Sea Urchins in Genoa: the Riccola among rocks and trattorias

At six in the morning, on the rocks of Boccadasse, the water still has that cold transparency that the July sun has not yet warmed. Those who know the trade immerse themselves without hurry, with a mask worn by salt and a thick glove on just one hand. They search among the rocks, in the crevices where light barely filters through, for something dark, spiny, almost invisible to those who don’t know how to look. It is the sea urchin, and in Ligurian it has its own name: rissa, and in Genoa it is above all the protagonist of what Genoese call affectionately “la riccola”, the season of harvesting and consuming sea urchins.

This is not a postcard sea. It is a sea of rock, of cold currents rising from the seabed, of the smell of salt spray mixed with that of algae that the wave motion deposits on the rocks. The Ligurian Sea, in these stretches, does not have the golden sand of Sardinia or Caribbean transparency: it has a harsher, truer beauty, made of rocky seabeds where life clings and thrives in forms that must be sought out, not simply admired from a beach towel.

And it is precisely in these seabeds that the sea urchin, Paracentrotus lividus for those who love scientific names, finds its natural habitat: rocky walls, posidonia meadows, areas where the water moves but does not sweep away. A small creature that is both precious food and ecological sentinel, and that in Genoa tells a story as long as that of the fishermen who seek it.

The sea urchin: biology and ecological importance

The sea urchin belongs to the family of echinoderms, the same as starfish and sea cucumbers: close relatives, united by a radial symmetry found in the sea urchin’s very structure, with its five ovarian chambers arranged like a star inside the calcareous shell, the test. It is precisely those chambers, filled with orange gonads, that are the edible part: what Genoese simply call “the urchin”, to spread on a slice of bread or mix with a strand of spaghetti.

But the sea urchin is more than just food. It is a grazing herbivore that feeds on algae, and its presence — in balance — regulates the growth of algal meadows on coastal rocks. When sea urchins disappear due to overfishing or ecosystem imbalances, algae can proliferate uncontrolled; when instead sea urchins multiply unchecked, due to the absence of predators like certain species of sea breams, the opposite phenomenon leads to the formation of so-called “barrens”, stretches of bare rock where biodiversity collapses. The Ligurian Sea, with its meadows of protected Posidonia oceanica in several areas, hosts sea urchin populations that must be monitored precisely for this delicate balance.

Those who snorkel with mask and snorkel along the coasts between Boccadasse and Nervi, or further east towards Tigullio, can observe them without collecting them: wedged in crevices, often camouflaged with fragments of algae and shells that attach to their spines for protection from light and predators. It is a minor but fascinating spectacle, a detail of underwater life that those who swim carelessly on the surface never notice.

The gastronomic tradition: spaghetti, bruschetta and the taste of raw sea

In Genoa sea urchin is eaten mainly in two ways, both essential, both capable of restoring the taste of the sea without mediation. The first is bruschetta: toasted bread, just rubbed with garlic if you like, and on top the orange flesh of the sea urchin, raw, spooned directly from the just-opened shell. Nothing else is needed: neither lemon, which would mask the iodized flavor, nor seasonings that would distract from the natural saltiness.

The second is spaghetti with sea urchins, a dish that in recent decades has conquered the menus of restaurants and trattorias all along the Ligurian coast. The pasta should be drained al dente and tossed with sea urchin flesh, a drizzle of extra virgin olive oil, sometimes a touch of garlic barely brushed in the pan. The result is a dish that smells of rocky shores, of seaweed, of the open sea: the kitchen transposition of what divers collect just a few meters below the surface.

The traditional sea urchin season in Liguria follows the animal’s reproductive cycle: sea urchins are fuller and more flavorful in the cold months and spring, when the gonads develop in anticipation of reproduction, while in the height of summer the flesh tends to be scarcer. It is no coincidence that many seaside trattorias offer sea urchins especially from October to May, although availability always depends on catches and the local season.

“No gh’é bella rêuza ch’a no divente un grattacû.”

— Traditional Genoese proverb (there is no beautiful rose that does not become a headache)

Where to taste them: trattorias and restaurants by the sea

Along the Genoese coast and in the Ligurian east there are no shortage of historic establishments where sea urchin is treated with the respect it deserves: raw, fresh, just harvested. In Boccadasse, a fishermen’s village that still preserves colorful boats pulled dry on the pebbled beach, some historic trattorias offer sea urchin-based dishes in the right season, when local fishermen can source them. Also along the Anita Garibaldi promenade in Nervi, overlooking a particularly fish-rich stretch of rocky coast, you will find restaurants that value the catch of the day, sea urchins included when the season allows.

