Habekovic (1973, in Treer et al. 2003) summarized all introduced carps; it is evident that 97.5% were of fish-farm origin. The remainder were wild from the River Drava. Both groups come from north Croatia, part of the Danube basin distribution of carp. According to the contemporary data based on experience alone, the carp grew rapidly during the first years of introduction into the Vransko Lake, but growth decreased soon afterwards (Treer 1989, in Treer et al. 2003). In one survey the total length of females ranged from 35 to 62 cm and males from 34 to 66 cm; weight varied from 0.9 to 4 kg (females) and 0.7 to 4.5 kg (males) (Treer et al. 2003). Management Notes for this Location: This lake belongs to the Dalmatian division, the most specific of all the Euro-Mediterranean subregions because of its five endemic genera and many endemic species (Economidis and Banarescu 1991, in Treer et al. 2003). Prior to carp stocking, the most numerous fish in the lake were eel (Anguilla anguilla) and gray mullet (Mugil cephalus) (Morovic 1964, in Treer et al. 2003).
