Abstract
The histological effect of crude petroleum oil on the intestine of lignose emperor "Lethrinus elongates" was investigated. Exposing fish to 50 and 100 p.p.m of crude oil induced many histopathological alterations. The epithelium of the mucosal folds showed marked discontinuity with many eroded tips and the cell boundaries were ill-defined. The muscular layer exhibited severe fragmentation and degeneration. Moreover, the general mucosal epithelial layer showed apparent decrease in the treated fish. It is speculated that one or more of the crude oil hydrocarbons are responsible for the observed histopathological effects.
