A PhD thesis at University of Basrah investigates the impact of sewage inflows on the composition of fish assemblages.

A PhD thesis in the College of Agriculture at the University of Basrah examined the effect of sewage inflows on the composition of fish assemblages in the Shatt Al-Basrah Canal.

The thesis of PhD student Kazem Hashem Hasan aims to identify the type of inflows and their impact on the canal's environmental characteristics, as well as to estimate the levels of heavy elements and their accumulation in the water, sediments, and muscles of resident fish.

The study concluded a decline in the number of freshwater species, dominance of marine species, and elevated levels of lead in the water and fish muscles studied, exceeding global standards. Using various diversity and pollution indices, it was determined that the nature of the Shatt Al-Basrah Canal is in a constant state of change due to increased pollutant concentrations.
