Abstract

In this study to investigate the relationship between length and weight of Leaping Mullet (Chelon saliens) 177 fish samples (91 Female and 86 Male) of leaping mullet were caught by fin nets from June 2020 to July 2020. sex ratio of male to female was 1:1 that showed no significant difference between sex ratio of male and female in population (〖 x〗^2=0.141 , P > 0.05 ). Maximum total length and weight were 28 cm and 186 g for females, 22cm and 137 g for males. The length-weight relationship of female was W=0.0048 〖Tl〗^3.167 (r^2 = 0.78) and the length-weight relationship of male was W=0.0313 〖Tl〗^2.542 (r^2 = 0.80) and the total relationship was W=0.0123 〖Tl〗^2.856 ( r^2 = 0.78. ( The results showed negative allometric growth for males and isometric growth for both population and female groups (t-test,t_male=3.350,t_female=0.959,t_population=1.290 ,p<0.05)
