Socio-ecological implications of black spot disease in European perch: linking parasite dynamics and angler behaviour in a large shallow lakehttps://hdl.handle.net/21.15109/ARP/UMUIYTPallos, RékaBánó, BálintTakács, PéterARP2026-03-252026-04-07T13:16:17ZThis dataset contains photographic data used to study parasitism in European perch (Perca fluviatilis) from Lake Balaton. We analyzed photographs to determine the location of parasites on the perch’s body, investigating both the prevalence and also the spatial distribution of Apophallus donicus in Lake Balaton. Additionally, we created a Hungarian questionnaire targeting the national perch-angling community (through social-media groups and fishing associations), though anyone with the link could participate.Earth and Environmental Sciencesfishperchparasitecitizen sciencetrematodeLake Balaton2026-03-25Pallos, Réka2026-03-25CC BY-NC 4.0
