Morphometry and length-weight relationship of Schizopyge niger from Kashmir

Abstract

Schizopyge niger locally called as “Ale gad”, is a prized commercial fish of Kashmir found abundantly in the valley lakes. The present investigation was carried out to study the morphometry of the fish using conventional methods and to establish the length-weight relationship. High correlation coefficient (R2) values were obtained in the study (0.4497-0.8264) indicating high degree of relationship between the different morphometric characters compared. The length-weight relationship was established logarithmically as LogW= -3.4361+2.3827 LogL. The correlation coefficient (R2) was obtained at 0.6568, indicating strong correlation between the two parameters. The growth coefficient (b) value was estimated at 2.3827 indicating negative allometric growth pattern for S. niger.
