Abstract
The salt work of Sfax (southern Tunisia) is a potential site for the exploitation and production of local Artemia. Significant quantities of Artemia (cysts and biomass) are harvested each year and are used in larval feeding. Since this salt work is surrounded by several sources of emissions and pollution, assessing the quality of the cysts and biomass of Artemia, is of great importance. To this end the determination of some toxic trace metals: mercury (Hg), cadmium (Cd), lead (Pb), copper (Cu), and zinc (Zn) was performed. The analyses of these metals were carried out by atomic absorption spectrometry. The results obtained showed that the concentrations in both cysts and biomass are low compared to those recorded for other strains that have already been commercialized and are used in fish farming. Thus, Artemia from the salt work of Sfax could be used without chemical risks in the feeding of fish larvae. [ABSTRACT FROM AUTHOR]
