Since none of the fish-based multimetric indices was developed to the marine environment, the present study had two main goals: to evaluate the efficacy of the existing indices and the development of an efficient multimetric index to promote the assessment of the ecological quality of the marine fish communities. Five estuarine indices were adapted to marine waters through the simple replacement of the functional estuarine groups for the marine ones and tested in fifteen zones of the Portuguese coast divided according to their substrate. Analysis of individual metrics suggests lack of representativeness and consideration for the particularities of each substrate's typical fish communities. These results strengthened the need of a new multimetric index development by type of substrate and depth. Recurring to a Drivers-Pressures-Impacts-Responses approach and previous studies, a set of metrics was selected and their redundancy was tested through multiple correlation matrices. Based on these results and ecological meaning of each metric, the Marine Fish Community Index (MFCI) was developed and divided in four typologies. Although, in the future, a good monitoring plan is need in order to solve some metric problems and to validate the reference values, the results of the MFCI application and it robustness test showed that this approach by typology is efficient to assess the ecological status. Therefore, a new index to assess the ecological status was successfully developed and can be applied on the evaluation of the quality of the marine environmentCabral, Henrique N.Costa, Maria José RosadoRepositório da Universidade de LisboaPires, Sofia Nunes Henriques Margarido2010-07-27T08:58:04Z20082008-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfapplication/pdftext/xmlhttp://hdl.handle.net/10451/1404enghttp://catalogo.ul.pt/F/?func=item-global&doc_library=ULB01&type=03&doc_number=000530874info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-11-08T15:40:54Zoai:repositorio.ul.pt:10451/1404Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T21:28:03.221570Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
