Genetic similarity and diversity of catfish Clarias batrachus (Linn.1758) populations collected from three regions of Indian riverine system were examined using randomly amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR). Out of 22 random primers tested, six primers produced 462 RAPD bands ranging from 105 to 128 polymorphic bands per primer in(More)
Mitochondrial DNA, cytochrome oxidase-1 gene sequences were analyzed for species identification and phylogenetic relationship among the very high food value and commercially important Indian carangid fish species. Sequence analysis of COI gene very clearly indicated that all the 28 fish species fell into five distinct groups, which are genetically distant(More)
This study describes the species diversity of fishes of the Narmada River in India. A total of 820 fish specimens were collected from 17 sampling locations across the whole river basin. Fish were taxonomically classified into one of 90 possible species based on morphological characters, and then DNA barcoding was employed using COI gene sequences as a(More)
Present study deals with the production of low cost salted and dried product from anchovy fish (Stolephorus spp.) using traditional technology application of different inhibitory factors to achieve a reasonable shelf life at ambient tropical temperature. Microbial safety, nutrient retention and product quality in terms of flavor and texture after(More)
Snakes represent a taxonomically underdeveloped group of animals in India with a lack of experts and incomplete taxonomic descriptions being the main deterrents to advances in this area. Molecular taxonomic approaches using DNA barcoding could aid in snake identification as well as studies of biodiversity. Here a non-invasive sampling method using DNA(More)
Grouper species of Epinephelus - E. epistictus, E. heniochus, E. latifasciatus, E. magniscuttis and E. radiatus exhibit overlapping colour pattern that often leads to misidentification in the field. Even the colour pattern of juveniles of these species in different size groups varies considerably with that of adults. DNA barcoding of these five species was(More)
India's third longest river, the Narmada, is studied here for the potential effects on native fish populations of river fragmentation due to various barriers including dams and a waterfall. The species we studied include a cyprinid fish, Catla catla, and a mastacembelid, Mastacembelus armatus, both of which are found in the Narmada. Our goal was to use DNA(More)
Excessive wildlife hunting for commercial purposes can have negative impacts on biodiversity and may result in species extinction. To ensure compliance with legal statutes, forensic identification approaches relying on molecular markers may be used to identify the species of origin of animal material from hairs, claw, blood, bone, or meat. Using this(More)
The clariid catfish, Clarias batrachus commonly known as Magur, has declined drastically from natural habitats in India during the last decade. This fish is highly preferred fish by Indian consumers and has high market demand. As a result traders often substitute C. batrachus with a morphologically similar but supposedly banned exotic catfish, C.(More)
The Asian catfish, Clarias batrachus (Linnaeus, 1758), is a highly valued species endemic to India that is currently in drastic decline in most of its natural habitat. The present study was undertaken to document the genetic structure of populations of this species using mitochondrial DNA markers, specifically from the cytochrome B and D-loop regions.(More)
