Abstract
The fish were sampled in the lower parts of the Bliznec stream using an electroaggregate on two separate occasions in November 2008. A total of 50 fish were sampled. The samples belonged to 4 distinct species: Carassius gibelio, Gobio gobio, Perca fluviatilis and Squalius cephalus. Chub was found to be the most abundant. All species apart from chub were found to exhibit negative allometric growth (b<3), yet all of them exibit a b value lower than the croatian average. CF was found to be very low and below croatian average for chub and perch, average for gudgeon, and slightly above average for prussian carp. The freshwater environment of Bliznec stream was found to be a species poor biotope.
