    In this study, structural properties, shapes and types of motor nerve terminals of tail muscles were observed by the light microscopy. In the light of the examinations of slides taken from 7 different muscles of tail region, it was observed that, m. lateralis superficialis was formed by small diameter red muscle fibers whereas the larger part of the other 6 muscles were formed by large diameter white fibers. Meanwhile, intermediate type muscle fibers were found among these muscles. In addition to them, small, triangled myosatellite cells were observed, too. It has been established that the innervation of the red muscle fibers of m. lateralis superficialis occured by multiple and end plate type. White muscle fibers which are extensively found in the other muscles of the tail in trout, except m. lilteralis superficialis are innervated by multiple and end grappe type nerve terminals. Also, it has been determined that endomysium had positive AChE activity only in white muscle fibres in other regions except nerve terminals.
