Length-weight relationship and condition factor of ten fish species (Cyprinidae, Sisoridae, Mugilidae, Cichlidae, Gobiidae and Channidae) from Iranian inland waters
Keywords:Length- weight relationship, Iranocichla persa, Romanogobio persus
During 2010-2017, a total 296 specimens including Romanogobio persus, Hemiculter leucisculus, Schizothorax pelzami, Rhodeus amarus and Cabdio morar (Cyprinidae), Glyptothorax silviae (Sisoridae), Planiliza abu (Mugilidae), Iranocichla persa (Cichlidae), Glossogobius giuris (Gobiidae) and Channa gachua (Channidae) were collected using electrofishing device with ranging from 3.3 to 14.95 cm (in total length) and 0.85 to 36.57 g (in total weight). Based on the results, the growth coefficient values “b” ranged 2.75 (R. amarus) to 3.62 (C. morar). R2 in length-weight relationships estimated were greater than 0.851. Also condition factor of the studied fishes was ranged from 0.6 (R. persus) to 1.47 (R. amarus). This study represents the first reports of LWRs data for G. giuris, I. persa and R. persus from Iranian inland waters and this reported for R. persus and I. persa are first in fish base. The results of this study provides useful information for further fisheries management, fish population dynamic studies and for comparisons in future studies.
