“…In the present study, the values found for C. angorae showed negative allometry in the growth of both sexes. The results received were compared with previous LWRs studies in Anatolian watersheds (Alp et al, 2005;Emre et al, 2014;Ayyıldız et al, 2015;Erguden, 2016), Table 2. The values of b for the Asi River were close to the data marked from Alp et al (2005), Emre et al (2014) and Ayyıldız et al (2015) for the reservoir and river system of Turkey.…”

“…Capoeta angorae (Hankó, 1925) is the commercially valued and Anatolian endemic fish in the Asi River Basin and distributed along the river. In recent studies, C. angore have been reported in the inland waters of Turkey (Başıaçık, 2013;Emre et al, 2014;Ayyıldız et al, 2015;Erguden, 2016).…”

The length-weight relationship (LWR) for commecially important Ankara barb, Capoeta angorae was studied. A total of 208 specimens, collected from Asi River during the period from March 2015 to February 2016 were examined. The relationship between length and weight of the samples were evaluated as W = 0.020xL 2.784 (R 2 =0.983). Negative allometric growth for all individuals was found. Fulton's condition (CF) factor values showed significant variations (P<0.001) for both females (1.102) and males (1.068). To the best knowledge of this study presented the first reference on LWR and Condition Factor (CF) this species from Asi River.

“…By applying a relationship between the otolith morphology and fish length, it is possible to predict the fish size (Echeverria, 1987;Gamboa, 1991). Recently, researchers have shown an increased interest in the use of otoliths for calculating the fish sizes Ayyildiz, Emre, Ozen & Yagci, 2014;Ayyildiz, Ozen & Altin, 2014a;Ayyildiz, Ozen & Altin, 2014b;Ayyildiz, Ozen & Altin, 2015;Echeverria, 1987;Emre et al, 2016;Emre, Ayyildiz, Ozen & Yağcı, 2014;Kumar, Nikki, Oxona, Hashim & Sudhakar, 2017;Templeman & Squires, 1956). Otoliths may also assist to identify fossil fish species for paleontological studies (Nolf, 1995).…”

“…Asteriscus otoliths are the most preferred otoliths because they are the largest of the three pairs of otoliths in bony fishes which members of the Cypriniformes (Hecht, 1977). The age and growth of these species have been studied from Menzelet Reservoir (Ayyildiz, Emre, Ozen & Yagci, 2014), Fırnız Stream (Emre, Ayyildiz, Ozen & Yağcı, 2014) and a small river entering the Eğirdir Lake (Emre et al, 2016) by using asteriscus otoliths.…”

The relationships between asteriscus otolith morphology (OL, OW, OR and OM) and fish total length were described with a non-linear function (power model) for seven Cyprinid fish species: Capoeta angorae, C. antalyensis, C. caelestis, C. erhani, C. pestai, Pseudophoxinus antalyae and P. fahrettini. These species are endemic to Turkey and have limited distributions. The regression models are quite well fitted with all asteriscus otolith measurements. We were also conducted the regression models for genus level. There was no significant difference between the size of the left and right otoliths (paired t-test) in any of the seven species. This is the first study that examines the relationships between asteriscus otolith morphology and fish total length for four Cyprinid species. These results showed that the equations generated to obtain the fish size using otolith morphology data can be used in dietary studies.

The Length-weight relationships (LWRs) are very important to data for accurate estimate of populations in stock menagement. In this study, the length-weight relationships of some fish in Göynük stream, Murat River (Bingöl/Turkey) were examined. The LWRs and condition factor (K) of Cyprinon macrostomus, Gara rufa, Barbus lacerta, and Acanthobrama marmid were analyzed. LWRs was estimated using the linear regression model. LWRs were obtained as TW = 0.013L2.98, 0.057L2.40, 0.016L2.79 and 0.029L2.82 for C. macrostomus, G. rufa, B. lacerta and A.marmid, respectively. The b values acquired in the four fish species ranged from 2.13 (G. rufa-Male) to 3.34 (B. lacerta-Male). The K of the fish species varied from 0.90 (A. marmid-Male) to 1.27 (G. rufa-All), indicating that most of the fish were in good condition. However, C. macrostomus and G. rufa were better condition than B. lacerta and A. marmid. The study has provided baseline information on the LWR and K of the fish species in Göynük Stream. The datas that would be useful to adapt the adequate regulations for sustainable fish stock estimation in the stream for fishery biologist.
