RESUMEN La sobrepesca, la pesca industrial y el cambio climático generan impactos que afectan al recurso pesquero marino, la principal fuente de ingreso y alimento de las poblaciones costeras de pescadores artesanales. La creación de condiciones que incrementen la capacidad de adaptación de los pescadores disminuirá su vulnerabilidad a los impactos. Esta investigación propone determinar una Zona Exclusiva de Pesca Artesanal-ZEPA como estrategia de manejo sostenible de los recursos pesqueros y de adaptación climática para los pescadores artesanales del área de estudio. Se utilizó el programa Marxan para identificar tres escenarios para la ubicación de la ZEPA y se realizó una cartografía participativa con pescadores para obtener el cuarto escenario. Se encontró similitud alta entre el escenario 2 y 4, lo que muestra que el enfoque científico (Marxan) y participativo (población) coinciden en la ubicación de ZEPA. La ZEPA definitiva se ubicó en la zona marino costera de los municipios de Tumaco y Francisco Pizarro, con un área total de 2 008 km2. Incluyó objetos de conservación importantes para la pesca artesanal como caladeros de pesca artesanal, ecosistemas (manglares, playas y estuarios), áreas de ocurrencia de especies (sierra, pargos, corvina, piangua, camarón tití), entre otros. Se identificó que más de 80 % de los pescadores estuvo de acuerdo en que la estrategia le aportaría a reducir su vulnerabilidad frente a amenazas como fenómenos climáticos, sobrepesca, contaminación, entre otros. Se resalta la contribución a la adaptación al cambio climático de la población del área de estudio.

ABSTRACT Overfishing, industrial fishing and climate change generate impacts that affect the marine fishery resource, the main source of income and food for coastal populations of artisanal fishers. The creation of conditions that increase the adaptive capacity of fishers will decrease their vulnerability to impacts. This research proposes to determine an Exclusive Zone for Artisanal Fishing-ZEPA as a strategy for sustainable management of fishery resources and climate adaptation for artisanal fishers in the study area. Marxan was used to identify three scenarios for the location of the ZEPA and participatory mapping was carried out with fishers to obtain the fourth scenario. High similarity was found between scenarios 2 and 4, which shows that the scientific (Marxan) and participatory (population) approaches coincide in the location of the ZEPA. The final ZEPA was located in the coastal marine zone of the municipalities of Tumaco and Francisco Pizarro, with a total area of 2,008 km2. Included important conservation targets for artisanal fisheries such as artisanal fishing grounds, ecosystems (mangroves, beaches and estuaries), areas of occurrence of species (seerfish, snappers, sea bass, piangua, marmoset shrimp) among others. More than 80 % of the fishers agreed that the strategy would help reduce their vulnerability to threats such as climatic phenomena, overfishing, pollution, among others. The contribution to climate change adaptation of the study area’s population is highlighted.

ABSTRACT Food availability is defined as the sufficient quantity of food of adequate quality and culturally acceptable for the population of a country in a given period. In the case of the cities of the North Coast of the Uruguay River, there is little availability in terms of local fishing. The objectives of this research were to analyze the causes of this scarce availability through the opinion of the artisanal fishermen of the region, and the referring institutions. Semi-structured interviews were conducted with artisanal fishermen and institutional references in the region, as well as a representative of the private sector. The inability of fishermen to dedicate themselves exclusively to the activity; the export destination that has the majority of the region's catches; the low consumption at national level and the scarce demand of the cities for river fish, were some of the enunciated causes.

RESUMEN La disponibilidad de alimentos se define como la cantidad suficiente de alimentos de calidad adecuada y culturalmente aceptables para la población de un país en un período determinado. En el caso de las ciudades del Litoral Norte del Río Uruguay, se observa una escasa disponibilidad en materia de pesca local. Los objetivos de esta investigación fueron analizar las causas de esta escasa disponibilidad a través de la opinión de los y las pescadores artesanales de la región, y las instituciones referentes. Se realizaron entrevistas semi estructuradas a pescadores artesanales y referentes institucionales de la región, así como a un representante del sector privado. La imposibilidad de los pescadores para dedicarse exclusivamente a la actividad; el destino exportador que tiene la mayoría de las capturas de la región; el bajo consumo a nivel nacional y la escasa demanda de las ciudades por pescado de río, fueron algunas de las causas enunciadas.

