Resumen. Los tambores y roncadores (Sciaenidae) son parte importante de la composición específica de las capturas costeras en el Golfo de California, México. Dentro de este grupo de especies, la curvina rayada (Cynoscion reticulatus) destaca por su alto potencial pesquero, gran demanda y debido a que ha incrementado su valor de mercado. La curvina rayada ha estado bajo constante presión pesquera durante los últimos 20 años. Sin embargo, se necesita contar con información biológica actual o puntos de referencia que permitan establecer medidas de manejo pesquero. Por tanto, el objetivo del presente estudio fue estimar la longitud estándar media de madurez sexual (LE 50 ) utilizando varios modelos para sugerir una talla mínima de captura (TMC) de C. reticulatus en la costa sur de Sinaloa. Para esto, se realizaron muestreos mensuales en las descargas de la flota costera desde diciembre de 2020 hasta diciembre de 2021 en la costa sur de Sinaloa. La LE 50 se evaluó con base en 3 modelos candidatos (Gompertz, Lysack y White) a través de un enfoque binomial. Los intervalos de confianza para la LE 50 se estimaron utilizando perfiles y contornos de verosimilitud, y se utilizó el criterio de información de Akaike (CIA) para seleccionar el mejor modelo. Se examinaron un total de 284 individuos, de los cuales 131 se utilizaron en el análisis. El modelo de White fue el más adecuado; sin embargo, con base en los pesos de CIA, los 3 modelos mostraron un rendimiento similar, por lo que la LE50 (24.48 cm; IC 95% 12.9-36.0 cm) se estimó como el promedio de estos. Por último, como medida de manejo, proponemos una TMC bajo un enfoque precautorio de 36 cm LE para C. reticulatus en la costa sur de Sinaloa.

Abstract. Drums and croakers (Sciaenidae) are important to the species composition of coastal catches in the Gulf of California, Mexico. Among these species, the striped corvina (Cynoscion reticulatus) stands out because of its high fishery potential, high demand, and increased market value. The striped croaker has been under constant fishing pressure over the past 20 years. Still, there needs to be current biological information or reference points to allow the establishment of management measures for fisheries. The objective of the present study was to estimate the mean standard length at sexual maturity (SL 50 ) of females using various models and to suggest a minimum catch size (MCS) for C. reticulatus off the southern coast of Sinaloa. Monthly samplings of coastal fishery landings were done from December 2020 to December 2021 on the south coast of Sinaloa. The SL 50 was evaluated based on 3 candidate models (Gompertz, Lysack, and White) through a binomial approach. Confidence intervals for SL 50 were estimated using likelihood profiles and contours, and Akaike’s information criterion (AIC) was used to select the best model. A total of 284 individuals were examined, of which 131 were used in calculations. White’s model was the most adequate; however, based on AIC weights, all 3 models performed similarly, and SL 50 (24.48 cm; C.I. 95% 12.9-70 36.0 cm) was estimated as their average. As a management measure, we propose a precautionary MCS of 36 cm SL for C. reticulatus off southern Sinaloa.

Abstract Introduction: Semaprochilodus laticeps is a freshwater fish species native to the Orinoco Basin that is exploited in Colombia at two different stages of its life cycle: fry (for the ornamental trade) and adults (for the consumer market). This double exploitation of juveniles and adults raises concerns about the population stability of the species. Objective: To evaluate the sustainability of the exploitation of the species in these two life stages. Methods: 1 277 specimens of S. laticeps were sampled between June and December 2017. Population parameters were estimated from length-frequency data using ELEFAN 1 routine of the FISAT II package. Length at first maturity (Lm) and length at maximum yield (Lopt) were determined using the Froese and Binohlan equations. Virtual population analysis was performed based on Jones length cohort analysis. Results: Population parameters were as follows: K = 0.75, L∞ = 53.1 cm LE, Z = 2.92 yr-1, M = 1.24 yr-1 and F = 1.68. Lm was estimated to be 29.6 cm SL and Lopt at 33.4 cm SL. Of note, 96.3 % of the fish caught in the consumer fishery exceeded Lm and 80 % exceeded Lopt. The results of the virtual population analysis suggested that a very low proportion (0.85 %) of the population was caught as fry, possibly due to natural mortality. Conclusions: Based on the results, as no indicators of overexploitation were identified, it is recommended to continue with the dual use of S. laticeps. It is recommended to maintain the existing conservation measures, such as the closed season during the reproductive period, to ensure sustainable fishery exploitation. The results obtained can serve as a reference to analyze the situation of other species currently fished for both the ornamental (fry) and food (adult) markets.

Resumen Introducción: Semaprochilodus laticeps es una especie de pez de agua dulce originaria de la cuenca del Orinoco, explotada en Colombia en dos etapas distintas de su ciclo de vida: alevín (para el comercio ornamental) y adulto (para el mercado de consumo). Esta doble explotación de alevines y adultos genera preocupación sobre la estabilidad poblacional de la especie. Objetivo: Evaluar la sostenibilidad de la explotación de la especie en estas dos etapas de vida. Método: Entre junio y diciembre de 2017 se muestrearon 1 277 ejemplares de S. laticeps. Los parámetros poblacionales se estimaron utilizando datos de frecuencia de tallas con la rutina ELEFAN 1 del paquete FISAT II. La longitud de primera madurez (Lm) y la de máximo rendimiento (Lopt) se determinaron mediante ecuaciones de Froese y Binohlan. El análisis de la población virtual se realizó basándose en el análisis de cohorte de longitud de Jones. Resultados: Los parámetros poblacionales fueron los siguientes: K = 0.75, L∞ = 53.1 cm LE, Z = 2.92 año-1, M = 1.24 año-1 y F = 1.68. Lm se estimó en 29.6 cm SL y Lopt en 33.4 cm SL. En particular, el 96.3 % del pescado capturado en la pesquería de consumo superó Lm y el 80 % superó Lopt. El análisis de la población virtual sugirió que una fracción muy baja (0.85 %) de la población fue capturada como alevines, posiblemente atribuible a la mortalidad natural. Conclusiones: Con base en los hallazgos, al no identificarse indicadores de sobreexplotación, se recomienda continuar con el doble uso de S. laticeps. Se recomienda mantener las medidas de protección existentes, así como una veda durante el período reproductivo, para garantizar una explotación pesquera sostenible. Los resultados obtenidos pueden servir como referencia para analizar la situación de otras especies actualmente capturadas para el mercado tanto ornamental como de consumo.

