ABSTRACT
The present study was carried out to document the liver histology of the fish
Siganus rivulatus caught from the coastal water of the Red sea at Jeddah, and to document
also any histopathological lesions and attribute these lesions to their causes. Parasitic
infection were observed in the liver of about 83% of the fish. The most noticeable
histopathological lesions were due to histopathological parasitic this parasitic infection and
the toxic effect of deteriatiry water quality due to presence of heavy metals which is
considered a big cause to the cellular damage. lesions were hepatocyte vacuolization and
ballooning degeneration cellular and coagulative necrosis, cellular infiltraion, granuloma
inflammation and bile duct proliferation.
