Length-Weight Relationships and Fulton’s Condition Factor of Common carp (Cyprinus carpio L., 1758) from Tercan Dam Lake, Eastern Anatolia, Turkey

Abstract

In this study, length-weight relationships (LWR) and Fulton's condition factor (K) values of totally 190 Common carp, Cyprinus carpio L., 1758 specimens, captured from Tercan Dam Lake between May 2017-October 2017, were examined. Sex composition was 41.58 % (n=79) female and 58.42 % (n=111) male. Female to male sex ratio of the population was found as 1:0.71. Fork length and weight values of overall, female and male specimens ranged from 11.2-55.5 cm/30.2-2860.5 g, 11.2-55.5 cm/30.2-2860.5 g and 12.7-47.5 cm/44.6-1846.9 g, respectively. K values varied between 1.204 and 4.008. The average value of its was calculated as 2.155±0.041 for females, 2.138±0.046 for males and 2.148±0.030 for overall. The LWR were determined W= 0.0646*FL 2.6613 for females, W=0.0389*FL 2.8103 for males and W=0.0528*FL 2.7202 for overall. The values of b was estimated as 2.66 (females); 2.81 (males); 2.72 in overall. According to b value of LWR, the growth of C.carpio was negatif allometric (b<3, P<0.005). No information currently exists on the LWR of C.carpio in the Tercan Dam Lake, Eastern Anatolia, Turkey. Therefore, this paper is an important contribution to the fisheries management applications.
