| 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, periodic acid Schiff (PAS) for glycogen, Sudan Black and Red for lipids and myosin adenosine triphosphatase (m-ATPase) pre-incubated at alkaline and acid pHs to visualize the contraction velocity, were used. The sonic fibres were smaller than the white myotomal and pectoral fibres, showed homogenous size and distribution and had features common to white fibres: negative to SDH and lipids, weakly positive to PAS and m-ATPase following acid pre-incubation, and... |

| ABSTRACT The adductor pectoral fin muscle in post-spawning females of the white croaker Micropogonias furnieri (Desmarest, 1823) is described from a morphological, histochemical and morphometric perspectives. A description of the morphological characteristics was conducted after dissections in different layers, down to the deep layer. Five muscles were found: superficial, medial, radial and deep adductors, and dorsal arrector. Their fibers were studied after applying histochemical techniques: succinic dehydrogenase (SDH) to reveal mitochondria, periodic acid-Schiff (PAS) for glycogen, Sudan black for lipids, myosin adenosinetriphosphatase (mATPase) to reveal the types of fibers, and modified mATPase to evidence the capillaries. Fiber diameters were... |
