“…It is likely that the alteration of allele frequencies and genetic differentiation of L. calbasu populations in the Bhagirathi occurred during this period of restricted migration. Similar findings were seen in another Indian major carp, Cirrhinus mrigala, where the lack of genetic divergence in the Ganga population was evident with the exception of Bhagirathi samples that had small but significant genetic differentiation (Chauhan et al 2007). The significant genetic divergence between the Tons and Bihad rivers is of peculiar interest.…”

“…For fresh water fish species with wide distribution, however, higher observed heterozygosity is not uncommon. In another Indian major carp, Cirrhinus mrigala, Chauhan et al (2007) reported a range of 0.105-0.135 for observed heterozygosity. Among European cyprinids, the common, widespread roach Rutilus rutilus (L.) exhibits a high degree of variability (H e 0.097-0.124; Bouvet et al 1991), as did Leuciscus cephalus from the Central European Drainages (0.074-0.113; Hanfling and Brandl 1998).…”

“…This marker system provides an independent estimate of the level of variation within a population without an extensive morphological and quantitative account (Menezes et al 1993;Haniffa et al 2007). These markers have been successfully used to determine stock structure of several fish species (Lal et al 2004;Salini et al 2004;Chauhan et al 2007). The present study aims to identify polymorphic allozyme loci suitable for assessing and documenting the genetic variation and stock structure of wild L. calbasu accross its native distribution in India.…”

The population structure of Labeo calbasu from 11 rivers belonging to the Indus, Ganges, Bhima, Mahanadi, and Godavari basins was investigated using allozyme marker systems. Seven out of 20 allozyme loci (35%) were polymorphic (P < 0.99). Both probability and score tests indicated significant deviation of genotype proportions from Hardy-Weinberg expectations at two loci, XDH* (Mahanadi, Bhima, and Godavari) and G6PDH* (Mahanadi). A pairwise genetic homogeneity test and F (ST) values indicated a low-to-moderate level (0.0515) of genetic structuring in the wild population of L. calbasu. AMOVA analysis also indicated moderate differentiation among the samples from different river basins. Analysis for genetic bottleneck was performed under the infinite allele model. The study revealed nine genetic stocks of L. calbasu from the natural population across Indian rivers. Evidence of genetic bottlenecks in some rivers was also revealed.

“…Due to this, primers developed for a species from the flanking regions of a microsatellite locus can be used to amplify the same locus in other related species [17]. Primers developed for a species by this method have been successfully tested for ''cross-species amplification'' or ''cross-priming'' in its related species in several teleosts, including Asian cyprinids [41][42][43][44] and it Hob observed heterozygosity, Hex expected heterozygosity, Fis inbreeding coefficient, P HW probability value of significant deviation from HWE, A n mean number of alleles per locus, * significant at p \ 0.05, *** significant after Bonferroni adjustment was possible to obtain a set of useful markers for each study species by cross-priming.

Gonoproktopterus curmuca is an endangered red tailed barb found in Southern part of Western Ghat, India. As a part of stock-specific, propagation assisted rehabilitation and management program, polymorphic microsatellites markers were used to study the genetic diversity and population structure of this species from the three River systems of Southern Western Ghats, such as Periyar River, the Chalakkudy River, and the Chaliyar River. From selected eight polymorphic microsatellite markers, the number of alleles per locus ranged from 2 to 8, and the average number of alleles among 3 populations ranged from 5.0 to 5.75. The mean observed (H ob ) and expected (H ex ) heterozygosity ranged from 0.5148 to 0.5360 and from 0.5996 to 0.6067, respectively. Significant deviations from Hardy-Weinberg Equilibrium expectation were found at majority of the loci (except Gcur MFW72 and Gcur MFW19) and in all three populations in which heterozygote deficits were apparent. The analysis of molecular variance indicates that the percent of variance among populations and within populations were 6.73 and 93.27, respectively. The pairwise F ST values between populations indicate that there were significant deviations in genetic differentiations for the red-tailed barb populations from these three Rivers of the Western Ghats, India. The microsatellites methods reported a low degree of gene diversity and lack of genetic heterogeneity in the population of G. curmuca, which strongly emphasize the need of fishery management, conservation and rehabilitation of G. curmuca.

“…Therefore, low to moderate levels of genetic differentiation between the various river samples and paleogeographic reconstructions indicate the possibility that the C. chitala from different river basins sampled here are likely to have evolved from a common ancestral gene pool. A similar inference has been indicated by the low genetic variation found in the major Indian carp, Cirrhinus mrigala, a natural inhabitant of the Indo Gangetic rivers (Chauhan et al 2007). …”

Twenty-seven enzyme systems, six random amplified polymorphic DNA (RAPD) primers, and two microsatellite loci were tested to determine intraspecific divergence in the natural population of the endangered Indian featherback fish, Chitala chitala, for the first time. The 262 samples of C. chitala were collected from six riverine locations in India: the Satluj, Ganga (Ghagra, Bhagirathi, and Brahmaputra), Mahanadi, and Narmada river systems. The analysis revealed population subdivisions, with an F(ST) value from 0.1235 (95% confidence 0.0868-0.1621) for RAPD and a combined F(ST) of 0.0344 (95% confidence 0.0340-0.0350) for microsatellite loci. An analysis of 38 allozyme loci did not reveal any polymorphism in the samples from any of the riverine localities; a possible explanation for this could be that the ancestors of Chitala could have faced a population reduction in prehistoric periods, as low allozyme variation is also reported for other species of Chitala from south Asia.
