Length-weight relationships of four snowtrout species from the Kashmir Valley in India

Abstract

SummaryLength-weight relationships (LWR) are presented for one species of the genus Schizopyge [S. curvifrons (Heckel, 1838)] and three species of the genus Schizothorax [S. esocinus (Heckel, 1838), S. labiatus (McClelland, 1842) and S. plagiostomus (Heckel, 1838)] from different water bodies of the Kashmir Valley, India. A total of 774 specimens were sampled and measured from January to November 2011. No information regarding LWRs of these species was available in FishBase.

Length-weight relationship of five commercially important freshwater fish species in the Kashmir Valley, India

“…Khan and Sabah (2013) reported values of b for Schizopyge niger (2.66), Schizothorax curvifrons (2.69) and Schizothorax plagiostomus (2.86) from the Jhelum River and Dal Lake in Kashmir valley, which is lower than observed in present study. Mir et al (2014) also reported lower b values for Schizothorax curvifrons (2.81) and Schizothorax plagiostomus (2.60) in comparison to our study. For Glyptosternon reticulatum, the observed b value is 3.124, which is within the expected range of Froese and Pauly (2015).…”

Length Weight Relationship (LWR) and Condition Factor (K) of Brown Trout, Salmo trutta fario

“…Length-weight relationship of fishes is an important aspect in fisheries and fish biology because it is used in estimation of the average weight of the fish of a given length group by estab-lishing a mathematical relation between them 21,17,18 . The length weight data has two main purposes; it helps to express the relationships between length and weight, so that one of them can be converted into another.…”

Length-weight relationships of the Indian Major Carp, Labeo rohita (Cypriniformes: Cyprinidae) from six drainages of Ganga basin, India

“…Además, la gama de coeficiente de determinación (r 2 ) en los hombres se registró desde 0,978 a 0,989 y para las mujeres que iba desde 0,958 a 0,985. Los datos generados en la presente investigación serán útiles para el biólogo pesquero y agencias de conservación en el manejo y conservación de las poblaciones silvestres de esta especie.Palabras clave: relación talla-peso; río Ganges; crecimiento; silvestre; India.The length-weight relationships (LWR) of fishes are important in fisheries biology because they allow the estimation of the average weight of the fish of a given length group by establishing a mathematical relation between the two (Mir, Mir, Patiyal & Kumar, 2014). Like any other morphometric characters, the LWR can be used as a character for the differentiation of taxonomic units and the relationship changes with the various developmental events in life such as metamorphosis, growth and onset of maturity (Thomas et al, 2003).…”
