The waters off Israel's coast hold a surprisingly complex and contested ecosystem. The Levantine Basin is warm, salty, and nutrient-poor — made worse when the Aswan Dam cut off the Nile's nutrient-rich sediment flow in the 1960s, collapsing sardine stocks. Native species include gilthead sea bream (denis), the prized but slow-maturing dusky grouper (daqar), flathead grey mullet (buri) used in the national dish dag sameach, and the hallucinogenic salema (Sarpa salpa) whose heads can induce LSD-like effects. But the real story is the Lessepsian migration: since the Suez Canal opened in 1869, over 100 Red Sea fish species have invaded the Mediterranean. Rabbitfish (sikan) now dominate, overgrazing algae and turning complex reef habitats into barren "underwater parking lots." The counterintuitive solution? Eat them. Israeli fisheries and restaurants now promote rabbitfish as a sustainable choice, turning an ecological crisis into dinner.

#3580: The Fish That Changed Israel's Coastline

Corn
Daniel sent us this one — he's asking about fish in Israel. The country's got the Mediterranean on one side and the Sea of Galilee up north, but fish has never really been a big part of the local diet the way it is in, say, Greece or Turkey. He wants to know what's actually swimming in these waters, which species are worth eating, whether overfishing is a problem, and if you're someone who cares about eating fish ethically, where you'd go for a genuinely good fish restaurant. It's basically a guided tour through Israel's underwater real estate, with dinner at the end.
Herman
I love this. I love this. Because most people, even Israelis, couldn't name five local fish species if you put a plate in front of them. And yet the eastern Mediterranean is one of the most historically fished bodies of water on earth. You've got Phoenician fish-salting operations from three thousand years ago along this coast. There's a whole submerged world people just don't think about.
Corn
The phrase "historically fished" is doing a lot of work there. Three thousand years of humans pulling things out of the same stretch of water — you'd think we'd have either perfected it or emptied it by now.
Herman
That's exactly the tension. The Mediterranean off Israel's coast — we're talking about the Levantine Basin, which is the southeastern corner of the Med — it's actually not the most naturally productive marine ecosystem. It's warm, it's salty, it's relatively low in nutrients compared to, say, the Aegean or the Adriatic. The Nile used to pump enormous amounts of nutrient-rich sediment into this part of the Mediterranean, but the Aswan Dam basically shut that off in the nineteen sixties. So the whole ecosystem shifted.
Corn
Wait, the Aswan Dam in Egypt changed Israel's fish stocks?
Herman
The Nile flood pulse used to create this massive plume of freshwater and nutrients that spread along the Levantine coast. Sardine stocks collapsed after the dam was built — Egypt's own sardine fishery dropped from about eighteen thousand tons a year to almost nothing within a few years. Israel felt it too. The whole food web contracted.
Corn
The fish were basically living off Egypt's agricultural runoff for millennia and we didn't realize it until someone turned off the tap.
Herman
That's a very Corn way of putting it, but yes. And it's one reason the eastern Mediterranean is considered oligotrophic — nutrient-poor — compared to other marine systems. But that doesn't mean there's nothing there. You've got a mix of native species and, increasingly, invasive species coming through the Suez Canal.
Corn
Right, the Lessepsian migration. That's the thing where Red Sea species come up through the canal into the Mediterranean.
Herman
Named after Ferdinand de Lesseps, who built the Suez Canal. And it's one of the most dramatic marine invasions on the planet. Over a hundred fish species have crossed from the Red Sea into the Mediterranean since the canal opened. Some of them have completely reshaped the local fishery. We'll get to those.
Corn
Let's start with what's native. If I'm standing on the beach in Tel Aviv and I look out at the water, what's actually swimming out there?
Herman
The native fish community in the Levantine Basin — and I pulled some of this from Israeli fisheries surveys and a few marine biology papers — you've got several families that matter both ecologically and commercially. First, the sparids. That's the sea bream family. The most important native sparids include the gilthead sea bream, which in Hebrew is denis — that's probably the most famous premium fish in Israel.
