  The stock assessment, of Indian scad Decapterus russelli (Ruppell, 1830) from the northern Arabian Sea in Pakistan was evaluated. The samples of Indian scad (13300 specimens), ranging from 1-31 cm (FL) and 1-400 g (TW) were collected from the commercial fish landing center located at Karachi harbor. The parameters of fish length-weight relationship were calculated from the aggregated data as a=0.0323, b=2.66 with R2=0.954, indicating slightly negative allometric growth between the relationship. The length frequency samples from September 2013 to November 2014 was analyzed using FISAT II software, including the ELEFAN-I method. The growth parameters obtained using ELEFAN I was: L∞=32.55 cm, K=0.750 per year, t0=-0.678 with an Rn value of 0.220. Natural, total and fishing mortality M=1.42 per year, Z=3.84 per year at CI of 95% (CI=3.11-4.58) where F=2.422 per year and exploitation.. View More»
