LENGTH-WEIGHT AND LENGTH-LENGTH RELATIONSHIPS OF RED-SPOTTED TROUT (Salmo trutta macrostigma (DUMERİL, 1858)) IN KARASU RIVER (EAST ANATOLIA, TURKEY)

Ebru İfakat ÖZCAN1 , Osman SERDAR2

In this study, the length-weight and length-length relationships were determined for Salmo trutta macrostigma (Dumeril, 1858) captured in the 15 different site of Karasu River (Tributary of Fırat River). A total of 104 specimens were catched by electroshocker, gill nets, and trammel nets between October 2014 to September 2015. The total length and weight of the sampled ranged between 8.6-27.4cm and 5.4-241g. The length-weight relationships were determined as W=0.0097L3.06 (R2=0.86) for females, W=0.0095L3.08 (R2=0.96) for males and W=0.0068L3.19 (R2=0.97) for all individuals. The types of growth for all individuals were positive allometric for Salmo trutta macrostigma. Length-length relationships were determined as TL=0.592+1.009FL, FL=-0.104+1.107SL and SL=-0.212+0.881TL for all individuals.
