We observed separating fish action. Subjects were a right-handed graduate student and a right-handed cerebral infracted patient. A graduate student separated dried horse mackereles two times by her right and left hand with chopsticks. A patient separated four times over 6 months by left 'nonparalysis' hand with also chop-sticks. We analyzed 6 actions video taped in these way : time, number of hand contacts with fish, number of functional acts that succeed to separate a piece of flesh. Contacts were divided in four sub-action categories, to separate fish, to separate bone or peel a skin, to put in order whole body and to arrange separated fleshes, bones and skins (see Table. 1). Organization of a sequential action process of these sub-action categories and an adjacent order of functional acts in each trials were showed Fig.1 to 12. Results showed that several anatomical structures of fish and variable action processes to separate fish were reciprocally determined and emerged a unique coordinated fish-action encounter.
