Current and emerging small-scale fisheries and target species in Cabo Verde, with recommendations for pilot actions favouring sustainable development

Current and emerging small-scale fisheries and target species in Cabo Verde, with recommendations for pilot actions favouring sustainable development1126 DescargasFishing activity is a primary sector of great socioeconomic importance for the archipelago of Cabo Verde (eastern-central Atlantic), and has played a relevant role in strengthening food security, reducing poverty, job creation, balance of payments equilibrium […]

First report of an association of the deep-water hermit crab parapagurus pilosimanus (decapoda, parapaguridae) and the zoantharian epizoanthus from Macaronesia

First report of an association of the deep-water hermit crab parapagurus pilosimanus (decapoda, parapaguridae) and the zoantharian epizoanthus from Macaronesia184 DescargasHermit crabs are important ecosystem engineers (Jones et al., 1994) in marine habitats, from the intertidal to the deep sea. The symbiotic associates of hermit crabs were reviewed worldwide by Williams & McDermott (2004), and […]

Sex with the lights off: Can a morphological structure reveal the sex and functional sexual maturity in the genus Plesionika?

Sex with the lights off: Can a morphological structure reveal the sex and functional sexual maturity in the genus Plesionika?395 DescargasThe present work describes a taxonomic trait able to determine sex in pandalid shrimps of the genus Plesionika and an indicator of functional maturity in females. This structure is described as formed by two teeth […]

Disentangling exploitation of the intertidal grazer Phorcus sauciatus (Gastropoda: Trochidae) in an oceanic archipelago: Implications for conservation

Disentangling exploitation of the intertidal grazer Phorcus sauciatus (Gastropoda: Trochidae) in an oceanic archipelago: Implications for conservation317 DescargasHarvesting of intertidal grazers such as topshells is known to affect negatively the exploited populations by altering population structure and decreasing abundance. Phorcus sauciatus has a wide geographic distribution in the North‐eastern Atlantic Ocean and is subject to […]

Changes in catch and bycatch composition and in species diversity of a semi-floating shrimp-trap fishery in three eastern Atlantic island ecosystems with different degrees of human alteration

Changes in catch and bycatch composition and in species diversity of a semi-floating shrimp-trap fishery in three eastern Atlantic island ecosystems with different degrees of human alteration414 DescargasComposition and bycatch of semi-floating shrimp-trap fisheries (SSTF) were compared among areas with different levels of anthropogenic alteration of marine ecosystems. The three areas selected were Madeira, the […]

Checklist of brachyuran crabs (Crustacea: Decapoda) from the Cape Verde Islands, with a biogeographic comparison with the Canary Islands (Eastern Atlantic)

Checklist of brachyuran crabs (Crustacea: Decapoda) from the Cape Verde Islands, with a biogeographic comparison with the Canary Islands (Eastern Atlantic)358 DescargasIn the current scenario of defaunation and bioinvasion, increasing the knowledge about the composition in marine species and monitoring are an emergency need to control the biodiversity. Nearly 35 years have passed since Türkay […]

An Atlantic journey: The distribution and fishing pattern of the Madeira deep sea fishery

An Atlantic journey: The distribution and fishing pattern of the Madeira deep sea fishery387 DescargasThe deep sea fishery targeting the black and intermediate scabbardfishes (Aphanopus spp.) off the Madeira archipelago represents one of the world long standing exploitations of meso- and bathypelagic fishes. The intensive fishing of the target species caused an overall decrease of […]
