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.