Abstract Colonial domination, established from the 15th century onwards, remains as a founding element of modern western rationality,, acting as invisibly as efficiently in the production of subalternities. In the epistemological dimension, the coloniality of knowledge institutionalizes the role of modern science in the discrimination of knowledge between false and true. Decolonization as an unfinished project, associated with authoritarian fisheries management models, has forged contexts of environmental injustice. As a factual example, we analyze the imposition of a period of suspension of fishing activity in Lagoa de Araruama-RJ, based on the narratives of the artisanal fishing community of Praia do Siqueira, located on its banks. In developing the research, non-extractive/participatory methodologies were used. It is concluded that the imposed calendar intensifies the processes of deterritorialization of the community, however, despite the violence, these spaces are percolated by r-existence practices. domination th onwards rationality rationality, subalternities dimension true project models injustice example AraruamaRJ, AraruamaRJ Araruama RJ, RJ Araruama-RJ Siqueira banks research nonextractive/participatory nonextractiveparticipatory non extractive/participatory extractive participatory used however violence rexistence r existence practices nonextractive extractiveparticipatory

Resumen: En | Texto: En | PDF: En

Abstract This paper describes the fishing profile and the temporal variation in the commercial landings of elasmobranchs in a global hotspot for their conservation and investigates the variables that influenced the landings. Census data on commercial catches were obtained between April 2008 and October 2010 from nine landing sites in Bragança (Pará, northern Brazil). Five vessel types, four fishing gears, and eight fishing techniques engaged with elasmobranch capture were identified. A total of 2,357 landings were recorded, with a total production of 354 t. The highest yields were recorded in 2009, with sharks being harvested mostly by small and medium-sized vessels, and batoids, by small vessels and canoes. Drifting nets and longlines played a prominent role in elasmobranch fisheries. The results show that the landings were influenced by days at sea, which is common in tropical fisheries. The elasmobranch data series is discontinuous as statistics are absent for most fishing sites albeit imperative for proper management, as well as relevant for decision-makers focusing on their conservation. 200 201 Pará, Pará (Pará Brazil.

Resumen: En | Texto: En | PDF: En

Abstract It is commonly assumed that beach seining (BS) is more sustainable than bottom trawling because it involves non-motorized operations and limited fishing power. However, no scientific evidence supports this assumption. To address this gap, we evaluated the impact of beach seining, taking a small-scale shrimp fishery in northeast Brazil. Data collected monthly from December 2016 to November 2017 and in literature, were assessed (BS 31,001 individuals, 119 species, 37 families, and 19 orders; BT 6,031 individuals, 58 species, 20 families, and 14 orders). Beach seining demonstrated a lower proportion of bycatch (BS 1:2.3; BT 1:3.2), higher total shrimp catch (BS 87.2 t; BT 65 t), and greater species diversity than bottom trawling catches (BS 119; BT 58). Other aspects were closer associated with bottom trawling, such as the composition of dominant families (Sciaenidae and Pristigasteridae), the proportion of rare species (BS 30%; BT 24%) juveniles (BS 11g; BT 13g), the risk of species extinction, and the composition of ecological guilds. Despite their social significance, both fishing gears showed similar ecological indicators and adverse effects. The findings establish that the ecological concerns related to the impact of bottom trawling are also applicable to beach seine.

