BIOREMEDIATION POTENCY OF PROBIOTICS ON CADMIUM POLLUTION TO IMPROVE FISH REPRODUCTIVE HEALTHALFIAH HAYATI, AGUS SUPRIYANTO, LISTIJANI SUHARGO, SUHAILAH HAYAZA1 AND ADAMU AYUBUAbstract This study aims to evaluate the potential of probiotics to remediate Cadmium (Cd) pollution in order to restore fish reproductive health. Thirty-six mature gonad male tilapia were divided into 12 groups which were determined based on variations in Cd concentration and supplementary feeds (probiotics, vitamin C, and a combination of both). Therefore, in this study, supplementation of probiotics, vitamin C, and combination of both were provided to repair the size of testicular cells that damage due to cadmium exposure. The parameters evaluated were the size of the testicular cells, including the thickness of the testis layer, the length of the seminiferous tubules, the diameter of the cyst, and the diameter of the germ cells. The results showed that giving supplementary feeds significantly improved testicular cell size (testicular layer density, seminiferous tubule length, cyst diameter, and germ cell diameter) contaminated by Cd. Probiotic supplements showed a better effect than other supplements on restoring the reproductive health of Cd-contaminated fish. |
