We’re continuing to share the research presented by the TubaProf team at the European Elasmobranch Association 2026 (EEA2026)! Today, we’re highlighting the studies presented by Leonor Mendonça and Laurence Fauconnet.

🦈 Leonor studied the vulnerability of two deep-water shark species to bottom longline fishing in the Azores, including local fishermen’s knowledge in the assessment. The significant changes in the results after adding this knowledge highlight the importance of working with the fishing sector to improve scientific assessments, especially when data are limited.

💡 Laurence presented experiments to test whether LED lights of different colours can help reduce the bycatch of deep-water elasmobranchs. The results show that their responses vary depending on the colour of the light and the species, opening up new possibilities for developing measures to reduce bycatch.

Congratulations to all four team members on your research and participation in the conference! 👏

On 6, 7 and 8 October, the congress of the European Elasmobranch Association (EEA) 2026 took place. This edition was held online, where four members of TubaProf had the opportunity to share their research. 👏

📷 Judit Nieto presented a poster with the latest progress on the use of BRUVs to study deep-water elasmobranchs in the Azores. The poster presents the results based on 500 hours of BRUV recordings collected so far, that have allowed the team to observe numerous species in their natural habitat, as well as to locate a nursery area of a rare shark species. It also includes the recent progresses exploring the use of AI to speed up the analysis of these videos.

🗺 Guillaume Beauvois presented a study on the distribution of commercial species and deep-water elasmobranchs to identify areas where bycatch could be reduced with the lesser possible impact on fishing activities. Based on these data, maps were created to identify the most suitable areas for fishing and those where fishing should be avoided.

👉 In the next post, we will share more about the other two TubaProf studies presented at the conference.

Well done!

🌍🌊 TubaProf at the ICES Annual Science Conference

From 15 to 18 September, the ICES Annual Science Conference 2026 took place in Brest (France) where Laurence Fauconnet, researcher at OKEANOS and co-leader of the TubaProf research group, participated. During the session focused on bycatch reduction, Laurence gave a talk entitled:

“Bridging the Implementation Gap: Best Practices to Promote the Uptake of Selectivity Measures in EU Fisheries”

🔎 Although many selectivity measures have been tested in recent years to reduce bycatch, their adoption in commercial fisheries is still limited.

🎣 In her presentation, Laurence highlighted some of the main factors that can help the implementation of these measures: close collaboration with fishers, better recognition of fishers who use these measures, the development of solutions adapted to the characteristics of each fishery, appropriate incentives and effective communication of the results.

These events are a great opportunity to share knowledge, learn from other projects and continue building solutions together with the fishing sector.

🇵🇹

Hoje apresentamos o Guillaume Beauvois, um estudante que realizou um estágio connosco no âmbito do seu mestrado.

Neste âmbito, Guillaume contribuiu para a identificação de zonas de compromisso para a pesca de fundo nos Açores, com o objetivo de limitar as capturas acessórias (bycatch) de elasmobrânquios de águas profundas e, ao mesmo tempo, otimizar as capturas de espécies comerciais.

Para isso, utilizou modelos de distribuição de espécies previamente desenvolvidos para criar mapas preditivos multiespecíficos, que permitem avaliar a sobreposição na distribuição destas espécies. Estes mapas podem servir para informar quais das áreas da Zona Econômica Exclusiva (ZEE) dos Açores são melhores para pescar espécies comerciais e ao mesmo tempo evitar as capturas de elasmobrânquios.

Desejamos-te muito sucesso no teu trabalho, Guillaume!

🇬🇧

Today, we introduce Guillaume Beauvois, a student who completed an internship with us as part of his Master’s degree.

During his internship, Guillaume contributed to identifying trade-off areas for bottom fisheries in the Azores, in order to limit the bycatch of deep-water elasmobranchs while, at the same time, optimizing the catch of commercial species.

To do so, he used pre-existing species distribution models to create multispecies predictive maps, which allow us to assess the overlap in the distribution of these species. These maps can help identify which areas of the Azores Exclusive Economic Zone (EEZ) are more suitable for fishing commercial species while avoiding the bycatch of elasmobranchs.

