Length-weight relationships of two sympatric species (Knipowitschia byblisia Ahnelt, 2011 and K.caunosi Ahnelt, 2011) in Koycegiz Lake, Turkey

Abstract

This study provides basic information on length-weight relationships for Knipowitschia byblisia Ahnelt, 2011 and Knipowitschia caunosi Ahnelt, 2011, two endemic species of Koycegiz Lake Basin (Southern-West of Turkey). Samplings were carried out seasonally from 2014 to 2015 by means of beach seine nets with mesh sizes from 10 to 35mm. A total of 343 individuals from the two fish species were examined, with more specimens belonging to K.byblisa (90.4%). The total length-weight relationships were calculated as: W=0.0054 TL(3.384)for K.byblisia and W=0.0058 TL(3.417)for K.caunosi, respectively.
