Abstract—The present study demonstrates the influence of serotonin (5-HT) and dopamine (DA) on gonadosomatic index (GSI), oocyte diameter (OD) and hepatosomatic index (HSI); histology of the ovary; total lipid, triglycerides, free fatty acids and lipase activity in the hepatopancreas and ovaries of Macrobrachium rosenbergii. Injection of 5-HT and DA significantly increased and decreased the gonadosomatic index, oocyte diameter and hepatosomatic index respectively. Similarly, 5-HT and DA injections increased and decreased total lipid and triglycerides respectively in the hepatopancreas and ovary. However, 5-HT injection decreased free fatty acid and lipase activity while DA injection increased free fatty acids and lipase activity in the hepatopancreas and ovary. Histological observations of the ovary, showed that while 5-HT increases ovarian maturation with regard to arrangement and enlargement of oocytes in oogonia of the ovary, DA was found to cause decreased effect on the same. Present results clearly showed the involvement of 5-HT and DA in the regulation of ovarian maturation in M.rosenbergii. 

Index Terms—gonadosomatic index (GSI), oocyte diameter (OD), hepatosomatic index (HSI), total lipid (TL), lipase activity (LA), M. rosenbergii
