Abstract

Istraživanje zooplanktona i fizikalno-kemijskih parametara u Visovačkom jezeru provedeno je tijekom srpnja i listopada 2012. te svibnja 2013. U 2013. godini provedeno je još jedno uzorkovanje tijekom listopada. Najveća rasprostranjenost i intenzitet hipoksično-anoksičnih uvjeta zabilježeni su u srpnju 2012., a razlog tomu je pojačana primarna produkcija. Analizom planktona utvrđeno je da ukupna brojnost makrozooplanktona ovisi o vremenskom razdoblju i dubini vodenog stupca. Pronađeno je ukupno 7 vrsta planktonskih račića, četiri vrste iz skupine Cladocera (rašljoticalaca) te tri vrste iz skupine Copepoda (veslonožaca). Vrste iz skupine Copepoda su bile brojnije nego vrste iz skupine Cladocera u srpnju i listopadu 2012. godine, dok su Copepoda prevladavali u svibnju i listopadu 2013. godine. Harpacticoida su zabilježeni samo povremeno s malim brojem jedinki. Tijekom istraživanog razdoblja na svim postajama dominirale su vrste koje pripadaju trofičkoj kategoriji makrofiltratori.

Abstract (english)

Research on zooplankton and physical-chemical parameter analysis of the Visovac Lake was conducted in July and October in 2012, and during May 2013. In 2013 was conducted another sampling during October. Hipoxic/anoxic conditions were noticed in July 2012, due to increased primary production. Macrozooplankton abundance varied seasonally and was also dependent of depth. Seven species of freshwater Crustaceans were found: 4 Cladocera and 3 Copepoda. Copepods outnumbered cladocerans in July and October 2012; cladocerans dominated in May and October 2013. Harpacticoids were determined only occasionally. Macrofiltrators dominated upon all other trophic categories during the whole investigation.
