Abstract

This study was conducted to evaluate the potential hazardous associatd with
two different species of fresh water fish, bolti (Ti/apia ni/otica) and karmout (C/arias
sp < /em>.) caught from River Nile, Abbassa aquaculture and channel of Bahr EI-Bakar
(Sharkyia Governorate). Microbial contaminations and heavy metals levels were
determined in the fish and water collected from different sources as well as,
superoxide dismutase enzyme activity (SOD) in fish organs. The results showed that
water samples collected from channel of Bahr EI-Bakar were more polluted with heavy
metals such as (Pb, Cd, Mn and Cr) and microorganisms, followed by water samples
collected from Abbassa aquaculture, while, water samples collected from River Nile
were the lowest in contamination; similarly, fish samples caught from channel of Bahr
EI-Bakar were more polluted with heavy metals and microorganisms, followed by fish
samples caught from Abbassa aquaculture, then fish samples caught from River Nile.
Karmout fish was more polluted than bolti fish. Moreover, the liver of all fish sa-nples
caught from River Nile possessed the highest activity value of SOD.
