Wild vs Farmed Sashimi in Korea, How to Tell Them Apart and Why the Prices Differ

The biggest differences are how firm the flesh is and how long the finish lasts. A fish that grew up swimming in the open sea has dense muscle, so it pushes back when you chew, and after you swallow the sweetness rises slowly. A fish raised on feed in a tank has softer flesh with its fat spread evenly, so it sits easily in the mouth from the very first slice. Neither one can be called the better fish. At a Jagalchi sashimi restaurant, eight out of ten guests spot the wild one on the first bite, saying "this one is chewier", yet when the two plates are mixed together, half of them cannot tell the difference with a fatty species like olive flounder. The Jagalchi ajimae, with more than ten years of experience, always gives guests the same advice. If you want firmness and a long finish, choose wild, and if you want softness and evenly spread fat, choose farmed. With a species like sea bream the gap is clear, while with olive flounder and rockfish it tends to be small, so the answer depends on the species. Dipping heavily in vinegared chili paste buries the whole difference, so when you compare, use just a touch of salt or soy sauce.

For first-time sashimi eaters and for family or company dinners, farmed sashimi is the right fit. There are three reasons. The flesh is soft, so children and older guests chew it easily, there is little fishy edge, so even without chili paste nobody balks at it, and the price stays the same all year, so once the headcount is set the bill is settled. The assorted platter at this Jagalchi Haean-ro restaurant is built on olive flounder, rockfish and sea bream, and farming is stable for these species, so the slices come out about the same thickness whatever the season you visit. Weekend evenings at 7 PM are the busiest hour, and most of the four-person family tables arriving then order the medium assorted platter at KRW 80,000 (about USD 58). Company dinners work the same way. When a group of more than ten goes all wild, the price swings a lot depending on the day of the species and the person collecting the money is stuck, but the assorted platter on fixed-size pricing is set at KRW 120,000 (about USD 87) for the extra large, which makes budgeting easy. The idea that farmed fish is a lower grade does not hold up on the ground at Jagalchi. It simply has a different use. People need a soft first experience before they go looking for the firmer one next time.

Laying one slice each of the same species side by side and eating them without chili paste is the fastest way to compare. The order goes like this. Dip one slice of farmed olive flounder lightly in salt and count how many times you chew, then right after that chew one slice of wild olive flounder the same way. If it takes three or four more chews, that is the difference in muscle. After swallowing, wait about ten seconds and compare the sweetness left in your mouth, and you can see the length of the finish. At this Jagalchi Haean-ro restaurant, ask for one slice of wild fish to be added on top of your assorted platter and the whole comparison is done on a single plate. The species guests use most for comparing is sea bream, and since the gap is clear there, even beginners notice it at once. Salmon, on the other hand, needs no comparison. The salmon that comes into Jagalchi is almost all farmed, and for that species the fattier side is actually the right one. Compare with white-flesh fish. Also take a sip of water before moving to the second slice, so the fat from the first one does not cloud your judgment.

Wild fish costs more because the catch differs every day, moving fish while still alive is expensive, and some fish die along the way. Farmed fish raised to plan in tanks carries none of those three burdens, so its price can be fixed. That is why the assorted platter at this Jagalchi Haean-ro restaurant runs on fixed-size pricing, small KRW 60,000 (about USD 43), medium KRW 80,000 (about USD 58), large KRW 100,000 (about USD 72) and extra large KRW 120,000 (about USD 87), while premium wild sashimi is quoted from KRW 80,000 at a daily selection price. The daily selection price means picking, among the species that came in that day, the one with the best condition of flesh, and setting the price to match that build. On days when spotted halibut (ishigari) or roughscale sole comes in, the price moves up, and on days built mostly around red sea bream it comes down. The wild price not being printed as a fixed number on the menu is not a trick but a result of this structure. If the price feels like a stretch, you can add just one wild slice on top of the assorted platter. Most guests get their first taste this way. Before ordering, a single question, "what wild fish do you have today?", brings out the species of the day and the price right away.

With olive flounder, look at the belly. A wild olive flounder has a plain white belly with no markings, while a farmed one often keeps dark blue-green blotches on its belly. A fish that roamed a wide sea floor grows up with a clean belly, while a fish that lay flat on the bottom of a tank for a long time has color soak into its belly. Ask at the tank for the flounder to be turned over and you can check it right there. This is the question guests ask most often in front of the tanks outside Jagalchi sashimi restaurants, so the vendors are used to it. This method works only for olive flounder, though. Sea bream, rockfish and black rockfish (bollak) are not sorted by belly color, and for those species you can only make a rough guess from whether the fins are intact and how deep the body color is. Once it has been sliced into sashimi, you cannot judge even olive flounder by its belly. At that point, go back to the chew-count comparison from the previous section. If you are not sure, just ask. A place that posts fixed-size prices has no reason to hide the origin or whether a fish is farmed.

To order, you only need to say two things, your headcount and the purpose of the meal. Sujeong Hoejib runs both a standard farmed assorted platter and premium wild sashimi, so for everyday meals, families and company dinners it points you to the assorted platter (small KRW 60,000 to extra large KRW 120,000, fixed-size pricing), and for anniversaries or hosting guests to premium wild sashimi (from KRW 80,000, daily selection price). If you want to compare the two, ask for one wild slice to be added to the assorted platter. The side dishes change daily, built mostly around whatever is freshest. The restaurant is 220m from Exit 2 of Jagalchi Station on Busan Metro Line 1, toward Jagalchi Haean-ro, about a 3-minute walk, and three stops from Busan Station on Line 1. With 190 seats across the ground and second floors it can host group dinners, and for four or more, a call ahead to +82-10-8998-4803 will even tell you which wild species are in that day. Avoid lunch from 11:30 to 13:00 and dinner from 18:30 to 20:00 and you can sit down without waiting. Whichever you choose, the meal carries on to a spicy stew simmered from the bones or a bowl of rice, so there is no need to worry about leaving hungry after ordering only sashimi.