Corn
Denis is the one that shows up on every respectable menu.
Herman
Silver, with that distinctive gold band between the eyes — hence "gilthead." It's a coastal fish, lives in seagrass beds and sandy bottoms, and it's a protandrous hermaphrodite, which is a fun fact I'm going to force you to hear.
Corn
I'm braced.
Herman
They all start as males and then transition to female as they get larger. So the big denis you want on your plate — that's a female. Commercially, most denis you eat in Israel today is farmed, not wild. And we'll get to aquaculture because that's its own whole story. But wild denis is still caught, just in much smaller numbers.
Corn
What else is in the sparid family?
Herman
You've got the common pandora — that's farida in Hebrew — which is a smaller bream, pinkish, very delicate flesh. There's the white seabream, which is called sargus. There's the striped seabream. And then there's a fish called shefarnun in Hebrew, which is the salema or dreamfish — Sarpa salpa — and that one has a bizarre property.
Herman
If you eat the head of a Sarpa salpa, particularly during certain seasons, you can experience hallucinations. It's been documented since Roman times. The fish accumulates indole alkaloids from the algae it eats, and those compounds can produce LSD-like effects.
Corn
Somewhere off the coast of Herzliya there's a psychedelic sea bream just swimming around, waiting to ruin someone's Tuesday.
Herman
Or make it. The Romans reportedly used it recreationally. There are accounts of Arab physicians in the medieval period writing about it. It's not a common food fish in Israel today, for obvious reasons, but it's absolutely part of the local ichthyofauna.
Corn
The walking encyclopedia strikes again. Alright, beyond the breams.
Herman
The grouper family — that's the serranids. The dusky grouper, Epinephelus marginatus, is the big one. In Hebrew it's daqar. It's a large, long-lived reef-associated predator. Can grow to a meter and a half, weigh over sixty kilos. It's one of the most prized fish in the Mediterranean. And it's also one of the most threatened.
Corn
Because it takes so long to mature?
Herman
Groupers are slow-growing, late-maturing, and they aggregate to spawn in specific locations at predictable times, which makes them incredibly vulnerable to overfishing. A dusky grouper might not reach sexual maturity until it's seven or eight years old. If you catch it before then, it never reproduces. And because they command high prices, there's intense pressure on wild stocks.
Corn
The daqar on a menu is a bit of a red flag.
Herman
We'll get to the sustainability question. But yes, wild dusky grouper is a concern throughout the Mediterranean. There's also the white grouper, Epinephelus aeneus, which is slightly less threatened but similar story. And the goldblotch grouper, which is actually a Lessepsian migrant — came through the Suez — but has established itself and is now commercially fished.
Corn
Before we get deeper into the invasives, what else is native and worth knowing about?
Herman
You've got the mullets — that's the mugilids. The flathead grey mullet is called buri in Hebrew, and it's enormously important in Israeli fish culture. Mullet is the fish used for dag sameach — literally "happy fish" — which is the classic Israeli preparation: fried mullet fillets, often served with tehina. It's a coastal fish, tolerates a wide range of salinities, and it's also the primary fish farmed in Israeli aquaculture going back decades.
Corn
Dag sameach is basically the national fish dish, if Israel had one.
Herman
It's the closest thing. Mullet is not a fancy fish — it's not denis or daqar — but it's beloved, it's affordable, and it's deeply embedded in the food culture. You also have the red mullet, which is a completely different fish. That's Mullus barbatus or Mullus surmuletus — called mulit in Hebrew, sometimes translated as "sultan Ibrahim" in English. Small, pinkish, very delicate. It was prized in ancient Rome — Apicius has recipes for it — and it's still considered a delicacy.
Corn
The ancient Romans, again. They really got around the Mediterranean seafood scene.
