This study aimed to assess systemic and mucosal immune responses of Atlantic salmon (Salmo salar) exposed to two protein-hapten antigens dinitrophenol (DNP) and fluorescein isothiocyanate (FITC) each conjugated with keyhole limpet haemocyanin (KLH) administeredusingdifferentdeliverystrategies. Fishwereexposedtotheantigens through different routes, andwere givenabooster4weekspostinitial exposure.Bothsystemic and mucosal antibody responses were measured for a period of 12 weeks using an enzymelinkedimmunosorbentassay(ELISA).Onlyfishexposedtobothantigensviaintraperitoneal (IP) injection showed increased systemic antibody response starting 6 weeks post immunization. No treatment was able to produce a mucosal antibody response; however there was anincrease inantibody levels inthe tissue supernatantfromskinexplantsobtained12 weeks postimmunization from fish injected with FITC. Western blots probed with serum and culture supernatant from skin explants showed a specific response against the antigens.In conclusion,IP injection of hapten-antigen inAtlantic salmon was the best delivery route for inducing anantibodyresponse againstthese antigens inthis species.Eventhough IP injection did not induce an increase in antibody levels in the skin mucus, there was an increased systemic antibody response and an apparent increase of antibody production in mucosal tissues as demonstrated by the increased level of specific antibody levels in supernatants from the tissue explants.
