MUHAMMED YAŞAR DÖRTBUDAK*, GÜLNAZ ÖZCAN**
Abstract:
The relationships between standard length (SL) and otolith length (OL), and width (OW) were examined for kais kingfish (Cyprinion kais Heckel, 1843) from Güçlükonak location of Tigris River. Sampling was carried out every month using nets from January to December 2015. Otolith samples for analysis were obtained from 135 specimens (101 females and 34 males). Standard length and otolith length measured for all fish and sex was identified. Samples consisted of fish varying in standard length from 6.0 to
14.8 cm, weight from 2.8 to 75.55 g and otolith length from 1.51 to 3.07 mm. The relationship between fish length (SL) and otolith length (OL) was as y=0.1596x +0.4445 (R2=0.7606), between fish length (SL) and otolith width (OW) was as y=0.1201x +0.5561 (R2=0.8155), between fish length (SL) and otolith weight (OWe) was as y=0.0003x -0.0017 (R2=0.7632), between otolith length (OL) and otolith width (OW) was as y=0.6655x +0.4192 (R2=0.8385). Analysis for the relation between right and left otolith did not reveal any significant differences (t-test, p>0.05).
