College of Education for Pure Sciences Discusses the Impact of Physical and Chemical Properties on Fish Growth in a Scientific Seminar
The Department of Life Sciences at the College of Education for Pure Sciences, University of Samarra, discussed “The Impact of Certain Physical and Chemical Properties of Tigris River Water on the Growth and Vitality of Fish” in a scientific seminar presented by Assoc. Prof. Dr. Hisham Fadel Shaker.
The Hisham aimed to define the most significant physical and chemical properties of the Tigris River water, evaluate water quality, and determine the extent of water pollution by monitoring changes in the concentrations of these factors.
The lecturer identified various sources of pollution, such as the influx of pollutants resulting from floods, agricultural runoff, and the discharge of contaminated industrial wastewater and urban sewage into the river.
In the same context, the presenter pointed out the impact of power plants adjacent to the Tigris River and the existence of dams on the quality of the river’s water.
The seminar focused on highlighting the causes of pollution in the Tigris River, which have led to the deterioration of water quality.
This degradation has negatively affected fish health, particularly the respiratory, digestive, and reproductive systems, as well as gamete formation.
These factors consequently impact fertilization rates, hatching, and the life cycle of fish offspring, in addition to their effects on the physiological and biochemical functions of tissues and blood.
