Length-weight Relationship and Relative Condition Factor (Kn) of Silver Pomfret, Pampus argenteus in Pakistani Waters

Abstract

In this study, we present length-weight relationship and relative condition factor in silver pomfret, Pampus argenteus sampled during July 2010 to November 2011 in Pakistan. In the samples standard length (SL) was ranged 6.8-21. 8 cm and total weight 9.4-450 g was registered. In length-weigh relationship exponent b=3.51 value indicated that the fish growth is positive allometric. The coefficient of determination R^2=0.96 value showed a strong correlation between the variables. The relative condition factor Kn were characterized in eight size classes. The mean Kn values range 0.75-1.15 highest was in 12.0-13.9 size classes and lowest 0.75 in the size class of 20.0-21.9. The t-test value was 9.102, P＜0.0001). Our findings shall pave a way for baseline information about an important fish species from this area and are similar to those reported from its distribution.
