Eponymy: Borivoj Knezevic (1948–1988) was a Yugoslav (Montenegrin) biologist who dedicated his life to the study and conservation of the freshwater fishes of Montenegro. He co-wrote: Utilization of filamentous algae by fishes in Skadar Lake, Yugoslavia (1978). (Ref. 128868), visit book page.

简单描述

Distinguished from other species of the genus by having shallow body, with depth from slightly more (in large specimens) to slightly less than head length, and usually 36-38 lateral line scales (range 35-39). Diagnosed further by the following combination of characters (none of them unique to the species): uniform silvery body coloration with a crescentic dark mark on each scale pocket, more or less evident in preserved specimens; 9 branched anal-fin rays; and 11-12 total gill rakers (Ref. 55977). Differs from its congeners in Balkan Peninsula by the combination of the following characters: 34-37 + 2-3 scales along lateral line; anal fin with 9½ branched rays; 10-12 gill rakers; back humped behind nape; articulation of lower jaw in front of anterior margin of eye; eye not close to dorsal head profile when viewed laterally; and all fins greyish (Ref. 59043).
有别于其他本属的种借着具有浅的身体, 随着深度从约略更 (在大的个体中) 对些微少于头长, 与通常 36-38个侧线鳞片 (范围 35-39). 鉴定了进一步藉由跟随组合 fo 特征:(他们没有一个此鱼种唯一的 ) 均匀的银色身体颜色在每个鳞囊上具有一个新月形的深色印记, 约略显著的在保存的标本中; 9个分枝的臀鳍棘条; 而且 11-12个总鳃耙.(参考文献 55977)
Occurs in lakes (Ref. 55977). Inhabits deep pools and canals in swampy areas along lake shores or in floodplain. Breeds in April-May. Attains a maximum size of about 26 cm SL (Ref. 59043).
