Age and growth of Capoeta erhani (Actinopterygii: Cypriniformes: Cyprinidae) from the Menzelet Reservoir, Turkey

Length-weight relationships for six freshwater fish species from the Seyhan Reservoir (south-eastern Anatolia, Turkey)

“…The b value reported by Alp et al (2005) for C. angorae (2.681-2.807) from the Ceyhan River (Turkey) was not very close to our values when compared to the present study. Ayyıldız et al (2014) observed similar b values for C. erhani (3.000-3.201) from the Menzelet Reservoir (Turkey). Esmaeili and Ebrahimi (2006) reported almost similar b value results for G. rufa (3.139) for inland waters of Iran.…”

“…Ayyildiz et al (2014), studied age and growth of C. erhani in Menzelet Reservoir, Ceyhan River drainage and it was reported that growth of C. erhani is positive allometric for males (b = 3.2011), isometric for females (b = 3.0015) and allometric (b = 3.0892) for combined sex (Table 3). However, we observed isometric growth (b = 3.0996, n = 24) for combined sex of C. erhani.…”

“…The variation in the exponent (b) of the length weight Table 2. The parameters of the length-weight relationships of 9 species belonging to 4 different genus together with the regression coefficient (r 2 ), the number of specimens (n), minimum (min), maximum (max), mean ± standard error of the total length and 95% Confidence Interval b(±SE) of specimens measured and statistical results relationships of fish species could be affected by geographic locations, sampling area, seasons, sex, spawning time, sexual maturity, stomach fullness, size range and ecological factors such as temperature (Yılmaz and Polat, 2009;Erguden and Goksu, 2009;Ayyildiz et al, 2014). Different species belonging to the same genus can possibly affect the b value (Ayyildiz et al, 2014).…”

“…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).…”
