Carassisus gibelio, gynogenetic, invasive, erythrocyte nucleus area


Carassius gibelio originated in Central Asia and is an invasive species all over Europe and our country. C. gibelio gives significant damages to natural ichthyofauna and water quality in inland waters it enters. From Turkey, this species was reported first in 1988. Today, it has invaded many wetlands. The main reason for its success in invasion is gynogenetic reproductive ability. This species forms triploid individuals with 3n chromosomes using sperm from other Cyprinidae. There are three basic methods for determining the triploid population. These include determining the number of chromosomes, calculating the area of erythrocyte nuclei, and determining the amount of DNA by flow cytometry. In this study, smear preparations were made from blood samples of the ten C. gibelio samples caught from the Ula Pond. For each individual, erythrocyte nucleus area of at least 100 cells was calculated and arithmetic average calculated, and the gynogenetic reproduction potentials were investigated. The erythrocyte nucleus area of triploid (3n=156-164) individuals formed by gynogenetic reproduction is at least 1.31 percent larger than diploid (2n=100) individuals. Of the blood samples taken from individuals, the smallest of the erythrocyte nucleus area was found to be 10,89 µm2 and the largest was 19.30 µm2. According to these results it has been found to have gynogenetic reproductive potential.
