Abstract

Otolith morphology analysis is one of the main tools used for fish or stock identification Moreover otolith shape can also be used in the fish feeding studies stomach content for the identification of prey fish and their size according to the relationship between fish and otolith sizes In the present study the relationship between fish length and otolith morphological dimensions was investigated for Sargocentron spiniferum Forssk l 1775 family Holocentridae The samples 185 fish and 370 sagittal otoliths were collected from the coast of the Red Sea Egypt The statistical analysis was undertaken in two steps using generalized linear models for the relationship between body length and weight and otolith morphology descriptors length width area and perimeter and shape indices aspect ratio compactness form factor rectangularity roundness ellipticity squareness sulcus and ostium From the relationships between total length TL of fish and fourteen morphology descriptors and shape indices three are significantly correlated with TL otolith length cauda and squareness where the side effect were p 0 05 The our results provide more information for the relationship between otolith morphometric and fish length
