As a general guideline, here's an estimate of the number of pinbones in different types of salmon:
1. Chinook Salmon (King Salmon): Chinook salmon typically have around 140 to 180 pinbones.
2. Sockeye Salmon (Red Salmon): Sockeye salmon have approximately 120 to 140 pinbones.
3. Coho Salmon (Silver Salmon): Coho salmon have around 110 to 130 pinbones.
4. Pink Salmon (Humpback Salmon): Pink salmon have relatively fewer pinbones, usually ranging from 90 to 110.
5. Chum Salmon (Dog Salmon): Chum salmon have around 100 to 120 pinbones.
It's important to note that these numbers are approximate and can vary from fish to fish within the same species. Pinbones can be found along the backbone, as well as in the dorsal and anal fins.
When consuming salmon, it's recommended to be cautious and carefully remove any pinbones before eating to avoid any potential discomfort.