Herman
They were obsessive about fish. There's a reason garum — fermented fish sauce — was one of the most traded commodities in the Roman Empire. But I'll spare you the garum tangent.
Herman
Moving on: you've got the bluefish, which is called tarsan in Hebrew. It's a migratory predator, aggressive, travels in schools, and it's popular among recreational anglers because it fights hard. The flesh is oily and strong-flavored — some people love it, some find it fishy in a bad way. It's divisive.
Corn
The cilantro of fish.
Herman
That's actually perfect. Then there's the little tunny — Atlantic bonito, or palamida in Hebrew — which is a small tuna species, very common in Israeli waters seasonally. And the European anchovy, which is the basis of a small but important local fishery, mostly for the domestic market. Anchovies are one of the few pelagic schooling fish that are still relatively abundant here.
Corn
So we've got breams, groupers, mullets, bluefish, bonito, anchovies. That's the native cast. Now the Suez Canal opens and everything changes.
Herman
The Lessepsian migration. And this is where the story gets really interesting. Since the Suez Canal opened in eighteen sixty-nine, you've had a steady stream of Red Sea and Indo-Pacific species moving north into the Mediterranean. The canal was widened and deepened several times, most recently in twenty fifteen, which removed a lot of the natural barriers — the Bitter Lakes used to be a hypersaline barrier that slowed migration, but they've been diluted over time. And the Mediterranean is warming, which makes it more hospitable to tropical species.
Corn
It's essentially a one-way highway from the Red Sea into the Med.
Herman
There's some movement the other way, but the dominant flow is northward. And some of these invaders have become commercially dominant. The most important one, by far, is the rabbitfish.
Corn
That sounds made up.
Herman
Siganus rivulatus and Siganus luridus. In Hebrew they're called sikan. They're small, spiny, herbivorous fish — they graze on algae — and they've absolutely exploded in the eastern Mediterranean. In some Israeli coastal surveys, rabbitfish now account for something like forty to eighty percent of the fish biomass on rocky reefs. They've displaced native herbivores like the salema. They're everywhere.
Corn
Are they good to eat?
Herman
They're actually quite good. The flesh is white, firm, mild. They have venomous dorsal spines that can give you a nasty sting if you handle them carelessly, but once they're cleaned they're perfectly safe. Israeli fishermen initially didn't target them because they weren't familiar, but now they're a major part of the catch. You'll see sikan in markets, you'll see it fried whole in restaurants. It's become a staple.
Corn
What's the ecological impact? If they're forty to eighty percent of the biomass, they must be eating something.
Herman
They're eating the algae, which sounds harmless, but it creates something called a trophic cascade. Rabbitfish overgraze the algal forests that provide habitat for native species. The underwater seascape in parts of the Israeli coast has shifted from complex, forest-like algal communities to barrens — basically underwater parking lots. And that reduces biodiversity across the board. It's one of the most dramatic examples of marine invasion in the world.
Corn
Underwater parking lots. That's a grim image.
Herman
It's the Mediterranean equivalent of what's happening with lionfish in the Caribbean. And just like lionfish, the best management strategy people have come up with so far is: eat them.
Corn
The human solution to ecological disaster: make it dinner.
Herman
It's not a joke, actually. There are restaurants and fisheries in Israel, in Cyprus, in Turkey that are actively promoting rabbitfish as a sustainable choice. The idea is to create market demand that incentivizes fishermen to target the invader rather than the depleted native species. Kill two birds with one stone — or catch two fish with one net.
Corn
What other Suez Canal celebrities should we know about?
Herman
The goldblotch grouper I mentioned. The red soldierfish — a small, reddish reef fish that's now very common. The spotfin squirrelfish. The brushtooth lizardfish, which has the distinction of being one of the ugliest fish in the sea and also delicious, apparently. And the Indo-Pacific swimming crab, which isn't a fish but has become a major commercial shellfish species here.
Corn
The invasive species are, in some ways, propping up the local fishery.
