Abstract

Cultivated mullet fish were compared with the wild mullet fish from four
locations during summer and winter 200582006. This work was evaluated via
examination of three pathogenic microbial genera (Saimonella. Shigella 8. E. coflr) in
samples of rearing water. aquafeed. sediments and fish. From the results. it could be
concluded that there is a pollution with pathogenic bacteria (specially E. coir) in all fish
feeds. rearing water and sediments of the tested locations (mainly in summer
season). Also. there is no difference between fish of natural resources and those of
aquaculture concerning bacterial contamination. So. it is a legal must to take
considerations from the responsible authorities for treating all kinds of waste waters
before reaching water bodies to protect aquatic life and consumers.
