This depends on the fish you are buying. It’s always a good idea to check any fillet for bones, even ours. We do inspect each fillet thoroughly, but we are only human. Some fillets are cut so that bones are included. The nape and first 3 to 4 inches on most fillets is where you will find bones. Some fish do have pin bones that run down the center of the fillet, and these can be easily removed with tweezers.
