“…Factor analysis could be useful to separate the stocks of B. bendelisis. DFA was also demonstrated successfully by Ahmad Mir, Iqbal Mir, and Chandra (2014); Barat et al (2013); Mir, Saxena, Singh Patiyal, and Kumari Sahoo (2015); Khan, Miyan, and Khan (2013); and Verma, Kashyap, and Serajuddin (2014). Recently, a study on phenotypic variation of B. bendelisis in four rivers from central Indian Himalaya was conducted by Iqbal Mir et al (2015) and they found significant difference in the head region, the middle portion and the caudal region.…”

“…Variations could also be partly explained by dietary shifts, influencing prey selection and catch efficiency . Ahmad Mir et al (2014); Bagherian andRahmani (2009) andMir, Sarkar, Dwivedi, Gusain, andJena (2013) were also of the opinion that high water velocity leads to change in body shape. This can be one of the reasons in influencing the body shape of this species as the sampling sites in Teesta River of Sikkim had very fast flow in comparison to Kameng and Myntudu river of Arunachal Pradesh and Meghalaya, respectively.…”

The present study explains the intraspecific variation in Indian Hill trout (Barilius bendelisis) on the basis of image based truss network system and D‐loop region of mtDNA. A total of 210 samples were collected from three different rivers (Teesta, Kameng and Myntudu River) of North East India in Indo‐Burma Biodiversity Hotspot. By using the software applications (tpsDig version 2.1 and PAST), a total of 25 morphometric measurements were generated from 10 landmarks. The Analysis of Variance (ANOVA), Factor Analysis (FA) and Discriminate Function Analysis (DFA) showed, out of the total variations, factor 1 explained 46.74% while factor 2 and factor 3 explained 27.14% and 11.92%, respectively. Using these variables 83.33% of the cross‐validated specimens were classified into distinct groups. Analysis of Molecular Variance (AMOVA) and pairwise Fst value for D‐loop region of mtDNA also showed high to medium level of genetic variation among the stocks and within the stocks. We conclude that the observed discrete stocks might be the result of changing environmental conditions in different rivers of the hotspot as the rivers are present at different altitudinal labels. It is also believed that the variation might be due to the construction of barrages across the river which hinder the mixing among the stocks.

“…Those characters reflect the swimming, feeding and foraging ability of the fish. The variation in the caudal region of specimens from the six water bodies could be a consequence of phenotypic plasticity of fish in response to uncommon hydrological conditions (Mir et al, 2013).…”

Asala or snow trout (Schizothorax richardsonii, Cyprinidae), one of highly valued freshwater fish of Transhimalayan regions, is distributed in upper reaches of all major river systems of Nepal. Morphometric diversification between six river populations of S. richardsonii was examined to identify intraspecific unit for enabling better management of the resources. Significant differences were observed in 17 measured morphometric characters of 207 specimens among the six river populations. Multivariate analysis of variance (Wilks' test) indicated a significant difference for mean vectors of mophometric measurements (? =0.012, F85, 731 = 19.999, P<0.0001) among populations. Principal component and discriminant functions (DFs) analysis of morphometric measurements revealed high seperation of the stocks. The analysis showed that most of the shape and size variation among these populations occurs in the head region, body depth and fin length. Apparent morphometric divergence among S. richardsonii samples showed the existence of three differentiated groups viz., the Indrawati and Khudi populations, the Melamchi and Phalaku Rivers, and the Sabha and Tadi River populations of Nepal. The results of this study may be useful in fisheries management and potential exploitation of this species in coldwater aquaculture.Int J Appl Sci Biotechnol, Vol 3(3): 464-473

“…Ducks have better adaptation to various environmental conditions compared to chickens. However, the biological relationships among the morphometric traits may be different if these body measurements are treated as bivariates rather than multi-variates (Eyduran et al 2010;Mir et al 2014). This is because simple correlation only allows an assessment of the magnitude and direction of the association between the two characters, without providing the necessary information relating to direct and indirect effects of a group of characters in relation to a dependent variable of the greatest importance (Lorentz et al 2011 (Neto et al 2012).…”

The study aimed at describing objectively the interdependence between body weight (BWT) and morphometric traits in Khaki Campbell and Pekin ducks using multivariate path analysis technique.Measurements were taken on one hundred and ninety seven (197) randomly selected 10-week old Khaki Campbell and Pekin ducks, respectively in Plateau State, Nigeria. The birds were reared on deep litter in a semi-intensive system where they were kept in a fenced area provided with water ponds and locked up in the poultry house during the night. The body parts measured were, body length (
