Software:Article Title: Eco-morphology of sagittal otoliths in five Macrouridae species from Central Mediterranean Sea.
Article Snippet: .. Shaper R (open-source software package running on R version 4.0.5, RStudio 2022.07.1 Build 554; R Gui 4.1.3 2022.03.10) was used to perform the otolith shape analysis, being a specific package for the investigation of the Table 1 The calculated shape indexes, OL is otolith length (mm), OH is otolith height (mm), OP is otolith perimeter (mm), OS is otolith surface (mm2), SP is sulcus acusticus perimeter (mm), SS is sulcus acusticus surface (mm2), SL is sulcus acusticus length (mm), CL is cauda length (mm), CW is cauda width (mm), OSL is ostium length (mm) and OSW is ostium width (mm) Shape Indexes Formulas Circularity OP2/OS Rectangularity OS/(OL × OH) Ellipticity (OL–OH)/(OL + OH) Aspect Ratio OH/OL Form Factor 4πOS/OP2 Roundness 4OS/πOL2 Otolith Length to Total Fish Length Ratio OL/TL Sulcus Acusticus Surface to Otolith Surface Ratio SS/OS Cauda Length to Sulcus Acusticus Length Ratio CL/SL Ostium Length to Sulcus Acusticus Length Ratio OSL/SL intra and inter specific otoliths shape variability [79]. .. ImageJ software (version 1.53 k freely available at https:// imagej. nih. gov/ ij/) was used to calibrate each image of the distal sagittae faces by determining, through the measure and setscale functions, how many pixels 1 mm corresponds based on the magnification used.
