Occurrence and length weight relationship of Indo-Pacific mugilid Chelon carinatus (Valenciennes 1836) in four river estuaries of Turkey

Abstract

Occurence and length-weight (LWR) relationships of four populations of&nbsp;<em>Chelon carinatus </em>in brackishwater systems of Mediterranean coast of Turkey were reported. A non-indigenous fish species, <em>C. carinatus </em>were captured between November 2014 and June 2017 in Ceyhan, Seyhan, G&ouml;ksu and Manavgat river estuaries. A total of 127 individuals, ranging in size between 11.8 and 20.8 cm total length, 19.0 and 113.6 g weight, were examined. The length&ndash;weight relationship for all individuals was described by the following parameters: <em>a</em> = 0.0076; <em>b</em> = 3.1708 and <em>r²</em> = 0.93. The results of the current length-weight relationship study show that there is significant difference from the isometric <em>b</em> (3.0) value for all these populations. The length-weight relationships from all localities were reported here for the first time.
