Resumo: | 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 measured and the number of capillaries was counted. Fiber subtypes named small, medium and large were found within red, pink and white fibers, the latter prevailing. Staining homogeneity was observed in white fibers after alkaline pre-incubations. The number of capillaries decreased from red to white fibers. Due to the prevalence of white fibers, the adductor muscle of the pectoral fins appears to be capable of rapid and discontinuous movements, which are important to body stabilization during subcarangiform swimming. The homogenous staining of white fibers observed in this research corresponds to the post-spawning gonad stage studied. |

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 measured and the number of capillaries was counted. Fiber subtypes named small, medium and large were found within red, pink and white fibers, the latter prevailing. Staining homogeneity was observed in white fibers after alkaline pre-incubations. The number of capillaries decreased from red to white fibers. Due to the prevalence of white fibers, the adductor muscle of the pectoral fins appears to be capable of rapid and discontinuous movements, which are important to body stabilization during subcarangiform swimming. The homogenous staining of white fibers observed in this research corresponds to the post-spawning gonad stage studied. |
