Length-Weight Relationship and Breeding Biology of <I>Puntius conchonius</I> (Hamilton, 1822) from Dal Lake, Kashmir

Abstract

The length-weight relationship and fecundity of Puntius conchonius were investigated on samples collected from Dal Lake, Kashmir. The analysis of this fish species was based on 150 specimens ranging in size from 38mm to 84mm and in weight from 1.42g to 10.712g. The regression values obtained for male, female and for pooled sexes (2.97, 2.93 and 2.94). The regression co-efficient was found to depart significantly from the cubic value. The computed value of correlation coefficient (r) for males, females and pooled ones were as r=9.22, r=9.36 and r=9.35 respectively, which were closer to 1 indicating that there is high positive correlation between the two variables i.e.length and weight.
The fecundity studies on Puntius conchonius revealed that there is a relationship between length of the fish with fecundity, weight of the fish and ovary with fecundity. The length and fecundity exhibited a straight line relationship between fecundity and body weight. Fecundity and ovary weight also exhibited linear relationship.
