Abstract A histopathological survey was conducted to investigate the presence of microparasites in fish Archosargus probatocephalus in a river near Maceió, Brazil. Light microscope observations of fragments of gill showed the presence of small cysts containing numerous myxospores that were morphological...

Pereira, Bruno Fiorelini; Pitol, Dimítrius Leonardo; Caetano, Flávio Henrique.

Int. j. morphol; 37 (1), 2019

SUMMARY: Morphological and physiological responses of gills exposed to environmental contaminants are widely described in the literature. Among the primary findings are the lamellar fusion, hyperplasia, aneurysms, proliferation of mitochondria-rich cells and mucous cells. This work has as main objectives...

The purpose of the current investigation was to describe the gill morphology of two bottom feeders Mediterranean Sea fishes: Striped red mullet fish (M. surmuletus) and grey gurnard fish (E. gurnardus) that showed the same feeding habits. The gill system of the grey gurnard consisted of four pairs of gil...

Surface ultrastructure of the gills of Odontesthes bonariensis (Valenciennes, 1835)(Teleostei: Atheriniformes) from a temperate shallow lake

Tano de la Hoz, María Florencia; Longo, María Victoria; Escalante, Alicia Haydée; Díaz, Alcira Ofelia.

Int. j. morphol; 32 (4), 2014

We studied the gill epithelium of juveniles of Odontesthes bonariensis using scanning electron microscopy with a particular interest in the relationship between cell morphology and the different functional aspects of gills. The specimens used were collected in Laguna de los Padres, Buenos Aires Province,...
