Abstract
Praćene su promjene fizikalno-kemijskih svojstava vode i sastav fitoplanktona jezera Jošava prije i nakon proljetnog poribljavanja konzumnim šaranom (Cyprinus carpio) u 2018. godini. Porast koncentracije kisika u vodi, pH i sadržaj klorofila nakon poribljavanja upućuju na porast primarne produkcije u jezeru. Najveću zastupljenost u kvalitativnom sastavu fitoplanktona imale su vrste skupina Chlorophyta i Chrysophyta, a relativnom brojnošću su se isticale vrste razreda Chrysophyceae i Bacillariophyceae kojima pogoduju niže temperature vode u proljetnom razdoblju. U usporedbi s prethodnim istraživanjima, povećane koncentracije nutrijenata, posebice ukupnog fosfora te visoki sadržaj klorofila u vodi, ukazuju na povećanu eutrofikaciju, koja je naglašena u plićim dijelovima jezera gdje je izraženiji utjecaj prometa te stočarske i poljoprivredne proizvodnje.
Abstract (english)
The influence of spring stocking with common carp (Cyprinus carpio) on physico-chemical water properties and phytoplankton composition in Lake Jošava was conducted in 2018. The increase in oxygen concentration, pH and chlorophyll content after stocking indicate increased primary production in the lake. Members of the Chlorophyta and Chrysophyta predominated in phytoplankton qualitative composition, while Chrysophyceae and Bacillariophyceae adapted to lower spring water temperatures had the highest relative abundance. Compared to previous investigations, higher nutrient concentrations, especially phosphorus, as well as high chlorophyll content indicate the increased lake eutrophication, which is more pronounced within the shallower lake parts due to the stronger influence of traffic, livestock breeding and farming.
