Abstract

Gölbaşı Gölü’nde (Hatay) bulunan Unio terminalis’in erkek ve dişi bireylerinde, besililik göstergesi olan kondisyon faktörü, bir yıl süresince boy gruplarına göre belirlenmeye çalışılmıştır. Başlangıç ayı Ekim olmak üzere 12 ay boyunca Gölbaşı Gölünden temin edilen U. terminalis’in erkek ve dişi bireylerinde uzunluk, genişlik ve yükseklik değerlerine bağlı olarak midye kabuk hacmi hesaplanmıştır. Midyelerin kabuktan ayrılmış yaş et ağılıkları erkek ve dişi bireyler için belirlenerek aylara ve boy gruplarına göre kondisyon faktörü tespit edilmiştir. Erkek ve dişi midyelerde boy gruplarına göre kondisyon faktörü karşılaştırıldığında, erkeklerin 4,50 - 4,99 cm boy grubunda 17,79 ± 1,46; dişi midyelerin 5,50 - 5,99 cm boy grubunda 19,76 ± 1,72 olduğu tespit edilmiştir. 12 aylık inceleme sürecinde kondisyon faktörünün erkek ve dişi midyelerde Ağustos ayında en yüksek, Ekim ayında ise en düşük düzeyde olduğu belirlenmiştir. Bu çalışma Gölbaşı Gölü’nde yaygın olarak bulunan U. terminalis’in kondisyon faktörü tespiti konusunda yapılmış ilk incelemedir.

Examination of condition factor in male and female of freshwater mussels (Unio terminalis) according to size groups.

Abstract

Condition factor, which is an indicator of fatness, in male and female individuals of Unio terminalis in Gölbaşı Lake (Hatay) was tried to be determined according to their height groups for one year. Mussel shell volume was calculated based on the length, width and height values of male and female U. terminalis obtained from Gölbaşı Lake for 12 months, starting from October. The wet meat weights of the mussels separated from the shell were determined for male and female individuals, and the condition factor was determined according to the months and length groups. Condition factors of male and female mussels were compared according to size groups. Condition factor was found to be 17.79 ± 1.46 in the 4.50 - 4.99 cm height group of men. It was determined that female mussels were 19.76 ± 1.72 in the 5.50 - 5.99 cm length group. It was determined that the condition factor in male and female mussels was highest in August and lowest in October during the 12-month examination period. This study is the first study to determine the condition factor of U. terminalis, which is common in Gölbaşı Lake.
