Relationship between Body and Otolith Morphological Characteristics of Sabre Squirrelfish (Sargocentron spiniferum) from the Southern Red Sea: Difference between Right and Left Otoliths

Otolith morphology analysis is one of the main tools used for fish or stock identification. Moreover, otolith shape can also be in animal dietary studies (stomach content) identification prey fishes and their size according to relationship between sizes. In present study, length morphological dimensions was investigated sabre squirrelfish, Sargocentron spiniferum (Forsskål, 1775) (family: Holocentridae). Samples 185 were collected from coast Red Sea, Egypt. To analyze otolith, morphometric measurements (length, width, area, perimeter, weight, sulcus, ostium) factors (aspect ratio, compactness, form factor, rectangularity, roundness, ellipticity, squareness) describing outline extracted using image analysis. Generalized linear models applied body each feature. From relationships total fourteen features, only length, caudal squareness significantly correlated with size. Our results provide more information features.
