Fig. 1.

Historical and recent distribution of the sichel in Slovenia and Croatia.

Fig. 2.

Measured morphometric traits (1) total body length; (2) standard body length; (3) head length; (4) head height; (5) preorbital distance; (6) eye diameter; (7) postorbital distance; (8) predorsal distance; (9) preanal distance; (10) maximum body height; (11) caudal peduncle length; (12) minimum body height, (13) length of base D; (14) length of base A; (15) length P; (16) length V, height of dorsal fin (17), height of anal fin (18), distance P-V(19), distance V-A (20). Abbreviations and schematic illustration were used according to Brylinska (1986).
