Abstract

Growth properties and length weight relationship are determined for endemic Aphanius marassantensis Pfleiderer, Geiger & Herder, 2014 in Hirfanli Reservoir. A total of 305 individuals are (115 females, 190 males) determined with a random method by using a gill nets (1.2 x 2 cm mesh sizes). Length weight relationship was W = 0.01075342 L-3.415 (R-2 = 0.881) for females, W = 0.01138892L(3.364) (R-2 = 0.904) for males. The Von Bertalanffy equations were L-t = 6.18 [1 - e(-0.191(t + 1.770))], W-t = 4.01 [1 - e(-0.191(t + 1.770))] for females, L-t = 7.07 [1 - e(-0.133 (t + 2.380))], W-t = 5.89[1 - e(-0.133 (t + 2.380))] for males. Aphanius is an endemic fish species and it shows its importance in terms of biodiversity. It is necessary to increase knowledge about endemic species and to monitor population trends and status.
