They are ecologically and economically important, have a wide geographical distribution and are harvested all over Europe. In Portugal, cockles are commonly found along all coastal areas and were the bivalve species with the highest landings in the country between 2010 and 2020. This importance emphasises the need for unravelling the origin of an individual using traceability techniques, when the harvesting location is doubtful, identifying and verifying illegal fishing activity or benefiting consumers through the detection of mislabelled seafood products. Distinguishing cockles’ populations based on morphological characteristics is difficult due to their morphological similarities, however, species and geographic identification studies often use morphological characteristics as tools to acquire most of this bivalve’s information. Geometric morphometrics is one of the most successful methods based on morphometry, providing a visual representation of shape change and producing shape variables that can be analysed through statistics. The aim of this work was to study the geographical variation of the shell shape of Cerastoderma spp. common in Portuguese aquatic systems such as Ria de Aveiro, the Tagus and Sado estuaries, the Albufeira and Óbidos lagoons, etc. The possibility of inferring the origin of an individual using shell morphology and multiple landmark-based geometric morphometrics methodologies was explored alongside the possibility of using such methods as traceability techniques. This work supports the use of landmark-based geometric morphometrics methods, being easy, low cost and effective in the study of shell shape variation. Using these methods allowed the discrimination of cockle populations from different aquatic systems on the Portuguese coast. Such methodologies could be extended to other bivalve populations and aquatic systems, becoming beneficial for the traceability of other populations and a valuable asset in fisheries in general.Chainho, PaulaRufino, Marta MRepositório da Universidade de LisboaMartins, Inês Rebolo2023-06-06T17:28:34Z202220222022-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10451/58015enginfo: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:RCAAP2023-11-08T17:06:47Zoai:repositorio.ul.pt:10451/58015Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T22:08:24.069273Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
