To describe length-weight relationship in Acanthopagrus berda (Forsskal, 1775), its 1687 specimens (male, female and unsexed) were examined during the period from January 2005 to December 2006. The samples were obtained from three main landing centers of Karachi (Pakistan). The Fish Harbour, Ibrahim Haidary and 100 Quarters Korangi Karachi. Because most of the marine fish catch from Sindh and Balochistan provinces of Pakistan were brought to these centers for auction. The maximum size of male was 33.8 cm and the maximum size of female was 34.7 cm. The body weight ranged from 77.0 to 900g in case of male and 128 – 932.38g in female samples. The fork length (cm) and weight (g) relationship was described statistically using SPSS ver. 14. The values of “a” and “b” were determined by log10 transformed length and weight values. The relationship of length and weight was subjected to t- test analysis at p < 0.001. The magnitude of correlation coefficient (r²) for male specimens was 0.879, for female specimens 0.882 and overall (males, females and unsexed) 0.979. The magnitude of ‘b’ was near theoretical value of 3 in overall cases (isometry) and significantly different in male and female samples (negative allometry).
