Article
The Azores (mid-north Atlantic) has a long history of artisanal multispecific fishery exploiting marine resources around the islands slopes and seamounts. Due to the archipelago´s oceanic character, demersal-deep-sea and pelagic-offshore species are central to local economy. However, a coastal subsistence fishery is also economically and culturally...
Preprint
Spearfishing is practiced by a small fraction of younger recreational fishers and has received considerably less scientific attention than angling. This knowledge gap may negatively affect the ability for developing sustainable marine recreational fisheries. We address this through a global systematic review of the literature pertaining to marine s...

This work is the result of an international research effort to determine the main impacts of the COVID-19 pandemic on marine recreational fishing. Changes were assessed on (1) access to fishing, derived from lockdowns and other mobility restrictions; (2) ecosystems, because of alterations in fishing intensity and human presence; (3) the blue econom...
Article
Marine recreational fishing (MRF) in Portugal is a traditional leisure activity with considerable importance for coastal populations. In the absence of available information from the national data collection framework, this article aims to review the existing information on MRF across the country. MRF was an open access fishery until recently, but...
Article
Full-text available
The presence of the opal chimaera, Chimaera opalescens , is reported for the first time in the deep waters of the Azores, with the capture of four specimens by fishermen and the video recording of an additional five individuals. Species identification was supported by the 646bp sequenced fragment of the mitochondrial gene cytochrome oxidase subunit...
Article
In contrast to the vast majority of European maritime territories, the Azores is an isolated oceanic archipelago in the North East Atlantic characterised by small-scale hooks-and-lines fisheries. Yet, in spite of the low environmental impact of such fishing gears, there is no solid integrative information on the discard practices. This study bridge...
Conference Paper
Fish monitoring effort has been increasing over the past years, due to conservation and management requests demanding more and accurate data and consequently with raising costs. This is an important challenge especially for remote and disperse locations where fish sampling poses unbearable costs, leading to limited spatial sampling schemes, limited...
Article
Full-text available
Marine recreational fishing (MRF) is a high-participation activity with large economic value and social benefits globally, and it impacts on some fish stocks. Although reporting MRF catches is a European Union legislative requirement, estimates are only available for some countries. Here, data on numbers of fishers, participation rates, days fished...
Article
Fishing experience and skills are not commonly considered in recreational fishery studies. To analyse potential different biological/ecological impacts of three experience levels of spearfishers (novice, intermediate and experienced), access point surveys were conducted over a period of 10 months in São Miguel Island (Azores archipelago). Groups di...
Technical Report

This document presents the main conclusions obtained in the 1st Workshop on Recreational Fishing on the Iberian Atlantic Coast, held on 11 and 12 November, 2016 in Vigo (Spain), within the framework of the RECREGES Project, "Research initiatives on recreational fisheries in Europe. Integration in the fisheries management models of the Galicia-North...
Article
Signs of changing marine ecosystems due to increasing human use of marine resources are recognised worldwide. Legislation and regulations are often at the core of fisheries management and harvesting control. However, these are ineffective without the respective compliance, often requiring an effective surveillance and enforcement in support of cons...
Article
Full-text available
To get a complete picture of how fish assemblages are affected by recreational fishing it may be necessary to combine daytime and nocturnal sampling. Most of the scientific literature on recreational fishing, however, neglects the nocturnal component. Discrepancies between daytime and night-time catches in a shore angling fishery in the mid-Atlanti...
Article
Full-text available
Understanding growth in living organisms is central to the study of individuals, populations and communities. In fisheries, in particular, growth modelling is fundamental to the management of fish stocks that can constitute important economic resources. The scientific literature is abundant in studies attempting to define the growth trajectory of d...
Article
Full-text available
Marine spatial management is an important step in regulating the sustainable use of marine resources and preserving habitats and species. The systematic conservation planning software “Marxan” was used to analyse the effect of different conservation objectives and targets on the design of a network of marine protected areas around two islands of th...
Article
Full-text available
Blackspot sea bream (Pagellus bogaraveo) is the most important economical resource of Azorean fisheries. Juveniles (age 0 and 1) were detected along island coastlines in nursery grounds that sheltered individuals of up to 13 cm (fork length). Juveniles occurred in coastal areas in all seasons, but higher catch per unit efforts occurred during summe...
Article
The decline of marine biodiversity can negatively affect the ocean's resilience, goods and services. Consequently, the identification and protection of biodiversity hotspots is often a priority in marine spatial planning. Marine protected areas (MPAs) can also be designated as fisheries management tools to promote sustainable fisheries. However, th...

The traditional species targeted by the Azorean demersal mixed hook-and-line commercial fisheries are presently facing a decline in captures, and the demand for new demersal resources is growing. The silver scabbardfish, Lepidopus caudatus, is a potential new resource to be exploited in the region; however, reports on its vulnerability and stock st...
Article
Full-text available
Bottom trawl fishing threatens deep-sea ecosystems, modifying the seafloor morphology and its physical properties, with dramatic consequences on benthic communities. Therefore, the future of deep-sea fishing relies on alternative techniques that maintain the health of deep-sea ecosystems and tolerate appropriate human uses of the marine environment...
Article
Recreational inshore fishing activities practiced on Faial and Pico Islands (Azorean archipelago) were surveyed between October 2004 and September 2005. Recreational inshore fishers employ three main methods of fishing (shore angling, spear fishing and intertidal collecting). The method that demanded the highest fishing effort (number of fishing op...
Article
Blue jack mackerel Trachurus picturatus monthly samples were collected between 1998 and 2011 to determine morphometric relationships, maturity, growth rates, reproduction and spawning seasonality in north-east Atlantic waters (ICES area Xa2). A total of 2895 specimens were sampled, ranging from 98 to 542 mm in fork-length (L F ). The morphometric r...

Background. Several studies have highlighted the negative potential of recreational boat fishing to put pressure on coastal fish species and in particular on those that are vulnerable. We focused on this problem launching the first such survey in the area on this type of fishery in the Azorean region. We were trying to assess the catch, harvest, an...
Article
This study was conducted in São Miguel Island (Azores archipelago) providing the first evidence from Macaronesia of spear fishing impacts on fish communities. The shoreline was monitored during 10 months by access point surveys where 220 fishers were interviewed and 27 target fish species were identified. Mean sizes of top predators and highly vuln...
