DISTRIBUTION NAD MORPHOMETRIC CHARACTERISTICS OF MUDMINNOW, Umbra krameri, WALBAUM, 1792

Crnka je jedina reliktna vrsta iz roda Umbra prisutna u Europi, endemična za bazene Dunava i Dnjestra. Zbog mjera isušivanja njezinog staništa i pretvorbe u obradive površine, te regulacijom rijeka, populacija crnke značajno su smanjene. Iz navedenih razloga, ova vrsta se nalazi na IUCN Crvenoj listi i ima status ranjive vrste. Istraživanje je provedeno u Požeškoj – slavonskoj županiji u blizini naselja Vaška na ribolovnoj vodi Mlinski kanal. Za potrebe ulova ribe crnke, zatraženo je i odobreno rješenje Ministarstva poljoprivrede, Uprava ribarstva. Ribolov je obavljen korištenjem elektroribolovnog agregata. Tijekom uzorkovanja iz Mlinskog kanala je izlovljeno 10 primjeraka riba crnki. Laboratorijski rad obavljen je prema knjizi Fisheries techniques, ur. Murrphy i Willis (1996) u laboratoriju Zavoda za lovstvo, ribarstvo i pčelarstvo.The mudminnow is the only relict species of the genus Umbra present in Europe, endemic to the basin of the Danube and Dniester. Due to the measures draining its habitat and conversion into arable land, and regulation of rivers, mudminnow populations were significantly reduced. For these reasons, this species is on the IUCN Red List and has the status of vulnerable species. The study was conducted in Pozeska - Slavonia County near the village Vaška on fishing water Mlinski Channel. For the purpose of catching, we requested permission and it was granted by the Ministry of Agriculture, Fisheries Directorate. Fishing is done using lectrofisher. During sampling from Mlinski Channel 10 specimens of mudminnow was caught. Laboratory work was performed according to the book Fisheries techniques, ed. Murrphy and Willis (1996) in the Department of wildlife, fishery and beekeeping laboratory
