Abstract

In this study, length and weight data for three endemic fish species of North-western Anatolia (Capoeta baliki, Capoeta sieboldi and Chondrostoma angorense) were collected throughout their distribution ranges and used to estimate length-length, total length (TL) – weight and empirical standard weight (Ws) equations. The obtained Ws equations were: log10Ws = -6.743 + 4.768 log10 TL - 0.437 log10 TL2 (TL range: 7-28 cm) for C. baliki; log10Ws= - 5.966 + 3.833 log10TL - 0.181 log10 TL2 (TL range: 7-36 cm) for C. sieboldii; log10Ws= - 10.017 + 7.402 log10TL - 0.971 log10TL2 (TL-range: 7-24 cm) for C. angorense. For C. angorense, these data represents the first reference on length-weight for the species. In addition, a new maximum length was reported for C. baliki.
