Abstract :
To the study of biological and biosystematic characteristics of Capoeta fusca Nikolskii, 1897 in Southern Khorasan province, 225 specimen were collected by Fish nets (with openings of 1 mm) of three location in Lut drainage basin and seven location in Bejestan drainage basin. In the survey were study 11 morphometric character and 6 meristic character of this species. The study of relationship between Total length- Head length, Total length- Body Depth and Head length-Body Depth factors showed they have a positive and significant correlation and have./99 of correlation coefficient and the study Length-weight relationship in this species showed these factors have the growth negatively allometric. Also calculation of the Relative length of glutindex(RLG) and Vacuity index(VI) showed this species is an herbivorous fishand relatively gluttonous.
