Structure and zonation of demersal fish assemblages off the Azores Archipelago (mid-Atlantic)
The assemblages of the demersal fish fauna of the Azores Archipelago are described from longline surveys that extended from the coastline to 1200 m water depth. A total of 104 fish spe- cies from 47…
Intra- and inter-specific variability in total and methylmercury bioaccumulation by eight marine fish species from the Azores.
Demersal fish assemblages off the Seine and Sedlo seamounts (northeast Atlantic)
Genetic population structure in the black-spot sea bream (Pagellus bogaraveo Brünnich, 1768) from the NE Atlantic
This study supports studies on other deep-sea fish species that indicate that hydrographic or topographic barriers prevent dispersal of adults and/or larvae between populations at regional and oceanographic scales.

Age and growth of the forkbeard were studied using 477 otoliths from individuals caught between April 2000 and August 2004, and the von Bertalanffy growth parameters estimated were L∞ = 79.64 cm, k = 0.09 yr−1 and t0 = −1.88 years.
New contribution to the reproductive features of bluemouth Helicolenus dactylopterus dactylopterus from the northeast Atlantic (Azores Archipelago)
The annual changes in the gonad, together with the analysis of the monthly gonadosomatic indices, and complementary observations with scanning electron microscopy, allow us to conclude that the females are internally inseminated between July and November and spawn between January and March.
Some aspects of the biology of the deep-water crab, Chaceon affinis (Milne-Edwards and Bouvier, 1894) off the Azores
Sex and reproduction of the alfonsino Beryx splendens (Pisces, Berycidae) from the Macaronesian archipelagos
Comparisons on the reproductive biology of the alfonsino, Beryx splendens Lowe, 1834, species with commercial interest in the Azores, Madeira and the Canary Islands suggest that this species has a specialistic life-history strategy and fisheries based on this species are more susceptible to growth overfishing and population depletion.