RESUMO: Este artigo apresenta um estudo experimental para verificar a viabilidade de uso da tecnologia emergente UAV no mapeamento dos pesqueiros explotados pela pesca artesanal na Baía de Sepetiba, no sul do estado do Rio de Janeiro-Brasil, visando conhecer melhor a funcionalidade e informações geradas pelo equipamento, e se os dados poderão auxiliar na melhoria do gerenciamento da pesca local e também subsidiar informações para a implantação de uma rastreabilidade simplificada para o pescado regional. A área de estudo contemplou quatro localidades sendo Ilha da Madeira, Vila Geny, Coroa Grande e Ponte Preta, todas inseridas na Baía de Sepetiba, localizada no município de Itaguaí, região sul do estado do Rio de Janeiro. O mapeamento aéreo foi realizado nos meses de setembro, outubro e novembro de 2017, entre 10h e 12h (GMT-3), utilizando um VANT Phantom 3 Professional (DJI, Shenzhen, China), registro Anac Brasil PP-011092014. A câmera integrada é uma DJI 4K Edition Sony Exmor R Modelo IMX117: 7,81 mm equipada com sensor CMOS de 6,2 mm, resolução 4000 x 3000 de 12 megapixels, com lente f/2.8 e campo de visão (FOV) de 94, possuindo uma distância focal de 14 mm. As imagens foram coletadas perpendicularmente ao plano principal. A altura de voo foi fixada em 80 m, a velocidade de voo foi determinada com base na sobreposição de 80%, dimensão da área a ser mapeada e duração da bateria. Assim, o operador utilizou uma velocidade média de voo de 25 km/h. a distância da amostra terrestre (GSD) foi de 1,20 cm/px. e foi estabelecida uma sobreposição de 80% entre as imagens para evitar possíveis falhas e lacunas de informações do ortomosaico. Para cada pesqueiro mapeado foi realizado o processamento padrão do software, que consiste em: alinhamento das fotos, criação da nuvem de pontos, criação de modelo de elevação digital, e finalmente o ortomosaico propriamente dito. Uma vez processado, os ortomosaicos foram exportados do Agis Soft Photo Scan Professional para o Google Earth (Google Inc.), onde é possível fazer uma avaliação mais abrangente dos pesqueiros de uma maneira muito mais prática e rápida. Foram realizados um total de quatro voos, um para cada área de estudo, com duração média de 10 minutos cada. Como resultado, a tecnologia mostrou-se viável de aplicação, uma vez que possibilitou identificar e mapear as áreas definidas para nesta pesquisa, gerando dados como distância e características do local, que poderão ser utilizados para rastrear o pescado capturado e desembarcado, além de possibilitar o monitoramento das embarcações e da pesca e assim, aprimorar o gerenciamento da pesca local.

ABSTRACT: This article presents an experimental study to verify the feasibility of using the emerging UAV technology in the mapping of fishing grounds exploited by artisanal fishing in Sepetiba Bay, in the south of the state of Rio de Janeiro-Brazil, aiming to better understand the functionality and information generated by the equipment, and whether the data can help improve local fisheries management and also provide information for the implementation of simplified traceability for regional fish. The study area included four locations, Ilha da Madeira, Vila Geny, Coroa Grande and Ponte Preta, all located in Sepetiba Bay, located in the municipality of Itaguaí, in the southern region of the state of Rio de Janeiro. The aerial mapping was carried out in September, October and November 2017, between 10 am and 12 pm (GMT-3), employing a Phantom 3 Professional UAV (DJI, Shenzhen, China), Anac Brasil registration number PP-011092014. The onboard camera a DJI 4K Edition Sony Exmor R Model IMX117: 7.81mm equipped with a CMOS sensor dimension of 6.2 mm, 4000 x 3000 12 megapixel resolution, with an f/2.8 lens and field of view (FOV) of 94, having a focal length of 14mm. Images were collected perpendicularly to the main plan. Flight height was set at 80 m, flight speed was determined based on the overlap of 80%, dimension of area to be mapped, and battery life. Hence, the operator utilized a average flight speed of 25 km/h. ground sample distance (GSD) was 1.20 cm/px. and an overlap of 80% between images was established to avoid possible failures and orthomosaic information gaps. For each fishery mapped, standard software processing was carried out, which consists of: aligning the photos, creating a point cloud, creating a digital elevation model, and finally the orthomosaic itself. Once processed, the orthomosaics were exported from Agis Soft Photo Scan Professional to Google Earth (Google Inc.), where it is possible to make a more comprehensive assessment of fisheries in a much more practical and faster way. A total of four flights were carried out, one for each study area, averaging 10 minutes each. As a result, the technology proved to be viable to apply, since it made it possible to identify and map the areas defined for this research, generating data such as distance and, characteristics of the place, which could be used to track the fish caught and landed, in addition to enabling the monitoring of vessels and fishing, and thus improve the management of local fisheries.

