Length weight relationship and condition factor of snow trout, Schizothorax plagiostomus (Heckel, 1838) from Lidder River, Kashmir


Author(s): Muddasir Jan, Imtiaz Ahmed

Abstract: Length–weight relationships of fish Schizothorax plagiostomus were originally used to provide information on the condition of fish and to determine whether somatic growth was isometric or allometric. The study was carried out to study length-weight relationship and condition factor of snow trout, Schizothorax plagiostomus in river Lidder originating from Kashmir Himalaya of District Anantnag and the sampling duration was from July, 2013 to June, 2014.The length-weight relationship of Schizothorax plagiostomus were calculated for males, females and combined ones. The relationship was analysed using the formula W = a Lb which was further transformed into Log W =a +b log L. A total of 500 specimens comprising 250 males, 250 females with different size groups were studied. The equation obtained for males was; logW = 1.590+2.726 logL; for females; logW= 1.664+2.775logL and for combined ones: logW = 1.626 +2.750log L. Females show ʻbʼvalue more than males in Lidder River. Length-Weight relationship and condition factor showed that the growth of Schizothorax plagiostomus is quite satisfactory in river Lidder. The regression coefficient between males and females did not show any significant difference while significant difference could be noticed between males and between females (p<0.01). Studies on condition factor revealed that the fluctuations in K values can be attributed to the spawning cycle as well as feeding intensity.
