Abstract

In this study, length-weight relationships (LWRs) and length-length relationships (LLRs) for Rhodeus amarus sampled from the Terme and Terice Streams were calculated in April-November 2016. A total of 117 fish specimens (from Terme = 57, from Terice= 60) were examined. Total, fork and standard length were measured (±0.1 cm) and weighted (±0.01 g) for all captured fish. Total length varies between 4.5 and 8.9 cm, weight varies between 0.730-9.940 g for all populations. Length-weight equations were calculated as W=0.005TL3.479 and W=0.004TL3.586 for Terme and Terice, respectively. According to analyses bitterling has positive allometric growths for two localities. Length-length relationships equations show that total, fork and standard length values are very strong between each other (P<0.001, coefficient of determination >0.95).