O programa BIOTA/FAPESP foi criado nesse contexto e é uma iniciativa de sucesso para promover estudos em biodiversidade e conservação no Brasil. O BIOTA/Araçá é um projeto interdisciplinar que promoveu uma avaliação detalhada da biodiversidade da Baía do Araçá, um ecossistema costeiro localizado ao Norte do estado de São Paulo, Sudeste do Brasil. A baía engloba múltiplos habitats, tais como praias, manguezais, costões rochosos, e uma planície de maré, e também fornece importantes serviços ecossistêmicos. Infelizmente, a baía está sujeita à conflitos sócio-ambientais complexos que contrastam demandas econômicas, sociais e ambientais (i.e. a expansão das atividades do porto vizinho vs. a pesca artesanal de pequena escala e a proteção da biodiversidade). O presente estudo apresenta um levantamento das espécies bentônicas que ocorrem nos diferentes habitats da Baía do Araçá, incluindo dados obtidos durante o projeto BIOTA/Araçá e de investigações realizadas anteriormente na área. As espécies bentônicas desempenham um papel importante no ambiente marinho, e estudar a diversidade desses organismos que vivem associados ao fundo é indispensável para compreender o funcionamento do meio ambiente. A macrofauna, meiofauna, e microorganismos associados aos fundos consolidado e inconsolidado foram listados, e informações adicionais foram fornecidas para cada espécie, tais como a distribuição geográfica e nos habitats. O checklist inclui 826 espécies, quase 70% registradas durante o projeto BIOTA/Araçá. Os taxa mais especiosos foram os anelídeos (225 spp.), moluscos (194 spp.), e crustáceos (177 spp.). Entre as espécies bentônicas listadas, sete são endêmicas da Baía do Araçá, 14 são consideradas ameaçadas de extinção, e sete são exploradas economicamente. A baía é a localidade tipo de vários taxa, e 11 novas espécies bentônicas foram descritas com base em espécimes amostrados durante o projeto. Este projeto mostra a importância da Baía do Araçá como um ambiente de riqueza biológica única e demonstra a necessidade de esforços para a sua conservação considerando as atuais ameaças.

Abstract Increasing habitat modification and species loss demand consistent efforts to describe and understand biodiversity patterns. The BIOTA/FAPESP Program was created in this context and it has been a successful initiative to promote studies on biodiversity and conservation in Brazil. The BIOTA/Araçá is an interdisciplinary project that provided a detailed evaluation of the biodiversity of Araçá Bay, a coastal seascape located on the North coast of the state of São Paulo, Southeast Brazil. The bay encompasses multiple habitats, such as beaches, mangroves, rocky shores, and a tidal flat, and provides important ecosystem services. Unfortunately, the bay is the subject of complex social-environmental conflicts that oppose economic, social, and environmental demands (i.e., the expansion of neighboring harbor activities vs. small-scale artisanal fisheries and protection of biodiversity). The present study presents a survey of the benthic species occurring in the different habitats of Araçá Bay, including data obtained during the BIOTA/Araçá project and previous assessments of the area. The benthic species play an important role in marine environments and studying the diversity of these organisms that live associated with the bottom is indispensable for comprehending the environment’s functioning. The macrofauna, meiofauna, and microorganisms associated with soft and hard bottom were listed, and additional information, such as the habitat and geographical distribution, were provided for each species. The checklist includes 826 species, almost 70% recorded during the BIOTA/Araçá project. The most speciose taxa were the annelids (225 spp.), mollusks (194 spp.), and crustaceans (177 spp.). Seven benthic species are endemic to Araçá Bay, 14 are considered threatened, and seven are economically exploited. Furthermore, the bay is the type locality of many taxa, and 11 new benthic species were described based on specimens sampled during the project. This project shows the importance of Araçá Bay as a unique biologically rich environment and highlights the need for conservation efforts in light of the current threats. patterns BIOTAFAPESP BIOTA FAPESP Brazil BIOTAAraçá Paulo beaches mangroves shores flat services Unfortunately socialenvironmental social economic i.e., ie i e (i.e. vs smallscale small scale biodiversity. . biodiversity) area s functioning macrofauna meiofauna listed information distribution 82 70 225 (22 spp., spp spp. , spp.) 194 (19 177 (17 spp.. 1 threatened exploited Furthermore threats i.e. (i.e 8 7 22 (2 19 (1 17 i.e 2 (

