FECUNDITY OF LIZA PARSIA (HAMILTON) AND RELATIONSHIP BETWEEN LENGTH-WEIGHT AND FECUNDITY

Abstract

The fecundity of Liza parsia (Hamilton) was estimated studying 80 gravid females collected from the local markets in Khulna during November 2007 to January 2008. The fecundity ranged from 37,675 (total length 15.5 cm, body weight 39.791 g and ovary weight 3.532 g) to 1,87,442 (total length 21.8 cm, body weight 118.8 g and ovary weight 18.421 g). The mean fecundity was calculated to be 91269.29±35501.09. The mean weight of the ovary was 8.657±3.458 g while that of left and right lobes were 4.467±1.823 g and 4.192±1.667 g respectively. The diameter of the eggs of left lobe ranged from 0.42-0.72 mm while that of the egg from right lobe was 0.42-0.75 mm. The regression equation for total length and fecundity, standard length and fecundity, body weight and fecundity, ovary weight and fecundity was estimated to be (R2=0.69), (R2=0.69), (R2=0.76) and (R2=0.90), respectively while that for total length and ovary weight, standard length and ovary weight, body weight and ovary weight was (R2=0.74), (R2=0.75) and (R2=0.83), respectively. The linear relationship was highly significant in all the above cases.
