    Abstract: The study of genetic diversity between Rainbow trout and Snow trout were done by using random amplified polymorphic DNA technique. The 5 RAPD primers generated a total 68 consistently scorable bands size ranging from 220-2018 bp. The percentage of polymorphic loci observed to be 17.65 % for Rainbow trout and 35.29 % for Snow trout. According to polymorphic loci the amount of genetic variation between the two species was Rainbow trout < Snow trout from low to high. The higher genetic diversity was found within the Snow trout population (0.1332), and lower genetic diversity was found for the Rainbow trout (0.0755). The Shannon index ranged from 0.1087 (Rainbow trout) to 0.1963 (Snow trout).