Abstract The article is an ethnographic exercise of fishing for blue land crab ( Cardisoma ganhumi ) in the mangroves of Baía de Todos os Santos. Taking as a reference the ways of living and inhabiting this crustacean and the gaiamunzeiros that capture them as a fishing activity, it aims to describe the effects of neoextractivism in the fishing landscapes of the region. The intention is, on the one hand, to show practices, habitability and landscapes associated with blue land crab fishing and, on the other hand, to offer a description of conflicts and impacts arising from agropastoral and oil infrastructures in their territories and ways of life. Thus, the article also aims to contribute to the public debate on the regulatory framework for blue land crab fisheries, reinforcing the importance of the participation of gaiamunzeiros and quilombola artisanal fishermen in decision-making on the preservation of the species and protection of their living environments.

Resumen: En | Texto: En | PDF: En

Abstract The Fundão dam failure in the Rio Doce basin in 2015 triggered a significant socioecological regime shift. In this study, changes and strategies employed by small-scale fisheries (SSFs) in the wake of dam failure were analyzed. From 2021 to 2022, 441 semi-structured interviews were conducted with fishers in Espírito Santo municipalities, using the snowball method to sample 20% of total fishers. The interviews focused on socioeconomic aspects and post-disaster changes. Responses were statistically analyzed according to data type (chi-square test, ANOVA, or Kruskal–Wallis’s test). Overall, 96.35% of surveyed participants were impacted by the dam failure. The strategies adopted after the disaster characterized three groups: the first abandoned the fishery, the second made adaptations in their fisheries, and the third did not make any changes. In this context, we highlighted two aspects for study: (1) understanding the characteristics of the most affected groups and (2) understanding the main adaptations found. The first aspect mainly involved those farther from the coastal zone, including a higher proportion of women and older and more experienced individuals who currently have a lower mean income and greater economic dependence on monetary indemnities. The second aspect involved those who managed to make adaptations, largely aimed at maintaining fishing activities, often by changing the target species and/or fishing area. All groups identified environmental contamination as the main current challenge. This study contributes to the deepening of knowledge about local impacts and recovery strategies following human-made disasters. Moreover, understanding the experiences of groups affected to varying degrees, each with distinct implications and structural differences, can facilitate the development of collective strategies for more effective coping with the challenges faced by SSFs. This case presents potential for improvement by adopting more participatory frameworks aimed at implementing mitigation and recovery measures. 201 shift smallscale small scale SSFs (SSFs 202 2022 44 semistructured semi structured municipalities 20 postdisaster post chisquare chi square test ANOVA Kruskal–Walliss KruskalWalliss Kruskal–Wallis s Kruskal Wallis test. . test) Overall 9635 96 35 96.35 fishery context 1 (1 2 (2 found zone indemnities activities andor area challenge humanmade human disasters Moreover degrees differences measures 4 Walliss KruskalWallis 963 9 3 96.3 ( 96.

