As many ecosystem services (e.g., habitats for protected wildlife, nutrient cycling, etc.) are correlated with the proportion of reed beds relative to open-water areas, it is important in environmental studies to be able to accurately estimate the extent and the temporal dynamics of reed cover. Here, we propose a method for mapping reed cover in fish ponds from freely available Sentinel-2 imagery using the normalized difference vegetation index (NDVI), which we applied to Hungary, the third largest carp producer in the EU. The dynamics of reed cover in Hungarian fish ponds mapped using satellite imagery show a high degree of agreement with the ground-truth points, and when compared with data reported in the annual aquaculture reports for Hungary, it was found that the calculation of reed cover based on the NDVI-based approach was more consistent than the estimates provided in the report. We discuss possible applications of this remote sensing technique in estimating reed-like vegetation cover in fish ponds and the possible use of the results for climate change studies and ecosystem services assessment.}, year = {2023}, eissn = {2073-4441}, orcid-numbers = {Kerezsi, György/0000-0002-6912-615X; Gyalog, Gergő/0000-0002-3778-203X} } @article{MTMT:3388966, title = {Multifunctionality of pond fish farms in the opinion of the farm managers: the case of Hungary}, url = {https://m2.mtmt.hu/api/publication/3388966}, author = {Popp, József and Békefi, Emese and Duleba, Szabolcs and Oláh, Judit}, doi = {10.1111/raq.12260}, journal-iso = {REV AQUACULT}, journal = {REVIEWS IN AQUACULTURE}, volume = {11}, unique-id = {3388966}, issn = {1753-5123}, year = {2019}, eissn = {1753-5131}, pages = {830-847}, orcid-numbers = {Popp, József/0000-0003-0848-4591; Duleba, Szabolcs/0000-0002-2367-752X; Oláh, Judit/0000-0003-2247-1711} } @inbook{MTMT:1395911, title = {Carp Farming in Central and Eastern Europe and a Case Study in Multifunctional Aquaculture}, url = {https://m2.mtmt.hu/api/publication/1395911}, author = {Szűcs, István and Stündl, László and L, Váradi}, booktitle = {Species and system selection for sustainable aquaculture}, doi = {10.1002/9780470277867.ch26}, unique-id = {1395911}, year = {2007}, pages = {389-415}, orcid-numbers = {Szűcs, István/0000-0001-8041-6636} }
