DNA barcoding has been adopted as a global bio-identification system for animals in recent years. A major national programme on DNA barcoding of fish and marine life was initiated in India by the authors during 2006 and 115 species of marine fish covering Carangids, Clupeids, Scombrids, Groupers, Sciaenids, Silverbellies, Mullids, Polynemids and Silurids(More)
Random amplified polymorphic DNA (RAPD) and microsatellite markers were applied to evaluate the genetic variation in endemic and endangered yellow catfish, Horabagrus brachysoma sampled from three geographic locations of Western Ghat, South India river systems. In RAPD, of 32 10-mer RAPD primers screened initially, 10 were chosen and used in a comparative(More)
A new cell line [pearlspot fin (PSF)] has been developed from caudal fin of Etroplus suratensis, a brackish/freshwater fish cultivated in India. The cell line was maintained in Leibovitz's L-15 supplemented with 10% fetal bovine serum (FBS). The PSF cell line consisted predominantly of epithelial-like cells. The cells were able to grow at temperatures(More)
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. rosenbergii in(More)
The partial sequences of 16S rRNA and cytochrome c oxidase subunit I (COI) mitochondrial genes were analyzed for species identification and phylogenetic relationships among the commercially important Indian sciaenids (Otolithes cuvieri, Otolithes ruber, Johnius dussumieri, Johnius elongatus, Johnieops vogleri, Otolithoides biauritus and Protonibea(More)
The two species of yellow catfish, Horabagrus brachysoma and H. nigricollaris are categorized as 'endangered' and 'critically endangered' respectively in their wild habitat. Proper knowledge of genetic structure and variability of these endangered species are highly essential for the management, conservation and improvement of fish stocks. Therefore,(More)
The Puntius denisonii colloquially and more popularly referred to as Miss Kerala is a subtropical fish belonging to the genus Puntius (Barb) and family Cyprinidae. Two cell lines PDF and PDH were developed from the caudal fin and heart of P. denisonii, respectively. The cell lines were optimally maintained at 26°C in Leibovitz-15 medium supplemented with(More)
The black tiger shrimp (Penaeus monodon), a commercially important penaeid species, is widely distributed across the Indo-Pacific region. Genetic diversity in P. monodon collected from eight geographical regions in Southwest, East and Andaman coastal waters of India (N=418) was investigated using 10 polymorphic microsatellite loci. Average observed(More)
Samples of the spotted murrel (Channa punctatus) were collected from three rivers of Tamil Nadu and Kerala. The allozyme variation of C. punctatus was investigated by polyacrylamide gel electrophoresis. Eighteen enzymes were detected, but only 10 (EST, PGM, G3PDH, G6PDH, SOD, GPI, ODH, GDH, XDH, and CK) showed consistent phenotypic variations. Allele(More)
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(More)