Resumen: En | Texto: En | PDF: En

Abstract Human-wildlife conflicts pose significant challenges, requiring nuanced solutions rooted in ecological understanding and community engagement. In this sense, this opinion essay explores the first documented South American conflict scenario between Neotropic cormorants ( Nannopterum brasilianum ) and artisanal fisheries, located on Laguna Estuarine System, southern Brazil. Local reports converge on the information that, after 2015, Neotropic cormorants began to establish a reproductive colony on a non-breeders dormitory located at Noca Lagoon, near the estuary mouth. The colony’s consistent presence over the years and intense feeding activity, along with possible recruitment of cormorants, may lead to the perspective of increased population and nuances among fishermen. These concerns include vegetation suppression dealt by guano deposition, food competition, property damage, and fishery resources depletion. Despite no evidence of cormorant population increase and due the fact that fishing is an important regional activity, there was a response from local lawmakers to address this issue (Municipal Ordinary Law number 2.154/2020). The law imposes the harmful status to the native bird species and permit measures to “clean” harmful populations from properties. In addition, this law lacks control guidelines to cormorant populations, threating the local biodiversity and exacerbating the emerging human-wildlife conflict. To address these challenges, holistic and interdisciplinary approaches that understand cormorant behaviors and its interaction with fisheries activity are needed. From the knowledge bridge built from lawmakers, stakeholders, scientists, and fishermen, it is possible to foster dialogue and adopt a conceptual framework to mitigate conflict outputs and promote harmonious coexistence between wildlife and human activities.

Resumen: En | Texto: En | PDF: En

Abstract Despite their worldwide distribution, the occurrence of Lamnidae species in tropical zones remain poorly understood. In the Equatorial Southwestern Atlantic, the Shortfin Mako, Isurus oxyrinchus , has been captured in commercial fisheries, whereas the White Shark, Carcharodon carcharias , is only rarely recorded. This study aimed to characterize lamnid records for the Equatorial Southwestern Atlantic, as well as to apply molecular markers to identify a lamnid carcass from the only area in the region where these two species are known to overlap (off Ceará State, Northeastern Brazil). The landed carcass, although sold in the market as a White Shark, in fact was a Shortfin Mako, I. oxyrinchus , with a total of 99.6% and 100% match to its ND2 and D-loop mitochondrial DNA sequences, respectively. Despite the existence of a record of landings of elasmobranchs by artisanal and commercial fisheries from Ceará, lamnid landings in this region are still rare and comprise only four records for I. oxyrinchus , including juvenile specimens. As for the White Shark, Ceará State remains the only region in the Equatorial Southwestern Atlantic to hold records (three) of C. carcharias (all of them adults). Oceanographic conditions in this region may contribute to the occasional presence of large lamnid specimens. Moreover, fishers seem to support the presence of both lamnid species in the region. distribution understood Mako Shark recorded off Brazil. Brazil .

Resumo Actualmente, o pescado fresco marítimo assume um papel muito particular como marcador identitário no contexto dos sistemas alimentares dos núcleos piscatórios. Dada a relação, continuamente reiterada pelo discurso público, entre os benefícios do seu consumo e o paradigma da frescura, encontramos aqui uma paradoxal intersecção com o renovado movimento de redescoberta de Portugal como nação oceânica. Numa perspetiva holística, ecológica e cultural propomos aqui revelar alguns momentos da transfiguração do tão publicitado “melhor peixe do mundo” ao longo de um intrincado percurso, desde que é capturado no mar até à sua apresentação como produto artesanal de origem local. Esse amplamente reproduzido passe de magia: “do mar, diretamente para a sua mesa!”

Abstract Nowadays fresh sea fish plays a very particular role as an identity marker in the context of the food systems of fishing communities. Given the relationship, continually reiterated by public discourse, between the benefits of its consumption and the paradigm of freshness, we find here a paradoxical intersection with the renewed movement to rediscover Portugal as an oceanic nation. From a holistic, ecological and cultural perspective, we propose here to reveal some moments of the transfiguration of the much-publicized “best fish in the world” along an intricate pathway, from its capture at sea to its presentation as an artisanal product of local origin. That widely reproduced magic motto: “From the sea, straight to your table!”

RESUMEN Los mares y aguas continentales han sido espacios de luchas sociales históricamente invisibilizadas. Este artículo ofrece un análisis interdisciplinario de todas las decisiones de la Corte Constitucional colombiana relacionadas con violaciones de derechos humanos en territorios pesqueros artesanales. Por medio del enfoque basado en derechos humanos estudiamos 79 sentencias y construimos una base de datos digital llamada Justicia en Territorios Pesqueros. Identificamos y analizamos los derechos reivindicados (reclamados) y tutelados (protegidos) con mayor frecuencia. En su mayoría, las decisiones de la Corte indican que el sector de la pesca artesanal no es tenido en cuenta en la aprobación de proyectos de desarrollo. Concluimos que el Estado colombiano privilegia los intereses de los sectores económicos industriales en detrimento de los derechos de las poblaciones pesqueras.

