“…Chloride cells are primary site of osmo-regulation in euryhaline fish. However, fish inhabiting in the freshwater possess chloride cells with wider apical surface, less evident crypts and less in abundance [19]. This observation agrees to the present study that showed a low occurrence of chloride cells.…”

The histology and surface ultra-structures of the gill epithelium of Labeo bata has been examined through light and electron microscopy. Gill arches bear double rows of primary lamellae and each primary lamella is provided with two rows of delicate rectangular secondary lamellae on its upper and lower surfaces. Gill arches and filaments are lined by thick stratified epithelium while the epithelium of secondary lamella is made up of thin single layered pavement cells. The thin epithelium is supported and kept apart from each other by the pillar cells. The pavement cells are polygonal with well-defined cell boundary and microridges on its apical surface. The epithelial cells are interspersed by large chloride cells located at the base of secondary lamellae and PAS positive mucous cells. Mucous cells are found abundant at the base and tip of the primary lamellae. Taste buds are found on the concave anterior faces of gill arches. The short and soft gill rakers are covered with stratified epithelium. This finding demonstrated that the fish has well developed respiratory system matching to its active life.

“…The prominent angle of curvature at the union of short epibranchials and long and extensive ceratobranchials, toward the dorsal side, closer to the neurocranium of the first to fourth pairs of gill arches, of R. rita has also been characteristically reported in other fish species with similar feeding habits. These include Plagioscion squamosissimus, an opportunistic carnivorous feeder, preferentially a fish eater (Mazon et al, 1998), Eugerres brasilianus, an omnivorous feeder, feeding mainly on small organisms (Eiras-Stofella and Charvet-Almeida, 2000), and Cathorops spixii, which feeds primarily on bivalves, shrimps, brittle stars, and worms (Eiras-Stofella and Fank-de-Carvalho, 2002). In contrast, gill arches either lack an angle of curvature in filter-feeding mullets Mugil cephalus (Hossler et al, 1979), M. curema, M. liza, andM.…”

Gill arches and the gill rakers of a sluggish, carnivorous catfish, Rita rita, show significant differences of their surface ultrastructure, which are recognized adaptive modifications in relation to food and feeding ecology of fish. Gill rakers on the first and second pairs of gill arches are borne on the oral side and are long and stout at the epi-ceratobranchial union. Gill rakers on the third and fourth pairs of gill arches, in contrast, are borne on the oral and aboral sides and are relatively delicate and short. Long and stout gill rakers on the first and second pairs of gill arches are considered primarily to prevent entry of undesirably large food items into the pharynx. Two types of taste buds, Type I and Type II, occur on the gill arches and the gill rakers. The raised taste buds, located at the apical ends of the gill rakers on the third, fourth, and the fifth pairs of gill arches could increase gustatory efficiency in the pharynx. Differences in the distribution of taste buds on the pharyngeal sides of different gill arches indicate that the posterior part of the pharynx plays a more crucial role in gustation than does the anterior part. Co-occurrence of teeth and taste buds on the epi- and hypopharyngeal bones denotes that food processing and gustation occur simultaneously in the pharynx. Villiform and caniform teeth on the epi- and hypopharyngeal bones are associated with a complex food-processing cycle. Mucous secretions, oozing through mucous cell openings, provide lubrication facilitating smooth passage of food through the pharynx. The angle of curvature at the epi-ceratobranchial union of the first to fourth pairs of gill arches could assist the ventral drag of ceratobranchials in lowering of the pharyngeal floor, thus resulting in a great expansion of the pharynx, as needed to accommodate the large quantities of food captured.

Surface Ultrastructure of the Gills of Odontesthes bonariensis (Valenciennes, 1835)(Teleostei: Atheriniformes) from a Temperate Shallow Lake

SUMMARY: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, Argentina. The gill filaments or primary lamellae are arranged in two rows along the convex outer face of the gill arch forming the anterior and posterior hemibranchiae. On its concave inner face, each arch supports two rows of gill rakers forming the pharyngeal region wall. The primary lamellae are lined by a stratified epithelium made up of polygonal cells with well-defined outlines and cell membrane microfolds. Several mucous and chloride cells were observed in the primary lamellae. The epithelial cells of the secondary lamellae have ill-defined outlines and few microfolds. Both the arches and gill rakers are covered by a stratified epithelium of polygonal cells, among which mucous cells and taste corpuscles are abundant. The ultrastructural analysis of gills of O. bonariensis contributes to the advancement of knowledge of the organ histophysiology and of future histopathological studies.
