Description Not Available
The comparative assessment of genetic diversity using allozymes, ran dom amplified polymorphic DNA (RAPD), and microsatellite markers was con ducted in endemic and endangered yellow catfish (Horabagrus brachysoma)
sampled from three locations in Western Ghats river systems of India. Among the
three markers, microsatellites show more polymorphism, having 100% polymorphic
loci, whereas allozymes show the least (56%). In RAPD, 60.5% of fragments were
polymorphic. Observed heterozygosity and FST values were very high in micro satellites, compared with the other markers. Microsatellite and RAPD markers
reported a higher degree of genetic differentiation than allozymes among the
populations depicted by pairwise FST/GST, AMOVA, Nei’s genetic distance, and
UPGMA dendrogram. The three classes of markers demonstrated striking genetic
differentiation between pairs of H. brachysoma populations. The data emphasize the
need for fishery management, conservation, and rehabilitation of this species
