If you wish to inspect this yourself, you can always go fishing for them around the Pacific Ocean.

Did you know...

The Halibut fish has a variety of names all across the world. The Japanese call them the Hirame fish, while the Spanish refer to this species as Falso halibut Del.   The French, on the other hand, call them Cardeau Hirame. Therefore, this species has many different names across Japanese, Korean, and Chinese lands, and other locations. A large Olive Flounder is worth 800 bells!

Do people eat Olive Flounder?

The Flatfish species is a gourmet delicacy, earlier available only in Korea, China, and Japan, but now, is enjoyed by people across the world, even in the western hemisphere. The Cardeau species is well-loved by all, especially in Asian countries like Korea, which were the first to mass breed this sea species for commercial benefit. Though the exact price of an Olive Flounder vary from location to location, you can be sure that it is an expensive penny to pay. This is because they used to be an incredibly rare breed, which is now well known only because of aquaculture.

However, if you do not wish to pay for acquaculture, fishing is always an option! They are a large catch, and a testament to your skill if you ever catch this large, unwieldy fish across the north and south-western Pacific. You can catch them off Japanese and Korean shores, with a long fishing pole and plenty of bait attached to it. They live in-depth, so getting this large fish may not be easy.

How do Flounders become 'flatfish'?

Due to constantly staying at the bottom of the sea, this species from Korea endures great pressure on its body daily and has adapted itself accordingly. As soon as 30 days after their hatching, they turn on their side, and their side now becomes their belly, and their eyes shift away to accommodate this change. Now officially on their side,  aquaculture now calls them the "flat" fish.
