Morphometric Relationships of Nemipterus randalli (Russell, 1986) from İskenderun Bay

Abstract

In this study was aimed to describe the relationships between morphometric characters and total length of Nemipterus randalli. A total of 107 samples were collected from Iskenderun Bay in November 2018. The results show that estimates of total length of this species through of morphometric character are reliable. Linear regressions showed the best accuracy for all relationships between morphometric characters and total length. Among obtained relationships, the best fit was recorded between total length and head length, while the lowest value of coefficient of determination was also determined between total length and horizontal mouth gape. Establishing morphometric relationships can provide an alternative to back‐calculation of fish length and can provide information that aids in understanding complex relationships between predator and prey size. The equations generated to obtain the total length of the fish using morphometric character data can be used in dietary studies of top predators and in paleontological studies.
