The IUCN classifies two-endemic fishes of the Western Ghats in Peninsular India: Nilgiri mystus Hemibagrus punctatus is critically endangered, and Yellow catfish Horabagrus brachysoma is vulnerable. These are threatened by habitat degradation, excess fishing, and dam construction. ICAR-NBFGR, the premier research organisation in India for fish conservation, aims to conserve these two species through captive propagation, stock identification, and stock-specific ranching programs.

Background: Hemibagrus punctatus (Jerdon, 1849) is a critically endangered bagrid catfish endemic to the Western Ghats of India, whose population is declining due to anthropogenic activities. The current study aims to compare the mitogenome of H. punctatus with that of other Bagrid catfishes and provide insights into their evolutionary relationships.

Genus Parapenaeopsis constitute an important fishery resource in Indian waters. Parapenaeopsis stylifera, being morphologically very similar to Parapenaeopsis coromandelica, mainly differentiated using telsonic armature and it is subject of controversy regarding the number of armature for the species. The present study was aimed to resolve the taxonomic ambiguity between P.

Macrobrachium rosenbergii, giant freshwater prawn, is one of the most commercially important crustaceans. In the present study, primers for ATPase 6/8 region of mt-DNA were designed and successfully amplified (827 bp) in the species. The nucleotide variation in ATPase 6/8 gene revealed the population structuring in natural populations of M.

In the present study three species of mackerel, Rastrelliger present in Indian waters were taken for genetic identification using cytochrome c oxidase subunit I and 16s rRNA sequences. Accurate identification of these species is important for fishery management as its morphological characters are very similar. In this study, the sequences of COI and 16S rRNA were determined from 19 individuals of three Rastrelliger species, Rastrelliger kanagurta, Rastrelliger brachysoma and Rastrelliger faughni from Andamans and Indian mainland to study the phylogenetic relationship.

The golden anchovy, Coilia dussumieri, though possessing discontinuous distribution along northeast and northwest coasts of India, it is being managed as unit stock for fishery assessment purposes. By considering the need for stock specific management of the species, mitochondrial ATP synthase 6 and 8 (ATPase 6/8) genes were analyzed for delineating genetic stock structure of the species. Sequence analysis revealed a total of 34 haplotypes across four populations from both the east and west coasts of India.

Silver pomfret, Pampus argenteus is an economically important seafood species. The fishery resource of pomfret in Indian waters shows a dwindling catch since the last few years and the pomfrets caught were mostly undersized which calls for immediate attempts for management of resources. An accurate definition of population structure is important for management of this species.

Murrels (Perciformes; Channidei; Channidae) are unique group of freshwater air breathing fishes having a confined distribution to African and Asian continents. The phylogenetic relationship among eight Channid species viz. Channa aurantimaculata, Channa bleheri, Channa diplogramma, Channa gachua, Channa marulius, Channa punctatus, Channa stewartii and Channa striatus were investigated using RAPD markers.
