Study impact of Nutrients (NO3-, PO4-3, SiO4-3) on Phytoplankton Growth in laboratory at commercial port of Lattakia city During autumn.
Abstract
In this study, we investigate phytoplankton behavior applying Mesocosm experiments to clarify the changes in their growth under High temperature and different nutrients concentrations
(e.g. NO3-, PO4-3, SiO4-3).Using unfiltered seawater, the samples were collected from two different marine stations during November 2023. The amount of nutrients consumed by phytoplankton was studied, the Chl a changes were identified and the specific composition of Phytoplankton and abundance was determined. Results showed that during the nutrient enrichment experiment, no increase in phytoplankton growth was recorded when nutrient concentrations were tripled on their natural concentrations, This was reflected in the poor consumption of nutrients, the concentrations of which remained until the end of the cuddling period. Diatoms were the fastest to consume nutrients in all the circles used and the following species prevailed:
(Thalassiosira decipiens, and, Pseudo-nitzschia delicatissima Nitzschia closterium) throughout the period of cuddling.