Herman
And that creates a weird ethical knot. If you're an environmentally conscious consumer, which fish do you choose? The native species that's being overfished and needs protection, or the invasive species that's destroying the ecosystem but is abundant and arguably should be eaten? It's not straightforward.
Corn
Let's talk about the freshwater side. The prompt mentions the Sea of Galilee. What's in the Kinneret?
Herman
The Kinneret — the Sea of Galilee — is Israel's only natural freshwater lake, and it has its own distinct fish community. The most famous is the St. Peter's fish.
Corn
The one Jesus allegedly caught.
Herman
The story is in the Gospel of Matthew — Peter catches a fish with a coin in its mouth to pay the temple tax. The fish is traditionally identified as a tilapia species. In the Kinneret, you've got several tilapia species, but the main one is the Galilee tilapia, Oreochromis aureus, which in Hebrew is called amnun. It's a cichlid — related to the tilapia you see farmed globally — and it's been eaten around the Kinneret for thousands of years.
Corn
Amnun is the one you get fried whole at those lakeside restaurants near Tiberias.
Herman
And it's mostly farmed now. Wild amnun stocks in the Kinneret have declined significantly. The lake's water level has been dropping for years — it's Israel's main natural reservoir and it's been heavily drawn down — and that affects spawning habitat. The amnun builds nests in shallow water, and when the shoreline recedes, those nests are exposed.
Corn
What else is in the lake?
Herman
You've got the Kinneret sardine, which is actually a small bleak — Acanthobrama terraesanctae — and it's the most abundant fish in the lake. It's not a true sardine, but it fills a similar ecological niche. There's the Galilean loach. There's the catfish — the African sharptooth catfish, which can grow quite large. And there's the Kinneret bleak, Mirogrex terraesanctae, which was only recognized as a distinct species relatively recently and is endemic — it exists nowhere else on earth.
Corn
Endemic species are always the ones that make me nervous. One drought, one pollution event, and it's gone.
Herman
That's a real concern. The Kinneret ecosystem is under pressure from water extraction, climate change, agricultural runoff, and introduced species. The silver carp was introduced decades ago and has become dominant. The mosquitofish was introduced for pest control. These introductions have reshaped the food web.
Corn
The Kinneret is basically a case study in how small, isolated freshwater systems get stressed from every direction.
Herman
It's a microcosm of global freshwater biodiversity loss. And it's a lake that matters to a lot of people — religiously, historically, culturally — but the fish are often an afterthought in water management decisions.
Corn
Let's get to the big question. How bad is it in Israeli waters?
Herman
It's bad, but it's a specific kind of bad. The Mediterranean as a whole is the most overfished sea in the world according to the UN's Food and Agriculture Organization. Something like seventy-five percent of assessed fish stocks in the Mediterranean are overexploited. Israel is part of that picture.
Corn
Seventy-five percent. That's not "a concern." That's a slow-motion collapse.
Herman
Here's the thing about Israeli fisheries specifically. It's a small country with a narrow continental shelf. The productive fishing grounds are limited. The commercial fleet is relatively small — we're talking maybe a few hundred vessels, mostly small trawlers and artisanal boats — but the pressure is concentrated. And there's a long history of poor enforcement. The Fisheries Department has limited resources. Illegal, unreported, and unregulated fishing has been a persistent problem.
Corn
What are they catching that they shouldn't be?
Herman
Trawling is the biggest issue. Bottom trawling in particular — dragging weighted nets across the seafloor — destroys benthic habitats, catches juvenile fish before they can reproduce, and produces huge amounts of bycatch. There have been efforts to restrict trawling, including seasonal closures and minimum depth limits, but enforcement is spotty. A report from the Society for the Protection of Nature in Israel a few years back found that trawling was occurring inside protected areas.
Corn
Of course it was.
Herman
The dusky grouper is a particular worry. Landings have dropped dramatically over the past few decades. The same goes for some of the larger breams and the meagre — a large croaker that's prized for its flesh. Recreational fishing is also a factor — there are tens of thousands of recreational anglers in Israel, and while individually they don't catch much, collectively they can have an impact on near-shore species.
