What Is a Jonah Crab?

A Jonah crab (Cancer borealis) is a cold-water North Atlantic crab with sweet, firm, flaky meat and big black-tipped claws. For years it was thrown back as lobster bycatch, and now it is prized on its own. If you have eaten a crab cake or a crab dip in New England lately, there is a good chance it was Jonah.

This guide covers what a Jonah crab actually is, what it tastes like, how the meat compares to snow crab, lobster, Dungeness, and king crab, how the fishery is managed, and how to buy and cook it. The short version: it eats like a premium crab at an underdog price.

TL;DR

• Jonah crab (Cancer borealis) is a sweet, firm North Atlantic crab with big black-tipped claws.
• It was once tossed back as lobster-trap bycatch and is now a managed, targeted fishery.
• The taste is sweet and mild, in the same range as snow crab or Dungeness, with the claws as the prize.
• Most home cooks buy it as picked meat, cooked and flash-frozen, ready for cakes, dips, pasta, or salad.
• It is already cooked, so warm it gently to about 140°F or serve it cold.

Why was Jonah crab once thrown back?

For years, Jonah crab was an afterthought. Lobster boats along the North Atlantic hauled them up in the same traps, and most went right back over the side until demand for the sweet meat grew. Per NOAA Fisheries, it shifted from incidental lobster-trap bycatch to a targeted fishery, and the Atlantic States Marine Fisheries Commission set up its first Interstate Fishery Management Plan in 2015, with federal-waters rules following. Landings climbed from under 3 million pounds in the 1990s to a peak above 17 million pounds around 2017 and 2018, and ran about 12.4 million pounds worth roughly 14 million dollars in 2023. A crab once discarded is now a catch worth chasing.

What kind of crab is a Jonah crab?

Jonah crab is the species Cancer borealis, living in the Northwest Atlantic from Canada down to Florida, with most of the harvest coming from south of Massachusetts and Rhode Island. It has a round, reddish-brown shell with rough, tooth-like edges and a pair of large claws tipped in dark brown or black. These are not small crabs: males reach up to about 9 inches across and typically weigh one to two pounds, and the claws are the prize, packed with the firm meat most people are after.

What does Jonah crab taste like?

Sweet and mild, with a firm, flaky texture. If you know snow crab or Dungeness, Jonah lands in the same friendly, approachable range: clearly crab, not fishy, easy to like, and the claw meat is a little denser than lobster and reads as slightly sweeter to a lot of people. It also happens to be lean, a strong source of protein and low in saturated fat, which makes it an easy centerpiece for a lighter dinner.

How does Jonah crab compare to other crab and lobster?

Snow crab has long, slender legs and slightly sweeter, stringier meat, so if you like cracking legs it is fun, while Jonah is claw-forward with a firmer bite and big pieces of sweet claw meat (our Jonah crab vs snow crab guide breaks that down in full). Lobster shares the same cold water and often the same trap: lobster meat is a touch firmer and richer, Jonah is sweeter and flakier, and many people who love our claw and knuckle lobster meat keep Jonah crab in the freezer too, because it plays the same role for less money.

Two Pacific crabs come up in the same conversation. Dungeness has sweet meat with a faint nutty edge, spread between the body and the legs, so picking one takes patience, while Jonah puts most of its meat in two big claws for a much higher payoff per crack. King crab sits at the other end of the scale, with thick, meaty leg sections, a rich buttery bite, and a price to match, which is why Jonah, sweet and firm with far less ceremony, turns up in crab cakes and dips more often than king crab ever will.

How do you buy Jonah crab?

Most home cooks buy Jonah crab as picked meat rather than whole crabs, because the claws take real work to break down. Jonah reaches shoppers in a few forms that are not interchangeable: whole cooked crabs (mostly near the boats), whole claws (the common retail form), cocktail claws (claws with part of the shell removed and the pincer left on as a handle), and picked meat with no shell at all. Whole crabs and claws mean cracking, a bowl for shells, and a share of the weight going in the bin, while cocktail claws are built for a platter and picked meat is edible to the last ounce.

Our Maine crab leg meat is wild-caught Jonah crab, already cooked, shelled, and flash-frozen, so you thaw it and it is ready for crab cakes, dips, pasta, or a cold salad. If a recipe calls for crab and you would rather not build a shell pile on the table, that is the form to buy.

What is the meat like to cook with?

Jonah crab holds its shape, which is the practical reason cooks reach for it: the pieces stay in recognizable chunks in a crab cake instead of collapsing into paste, and they survive a gentle toss in a hot pan without shredding. Two habits make a real difference. Drain thawed crab well and press it lightly in a sieve, because carried water thins a dip and makes cakes fall apart, and salt at the end rather than the start, since crab brings its own salinity from the sea.

Because the meat arrives cooked, treat heat as a finishing step. Melt 2 tablespoons of butter over low heat, add the crab, and toss for 2 to 3 minutes until it reaches about 140°F, then stop. It needs no heat at all in a cold crab roll, a chilled salad with lemon and chives, or a bowl of crab piled on buttered toast.

How is the Jonah crab fishery managed?

Jonah crab is caught in traps, the same gear that catches Maine lobster, often on the same boats and trips. Trap fishing is selective by nature: you haul, you keep what is legal, and undersized crabs go back over the side alive. The ASMFC Interstate Fishery Management Plan, in place since 2015 with federal-waters rules following, put permit requirements and minimum size limits around a catch that had been loosely tracked before, which is what turns a bycatch species into one that can be fished on purpose without running it down. For a shopper, the takeaway is short: wild-caught Jonah crab is a managed domestic fishery that travels a short distance from trap to table, and our guide to lobster sustainability covers how these North Atlantic trap fisheries are managed.

Why does Jonah crab cost less than it eats like?

Jonah crab is priced like an underdog for reasons that have nothing to do with quality. It spent decades as the byproduct of a fishery chasing something else, so it never built the name recognition that sets king crab and snow crab prices. The route to your kitchen is short, too: it is landed on the East Coast and processed close to where it is caught, without the long import chain some crab travels, and fewer steps between trap and freezer tend to show up in the price. What you get for that price is sweet, firm meat in pieces big enough to be the point of the dish rather than a garnish, and the gap between what it costs and what it tastes like is the whole case for keeping a bag of it in the freezer.

How do you thaw and store Jonah crab?

Frozen crab meat is patient, but thawed crab is not. Move it from the freezer to the fridge about 24 hours before you want it, or seal the bag and hold it in cold water for 30 to 60 minutes, changing the water about every 30 minutes, if you are in a hurry. Never thaw it on the counter. Once thawed, keep it at 40°F or below and use it within about 2 days, draining the liquid before you cook, and you can refreeze it only if it thawed in the fridge and never got warm. Portion before you thaw, since a pound of picked meat is enough for four crab rolls; if you need half of that, split the bag while it is still frozen and put the rest straight back in the freezer.

Try it for yourself

Jonah crab is the easiest way to get sweet, firm, claw-forward crab meat without the cracking, and it costs less than the crabs it eats like. Maine Shelled Lobster's wild-caught Jonah crab leg meat arrives cooked, shelled, and flash-frozen, so you thaw it, drain it, and fold it into cakes, dips, pasta, or a cold roll. Keep a bag in the freezer and dinner is a few minutes away.
