Preliminary Study of the Sonic Muscle of Micropogonias furnieri (Actinopterygii, Sciaenidae): Morfología e Histoquímica

The present study highlights the morphology of the Micropogonias furnieri sonic muscle by means of histochemical techniques, relating it to previous histochemical studies of the pectoral fin and myotomal muscles. In order to classify the muscle fibres, succinic dehydrogenase (SDH) for mitochondria,...
