One such parasite is <i>Sparicotyle chrysophrii</i> (Platyhelminthes: Monogenea), which commonly infects cultured gilthead seabream (<i>Sparus aurata</i>)-a vital species in Mediterranean aquaculture. The parasite attaches to fish gills and can cause epizootics in sea cages with relevant consequences for fish health and associated economic losses for fish farmers. In this study, a novel stratified compartmental epidemiological model of <i>S. chrysophrii</i> transmission was developed and analysed. The model accounts for the temporal progression of the number of juvenile and adult parasites attached to each fish, as well as the abundance of eggs and oncomirRoyal Society open scienceA stratified compartmental model for the transmission of <i>Sparicotyle chrysophrii</i> (Platyhelminthes: Monogenea) in gilthead seabream (<i>Sparus aurata</i>) fish farms^†.PMC10189595862658Stella EKolega MMusmanno APasetto DColak SMari LGustinelli APastres RMejdandzic DBertuzzo EfalseA stratified compartmental model for the transmission of <i>Sparicotyle chrysophrii</i> (Platyhelminthes: Monogenea) in gilthead seabream (<i>Sparus aurata</i>) fish farms^†.The rapid development of intensive fish farming has been associated with the spreading of infectious diseases, pathogens and parasites.
