Method of processing of fish, for example salmon and related species, said method comprising the steps of - providing a live fish, - slaughtering the fish, - subjecting the fish or part of the fish to an electrical stimulation prior to at least a further processing step of the fish, and - wherein said at least one further processing step comprises the step of removing pin-bones from the fish or part of the fish. By subjecting the fish or part of the fish to the electrical stimulation it is achieved that the pin-bones can be removed without waiting for the normal rigor process to be concluded and the normal post-rigor state to be reached and further it is achieved that the pin-bones can still be removed satisfactorily, e.g. without breaking when being pulled etc., since the bonding of the bones are relieved by the electrical stimulation.
