Determination of some heavy metals levels in common carp fingerlings fed with yeast

Abstract EN

This study was carried out at fish laboratory of Animal Production Department, Faculty of Agricultural Sciences, University of Sulaimaniya using commercial dry yeast in three concentration (0%, 3%, and 5%) for 12 weeks to study their effects on concentration of some heavy metals (namely Cr, Cd, Co, Pb, Cu, Fe, Zn, and Mg) of common carp fingerlings (Cyprinus carpio).

The experiment was included three treatments each in three replicates (plastic tanks) in which 10 fingerlings common carp of the same size and average weight (3.5 gram) were stocked in each aquarium.

The actual experimental feeding trials lasted three months.

Results indicated that the concentrations of heavy metals differ among the treatments.
