dc.description.abstractAge, growth and reproduction of the Shemaya, Chalcalburnus chalcoides, was studied in the Ömerli Reservoir, a large drinking water system located in Istanbul province (Turkey). The von Bertalanffy growth function displayed variation in growth rates between the sexes. Asymptotic lengths calculated for both sexes were high, probably due to the lack of large predatory fishes and lack of fishing in the reservoir. Females dominated all age classes with the exception of the second age, and this phenomenon is characteristic of species from unstable and variable environments. The condition factor and the gonadosomatic index indicated that reproduction occurred around May-June. The estimated mean lengths at first maturity (LT50) were 14.83 cm and 15.98 cm for males and females, which corresponded to 1 and 2 years of age for both sexes. Natural mortality was 0.47/year. Fishing mortality as well as exploitation rate was negligible since fishing activity is prohibited throughout the year. © 2005 Taylor & Francis Group, LLC.
