Abstract Cultivated mullet fish mere compared with the fisheries mullet fish from four locations during summer and winter 2005/2006. This work was evaluated via chemical analysis of feed, water, sediments and fish besides their contents of three heavy metals and three pathogenic microbial genera. from the foregoing results, it could be concluded that there is pollution with heavy metals (particularly with iron and lead) and pathogenic bacteria (specially E. coli) 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 metals pollution and 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. |
