Abstract
Analysis of fifteen morphometric measurements and their indices for Pagellus erythrinus and Pagellus acarne in the Egyptian Mediterranean waters revealed that in case of Pagellus erythrinus, body depth, girth, maxillary and pre-orbital
indices increase with increasing fish length, while forked length, inter-orbital and eye diameter indices show a decrease with increasing size. Pagellus acarne is characterized by the fact that pre-anal, body depth, girth, maxillary, pre-orbital and eye-diameter indices increase with increasing length. Comparative study of different morphometric indices and test of significance for both species showed that only pre-dorsal and pre-pectoral are significantly different at 5% level, while standard length, pre-anal, body depth, maxillary, girth, pre- orbital, postorbital and inter-orbital are highly significantly different at 1% level. The five (forked length, head length, dorsal, pre-ventral and eye-diameter) are non-significant.
Analysis of variance for meristic characters of Pagellus erythrinus showed that there are differences in pectoral fin ray count for fishes at the same length in different regions of the Mediterranean basin.
