Secondary production of zooplankton, macrozoobenthos and fish stock assessment in the reservoir lake 'Zlatibor' on Zlatibor mountain

Abstract

During the 2001 (from spring to autumn), investigations of zoo- plankton and macrozoobenthos production, as well as fish stock assessment, were carried out in the reservoir lake "Zlatibor" on Zlatibor mountain. During the study period zooplankton biomass was in the range of 8.0581 to 25.9282 mg/1 and the average value 14.0876 mg/1. Bottom fauna biomass was in the range of 11.1154 to 17.4729 g/m2 with the average value 14.1368 g/m2. Quantity offish stock was estimated as 187.5 kg fish.

U toku 2001. godine (od proleća do jeseni) obavljena su istraživanja produkcije zooplanktona, makrozoobentosa, kao i procena ribljeg bogatstva u akumulaciji "Zlatibor" na Zlatiboru. Biomasa zooplanktona tokom obavljenih istraživanja se kretala od 8,0581 do 25.9282 mg/1 sa prosečnim vrednostima od 14,0876 mg/1. Biomasa faune dna je tokom istraživanja bila u dijapazonu od 11,1154 do 17,4729 g/m2, odnosno u prošeku 14,1368 g/m2. Procenom ribljeg bogatstva konstatovano je 187,5 kg riba po hektaru.
