Abstract

     This study aimed to investigate the impact of environmental factors on the density and distribution of zooplankton in the Kiteiban Canal, a branch of the Shatt al-Arab River in Basra Governorate, Iraq. Seasonal samples were collected from three stations between autumn 2024 and summer 2025, with key physicochemical parameters such as temperature, salinity, dissolved oxygen, nitrate, and phosphate analyzed. The results showed that the highest zooplankton density was recorded in spring, particularly at Station 3, due to optimal environmental conditions. A positive correlation was observed between nitrate concentration and zooplankton density, while phosphate showed no direct effect. These findings highlight the importance of monitoring seasonal changes to ensure the sustainability of the aquatic ecosystem in the region.
