Sagitta otoliths of five species Scomberoides commersonnianus (414), S. lysan (15), S. tala (8), S. tol (344) and Megalaspis cordyla (277) were collected from the commercial catches from July 2013 to March 2015. Fish length and otolith length for five species recorded as S. commersonnianus TLcm = 16.3−88.4, OLcm = 0.3−0.9; S. lysan TL=23.2−73, OL = 0.2−0.7; S. tala TL = 48.5−55.5, OL = 0.6-0.9; S. tol TL =18.9−68, OL =0.3− M. cordyla TL= 18.4−47, OL = 0.3−0.9. The otolith dimensions such as length, height, weight were plotted against fish body parameters length and weights. The regression models estimate for otolith dimensions and fish body parameters estimates can be useful for studies on population structure of five important carangids species.
