Designing a coastal monitoring marine biodiversity survey, using trammel nets a...

Although coastal areas are of great importance, they often lack long term monitoring surveys, which are essential for effective management, fisheries sustainability, and marine spatial planning. To address this, we conducted two experimental surveys aimed at assessing communities and their biodiversity, with the objective of designing a monitoring program for marine coastal biodiversity, based on gear type, dep...

Genomics goes deeper in fisheries science: The case of the blackspot seabream (...

Recent advances in genomics are an essential contributor to the assessment of fish stocks by providing a finescale identification of the species’ genetic boundaries. The blackspot seabream, Pagellus bogaraveo, is a commercial sparid distributed across the northeast (NE) Atlantic and the Mediterranean. Within the NE Atlantic, three P. bogaraveo stocks are currently defined: Azores; Atlantic Iberian waters; Celti...

Vulnerable marine ecosystems survey pilot missions with EVA Hybrid AUV/ROV

Fishing for deep-sea species occurs on continental slopes, ridges, and seamounts. Fishing operations using fishing gears that contact the bottom (e.g., trawls and bottom longlines) may have significant impacts on Vulnerable Marine Ecosystems (VMEs). VMEs refer to marine ecosystems with a population or community of sensitive taxa or habitats that are likely to experience substantial alteration from short-term to...

Dataset of the complete mitogenome of the deep-sea sailfin roughshark, Oxynotus...

Chondrichthyans comprise a diverse group of vertebrate species with extraordinary ecological relevance. Yet, multiple members of this evolutionary lineage are associated with sig-nificant extinction risk. The sailfin roughshark Oxynotus para-doxus is a deep-water benthic shark currently listed as vul-nerable due to population declines in parts of its range. Here we provide the first complete mitochondrial genom...

Adapting the sampling design of research surveys to improve the biomass estimat...

Research surveys are important to evaluate the spatial distribution of fishery re sources and to monitor their abundance. However, the underlying sampling is usually conceived with the focus on specific species and an efficient design may reconcile this objective with the collection of non-target species data. This study evaluates the adequacy of different sampling designs for the IPMA bottom trawl survey condu...

This report presents the stock assessment results for the species exploited by Portugal in 2020 and the scientific advice for their management in 2021. For each resource the stock distribution area, the source for the scientific advice, the biological reference points, the state of exploitation and scientific advice and the management measures.; O presente relatório apresenta os resultados das avaliações do est...

ESTADO DOS STOCKS EM 2018 E ACONSELHAMENTO CIENTÍFICO PARA A SUA GESTÃO EM 2019

This report presents the stock assessment results in 2018 for the species exploited by Portugal and the scientific advice for their management in 2019. For each resource the stock distribution area, the source for the scientific advice, the biological reference points, the state of exploitation and scientific advice and the management measures. The current RCT-IPMA reports information previously made available ...

Genetic population structure of the Blackspot seabream (Pagellus bogaraveo): co...

Marine fisheries management models have traditionally considered biological parameters and geopolitical boundaries. The result is the existence of fisheries management units that do not match genetic populations. However, this panorama is changing with the contribution of genetic and genomic data. Pagellus bogaraveo is a commercially important sparid in the northeast Atlantic, with three stock components being ...
