The potential of probiotics of malozndialdehide and gonadosomatic index of Tilapia (Oreochromis Niloticus) after exposure of cadmium

Cadmium pollution originating from factory waste and human activities is very dangerous because it has high toxicity and becomes a threat for aquatic organisms including tilapia as an aquatic animal that is sensitive to heavy metal pollution. Cadmium contained in water will enter the body of fish and damage organs, one of which is the testes. It will affect the productivity of tilapia and harm the farmers. Therefore, in this study, supplementation of probiotics and vitamin C was provided to repair testicular damage due to cadmium exposure. The parameters evaluated included the level of malondialdehyde (MDA) and the gonadosomatic index (GSI). Based on data analysis of MDA levels and GSI values, it is known that supplementary feeding (probiotics, vitamin C, and a combination of both) has a positive effect on the value of GSI, but testicular MDA levels only feed with vitamin C that can provide a positive effect.
