“Fish ice cream” most commonly refers to one of two things: taiyaki, a Japanese fish-shaped waffle cone filled with ice cream, or akutaq, a traditional Alaskan Indigenous frozen dessert that actually contains fish. There’s also a smaller world of novelty and experimental fish-flavored ice creams. Which one you’ve encountered depends on where you saw it, so here’s a breakdown of each.
Taiyaki: The Fish-Shaped Waffle Cone
The version most people encounter at food festivals, social media feeds, and dessert shops is taiyaki ice cream. Despite the name, there is no actual fish in it. Taiyaki is a fish-shaped waffle cone, crispy on the outside and often filled with soft-serve ice cream, custard, or red bean paste. The fish shape comes from a traditional Japanese street snack that’s been made in cast-iron molds since the early 1900s. The modern ice cream version simply swaps out the classic filling for frozen dessert.
You’ll find taiyaki ice cream at Asian dessert shops across the United States, Canada, and Europe. It’s become a viral dessert trend, recognizable by its open-mouthed fish shape overflowing with colorful soft serve, fruit toppings, and sprinkles. If someone showed you a photo of “fish ice cream” and it looked Instagram-ready, this is almost certainly what it was.
Akutaq: Alaskan Ice Cream Made With Real Fish
Akutaq (sometimes spelled “agutuk”) is a genuinely fish-based frozen dessert, and it predates anything you’d find in a modern ice cream shop by centuries. Indigenous cultures of Alaska have made akutaq for generations, using whitefish, salmon, or pike as a base. The preparation involves boiling the fish, removing the bones, then squeezing it dry and whipping it together with fat, sugar, and berries. Traditional versions used seal oil or rendered animal fat; modern cooks often substitute vegetable shortening and evaporated milk.
The berries are central to the dish. Cooks fold in salmonberries, blueberries, blackberries, or wild red berries picked from the tundra, depending on what’s available and what they prefer. The result is a dense, creamy, whipped mixture that gets stored in a permafrost cellar or freezer until solid. It doesn’t taste like conventional ice cream. It’s richer, fattier, and has a texture closer to whipped mousse than scooped dairy ice cream.
A High-Energy Survival Food
Akutaq isn’t just a treat. Substituting dried meat for the berries creates a dense, high-fat, protein-rich version that sustained hunters during long trips in freezing temperatures. Once frozen, this version was cut into portable, power-bar-sized pieces of pemmican. Arctic explorers Admiral Peary and Dr. Frederick Cook relied on the same high-fat provisions when they trekked to the North Pole.
The dish also carries deep cultural significance. Large batches of akutaq have traditionally been prepared for memorial services, community gatherings, and everyday hospitality. As recently as a century ago, families kept frozen akutaq in permafrost cellars, ready for drop-in guests. During an 1842 gathering along the Yukon River, an akutaq cooking contest took place where couples competed to create the most inventive recipes, incorporating everything from fish eggs and bird eggs to caribou-stomach contents and beaver.
Nutritional Profile
A 100-gram serving of traditional fish-and-berry akutaq made with seal oil provides about 3.4 grams of protein and 0.53 grams of omega-3 fatty acids, which covers roughly a third of a typical daily omega-3 target. The calorie density is high by design. This is a food engineered by necessity for Arctic survival, not a light dessert.
Novelty Fish-Flavored Ice Cream
Japan has a small but real market for ice cream made with seafood. Flavors including crab, eel, octopus, and shrimp ice cream are all commercially available and accepted in Japanese markets. These are curiosity products, but they exist beyond the novelty stage in parts of East Asia.
Researchers at the University of Iceland and the Iran Fisheries Research Organization have also studied adding fish protein powder to conventional ice cream as a way to boost nutrition. In sensory tests, panelists couldn’t distinguish between ice cream made with 10 to 30 grams per kilogram of fish protein and a regular control sample. The catch: after about two months in frozen storage, the fish protein began breaking down, producing fishy off-flavors, rancid odors, and a grittier texture. Fresh batches tasted fine, but the product had a short shelf life before the fishiness became noticeable.
Where to Find Fish Ice Cream
Taiyaki ice cream is the easiest to find. Dedicated dessert shops in most major cities carry it, and Asian grocery delivery services sell packaged fish-shaped ice cream cones online. If you’re searching for akutaq, it’s far harder to come by outside of Alaska. It’s a homemade, community food, not a commercial product. Your best chance of tasting it is at an Alaskan cultural event, potlatch, or through personal connections with Indigenous communities. Japanese seafood-flavored ice cream is largely available only in Japan, though specialty importers occasionally carry it.
