“…Many authors reported that the gill chamber of most teleost fish was bounded laterally by the operculum which closing the ventrolaterally opened gill opening which different in its position and mechanism of action (Eiras-Stofella & Charvet- Almeida, 1997Almeida, , 2000Alsafy, 2013;Elsheikh, 2013). Our finding noted that, the gill cavity was bounded laterally by a three layered gill covering which consisting of; outer cutaneous layer and the middle bony supportive layer while the third internal layer is a muscular layer.…”

“…There are great variations in the number of gills between the different fish species; in the present study there are three pairs of gills, however, four pairs of gills is the common number in most teleost fishes (Hughes & Grimstone, 1965;Hughes & Morgan;Hossler et al, 1985;Eiras-Stofella et al, 2001;Eiras-Stofella & Fank-deCarvalho, 2002;Zayed & Mohamed;Cinar et al, 2009;Díaz et al, 2009;Kumari et al, 2009Kumari et al, , 2012Alsafy;Elsheikh). However, there are five pairs of gills but the fifth pair is ill developed and devoid from any gill filaments as noted in catfish (Zayed & Mohamed;Kumari et al, 2005;Elsheikh), in contrast, in Senegal sole (Arellano et al, 2004) reported that the fifth pair is well-developed and contain gill filaments.…”

“…In this regard, the three rows of gill rakers were also reported in catfish (Zayed & Mohamed) and in Clarias gariepinus (Elsheikh). Although, the presence of two rows of rakers on gill arches is common in many fishes (Hossler et al, 1985;Abuzinadah, 1995;Zayed & Mohamed;Salman et al;Díaz et al, 2009;Alsafy;Elsheikh).…”

SUMMARY:In the present study, we focused on the morphology of L. sceleratus gills using gross anatomy, scanning electron microscopy as well as light microscopy. Results of this study revealed that the gill openings appeared as simple slits anterior to the pectoral fin without distinct opercular cover. The gill system consisted of three pairs of gill arches carrying two rows of gill rakers on its concave border and gill filaments on its convex border. SEM showed that all surfaces of the gill arch were characterized by the presence of the longitudinal ridges with many taste buds in addition to many spines around the rakers. Histologically, the gill arch was composed of curved bar of hyaline cartilage with slightly elevated area corresponding to the sites of gill rakers. Each filament was formed of a thin central cartilaginous core surrounded by peripheral cartilaginous ma trix and covered by primary epithelial layer with abundant mucous cells. The chloride cells appeared mainly near to the base of secondary lamellae. Each gill filament gave rise to a very large number of secondary lamellae on both sides. The epithelial lining of the secondary lamellae comprised epithelial pavement cells, few mucous cells and pillar cells. The latter interposed the enriched blood capillaries. These findings suggest that L. sceleratus gills have characteristic morphological features that are related to adaptive functions for feeding habits, osmoregulation and respiratory mechanism with in their living environment.

“…The morphology of uninfected gills of the catfish Clarias gariepinus resembles that described for other teleost fish species (Wilson and Laurent 2002, Kearn 2004, Arafa et al 2009, Senger et al 2011, Elsheikh 2013. Each gill consists of a gill arch from which arise two rows of primary gill lamellae (gill filaments).…”

Surface ultrastructure of the gills of the angler catfish Chaca chaca was investigated to unravel the adaptive modifications associated with the feeding ecology of the fish. The fish is often found in mud or in soft substrates where they remain buried both for protection and to feed. Gill rakers present on the gill arch in most fish species are absent in this fish. The absence of gill rakers are associated with the feeding habit of the fish and is considered to facilitate the swallowing of captured prey smoothly without any hindrance. Highly corrugated surface of the gill arch and gill filaments could be associated to retain water/mucus to prevent dessicassion of the fish. Papillae like epithelial protuberances each bearing a taste bud at its summit toward the pharyngeal side of the gill arch is associated with the sorting of the food. Large number of mucous goblet cells on the gill arch epithelium are considered to secret copious mucus to lubricate the prey for easy swallowing. In C. chaca the gill septa between gill filaments are reduced. This could enhance the flexibility and permit the free movement of the gill filaments. Extensive secondary lamellae and infrequent mucous goblet cells on secondary lamellae are associated to increase the surface area to enhance efficiency of gaseous exchange.
