“…1). This area (40 km 2 ) was ideal for our study because the main economic activity is fishing and fish mongering, the presence of sea turtle (olive ridley, leatherback, and green) nesting year round (primary nesting season September through February), and there is evidence of increasing interactions between fisheries and sea turtles (Ntiamoah-Baidu & Gordon 1991;Agyekumhene et al 2017;Alexander et al 2017). Furthermore, monthly mean sea surface temperature varies from 22.9°C (August) to 30.1°C (April) across seasons but does not vary within the study area (Freeman et al 2017).…”

The growing demand for fish around the world is an immediate threat to marine megafauna that are unintentionally captured in commercial and artisanal fishery operations. Bycatch mitigation strategies, such as turtle excluder devices, circle hooks, and net illumination, have successfully reduced this risk in some fisheries. We explored the effectiveness of gillnet illumination to reduce sea turtle captures in 2 artisanal fisheries (Mankoadze and Winneba, Ghana) under normal fishing conditions. We first quantified sea turtle bycatch in Ghana's artisanal gillnet fishery from 15 boats for 12 months. We then quantified catch of targeted species and sea turtle bycatch from 20 boats for 15 months (7427 net sets). For 10 of these boats, we placed a Centro Economy green light (1 LED) at each 10-m interval on the net. We also quantified target catch and sea turtle bycatch from 30 boats for 8 months (2250 net sets). In 15 of these boats, a Centro Deluxe green light (3 LEDs) was installed at 15-m intervals. Boats with economy lights and those with deluxe lights both exhibited an 81% decrease in sea turtle captures (W = 1, p < 0.001, n = 20; W = 215, p < 0.001, n = 30, respectively) compared with control boats without lights. Illuminated nets resulted in fewer turtle catches for leatherback (Dermochelys coriacea), olive ridley (Lepidochelys olivacea), and green sea turtles (Chelonia mydas) (p < 0.05 for all species). Target catch (mass) (W = 53, p = 0.853 n = 20; W = 76, p = 0.449, n = 23) and value (W = 50, p = 1, n = 20; W = 69, p = 0.728, = 23) were not different across treatments. Our study affirms net illumination can reduce capture rates of 3 species of sea turtles, including the imperiled leatherback. Gear modification methods can successfully reduce bycatch if they are affordable and have broad applications for multiple species in different fisheries.

“…As relações entre os conhecimentos populares e os recursos alimentares consumidos foram apontadas em diversos trabalhos (Batista et al 2016, Alexander et al 2017, Giglio et al 2018, como informações importantes a serem consideradas em diagnósticos de uso de recursos, contribuindo, por exemplo, para a elaboração de planos de manejo, acordos de uso, etc. Instrumentos de gerenciamento do uso de recursos naturais são fundamentais para reduzir a degradação ambiental, perda de biodiversidade e consequências socioeconômicas para comunidades locais (Pegas et al 2015).…”

The archipelago of Fernando de Noronha is divided into a National Marine Park, intended for the protection of natural resources and an Environmental Protection Area, where human occupation is permitted. Tourist use has caused changes in the island lifestyle, mainly in relation to economic activities and contact with nature. Thus, the present study aimed to analyze the local knowledge and eating habits of the people of Noronha, their preferences and aversions regarding the consumption of fish in the Archipelago of Fernando de Noronha/PE. Data collection was carried out through individual interviews using a script and these were analyzed quantitatively and qualitatively. It was found, in the research carried out with 81 interviewees, that the preferred fish for consumption are black syrup (Caranx lugubris), piraúna (Cepholopholis fulva), yellowfin (Thunnus albacares), barracuda (Sphyraena barracuda), anchovy (Pomatomus saltatrix), red snapper (Lutjanus spp.) and mackerel (Acantocybium solandri). The relationship between popular knowledge and consumed food resources indicates an important contribution to regional and local conservation initiatives, which are essential to reduce environmental degradation, loss of biodiversity and socioeconomic consequences for local communities. Aversion to reymosed fish was confirmed, such as cangulo (Melichthys niger) and barracuda (Sphyraena barracuda), corroborating with the knowledge found in the literature. Thus, the use of fish in the diet of the residents of Fernando de Noronha showed patterns already indicated in research with other fishing communities where preference, taboos and medicinal use are the main purposes and indicate the knowledge they have about the environment and the available resources

“…A non-probability convenience sampling approach (Alexander et al, 2017) was employed to select fishers and traders for the interview. The convenience sampling approach also referred to as availability sampling is based on the availability and willingness of respondents to participate in the interview (Naderifar et al, 2017;Newing, 2010).…”

Small-scale shark fisheries support a large number of coastal community livelihoods in developing countries. Shark meat comprises a cheap source of protein and is traded locally in many parts in developing countries, while the skins, oil, fins and gill rakers are exported to the international market. This study addresses a gap in literature regarding the importance of elasmobranchs to key shark-fishing communities and the degree to which trade in shark products (meat and fins) vary in time and among fishing communities in Ghana. We interviewed 85 fishers and traders involved in shark fisheries in Axim, Dixcove, and Shama communities using semi-structured questionnaires. Fishing was the primary source of income and accounted for 59.9% of the total household income of respondents. Other important economic activities were fish processing (15.2%), fish retailing (14.8%), and small businesses (2.9%). One-third and often two-thirds of respondents generated between 80-100% of their income from shark fisheries: Axim (n = 65%), Dixcove (68%), and Shama (35%). Shark meat consumption was common among fishers and traders and represents a substantial source of protein in the diet of the study communities. Overexploitation of these species may compromise food security. Hammerhead Sharks (Sphyrna spp) and Bull Shark (Carcharhinus leucas) have the most valuable fins and meat. Further, 75% and 95% of fishers and traders respectively see fishing and trading of shark meat as their last safety-net and, therefore, tend to be satisfied with their jobs. Non-fishing related livelihood streams including small businesses and transportation were the major fallback activities both fishers and traders preferred to rely on if there is a ban on the exploitation of sharks in Ghana. Thus, any shark management strategy must take into consideration the preferred livelihood fallback options outlined by fishers and traders, and implement them to ensure the success of the intervention.