ABSTRACT The seas and inland waters have historically been spaces of the invisibleness of social struggles. This article offers an interdisciplinary analysis of the Colombian Constitutional Court decisions related to human rights violations in artisanal fisheries territories. We used a human rights-based approach to study 79 court proceedings and built a digital database called Justice in Fishing Territories (Justicia en Territorios Pesqueros). We identified and analyzed the most frequently claimed and protected rights. Most of the Court proceedings are centered on participation processes, indicating that artisanal fisheries sector actors are not being considered in the approval of development projects. We conclude that the Colombian State privileges the interests of the industrial economic sector to the detriment of the rights of the fishing populations.

RESUMO Os mares e as águas continentais têm sido espaços de lutas sociais historicamente invisibilizadas. Este artigo oferece uma análise interdisciplinar de todas as decisões do Tribunal Constitucional da Colômbia relacionadas com violações de direitos humanos em territórios de pesca artesanal. Por meio da abordagem baseada em direitos humanos, estudamos 79 sentenças e construímos um banco de dados digital denominado Justiça nos Territórios Pesqueiros (Justicia en Territorios Pesqueros). Identificamos e analisamos os direitos reivindicados e protegidos com maior frequência. Em sua maioria, as decisões do Tribunal indicam que o setor da pesca artesanal não é levado em consideração na aprovação de projetos de desenvolvimento. Concluímos que o Estado colombiano favorece os interesses dos setores econômicos industriais em detrimento dos direitos das populações pesqueiras.

Resumen. El pez luna peruano, Selene peruviana, es un importante recurso desembarcado en las principales caletas pesqueras del Ecuador. A nivel local, existe poca información sobre la biología de esta especie, lo cual dificulta el desarrollo de planes de manejo. El presente estudio evalúa aspectos reproductivos de S. peruviana como la talla de madurez sexual y el ciclo reproductivo. Se obtuvieron muestras de capturas artesanales e industriales desde enero de 2017 hasta diciembre de 2018. Las características morfométricas, el sexo y la etapa de madurez de 886 especímenes fueron registrados y se estimó el índice gonadosomático (IGS), el índice hepatosomático (IHS) y el factor de condición relativo (Kn). La relación talla-peso y la talla de madurez sexual (L50) se evaluaron mediante la ecuación de alometría y análisis multimodelos, respectivamente. La talla media de captura (longitud total, LT) fue de 23.62 cm para los machos y 22.97 cm para las hembras. Se obtuvo una proporción de sexos (M:H) de 0.70:1.00 (χ2 = 26.28, P < 0.05). El factor alométrico de la relación longitud-peso para sexos combinados (b) fue 2.63 (t = 12.16, P < 0.05) y el coeficiente de determinación (r 2) fue 0.89, lo que sugiere una relación alométrica negativa. La L50 (LT) se estimó en 22.61, 23.86 y 23.27 cm para machos, hembras y sexos combinados, respectivamente. Los valores mensuales de IGS, IHS y Kn mostraron diferencias significativas (K-W, P < 0.05) entre los meses de estudio. Los valores máximos de IGS se observaron durante febrero y marzo, siendo el periodo de mayor actividad reproductiva. Los índices de IHS y Kn mostraron tendencias similares. La talla de madurez sexual fue similar a la talla media de captura, lo que podría indicar que S. peruviana se encuentra en el límite de su talla óptima de captura.

