Horabagrus brachysoma (Gunther) an endemic, cultivable catfish belonging to
Family Bagridae is found in rivers originating from southern part of the
biodiversity hotspot - the Western Ghats. This species is categorized as
"endangered" based on latest IUCN criteria, due to restricted distribution, loss of
habitat, over exploitation, destructive fishing practices and trade (Anon., 1998).
... The species is shonlisted for taking up stock-specific, propagation-assisted
rehabilitation programme in rivers where it is naturally distributed. Information on
the basic genetic profile and stock structure, which is essential for the fishery
management, conservation and rehahilitation of this species, is lacking. Hence, the
present work was undenaken to identify molecular genetic markers like
allozymes, RAPD and microsatellites in H. braclrysoma and to use them in
analyzing the population genetic structure of this species, collected from three
geographically isolated river systems viz., Meenachil, Chalakkudy and
Nethravathi in South India.
... In allozymes, the screening was carried out to detect 25 enzymes, but only 14
showed their presence with scorable activity. Out of founeen enzymes studied, 12
enzymes were polymorphic and two enzymes were monomorphic. The founeen
enzymes yielded 25 scorable loci in all populations. A total of 33 alleles were
obtained in overall populations