Corn
What about the invasive species — are they being overfished?
Herman
Not really, and that's the silver lining. The rabbitfish, the soldierfish, the lizardfish — they're abundant, they reproduce quickly, and they're not under the same pressure as the slow-growing natives. That's why the "eat the invaders" strategy has some ecological logic to it. If you're going to eat fish in Israel, eating the Lessepsian migrants is arguably the most sustainable choice you can make.
Corn
We've arrived at the ethical fish consumer question. Given everything we've just laid out — the depleted natives, the invasive species, the trawling problem, the aquaculture option — where do you actually go?
Herman
Let's break it down. First, the species. If you want to eat fish in Israel and feel reasonably good about it, I'd say: rabbitfish, sikan, is probably your best bet. It's invasive, it's abundant, it's not being depleted, and eating it reduces pressure on native herbivores. It's also good — mild, versatile, takes well to frying or grilling.
Corn
Sikan: the ethical choice that also happens to be everywhere.
Herman
Second, farmed fish. Israeli aquaculture is actually quite sophisticated. The country has been farming fish since the nineteen thirties — carp and mullet in ponds, initially — and now there's a significant marine aquaculture sector. Sea bream, or denis, is farmed in offshore cages in the Mediterranean. It's a well-managed operation, the feed conversion ratios are decent, and it takes pressure off wild stocks. Farmed denis is a solid choice.
Corn
What about farmed versus wild in terms of taste?
Herman
Wild denis is generally considered superior — firmer texture, more complex flavor, because it's eating a natural diet of crustaceans and mollusks. But the gap has narrowed. High-quality farmed denis, fed on good formulated diets, can be excellent. And from a sustainability standpoint, it's the clear winner unless you know the wild fish came from a well-managed fishery, which in Israel is hard to verify.
Corn
Farmed denis, wild sikan.
Herman
Mullet is a decent option, especially farmed mullet. It's a low-trophic-level fish — meaning it's low on the food chain, eats algae and detritus — so farming it has a lower environmental footprint than farming carnivorous fish like salmon. And it's the backbone of Israeli pond aquaculture. The mullet you get at a good fish restaurant is likely farmed and it's likely local.
Herman
Small pelagic fish like anchovies are generally a good sustainability bet — they're abundant, they reproduce quickly, they're low on the food chain. The Israeli anchovy fishery is small and mostly supplies the local market. It's not a high-profile fish, but if you see fresh anchovies on a menu, that's a defensible choice.
Corn
What should we avoid?
Herman
Wild dusky grouper, daqar, is the main one. It's a threatened species throughout the Mediterranean, and Israeli stocks are in decline. If you see daqar on a menu, you should ask whether it's wild or farmed. There is some grouper aquaculture happening, but it's not widespread. Wild white grouper is also a concern. Large, slow-growing predators in general — they're the ones that get hit hardest by overfishing.
Herman
Sharks in the eastern Mediterranean are in terrible shape. There's a small but real shark fishery, mostly for the local Arab market — shark is used in a traditional dish called shakshouka samak in some communities — but many of the species caught, like the sandbar shark and the smoothhound, are critically endangered in the Mediterranean. It's really not something you want to be eating.
Corn
So now the restaurant question. Where does someone go for excellent fish in Israel, with all of this in mind?
Herman
There are a few places that consistently come up. In Tel Aviv, there's a restaurant called Manta Ray — it's right on the beach, it's been around for years, and they're known for sourcing carefully and preparing fish simply. Good mezze, grilled fish, fresh ingredients. It's not cheap, but it's reliable.
Corn
Manta Ray is almost a cliché at this point, but it earned it.
Herman
Then there's Benny HaDayag — Benny the Fisherman — which has a few locations, including in Tel Aviv and Herzliya. It's more of a casual, traditional fish restaurant. They do the classic Israeli fish preparations: fried mullet, grilled denis, fish kebabs. It's not fancy, but it's honest.
