Sardinella sindensis is economically the most important small pelagic fish species in the coastal area of Jask. Population dynamics of Sind sardinella from the Jask coastal waters, during April 2000 to December 2001 was studied. The asymptotic length (Loo) and growth coefficient (K) were estimated as 19.5(cm) and 1.18(yr-l) respectively. The minimum and maximum T.L. was recorded 62 and 188 (mm) respectively. The value of to was calculated -0.15, and Tmax was estimated 2.5 year. The growth equation of Von Bertalanffy was obtained at L (t) = 19.5(1- exp (-1.18(t-(-0.15))) for this species. Total mortality (Z) rate was estimated 3.92(yr-l) (r2=0.99) on Length-converted catch curve method. The rates of natural mortality (M) on Paulyʹs empirical equation, fishing mortality (F) and exploitation ratio were estimated 1.14 (yr-1), 2.78 (yr-1) and 0.71 respectively. Four cohorts were distinguished annualy on Bhattacharyaʹs method with mean length 73, 99, 136 and 169 mm. Maximum recruitment was in May at 26.64 percent. The length-weight relationship was determined as W= 0.00001 L 29524.
