WP7 carries out an integrated assessment of bycatch mitigation measures from ecological, social and economic perspectives.

In the Azores, our research contributes to:

📚 Developing best practices and guidelines for bycatch mitigation, and

🧮 Designing decision-support tools to help managers and policymakers prioritise actions.

This evaluation ensures that mitigation strategies are effective, feasible and sustainable, supporting informed management decisions for healthier marine ecosystems.

A espécie distribui-se entre 550 e 1.450 metros de profundidade, ocupando ambientes meso- e batipelágicos. Apresenta pele escura e surpreendentemente lisa, com escamas pouco visíveis, o que lhe confere o aspeto “aveludado” que inspira o nome comum.

Possui duas barbatanas dorsais com espinhos muito curtos e uma dentição diferenciada, com dentes superiores e inferiores distintos, característica típica de predadores adaptados a capturar e cortar presas nas zonas profundas.

🔎Curiosidade: sabem que a arreganhada de veludo era para nós a espécie de tubarão de profundidade dos Açores mais difícil de identificar? Através de métodos moleculares e taxonomia integrada conseguimos perceber quais as características mais facilmente observáveis para a distinguir das outras espécies durante as operações de pesca.

The species inhabits 550 to 1,450 metres in meso- and bathypelagic environments. It has dark, smooth skin with barely visible placoid scales, giving it the velvety texture that inspired its common name.

It bears two dorsal fins with very short spines and shows a differentiated dentition, with distinct upper and lower teeth, a trait common among deep-sea predators specialised in gripping and slicing prey.

🔎Interesting fact: Did you know that the velvet dogfish was, for us, the deep-sea shark species in the Azores that was most difficult to identify? Yet, through the use of molecular methods and integrated taxonomy, we have identified the characteristics that are most easily observable for distinguishing this species from other during fishing operations.

Under WP6, Marine Beacon focuses on developing and testing practical mitigation strategies to reduce bycatch and improve the survival of PETS.

In the Azores, our research explores:

📍 The effect of spatial and temporal closures to avoid encounters with PETS,

⚙️ Technical solutions to reduce interactions with fishing gear, and

💪 Post-release survival and best practices for handling.

These activities aim to translate scientific knowledge into effective, field-tested solutions that protect vulnerable species while supporting sustainable fisheries.

Entre as imagens recolhidas pelos nossos BRUVs ao longo das campanhas, surgem também encontros com várias espécies de raias que habitam as zonas profundas dos Açores.

No vídeo de hoje podemos ver dois das mais frequentes: 𝘋𝘪𝘱𝘵𝘶𝘳𝘶𝘴 𝘪𝘯𝘵𝘦𝘳𝘮𝘦𝘥𝘪𝘶𝘴 e 𝘙𝘢𝘫𝘢 𝘤𝘭𝘢𝘷𝘢𝘵𝘢.

A presença destas espécies recorda-nos a diversidade que caracteriza os ecossistemas profundos do arquipélago, onde cada uma desempenha o seu papel no fundo marinho.

🇬🇧

Among the BRUV footage gathered during our survey campaigns, we often come across several species of deep-water skates that inhabit the Azorean seafloor.

In today’s video, we can spot two of the most common ones: 𝘋𝘪𝘱𝘵𝘶𝘳𝘶𝘴 𝘪𝘯𝘵𝘦𝘳𝘮𝘦𝘥𝘪𝘶𝘴 and 𝘙𝘢𝘫𝘢 𝘤𝘭𝘢𝘷𝘢𝘵𝘢.

Their presence highlights the rich diversity of the deep ecosystems surrounding the archipelago, where each species plays its own role in life on the ocean floor.

WP5 develops next-generation monitoring tools to detect and track bycatch using artificial intelligence (AI) and molecular techniques (eDNA).

In the Azores, work includes:

💻 Testing AI-based systems for real-time bycatch detection,

🧬 Developing eDNA protocols to monitor fisheries bycatch and to identify rare and elusive species, and

📈 Comparing and refining innovative monitoring methods.

These advancements are paving the way for more accurate, efficient and scalable monitoring of PETS bycatch, a major step forward for marine research and conservation.

WP4 of Marine Beacon evaluates the risk of fisheries bycatch and the vulnerability of PETS to inform spatial mitigation strategies that balance conservation and fishery sustainability.

In the Azores, activities of the deep-water sharks research team include:

📍 Mapping high-risk bycatch areas,

⚖️ Assessing trade-offs between areas of protection and fishing opportunities and the vulnerability status of the main species caught as bycatch and

🧭 Validating risk models through collaboration with local fishers and datasets.

These analyses will contribute to a better understanding of how and where bycatch occurs, to a quantitative assessment of bycatch risk and support evidence-based decisions for fisheries management and species conservation.

Within the Marine Beacon project, WP3 aims to improve understanding of the distribution, abundance and bycatch occurrence of protected, endangered and threatened species (PETS) across all study regions.

In the Azores for the deep-water elasmobranchs, our research focuses on:

📊 Compiling and analysing existing data to identify key knowledge gaps, including a wide range of life-history traits, information about species ecology, conservation status, and many more, and

🎣 Estimating improved bycatch rates for the main species caught in local fisheries.

These efforts will help build a comprehensive picture of the currently available scientific knowledge and better quantify their interactions with local fisheries, as such helping to identify priorities in terms of data collection and monitoring, providing a foundation for more effective management and conservation strategies.

Marine Beacon is an ambitious project that aims to address many questions related to bycatch of PETS species. 🔎How? By developing innovative research and solutions, integrating new knowledge, and sharing it with all relevant stakeholders to maximise impact and uptake.

The project is organised into 8 𝗪𝗼𝗿𝗸 𝗣𝗮𝗰𝗸𝗮𝗴𝗲𝘀 (WPs), each of which includes several tasks. While the 2 first WPs relates to the project management and communication, WP3 to 8 are dedicated to science.

Over the next few weeks, we’ll be introducing each of these Work Packages. Here in the Azores, 𝗼𝘂𝗿 𝘁𝗲𝗮𝗺 𝗶𝘀 𝗮𝗰𝘁𝗶𝘃𝗲𝗹𝘆 𝗶𝗻𝘃𝗼𝗹𝘃𝗲𝗱 𝗶𝗻 𝘀𝗶𝘅 𝗼𝗳 𝘁𝗵𝗲𝗺: WP3, WP4, WP5, WP6, WP7 and WP8.

Stay tuned to learn more about the work we’re carrying out both at sea and on land! 🌊✨
