Sažetak: The freshwater ichthyofauna of Adriatic basin is characterized by a large number of endemic species, which are distributed on a restricted area. The makal dace (Squalius microlepis) is an endemic species living only in the Neretva River basin and mainly in the sinkhole river Matica in Bosnia and Herzegovina (BiH) and Croatia, Prološko Lake and accumulation of Ričica near Imotski in Croatia. Population structure was studied on 51 individuals caught by gill nets at location on the Matica River near Drinovci in BiH. The aim of this study was to determine the population structure of makal dace, according to length and weight, and length-weight ratio between total length (cm) and weight (g). The results are presented in the form of frequency histograms, linear and weight structure, and length-weight ratio between total length (TL) and weight (W). Individuals with total body length of 19-20 cm are dominating, with maximum total length of 28 cm. The maximum recorded weight was 269.30 g. The frequency histogram of body weight show that weight class 60-90 g dominates too. Positive allometric growth with high b-value of 3.47 has been determined. This research provided new results on structure of population of the endemic makal dace.
