A study on length-weight relationships of Scatophagus argus (family: Scatophagidae) from Karachi coast, Pakistan

A study on length-weight relationships of Scatophagus argus was carried out during January 2015 to December 2015. A total of 282 specimens of different sizes were collected from the fish harbours of West Wharf and Korangi Creek, Pakistan. The b-value of regression equation shows the positive allometric growth in juveniles and adults of S. argus while, the negative allometric growth was obtained for combined fishes. The coefficient of correlation (r) was found as 0.992, 0.985 and 0.996 showing strong correlation between length and weight of juvenile, adult and combined fishes, respectively. All results were found significant at 5% significance level.
