Genetic diversity and structure of six Populations of Wallago attu were studied from Jhelum River, Pakistan using five species specific microsatellites loci. Genotypic data of all the samples were generated through PCR amplification of targeted loci. A total of 23 alleles were found in 177 fish samples. All the microsatellite loci were found to be polymorphic. The mean FST value (0.0248) showed little genetic differentiation. The average observed heterozygosity values were measured in range from 0.3450 to 0.4400 whereas average expected heterozygosity ranging from 0.5363 to 0.5777 were recorded in all the population. Majority of examined loci significantly deviated (P<0.05) from Hardy Weinberg Equilibrium (HWE). Analysis of Molecular Variance (AMOVA) indicated that majority of the variation lies within the individuals (81.10%) than among the individuals with in populations (16.4%).The results showed genetic decline in this valuable fish resource. The findings of the present study will be helpful for management, conservation as well as least kinship selective breeding programs for W. attu.


Key words: Genetic Variation, Freshwater Shark, Population Structure, Molecular Marker.
