Sažetak
Microphytes are of great ecological importance and make up the majority of primary producers in aquatic environments. In ponds, their communities can be affected by fertilisation and supplemental feeding, a common management practise in fish farming that reduces pond water. The aim of the study was to investigate the epiphytic microphytes of common reed (Phragmites australis) in late autumn in four common carp (Cyprinus carpio Linnaeus, 1758) ponds in Donji Miholjac and Grudnjak. At each site, one pond with young-of- the-year and one pond with adult common carps were investigated. The ponds differed in physical and chemical parameters – water depth (0.80 - 2.45 m), dissolved oxygen concentration (3.75 - 12.88 mg/L), ammonium (0.11 - 0.89 mg/L), phosphates (0.15 - 0.78 mg/L), and chlorophyll-a concentration (7.81 to 53.09 µg/L). Water temperature was in accordance with seasonal conditions and similar in all ponds (8.7 - 9.0 °C). Epiphytic communities were diverse (> 100 taxa) and included most taxa from the Bacillariophyceae and Chlorophyta groups in all ponds. Further studies should focus on changes in epiphytic community composition and abundance as a function of season and supplemental feeding applied.
