Abstract :This study presents a comprehensive view of the body condition and meat yield of Dreissena polymorpha in Çıldır Lake, Keban, and Karakaya reservoirs. A diverse sample of 472 D. polymorpha (154 from Çıldır Lake, 169 from Karakaya Reservoir, and 149 from Keban Reservoir) was collected. The condition index of zebra mussels in the Keban reservoir was the highest, with an average of 46,88, followed by zebra mussels in the Karakaya reservoir with 46,33. The zebra mussel in Çıldır Lake showed the lowest value, averaging 20,77. The fresh meat yield of zebra mussels in Çıldır Lake was lower than the fresh meat yields of zebra mussels in the Keban and Karakaya reservoirs. However, dry meat yield was higher. The dry meat yields of zebra mussels in all three reservoirs were found to vary significantly (P<0.05).
