Estimating length-weight, length-length relationships, and condition factor of eight fish species, a case study of Bashar River, Tigris drainage (Iran)
Abstract
This study investigate investigated the length-weight, length-length relationships and condition factor of eight fish species collected from Bashar River, Tigris drainage by sampling 341 specimens of Alburnus sellal (Heckel, 1843), Barbus karunensis (Khaefi, Esmaeili, Geiger & Eagderi, 2017), Capoeta aculeate (Valenciennes, 1844), Capoeta coadi (Alwan, Zareian & Esmaeili, 2016), Chondrostoma regium (Heckel, 1843), Garra gymnothorax (Berg, 1949), Glyptothorax galaxias (Mousavi-Sabet, Eagderi, Vatandoust & Freyhof, 2021) and Turcinoemacheilus hafezi (Golzarianpour, Abdoli, Patimar & Freyhof, 2013). The results showed that the b parameter was form 2.41 (in C. aculeate) to 3.88 (in A. sellal) and condition factors ranged from 0.74 (in A. sellal and B. karunensis) to 1.35 (in C. aculeate). The coefficient of determination (r2) in the length-weight and length-length relationships was > 0.83. In conclusion, allometric growth patterns for A. sellal, B. karunensis, G. gymnothorax, and G. galaxias were positive while for C. aculata, C. regium and T. hafezi, and C. coadi presented negative patterns. This study represents the first data for G. galaxias.
