Investigation of Morphometric Characteristics of Sagitta Otolith inFour Species of Fishes in the Coral Reefs of Persian Gulf and Oman Sea

This study aimed to Comparison of morphometric characteristics of otolith in Lutjanus lutjanusLutjanus malabaricusLutjanus erythropterusPomacanthus asfur in the coral reefs of Persian Gulf and Oman Sea. Sampling lasted from March 2014 to April 2015. During this period 6 specimens of Lutjanus lutjanus, 8 specimens of Lutjanus malabaricus, 5 specimens of Lutjanus erythropterus and 5 specimens of Pomacanthus asfur were cut with diving method. All the fish were identified and their otolith was extracted to verify them. Investigation of otolith morphometric characteristics (length, breadth, weight, perimeter and area) was conducted. Data indicate high correlation between otolith length and otolith weight, fork length and otolith length and between fish length and weight in most of species, The highest correlation was observed in L. malabaricus. The results show significantly different between otolith length and Otolith width in all species (pL. malabaricus and P. asfurbut not in L. lutjanus andL. erythropterus(p>0.05). Otolith weight had no significantly different in L. lutjanus and L. malabaricus and also in L. erythropterus andP. asfur(p>0.05) but had significantly different between those group... .