Corn
The kind of place where the menu is laminated and the fish is fresh.
Herman
In Jaffa, there's a concentration of fish restaurants near the port. Some of them are tourist traps, but there are gems. I'd point to a place called Kalamata — it's small, Greek-influenced, does excellent grilled fish and seafood. The owner is Greek-Israeli and takes sourcing seriously.
Corn
What about up north, near the Kinneret?
Herman
Around Tiberias, the classic experience is the St. Peter's fish restaurants along the lakefront. Most of them serve farmed amnun, fried or grilled, with chips and salad. It's more about the experience than the culinary sophistication. But if you want something a bit more elevated, there's a restaurant called Decks in Tiberias that's built on a wooden deck over the water and does a respectable fish menu.
Corn
Anywhere in Haifa or the north coast?
Herman
In Akko — Acre — there's a restaurant called Uri Buri. This is the one that everyone who knows Israeli seafood talks about. Uri Jeremias is the chef-owner, he's been doing this for decades, and he's obsessive about fish quality. The menu changes based on what's fresh. He serves things like sikan, like small local shrimp, like whatever came in that morning. It's in a restored Ottoman building in the old city. It's probably the closest thing Israel has to a destination seafood restaurant.
Corn
Uri Buri has the reputation of being the place where even the chef's mistakes are better than most restaurants' best efforts.
Herman
That's not far off. And Uri himself is a character — big beard, big personality, very outspoken about sustainable fishing. He's been advocating for eating invasive species for years. He puts sikan on the menu and tells you why. So if you're an ethical fish consumer, Uri Buri is basically your pilgrimage site.
Corn
Any other notable spots?
Herman
There's a place in Tel Aviv called Goocha, which is a seafood and fish bar that's been around a long time and does things well. There's a chef restaurant called Popina in Neve Tzedek that does beautiful, modern fish dishes. And in the Carmel Market area, there are small, no-frills fish restaurants where you can get excellent fried fish for next to nothing — it's not white-tablecloth dining, but it's authentic and often really good.
Corn
The market stalls are where you find the real food in any country.
Herman
And in Israel, the fish market culture isn't as developed as the meat or produce market culture, but it's there. The Tel Aviv port area used to have a proper fish market. Today, the main wholesale fish market is in the Tel Aviv port industrial zone, and it's worth visiting early in the morning if you want to see what's actually being landed.
Corn
I want to circle back to something you mentioned earlier. How big a deal is fish farming in Israel right now?
Herman
It's big and getting bigger. Israel's total fish production is around twenty to twenty-five thousand tons a year, and roughly eighty percent of that is farmed. The majority is freshwater pond aquaculture — carp, tilapia, mullet — but marine cage aquaculture has been growing. There are fish farms off the coast of Ashdod and in the Gulf of Eilat. The main marine species farmed is gilthead sea bream, denis, and there's also some European sea bass.
Corn
The Red Sea aquaculture — that's in Eilat?
Herman
Yes, and it's actually an interesting operation. The Gulf of Eilat is a unique ecosystem — it's a semi-enclosed sea with coral reefs, and there's been a lot of debate about the environmental impact of fish farms there. The farms are in deep water, well offshore, and the currents disperse the waste. But there have been concerns about nutrient loading and impacts on the coral. The monitoring data suggests it's being managed reasonably well, but it's something that environmental groups watch closely.
Corn
Even the "solution" has complications.
Herman
Everything in marine conservation has complications. That's the through-line of this entire conversation. There's no perfectly clean choice. You're always trading off something — carbon footprint, biodiversity impact, animal welfare, local economies. The best you can do is be informed and make choices that align with what you care about most.
Corn
Which is basically the thesis statement of ethical consumption in any domain.
