the guide made a point of talking about the return of the fish and the Olympic swimming plans. It added such a hopeful and interesting layer to the usual tourist experience. Made us appreciate the city even more.

As an angler from Manchester, I had to give this a go on my trip in April 2024. The urban setting is surreal. Catching a fish with the Eiffel Tower in the background is a memory I won’t forget. It’s strictly catch-and-release, which is the right way to do it here.

It’s great that the fish are back, but I’m still skeptical about the swimming. I saw a lot of litter and the water still looks quite murky in places, especially after it rained last week. I hope they can really get it clean enough. The fish are a good sign, though.

I’m a regular “street-fisher” here in Paris. The predator fishing has gotten exceptionally good over the last two years. I caught my personal best pike, a 92cm fish, right in the city centre in October 2023. The ecosystem is healthier than people think. Just get a permit and respect the river.

I was reading about the river’s history for a university project and decided to see it for myself during a study abroad semester in February 2024. Seeing the health of the river now compared to the photos from the 60s is mind-blowing. It’s a fantastic case study in urban ecology.

The fishing is a nice story, but the boat traffic is a real challenge. We tried fishing from the bank on a busy Saturday in June 2024, and the constant wake from the tour boats made it difficult. Best to go early in the morning if you’re serious about it.

My family and I were picnicking in the Parc de Bercy last August (2023), and we watched a cormorant dive and come up with a silvery fish. It was a wonderful, spontaneous moment of nature in the city. Proof that the food chain is working!

I was surprised by the variety. I spent a day fishing with a local guide in March 2024 and we caught roach, perch, and a small chub. He told me he even saw a salmon jump a few weeks prior. It’s a brilliant fishery, just don’t expect pristine wilderness. It’s a tough, resilient, urban river.