Heading east, in Tigullio, the sea urchin season tradition is even more deeply rooted: towns like Camogli and Santa Margherita Ligure have a centuries-old relationship with this small rocky fruit, and it is not uncommon to find, in the right months, festivals and celebrations dedicated precisely to sea urchins, occasions when entire towns gather around tables of bruschetta and spaghetti.

Fishing and gathering rules: a balance to respect

The harvesting of sea urchins in Italy is carefully regulated, precisely because of the ecological role these animals play in coastal ecosystems. There are daily quantity limits for amateur collection, a seasonal biological closure that varies from region to region, and in many areas harvesting is completely prohibited within marine protected areas.

Anyone venturing into sea urchin fishing as an amateur must inform themselves at local port authorities about the limits in force: the minimum shell diameter, the maximum number of specimens that can be collected per person per day, the forbidden periods. It’s not bureaucracy for its own sake: it’s the guarantee that this small piece of the Ligurian Sea ecosystem will continue to exist for future generations of divers, fishermen and food lovers.

Professional fishing, which supplies restaurants and markets, follows even stricter rules, with specific licenses and periodic checks on populations. It’s a niche sector but a living one, that holds together Genoese gastronomic tradition and the need to protect seabeds increasingly under pressure from coastal pollution and climate change that alters water temperatures.

Experiencing sea urchins underwater: conscious snorkeling

You don’t need to be an experienced diver to observe sea urchins in their environment. All it takes is a mask, a snorkel, and the patience to swim slowly along the rocky coasts that characterize much of the Genoese coastline, from Boccadasse to Nervi. On clear days, with the sun high, light filters down a few meters deep, illuminating the crevices where sea urchins hide among the seaweed.

Those who practice snorkeling with a naturalistic approach, without collecting anything, discover a small world that goes beyond the sea urchin itself: starfish, small sparid fish wandering among the rocks, sometimes even the first schools of damselfish with electric blue coloring that populate the warmer waters of late summer. It’s a way of experiencing the sea that doesn’t require expensive equipment, only respect and curiosity.

For those staying in the Historic Center or in the Porto Antico area, a snorkeling excursion towards the east is easily organized for a day trip, perhaps combining a morning in the water with lunch based on fresh local catch at one of the coastal trattorias.

The sea of Genoese: sea urchin gathering as daily ritual

For those born and raised along this coast, sea urchin gathering is not a tourist attraction: it’s a seasonal ritual passed down through families, often taught by a grandfather or uncle who knows the right rocks, the times when the tide uncovers certain crevices, the correct way to open the shell without wasting the meat. Many Genoese still experience the sea this way today: not as a backdrop for a photograph, but as a pantry, as a gym, as a place where you learn from childhood to swim among the rocks without fear.

Early morning, before the sun warms the water too much and before the beaches fill up, is the preferred time for the most experienced collectors: fewer people in the water, calmer sea, sea urchins still undisturbed in their hiding places. It’s an almost meditative moment, made of brief repeated breath-holds, of eyes that learn to distinguish a dark shape among the seaweed from a simple shadow on the rock.

This direct, almost physical relationship with the seabed is perhaps the most authentic hallmark of the way Genoa lives its own sea: not a decorative element, but a resource to know, respect, and — in the right measure — also to taste.

Practical tips for experiencing sea urchins in Liguria

For those wanting to approach this world, some concrete advice. If you want to taste sea urchins, ask restaurants about seasonality: the best months generally run from autumn to spring, while in midsummer availability may be more limited. Booking in advance at trattorias in Boccadasse and the Tigullio area is advisable, especially on weekends, when demand for fresh sea urchin dishes increases.

If instead you want to gather them yourself, always inform yourself at the local Port Authority about the seasonal and quantitative limits in force, and avoid marine protected areas where harvesting is prohibited. Bring with you resistant diving gloves, since the spines can break under the skin and cause annoying inflammation, and a special net for transport.

For naturalistic snorkeling, essential equipment remains mask, snorkel and light fins; neoprene footwear helps you move safely on the slippery rocks at the water’s edge. The best times are the morning hours, with calm sea and still-low light that makes observation among the rocks easier.

The sea as a reason to return

The sea urchin is a small detail of a much larger ecosystem, but it tells the character of this stretch of coast well: a sea that must be known to be truly loved, that doesn’t reveal itself immediately but rewards those who have the patience to look beneath the surface. Whether you choose to taste it at a trattoria overlooking the water or observe it in its natural habitat with mask and fins, sea urchins are an invitation to experience Genoa and Liguria at a different pace, slower, more authentic.

If this story has made you want to smell the salt air in the morning and discover firsthand the flavors of the Ligurian sea, our accommodations in the heart of Genoa are the ideal starting point. You can book your stay and discover, among rocks and trattorias, a sea that is lived, not just observed.