Herman
And I think with fish in Israel specifically, the "eat the invaders" frame is helpful. It gives you a clear, defensible default: rabbitfish, farmed denis, mullet, anchovies. If you're at a restaurant and you don't recognize a fish name, ask. If the server can't tell you whether it's wild or farmed, that's information in itself.
Corn
One thing we haven't touched on is the import market. A lot of fish eaten in Israel is imported — salmon from Norway, tuna from who knows where, frozen fillets from Asia. How does that fit into the ethical picture?
Herman
It's complicated. Imported salmon, for instance — most of it is farmed Atlantic salmon, and the environmental record of salmon farming varies enormously by producer. Norwegian salmon farming has improved its practices significantly in the past decade — lower antibiotic use, better feed sustainability, better escape prevention — but it's still an industrial operation with real impacts. And then there's the carbon footprint of flying frozen fish from Norway to Israel.
Corn
Local farmed fish probably has a lower carbon footprint than imported salmon, even if the production systems are comparable.
Herman
And there's an argument for supporting local fisheries and aquaculture just on food sovereignty grounds. Israel imports a lot of its food, and the more of your protein you can produce domestically, the more resilient your food system is.
Corn
The food security angle. That's going to resonate with a certain kind of listener.
Herman
And it connects to something I think about a lot with Israeli agriculture and aquaculture. This is a country that turned the desert into farmland and is now turning the sea into a protein source. The innovation story is real. But it has to be done carefully, with good science and good regulation, or you end up with the underwater parking lots.
Corn
To pull this together for someone who wants to eat fish in Israel ethically: prioritize invasive species like rabbitfish, choose farmed over wild for native species like denis, eat low on the food chain when possible, avoid wild grouper and sharks, and if you're dining out, places like Uri Buri and Manta Ray are doing it right.
Herman
That's the summary. And I'd add: ask questions. The more consumers ask about sourcing, the more restaurants and fishmongers have to pay attention. The market responds to demand. If people start asking "is this sikan?" or "is this farmed?" — that sends a signal.
Corn
The ethical consumer as market signal. It's not a revolution, but it's not nothing either.
Herman
It's what we've got. And honestly, the fish in Israel is good. The Mediterranean has this incredible concentration of flavor — the salinity, the warmth, the diet of crustaceans and small fish — it produces fish that taste like the sea in the best possible way. You can eat well and eat responsibly. You just have to know what you're looking at.
Corn
Now you do.
Herman
Now we all do.
Corn
One last thing. The prompt asked about overfishing being a concern. The answer is clearly yes, but you've framed it in a way that's more nuanced than just "the ocean is dying." What's the single thing you'd want listeners to take away about the state of Israeli fisheries?
Herman
That the Mediterranean is overfished — that's the baseline reality — but Israel's specific situation is shaped by the Lessepsian migration in a way that's almost unique globally. You have a native fish community that's depleted and an invasive fish community that's thriving, and the two are connected. The invaders are partly responsible for the decline of the natives — through competition and habitat alteration — but they're also providing a fishery that takes pressure off what's left. It's a weird, dynamic equilibrium, and it's not stable. Climate change is going to keep tilting the playing field toward the tropical invaders. The Mediterranean of twenty fifty is going to look very different from the Mediterranean of today.
Corn
A whole sea in transition. That's a big thought to end on.
Herman
It's a big thought. And it's happening whether we pay attention or not.
Corn
Now: Hilbert's daily fun fact.

Hilbert: The ancient Greeks used a device called a klepsydra — a water clock — to time speeches in court, but the Yukon's indigenous peoples independently developed a similar instrument using carved bone vessels that measured time by the drip of melting ice, often calibrated to the breathing rate of a resting caribou, effectively making the caribou an unwitting timekeeping partner.
Corn
A caribou as a horological collaborator. That's a sentence I didn't expect to hear today.
Herman
I'm just imagining a courtroom in the Yukon where the lawyer's argument is timed by a melting ice bone clock calibrated to a caribou's resting breath. The pacing would be...
