- Abstract
Abstract??Sharpsnout bream (Diplodus puntazzo) has been used in Adriatic aquaculture for less than a decade, but the decreasing trend of rearing this species will probably result in its complete substitution by more exploited sea bream (Sparus aurata). Only two facilities still rear both fish species in neighbouring cages in monoculture. A switch of parasites was observed between sparids during monitoring of the gill monogeneans of farmed fish. In wild fish of the Adriatic Sea,Lamellodiscus elegans(Monogenea: Monopisthocotylea) has previously been reported in annular (Diplodus annularis), and two-banded sea bream (D. vulgaris) and sharpsnout bream (D. puntazzo), and the present study confirmed its presence also in sea bream, in low prevalence and abundance. The exclusively sea bream monogeneanSparicotyle chrysophrii(Monogenea: Polyopisthocotylea) was also isolated from sharpsnout bream, showing prevalence and abundance values even higher than in its resident host. In the occurrence ofL. elegansin sea bream, the opportunistic switch resulted in lower abundance and prevalence than in the original host, while in the second case of switching the monogeneanS. chrysophriishowed better reproductive capacity on a new host (sharpsnout bream). Both cases point to the possible enlargement of parasite host range.
