Salmon bone typically refers to the skeletal structure found within a salmon fish. It is composed of a backbone, which runs down the center of the fish, as well as smaller pin bones. They are thin, translucent, and somewhat flexible. They present a significant choking hazard if accidentally consumed and are usually removed during preparation or cooking process. Salmon bones, though often discarded, can be used to add extra flavor to dishes such as broths and stews, when boiled over a long time, extracting the nutrients from the bones into the broth. Some cultures also consume them deep-fried until crispy. For those looking to extract maximum health benefits from the fish, salmon bones are rich in calcium, omega-3 fatty acids, and other nutrients.

Salmon bones are not common in all grocery stores. Your best bet would be to check in the seafood department if it's a large store. Some Asian or specialty markets might carry them. Alternatively, you can ask a fishmonger or the seafood counter at your local grocery store if they have salmon bones. Sometimes, they don't display them, but they do have them in their storage.
