“…Contrary to the relatively well-known fish fauna of seamounts and islands around the Azores and Madeira (Arkhipov et al 2004;Christiansen et al 2009;Ehrich 1977;Kukuev 2004;Maul 1976;Menezes et al 2006Menezes et al , 2009Menezes et al , 2012Pakhorukov 2008;Santos et al 1997;Shcherbachev et al 1985), the ichthyofauna of the Horseshoe Seamount Chain (Fig. 1) and in particular of Ampère Seamount has been little studied until now.…”

“…Endemic species were not found. Except for the abyssal fishes Conocara salmoneum, Bathymicrops regis, Coryphaenoides profundiculus and Echinomacrurus mollis, all species have also been reported from waters around the Azores (Menezes et al 2006(Menezes et al , 2012Santos et al 1997). Of all species listed here, Conocara salmoneum is reported explicitly in Portuguese waters for the first time, but data from Merrett (1992) already suggest its presence in the Madeiran EEZ.…”

“…Although commercial fisheries have targeted many banks and seamounts, detailed scientific studies of the demersal and benthopelagic fish fauna are available only for a few of them. In particular, extensive sampling programmes were conducted at Great Meteor Bank and other seamounts south of the Azores (Ehrich 1977;Kukuev 2004;Maul 1976 and literature cited therein), and at Seine and Sedlo Seamounts (Christiansen et al 2009;Menezes et al 2009Menezes et al , 2012. Knowledge of the fish communities at Ampère Seamount is currently based on visual observations by Russian researchers covering the upper and middle slopes, but there is also anecdotal evidence that Ampère Seamount is a fishing ground for commercially valuable species, such as the black scabbardfish Aphanopus carbo (Bordalo-Machado et al 2009) and the silver scabbardfish Lepidopus caudatus (personal observation).…”

The fish fauna of Ampère Seamount (NE Atlantic) and the adjacent abyssal plain

An inventory of benthic and benthopelagic fishes is presented as a result of two exploratory surveys around Ampère Seamount, between Madeira and the Portuguese mainland, covering water depths from 60 to 4,400 m. A total of 239 fishes were collected using different types of sampling gear. Three chondrichthyan species and 31 teleosts in 21 families were identified. The collections showed a vertical zonation with little overlap, but indications for an affinity of species to certain water masses were only vague. Although most of the species present new records for Ampère Seamount, all of them have been known for the NE Atlantic; endemic species were not found. The comparison with fish communities at other NE Atlantic seamounts indicates that despite a high ichthyofaunal similarity, which supports the ''stepping stone'' hypothesis of species dispersal, some differences can be attributed to the local features of the seamounts.

Review of the Diversity, Ecology, and Conservation of Elasmobranchs in the Azores Region, Mid-North Atlantic

A vulnerable species group, such as, the elasmobranchs, in a data-deficient context presents a complicated management problem. Evidence suggests that the Azores islands, a remote archipelago on the Mid-Atlantic Ridge, serve essential functions in the life-history of species across taxa. The diversity of marine resources within its EEZ are exploited by local to international fleets, and the full extent of fishing pressure can often be underestimated. Although sharks and rays appear to be of minor importance in the fishery, the possibilities of illegal, unreported, and unregulated fishing raises concerns about these threatened species. However, this group has failed to attract management attention, visible in the lack of regional studies focused on biodiversity, ecology, or threats of elasmobranchs. Our work attempts to review and update the information on elasmobranchs of the Azores and identify potential threats, mainly by the local fisheries. We aim to highlight knowledge gaps that require further research and conservation actions. We (1) update the annotated checklist of elasmobranch species, (2) compare species distribution across a biogeographically similar section of the North Atlantic, and (3) analyze the interaction of elasmobranch species with local fisheries. We confirm 61 chondrichthyan species for the Azores (39 sharks, 17 rays, and 5 chimaeras), adding 19 species to the previous annotated checklist of 1997. The Azores elasmobranch species assemblage most resembles Madeira, the neighboring Macaronesian archipelago. Biogeographic affinities between the chosen regions of the North Atlantic are reflected in the taxonomic structure of families. Although underestimated in the local fisheries, elasmobranchs constitute a regular but highly variable portion of total landings. Misreporting and misidentification is perhaps the greatest concern in the local fisheries records, further aggravated by few existing catch regulations for elasmobranchs. Local knowledge indicates that the Azores serves as essential habitat for at least a few species in coastal areas and shallow seamounts, and potentially so for a number of deep-sea elasmobranchs. The intersection of fishery threats and local essential habitat functions around the archipelago warrants greater research effort and studies.
