Abstract

The purpose of this study was to examine the status of ginogetic population Uluabat Lake Carassius gibelio. In this study, 466 individuals were caught per month between March 2006 and February 2007. It has been determined that 65% of the obtained samples are comprised of females, 34% is comprised of males and 1% is comprised of individuals, which are not mature sexually. Chromosome photographs were shoot by preparing chromosome preparations from the gills of 5 female individuals caught in the lake and in the chromosome remuneration based on these photographs it has been observed that 4 individuals has 2n = 100 chromosomes whereas one individual has 3n = 156 chromosomes. This result indicates that the C. gibelio population in Uluabat Lake is comprised of different colonies including diploid and triploid individuals.
