“…From the reports of Kara & Solak, (2004), the chub population of Sır dam lake has a better growth performance than the Beysehir dace population in the Oymapınar Dam Lake. The average weight values reported on Topçam dam lake (Şaşı & Balık, 2003), Işıklı lake (Balık et al, 2004), Yeniçağal lake (Kılıç, 2011) and Keban dam lake (Aydın et al, 2015), are lower than the average weights recorded in this study. According to Kırankaya & Ekmekçi, (2007), besides climatic and geographical differences, the fact that the dam lakes are in different ontogenic stages, and the natural lakes and artificial lakes undergo different ontogenic developmental processes might contribute to the different growth rates in the populations of different water bodies.…”

This study aimed to determine some biological parameters such as age, growth condition factor, length-weight relationship, and sex ratio of Beysehir daces (Squalius anatolicus) sampled from Oymapınar dam lake between March 2016 and February 2017. A total of 422 Beysehir daces were sampled using 100 m long and 2,5 m depth monofilament gillnets (20, 30, 40, 50 mm mesh size) from the Oymapınar dam lake. The ages of the Beysehir daces ranged between II and VIII. The oldest age for females was VIII and VII for males. The sex composition of the sampled fish showed that 47.39 % of the samples were females and 52.61% were males. It was determined that the fork lengths of the females varied between 20.0 cm and 55.1 cm and the weights varied between 93.37 g and 2307.88 g. Von Bertalanffy growth parameters for all individuals were determined as L∞ = 60.57 cm, W∞ = 3260.79 g, k = 0.160 and t0 = -0.877 The b values of the length-weight relationship for females, males and all individuals were 3.202, 3.185 and 3.194, respectively. The average condition factor (CF) for all individuals was calculated as 1.278 ± 0.006. The findings of this study will aid in the development and implementation of longterm management plans for the Beysehir dams in this lake, as well as serve as the foundation for future research on the biological parameters of fish living in this lake.

“…Balık et al, (2004) also reported a lower female to male ratio 40.72% for females and 59.28% for males in Işıklı Lake, Turkey. But the findings of this study disagree with the report of 72.89% for females and 27.1 l% for males, giving a female to male ratio of 2.69:1.00 in Topçam Dam Lake, Turkey (Şaşı & Balık, 2003), 55.06% for females and 44.95% for males in Sır Dam Lake, Turkey by Kara & Solak, (2004), 59.80 % female and 40.20 % male in Keban Dam Lake, Turkey by Aydın et al, (2015). The proportion of the various age groups in a population gives an important idea about the reproductive power of the population and the future status of the population (Nikolsky, 1963;King, 2007).…”

This study was conducted in Oymapınar Dam Lake from March 2016 to February 2017. The study investigated the age composition, spawning season, sex ratio, age and length at first sexual maturity, and fecundity of Beysehir dace (S. anatolicus). The ages of the 422 Beysehir daces sampled from Oymapınar Dam Lake ranged from II to VIII of which 200 (47.39%) were females and 222 (52.61%) were males. The fork lengths and weights of female Beysehir daces varied between 20.0 cm and 55.1 cm and 93.37 g and 2307.88 g respectively. The oldest age group was VIII for females and VII for males. The length at first sexual maturity for females and males were 26.0 cm and 23.0 cm, respectively and the age at first sexual maturity for females and males were III and II, respectively. This shows that males mature earlier than females. Monthly gonadosomatic index values showed that the peak spawning period for Beysehir daces was between April and June. The fecundity (F) -length relationship of S. anatolicus was LogF = -0.44697 + 3.33868 * LogL (R² = 0.7168). The mean egg diameter of S. anatolicus was 0.93 mm and the average fecundity was 78408.

“…Otolitlerle ile ilgili son yıllarda birçok çalışma yapılmıştır. Bu konu ile ilgili; Akdeniz de yaşayan yalancı ısparoz, dil balığı ve kurbağa balıklarının otolit boyu-balık boyu arasındaki ilişkileri [3, 4 ve 5], dil balığının otolit boyutları-balık boyu ilişkileri [6], Kırmızı mercan balıklarında otolit-balık ilişkileri [7], kalkan balığının balık uzunluğu-otolit uzunluğu [8] yapılan çalışmalardan Squalis türleri ile ilgili birçok çalışma mevcut olup Işıklı Gölü, Keban Baraj Gölü, Borçka Baraj Gölü, Uzunçayır Baraj Gölü ve Almus Baraj Gölü'nde yaşayan Tatlısu kefalinin bazı büyüme karakterlerini incelemişlerse de [9,10,11,12 ve 13] Squalis semae türü için yapılan herhangi bir çalışmaya rastlanılmamıştır. Bu anlamda çalışmanın verileri yapılacak olan yeni çalışmalara kaynak teşkil edecektir.…”

MURAT NEHRİ'NDE YAŞAYAN Squalis semae' nin OTOLİT BOYUTLARI-BALIK BOYU ARASINDAKİ İLİŞKİLER ÖZ Bu çalışmada Murat Nehri'nde yaşayan tatlısu kefalinin otolit biyometrisi-balık boyu arasındaki ilişki incelenmiştir. Toplam 46 tane tatlısu kefalinin boy ve ağırlıkları ölçülmüştür. Balıkların minimum ve maksimum toplam boyları ve ağırlıkları sırasıyla 17.5-34.50cm ve 61.3g ve 537.9g olarak ölçülmüştür. Balıkların sağ ve sol otolitleri çıkarılıp ağırlıkları, genişlikleri ve boyları ölçülmüştür. Tüm balıkların sağ ve sol otolit ağırlıkları 0.0076-0.0235g, sağ ve sol otolit genişlikleri 1.454-2.264mm, sağ ve sol otolit boyları 1.793-2.925mm arasında bulunmuştur. Tatlısu kefalinin sağ ve solundan alınan otolitlerin genişlikleri, boyları ve ağırlıkları arasındaki fark istatistiksel olarak önemsiz bulunmuştur (P>0.05).
