Abstract(s)
Portugal, como um país com uma extensa costa, tem a responsabilidade de manter uma vigilância ativa sobre a área correspondente à sua jurisdição e soberania marítima. É essencial assegurar que todas as embarcações estejam de acordo com a legislação em vigor e que as autoridades responsáveis pela fiscalização disponham dos recursos necessários para conduzir atividades de controlo. Dada a crescente preocupação com a sustentabilidade do setor da pesca e a preservação das espécies, é necessário garantir que as embarcações respeitem as regulamentações de segurança e as cotas de pesca estabelecidas para proteger a biodiversidade. Este estudo baseia-se nas ações de fiscalização realizadas pela Marinha Portuguesa sobre embarcações de pesca comercial e nos dados do sistema Monitorização Contínua da Atividade da Pesca.
A análise abrange aspetos temporais e geoespaciais das atividades da fiscalização marítima, utilizando os dados que monitorizam a atividade das embarcações de pesca. Os dados georreferenciados apresentados cobrem as ações de fiscalização entre 2015 e 2022 e as rotas de tráfego e atividade pesqueira entre 2016 e 2022. O estudo concentra-se na Zona Económica e Exclusiva dos Açores e nas Áreas Marinhas Protegidas do Banco Condor, Princesa Alice e D. João de Castro. Para a região, foram desenvolvidas métricas para medir a Intensidade (ISK) da atividade pesqueira, que combina o número e o comprimento das embarcações de pesca por km2, para avaliar a pressão sobre os ecossistemas protegidos.
Os resultados indicam uma elevada intensidade das atividades de pesca nas áreas marinhas protegidas, destacando a pressão dos ecossistemas. As descobertas deste estudo têm como objetivo auxiliar as instituições reguladoras e investigadores na avaliação da intensidade da pesca e na promoção de uma gestão sustentável da pesca nos Açores, contribuindo para a preservação dos ecossistemas marinhos.
Portugal, as a country with an extensive coastline, has the responsibility to maintain active surveillance over the area within its maritime jurisdiction and sovereignty. It is essential to ensure that all vessels comply with current legislation and that the authorities responsible for enforcement have the necessary resources to carry out control activities. Given the growing concern for the sustainability of the fishing sector and species preservation, it is crucial to guarantee that vessels adhere to safety regulations and established fishing quotas to protect biodiversity. This study is based on the enforcement actions carried out by the Portuguese Navy on commercial fishing vessels and data from the Continuous Monitoring of Fishing Activity system. The analysis covers the temporal and geospatial aspects of maritime enforcement activities, using data that monitor the activity of fishing vessels. The georeferenced data presented cover enforcement actions between 2015 and 2022 and fishing traffic routes and activity between 2016 and 2022. The study focuses on the Exclusive Economic Zone (EEZ) of the Azores and the Marine Protected Areas of the Condor Bank, Princesa Alice, and D. João de Castro. For this region, metrics were developed to measure the Intensity (ISK) of fishing activity, combining the number and length of fishing vessels per square kilometer. The analysis shows that the intensity of fishing activities in the marine protected areas is very high, highlighting the pressure on protected ecosystems. The findings aim to assist regulatory institutions and researchers in assessing intensity and promoting sustainable fisheries management in the Azores to preserve marine ecosystems.
