| This paper reports on a preliminary study carried out on gill tissues of two edible lagoon fish species, the yellowstripe goatfish (Mulloidichthys flavolineatus) and the flat head mullet (Mugil cephalus) from the Bay of Poudre d'Or, Mauritius, which is known to be contaminated with toxicants and sediments. Both light and scanning electron microscopic studies of the processed gills of these two fish species showed marked histological alterations. The pathologic lesions of the gills included ballooning dilatations or lamellar hyperemia; hypertrophy of the filament and lamellar cells; yperplasia of the filament and lamellar cells, and deformities of gill arches, filaments and lamellae. |
