Determination of arginine vasotocin (AVT) and isotocin (IT) in plasma of the red tilapia (oreochromis niloticus ) in two different salinity condition

Abstract

There were two types of experiments that were conducted in this study. First one is to determine the AVT (Arginine Vasotocin) and IT (Isotocin) in the plasma of the Tilapia, Oreochromis niloticus fish. Second experiment is to determine the amount of AVT and IT in the plasma and obtain the different levels of AVT and IT in different salinity. Result shows that there is AVT and IT neurohypophysial hormones in plasma of the Tilapia and from the effect of salinity graph, the conclusion is AVT and IT levels were increasing with respect of higher salinity.
