Effects of induced starvation on the histology of the fish skeletal muscle, have been studied in the "red muscle" of Heteropneustes fossilis. The tissue has been studied at weekly intervals, for four weeks. The intrafibrillar as well as the interfibrillar nuclei exhibit different behaviour in the red and the white muscle fibre types. Loss of myofibrils, predominantly in the white fibres, is accompanied with an increase in the non-contractile extrafibrillar tissue.
