The Population Structure And Growth Properties Of Chalcalburnusmossulensis (Heckel, 1843) Caught From Askale Region Of River Karasu, Mustafa Türkmen, İhsan Akyurt
Turkish Journal of Biology
In this study, the population structure and growth properties of Chalcalburnus mossulensis (Heckel, 1843) caught from Askale Region of River Karasu betwen February 1996 and January 1997 were examined. The age composition of population varied between I and VI ages, and the most abundant age group was the third age group (42.13%). The population was composed of 51.74% females and 48.26% males. The fork length and the body weights of males and females varied between 8.9-18.1 cm, 3.6-67.9 g and 8.5-18.5 cm, 5.1-79.5 g respectively. The specific and relative growth for length and weight were maximum in the second age. …

Karyotype analysis was performed in Chalcalburnus mossulensis (Heckel, 1843) belonging to the carp family by investigating the number and structures of their chromosomes. The fish used in this study were caught with fishing nets from Kizilirmak river and taken to the laboratory. They received an abdominal injection of 0.6 mg colchicine (Colchicum Dispert) dissolved in 1 ml of distilled water per 1 g body weight. As a result of the C-metaphase investigation, it was determined that C. mossulensis had 2n=48 chromosomes. Their karyotypes were determined to be composed of 6 metacentric, 10 submetacentric, and 8 acrocentric chromosome pairs. We were …
