The PhD Thesis enütled "Heavy metal immunotoxicology ard skin mucr¡s in fish'" is presented by Mr. Francisco Guardiola Abellan and focusm on the main immunophysiological effects due to the e,nposureof Sparus aurata to heavy metals and the role exertedby skin layer in terms of defencemechanisms. Particularly, in the first secfion of the PhD Thesis, a detailed invesügation was shown screeningthe histopathologicalconsequences on fish health of the exposureto arsenic, cadmium and mercury which were appropriately selected as target metals due to the potential risk of contaminaüonof water for aquaculture. In the second section of the PhD Thesis, a deep researchwas conducted conceming the barrier of skin mucus ard its interactionswith pathogenswhich can attack fish healft. At the beginning, the characterizafron of the physico-chemicalproperties of the skin was described and, then, the comparisonof the skin defencein severalmodel fishes allowed an interesting interpretation of the mecharisms involved in such defence. The two sections are well connectedeach other in a rational architectureof the work. Overall, the topic of Mr. FranciscoGua¡diola Abellan's PhD Thesisis very appealingfor its involvement in the scenario of aquaculfure and, for this purpose" several advanced techniquesbelonging to immunology and physiology field have been exploited to elucidate the behavior of cell fish. In addition, Mr. Francisco Guardiola Abellan's chemical background is also well docurnented by the studies performed in his PhD Thesis, so revealing a multidisciplinary perspecüveof the scienüñc issues and the Mr. Francisco GuardiolaAbellan's ability to managewith different methodologieswhich is crucial for the interpretation of biological phenomenaAt this regard, during his PhD Thesis, Mr. Francisco Guardiola Abellan's educafionhas included the researchvisiting stay abroadon behalf as ErasmusPlacement Fellow at Dipartimento di Scieraee Via Orabona4 - CampusUniversitario - 701?5 Bari (ltaly) Tel (+391ABA 544 2114 adriana.trapani@unibait Fax{+39) 080 544 2050 cF 80002170724- P tVA 01086760723 UNIVERSITA dinartimentodi DEGTISTUDT DI BARI frimacia-scienzedel frnnam ALDO MORO Tecnologie Biologiche Chimiche e Farmaceutiche af University of Palermo (Italy) and the pa*icipation at severalnational and international Conferences.Altogether, such experiences have contributd not only to highlight the topic of the PhD Theis, but also to cultivate good skills for the presentationand üscussionof the resultingdata Notably, all tfre extensive research work performed during Mr. Francisco Guardiola Abellan's PhD Thesis allowed the publication of 15 articles on peer reviewedjoumals, I chapterof book and 4 manuscriptscurrently under review.

It also presentssubstantial elements of originality; in fact Dr. Guardiolahas madea fimdamsntalcontribution to scientific researchin the field of the immunesystem of teleostfish, facing the argue in an innovativekey. The thesisis innovativein relationto the topics,referring in complete and thoroughmanner to the trend of internationalresearch on the subjectcited above. This hasallowed to developthe scientificapproach from a theoreticalphase to a phase application.The l,rnowledge of the immunesystem of fislr, in general,and of the species of interestin aquaculture,in paticular, has becomeone of the primary objectivesin resea¡chapplied to aquaculture.The PhD thesis is distinguished,in fact, for the ability to combinetheoretical and experimental analysis of a proposalphase and realization of the resultsachieved. The research findings are interesting and analyzed with a strongcritical sensewhich allowsto identify issuesthat may be the subjectof subsequentscie,ntific insights.Excellent narative skills inherentin the doctoralthesis that throughcareful selectionof contentand graphicalform tums out to be al¡eadyin this first draft of an excellentreference for ex¡ertsand technicians in the field of scie,ntificreference.
