چکیده

In order to estimate the fecundity, reproductive character and feeding habit of Liza parsia, 75 gravid females were collected from Pasur River different shrimp farms Khulna district. The equation for total length-body weight standard relationship species found be BW = 9.769 x TL - 101.4 (R² 0.883) 9.921 SL 77.19 0.865) respectively. condition factor ranged 10.12-15.05 having mean value 12.35+1.08. Fecundity parsia 56541 188860 fecundity was calculated as 122999±30035. Total gonad varied 5.41 18.41 g where left lobe ovary 2.78 9.57 right 2.63 9.25 g. 5.942±1.409 5.589±1.381 11.532±2.773 regression with length, body estimated F= -176359+16034.5 (R2=0.60), -132956+16059.9 (R2=0.57), -5595.3+1588.79 (R2=0.63), 9048.16+9881.27 GW (R2=0.83) length GW= -19.154+1.64 (R2=0.74) -1.78+0.16 (R2=0.80) GSI values obtained in present study between 7.90 17.61 14.20+1.65. stomach contents algae, diatoms, desmids, plant materials, annelids, crustacean, bivalves, fishes, detritus sand grains. Food items indicated that they are omnivorous its habits.
