Mineral balance of an invasive alga Caulerpa racemosa var. Cylindracea on the coast west of Algeria.


Our study was based on the demonstration of the water contents, of Chlorophylls a, Chlorophyll b, and Carotenoids, and of the mineral elements Na+, K+, Mg2+, Ca2+, in the thalli of the invasive alga Caulerpa racemosa var cylindracea harvested in eight stations located on the west coast of Algeria positioned on the Wilaya of AIN TEMOUCHANT; Sbiaat, the wilaya of ORAN; Bousfer, Kristel, Arzew, Mers el hadjadj, and the wilaya of MOSTAGANEM; Stidia, Salamander and Grove. The results obtained indicate a high water content for our thalli and high pigments contents compared for the stations studied, and significant contents in nutrients Na, Mg for the thalli from the different study sites marking a lack of element K by Na ratio by studying the Na/K ratio and a Ca level which is within the norms, which leads us to conclude that our species is rich in essential elements for its well being.
