Some Reproductive Characteristics of the Beysehir Dace (Squalius anatolicus Bogutskaya, 1997) in Oymapınar Dam Lake Antalya, Turkey

Abstract

This study was conducted in Oymapınar Dam Lake from March 2016 to February 2017. The study investigated the age composition, spawning season, sex ratio, first sexual maturity, and fecundity of chub (S. anatolicus). The ages of the 422 chubs sampled from Oymapınar Dam Lake ranged from II to VIII of which 200 (47.39%) were females and 222 (52.61%) were males. The fork lengths and weights of female chubs varied between 20.0 cm and 55.1 cm and 93.37 g and 2307.88 g respectively. The oldest age group was VIII for females and VII for males. The length at first sexual maturity for females and males were 26.0 cm and 23.0 cm, respectively and the age at first sexual maturity for females and males were III and II, respectively. This shows that males mature earlier than females. Monthly gonadosomatic index values showed that the peak spawning period for chubs was between April and June. The fecundity (F) - length relationship of S. anatolicus was LogF = -0.44697 + 3.33868 * LogL (R² = 0.7168). The mean egg diameter of S. anatolicus was 0.93 mm and the average fecundity was 78408.