We wish you the best of luck with your work, Guillaume!

As we introduced in our previous post, our recent work on board as part of the Marine Beacon project was divided into four main areas:

🎣 Selectivity
We carried out fishing trials to test how different devices can reduce shark catches with deep-sea bottom longlines. This helps us identify possible ways to reduce bycatch.

🦈 Survival
We tagged the sharks before releasing them back into the sea. These tags allow us to study the post-release survival of tagged individuals.

🧬 Genetic monitoring
We collected DNA samples from captured sharks to confirm species identification and contribute to the study of deep-sea shark species and populations, and collected eDNA samples to test it as a monitoring method for deep-water sharks.

🎥 Video monitoring
We collected images from an onboard camera to test this method for bycatch monitoring, and underwater images with our BRUV to test it for monitoring methods of deep-water sharks.

Esta semana apresentamos a Judit Nieto, a nossa assistente de investigação que trabalha no estudo dos tubarões e raias de águas profundas nos Açores.

A Judit realizou anteriormente um estágio connosco e, em Junho de 2026 regressou à equipa. O seu trabalho inclui a análise de vídeos subaquáticos obtidos através de BRUVs, que permitem estudar a presença e compreender o comportamento dos tubarões de águas profundas no seu ambiente natural. Também participa em campanhas de pesca para analisar o impacto do bycatch nestas espécies e para recolher amostras de ADN ambiental (eDNA), que contribuem para a identificação e monitorização das espécies de águas profundas dos Açores.

Muito obrigada, pelo teu trabalho e por todo o teu contributo para a equipa TubaProf!

🇬🇧

This week we introduce Judit Nieto, our research assistant, who works on the study of deep-sea sharks and rays in the Azores.

Judit previously completed an internship with us, and in June 2026 she rejoined the team. Her work includes analysing underwater videos collected through BRUVs, which allow us to study the presence and understand the behaviour of deep-sea sharks in their natural environment. She also takes part in fishing surveys to study the impact of bycatch on these species and to collect environmental DNA (eDNA) samples, which contribute to the identification and monitoring of deep-sea species in the Azores.

🔎🛥️ TubaProf’s fishing experiments in Marine Beacon project

Between the 31st of July and the 27th of August, we were at sea to carry out a fishing survey as part of the Marine Beacon project. During the survey, we put different research approaches into practice: fishing experiments to test bycatch reduction measures, tagging experiments to study post-release survival of deep-water sharks in bottom longline fisheries, along with DNA, eDNA and imaging collection for monitoring purposes.

In the next post, we’ll take a closer look at each part of our work!

🇵🇹

Temos o prazer de introduzir à Emily Fitzgerald, que está a realizar a sua dissertação de mestrado connosco, no âmbito do Mestrado Internacional em Ambiente Marinho!

A Emily está a trabalhar connosco desde abril, e a sua dissertação centra-se na comparação de métodos, baseados no desenho amostral e em modelos, para estimar as capturas acessórias de elasmobrânquios de águas profundas nas pescarias de anzol e linha dos Açores. O seu trabalho procura avaliar o desempenho destas abordagens, de forma a melhorar a nossa quantificação das capturas acessórias nas pescarias regionais e contribuir para a gestão e conservação destas espécies.

Depois de todo o seu trabalho e dedicação, a Emily irá defender a sua dissertação na próxima semana, de 7 a 10 de setembro. Desejamos-lhe muita sorte nesta reta final!

🇬🇧

We are pleased to introduce Emily Fitzgerald, who is doing her Master’s thesis with us as part of the International Master in Marine Environment (MER)!

Emily has been working with us since April, and her thesis focuses on comparing design- and model-based methods to estimate deep-water elasmobranch bycatch in Azorean hook-and-line fisheries. She is examining how these approaches perform to improve our quantification of bycatch and inform management and conservation.

After all her hard work, Emily will defend her thesis next week, from September 7th to 10th. We wish her the very best of luck during this final stretch!