Abstract. The Peruvian moonfish (Selene peruviana) is an important fisheries resource that is landed in the main fishing harbors of Ecuador. At the local level, little information is available regarding the biology of this species, which hinders the development of management plans. The present study evaluates the reproductive characteristics of S. peruviana such as the size at sexual maturity and reproductive cycle. Specimens were obtained from artisanal and industrial catches from January 2017 to December 2018. The morphometric characteristics, sex, and maturity stage of 886 specimens were determined, and the gonadosomatic index (GSI), hepatosomatic index (HSI), and relative condition factor (Kn) were estimated. The length-weight relationship and length at sexual maturity (L50) were evaluated with an allometry equation and multi-model analyses, respectively. The mean capture size (total length, TL) was 23.62 cm for males and 22.97 cm for females. A sex ratio (M:F) of 0.70:1.00 (χ 2 = 26.28, P < 0.05) was obtained. The allometric factor of the length-weight relationship for both sexes (b) was 2.63 (t = 12.16, P < 0.05), and the coefficient of determination (r 2) was 0.89, which suggests that negative allometric growth was present. The L50 (TL) was estimated to be 22.61, 23.86, and 23.27 cm for males, females, and sexes combined, respectively. The monthly GSI, HSI, and Kn values were significantly different (K-W, P < 0.05) among study months. The maximum GSI values were observed in February and March, which constituted the period of highest reproductive activity. The HSI and Kn values exhibited similar trends. The size at sexual maturity was similar to the average catch size, which could indicate that S. peruviana is currently at the limit of its optimal catch size.

RESUMEN Los embalses Porce II y Porce III ubicados al nordeste del departamento de Antioquia presentan baja calidad del agua debido al ingreso de contaminantes químicos y biológicos provenientes de las descargas de aguas residuales de origen doméstico e industrial de diez municipios que conforman el Valle de Aburrá. En los embalses se ha reportado el desarrollo de pesquería artesanal con bajos estándares de inocuidad para su autoconsumo y comercialización. La seguridad alimentaria es fundamental para el aseguramiento de la salud pública, la normatividad colombiana para el consumo de productos pesqueros se enfoca en la prevención de riesgos y advierten oportunamente un manejo inadecuado y/o contaminación del producto pesquero (NTC1443:2016 y Resolución:776/2008, modificada por la Resolución:122/2012). En este proyecto se buscó determinar la calidad microbiológica bacteriana del músculo de Oreochromis niloticus y Coptodon rendalli proveniente de los embalses Porce II y Porce III a partir del análisis de indicadores de coliformes totales, Escherichia coli termotolerante, Staphylococcus aureus y Salmonella spp. usando microbiología convencional. En ocho muestreos entre marzo de 2018 y octubre de 2019, se compraron a pescadores locales 480 ejemplares, a los cuáles se les determinó la longitud total, longitud estándar y peso de cada pez y se analizaron los indicadores microbiológicos siguiendo las normativas colombianas (NTC4458, NTC4779, NTC4574). Bajo estos criterios, más del 80% de las muestras demostraron no conformidad ya que sobrepasaron los límites permitidos en cuanto a carga microbiana, por lo tanto, se infiere riesgo para la salud de comunidades humanas y silvestres que se alimenten de estos peces contaminados.

ABSTRACT The Porce II and Porce III reservoirs are located northeastern of the department of Antioquia, have poor water quality due to the entry of chemical and biological contaminants from domestic and industrial wastewater discharge from ten municipalities that are part of the Aburrá Valley. Artisanal fisheries have been reported in the reservoirs with low safety standards for self-consumption and commercialization. Food safety is fundamental for the assurance of public health. Colombian regulations for the consumption of fishery products focus on risk prevention and warn of improper handling and/or contamination of the fishery product (NTC1443:2016 and Resolution:776/2008, modified by Resolution:122/2012). This project sought to determine the bacterial microbiological quality of Oreochromis niloticus and Coptodon rendalli muscle from Porce II and Porce III reservoirs by analyzing the indicators total coliforms, thermo-tolerant Escherichia coli, Staphylococcus aureus and Salmonella spp. in eight samplings between March 2018 and October 2019, 480 specimens were purchased from local fishermen. Total length, standard length, and weight of each fish was determined, and microbiological indicators were analyzed following Colombian standards (NTC4458, NTC4779, NTC4574). Under these criteria, more than 80% of the samples showed non-compliance because they exceeded the permitted limits for microbial load. The health risk for human and wild communities that feed on these contaminated fish is inferred.
