Study of population genetic polymorphism and gene flow rate in Indian snow trout, Schizothorax richardsonii fish of Himalaya, India.

PubMed (2014)

Sivaraman Gk Ashoktaru Barat Ali S Mahanta Pc

The genetic polymorphism and gene flow rate among the Indian snow trout fish population S. richadsonii from three different locations viz., Chirapani stream of Champawat district, Kosi and Gola river of Nainital district, Uttarakhand State, India were assessed by employing twenty numbers of Randomly Amplified Polymorphic DNA (RAPD) markers. The overall percent polymorphisms among these three populations were 14.76 with 6.56, 4.92 and 3.28 in Chirapani, Kosi and Gola river population, respectively. Chirapani population had higher proportion of polymorphic loci as compared to the Kosi and Gola. The higher value of genetic distance (0.1565) was obtained between Chirapani and Gola population and the lower value of genetic distance was observed between Chirapani and Kosi (0.1058) river population. The cluster analysis revealed that in the formation of two clusters, one consisted of Chirapani and Kosi and the other was Gola fish population. Gst estimates among these populations showed some extent of homogeneity with lower genetic differentiation rate between populations and further suggested that higher tolerance to mutation, as expected that RAPD bands, arose from both coding and non-coding DNA regions. The findings revealed that the rate of gene flow in three populations seemed very low i.e. highly conserved its genetic diversity in their natural waterbodies and indicative of little migration among populations (geographically isolated and not the possibilities man made interventions/introduction of similar kind of fish species). It is further concluded that the Chirapani, Kosi and Gola river populations of S. richardsonii were being conserved naturally in their habitat and the species actual genetic potential were being maintained (adaptation to local climatic conditions, reproduction, production traits and disease resistance trait etc) in their natural habitat.

Karyotype of a New Loach <i>Schistura obliquofascia</i>and a Mahseer <i>Puntius chelynoides</i> from Kumaun Hills of Himalaya

CYTOLOGIA (2014)

Rohit Kumar Prabhati Kumari Sahoo Waikhom Vishwanath Ashoktaru Barat

The karyotypical analysis of two fish species, Schistura obliquofascia and Puntius chelynoides, from the Kumaun Himalayan Rivers was carried out to ascertain the taxonomic position of the species. The diploid chromosome number in S. obliquofascia was ascertained to be 2n = 50 with a karyotype of 2n = 20 metacentric (m), 20 submetacentric (sm), 6 subtelocentric (st) and 4 telocentric (t) chromosomes, and a fundamental arm number (FN) of 90, where as in P. chelynoides, the diploid chromosome number was 100 with a karyotypic formula of 2n = 26m+16sm+18st+40t with a fundamental arm number (FN) of 142. No sex chromosome pair was identified in the form of a heteromorphic pair in either of the species. The relationship within closely related species for both the genus was also discussed using this chromosomal data.

Complete mitochondrial genome organization ofTor putitora

Mitochondrial DNA (2013)

Jyoti Sati Chirag Goel Rohit Kumar Shahnawaz Ali R. S. Patiyal

The complete mitochondrial genome of Tor putitora, an endemic coldwater fish of Himalayas was determined for the first time. The genome is 16,576 bp in length and consists of 13 protein coding genes, 22 tRNAs, 2 rRNA genes and 1 putative control region. The gene organization and its order were similar to other vertebrates. The overall base composition was; A: 31.9%, G: 15.6%, C: 27.5%, T: 25%, A + T content 56.9% and the G + C content 43.1%. The control region was also consisted of a microsatellite locus (TA) 13 between 16, 456 to 16, 481 bp. The present study will provide the rationale for the management and conservation of T. putitora.

Redescription of the Striped Catfish Mystus tengara (Hamilton, 1822) (Siluriformes: Bagridae), India

Journal of Threatened Taxa (2013)

Achom Darshan P. C. Mahanta Ashoktaru Barat Praveen Kumar

The Bagrid Catfish Mystus tengara was described from a pond located in India under the genus Pimelodus. The validity of the fish has been confused and has frequently been treated as a synonym of Mystus vittatus. In this study, the species is rediagnosed and redescribed on the basis of fresh material collected from the Ganga-Brahmaputra drainage. M. tengara is diagnosed from congeners in having a unique combination of the following characters: body with a distinct tympanic spot and four brown stripes which are separated by a pale narrow interspace; origin of adipose-fin not reaching the base of the last dorsal-fin ray, 31-42 gill rakers on first branchial arch, eye rounded with a diameter 19.0-23.8 % HL and dorsal spine length 12.3-17.2 % SL, maxillary barbel length 254.5-360.5 % HL. A key for the identification of Mystus species from Ganga-Bramaputra drainage is also provided.

Karyotypic Diversity Among Three Species of Garra (Family: Cyprinidae) from River Dikrong, Arunachal Pradesh, India

CYTOLOGIA (2007)

Prabhati Kumari Sahoo Prasanta Nanda Ashoktaru Barat

Karyotype analyses of 3 Garra species, G. gotyla gotyla (Gray), G. kempi Hora and G. lissorhynchus (McClelland) from Arunachal Pradesh, India, are presented. All the 3 species have a diploid chromosome number of 2n=50, but different karyotype formulae. The species-specific karyotypes were observed in the 3 species. It was also tried to draw a possible phylogenetic relationship among the 3 species.
