Artisanal fisheries in the Canary Islands (Eastern-Central Atlantic): Description, analysis of their economic contribution, current threats, and strategic actions for sustainable development

Fishing is a primary activity of great importance in the Canaries and has traditionally played an important role in reducing poverty, in job creation, strengthening food security and sovereignty, and increasing the value of its products. This study is needed to analyze fishing contribution in a region strongly based on tourism. Aims were: to update the inventory of fishing techniques, to detail the biodiversity involved, and for the first time to analyze the contribution of the landings. We also identify threats to the activity and draft a plan with strategic actions for its sustainability.

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

Fishing 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 and Gross Domestic Product. So, this review was needed to make small-scale fisheries visible in a Developing Island Country with a fast-growing tourist industry.

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

Hermit 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 over 550 invertebrates, from 16 phyla, were found associated with over 180 species of hermit crabs. Many studies have been focused on hermit crab-actiniarian associations, while hermit crab-zoantharian symbioses have received less attention (Kise et al., 2019).

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

The 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 more than (51%) in their yields.

Checklists of Crustacea Decapoda from the Canary and Cape Verde Islands, with an assessment of Macaronesian and Cape Verde biogeographic marine ecoregions

The complete list of Canarian marine decapods (last update by González & Quiles 2003, popular book) currently comprises 374 species/subspecies, grouped in 198 genera and 82 families; whereas the Cape Verdean marine decapods (now fully listed for the first time) are represented by 343 species/subspecies with 201 genera and 80 families.

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

In 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 (1982) published the decapod crustaceans of the Cape Verde islands,

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

Composition 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 Canary Islands and Cape Verde. Mean species richness and diversity of the SSTF did not show significant differences among areas.

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

Harvesting 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 increasing levels of harvesting pressure due to the expansion of human population on coastal areas.

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

The 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 with abundant setae present in all males of the nine Plesionika species examined.
