If they don't go all the way down ! We get some awsome fillets (reds )and sometimes Swallow a few ! Never had one stick half way ,what then ? Do they disolve ? For you pro fish eaters help me out I'm I m frying some for supper.(Called pin bones)

Pluck the pin bones that protrude from the fish after it’s cooked. Might not work very well if the fish is battered, I suppose. We grill most of our fish and the row of pin bones stack up maybe 1/8” and are relatively east to grab. My preferred method, rather than hacking them out prior to cooking.
Option two would be to chew slowly and find them before they go down the hatch, LOL.

I serve the rear half of the salmon to folks who don't know how to avoid pin bones; no pin bones in the back half.
