  Çalışmada, sürdürülebilir avcılık stratejilerinin belirlenebilmesi amacıyla, Uzunçayır Baraj Gölü'ndeki Capoeta trutta'nın üreme özellikleri araştırılmıştır. Balık örnekleri 2013 yılının Ocak-Aralık ayları arasında farklı ağ göz açıklıklarına (36-100 mm) sahip sade uzatma ağlarıyla aylık olarak yakalanmıştır. Araştırma süresince Uzunçayır Baraj Gölü'nden yakalanan 385 adet C. trutta bireyinin 218 adedini (%57.00) erkek, 167 adedini (%43.00) ise dişi bireylerin oluşturduğu ve populasyonun I-XII yaş grupları arasında dağılım gösterdiği saptanmıştır. GSİ değerlerinin mayıs ayında maksimuma ulaştığı, sperm ve yumurtalarını mayıs-temmuz ayları arasında bıraktıkları tespit edilmiştir. Yumurta çapları 0.30-1.07 mm arasında değişmiştir. Fekondite-total boy ve fekondite-ağırlık arasındaki ilişkileri açıklayan denklemler sırasıyla; F= 29.708*TL593.36 (N= 35, r= 0.27), F= 9.6448*W+5488.3 (N= 35, r= 0.38) olarak hesaplanmıştır. C. trutta bireylerinin yaş gruplarına göre yumurta veriminin 1362-15428 arasında değiştiği belirlenmiştir. Eşeysel olgunluk boyu dişi bireylerde 20.77 cm, erkek bireylerde 19.35 cm olarak tespit edilmiştir

  In the study, on the purpose of contribute to sustainable fisheries strategies. the reproductive characteristics of Capoeta trutta in Uzuncayir Dam Lake were investigated. The fish samples were caught from Uzuncayir .Dam Lake by using gill nets with different mesh sizes (36-100 mm) between January - December 2013. During research period, a total of 385 C t mita samples that were caught from Uzuncayir Dam Lake yielded 167 female (43.00%) and 218 male (57.00%) with an age composition of population varied from I to XII age groups. GSI values reached a maximum in May and rapidly declined after that month, and it can be concluded that C trutta in Uzuncayir Dam Lake deposites its sperms and eggs between May-July. Egg size varied between 0.30-1.07 mm in dimeter. The relationships between fecundity-total length and fecundity-total weight were determined respectively as r= 29.708*TL-593.36 (N= 35. r= 0.27), F = 9.6148*W+5488.3 (N= 35. r= 0.38). The fecundity of C trutta individuals changed from 1362 to 15428 according to age groups. Sexual maturity length was determined as 20.77 cm and 19.35 cm for female and males. respectively.

  This study was conducted at Atatürk Dam Lake between April 2011-March 2012. In this study, a total of 231 (106 female, 125 male) Cyprinus carpio L., 1758 samples were analyzed. It was determined that samples were ranged between I-X age groups and male/female ratio was determined as 1.18:1 Total length values were ranged between 13.5-59.2 cm for males, 14.6-59.3 cm for females; weight values were ranged between 53.2-4662.5 g for males, 56.4-4668.0 g for females; condition factor values were ranged between 1.182-4.175 for males and 1.251-3.514 for females. Length-weight relationship for males W=0.0346*TL2.807(R2=0.95), female W=0.0246*TL2.8922 (R2=0.96) and in general population W=0.0295*TL2. 8472 (R2=0.95) were detected. VBBD (von Bertalanffy growth equation) for all population parameters L?=111.01, K=0.06, t=-1.48, W?=19746.57 and natural mortality (M) is determined as 0.1671. The highest average Gonadosomatic index values were determined in April for both sexes. Egg diameter values were measured between 0.60-1.33 mm, and the highest average value was found in April (1.27 mm). Reproduction period was determined between April-July. Fecundity values was calculated between 13468-885762. The first maturation was determined to be in age group III (30.848 cm in total length) for males and in age group IV (32.099 cm in total length) for females
