Alburnus alborella (De Filippi, 1844)(Actinoptery GII: Cyprinidae, Alburninae) in Buško Lake Ţujo Zekić D.1*; Riđanović S.1; Spasojević P.1 Received: May 2019 Accepted: December2019 Abstract In this paper we present data about first findings of species Alburnus arborella(Bonaparte, 1841) syn. Alburnus alborella (De Filippi, 1844) (Actinoptery GII: Cyprinidae, Alburninae) in Buško Lake (Municipality Livno).In this report twenty – four specimens were cought during research period in two seasons in 2018. More specifically, trips to the catchment areas were made in spring-summer season from 12.06.2018 to 18.07.2018. and 22.11.2018.Determination of individuals was made on the basis of analysis of individual morphometric and meristic characterswith the exact length and weight of the individuals.This is the first finding of this species probably brought and introduced by fishermen.The findings of this species in Bosnia and Herzegovina have so far been confirmed in the Neretva watercourse and in the Ričica river in the Republic of Croatia.
