The Sagitta otolith characteristics in 3 species viz. Sardinella gibbosa, S. longiceps and S. sindensis, of various standard lengths were compared. The results showed that these species have acquired peculiar characteristics which separate them from the other species. Likewise presence of two groups of characteristics: (1) characteristics that are consistent in the sagitta otoliths of S. gibbosa, S. longiceps and S. sindensis which are useful to separate these species from the rest of clupeids species, however these otolith characteristics in 3 species of Sardinella genus are more closely related to one another, (2) characteristics that vary due to genetically guided mechanism and biological factors but that may be useful to define species and are species-specific.