Abstract Catch and fishing effort data are generally available, hence surplus production models are commonly used to conduct assessments. However, hyperstability resulting from spawning aggregations (SA) pose challenges to determine status and inform management of many fisheries resources. Using data from 1991 to 2019, we develop a method to study hyperstable fished stocks relaxing the assumption of constant catchability, hence direct dependence of catch-per-unit-effort and biomass. Information criterion was used to choose the best model including a Cobb-Douglas function for gulf corvina (Cynoscion othonopterus), a sciaenid fish endemic to the gulf of California, managed through annual quotas. Bionomic stock-reduction models were fit using catch, effort, published natural mortality, virgin biomass, and economic structure. Models were solved using maximum likelihood and the best model chosen with Akaike information criterion. Current fishing effort is beyond bionomic optimum. This deserves a precautionary approach to protect this endemic species and sustain the fishery.

Resumen Generalmente se disponen de datos de captura y esfuerzo para evaluar stocks usando modelos de producción excedente. Sin embargo, la hiperestabilidad resultante de agregaciones de desove (AD) genera retos en muchos recursos pesqueros; entonces se recomienda usar funciones de producción no lineal. Utilizando datos de 1991 a 2019, desarrollamos un método para evaluar pesquerías de recursos hiperestables, relajando el supuesto de capturabilidad constante y dependencia directa de captura-por-unidad-de-esfuerzo y biomasa. Usamos criterios de información para determinar el mejor modelo usando una función Cobb-Douglas. Ejemplificamos con la pesquería de corvina "golfina" (Cynoscion othonopterus), un pez endémico al golfo de California con un sistema de cuotas anuales. Los modelos bionómicos se ajustaron utilizando captura y esfuerzo anuales, tasas de mortalidad natural, biomasa virgen y estructura económica. Ajustando por máxima verosimilitud, el mejor modelo se eligió con el criterio de Akaike. El esfuerzo de pesca actual sobrepasa el óptimo bionómico. Esto implica adoptar enfoques precautorios para proteger esta especie endémica y sostener la pesquería.

Research that directs the way stakeholders act and how they collaborate is essential when addressing complex environmental challenges in the field of sustainability science. For example, researchers attempting to manage Prosopis invasions through biological control in South Africa have historically faced challenges from stakeholders. In this study we illustrate the importance of stakeholder engagement and social learning by outlining the collaborative efforts of various stakeholders to promote effective, integrative and sustainable management of Prosopis invasions in the Northern Cape, South Africa. Through a community of practice approach, stakeholders worked together over the past half-decade in an attempt to develop a National Strategy for Prosopis management and improve its control. This strategy aimed not only to emphasise the need for integration of biomass use (aimed at offsetting the costs of mechanical clearing and necessary herbicide use) but also to underscore the significance of biocontrol alongside other management approaches. Stakeholders also identified that adequate farm-scale planning is necessary to provide a sense of purpose and assist in monitoring of progress. We worked alongside land managers and experts to develop such plans. The engagement of local champions played a crucial role in facilitating collaboration and learning among stakeholders, emphasising the significance of inclusive approaches in addressing complex sustainability challenges. In addition, we gained an understanding of how to develop the community of practice to enhance collaboration that ensures the implementation of plans to better manage Prosopis. Our findings underscore the necessity of meaningful stakeholder engagement and collaboration in effective invasive species management. By promoting understanding and involvement of diverse stakeholders, initiatives can have a greater impact in addressing broader sustainability issues. SIGNIFICANCE: Our findings highlight the fundamental role of stakeholder collaboration in addressing environmental challenges (e.g. biological invasions), promoting sustainability and fostering social learning. Collaboration facilitates exchange of knowledge, promotes social learning and allows stakeholders to make informed decisions when addressing sustainability issues. Collaborative approaches promote the effectiveness of a community of practice in managing Prosopis invasions in South Africa. Local champions played a pivotal role in facilitating collaboration, bridging communication gaps and promoting inclusive approaches. Sustained stakeholder engagement, transdisciplinary collaborations, effective biological control and market development for biomass products will be essential to improve the sustainable management Prosopis.

ABSTRACT This study examines the distributional behavior of the anchovy (Engraulis ringens) in the area between latitudes 06° 00´ and 11° 59´ S during four research activities conducted by Imarpe from February to June 2022. This area was initially restricted in the first fishing season due to the high presence of juvenile specimens. The purpose was to observe the redistribution of anchovy to propose management measures for fisheries sustainability. During activities 1 and 2, a high concentration and abundance of anchovy were observed, while in activities 3 and 4, the anchovy dispersed, migrating towards areas away from the coast. This variability in distribution affected energetic and morphometric descriptors, with high values during high concentrations and lower values when it was dispersed. In the coastal strip of the 55.56 km (30 nautical miles), there was an overlap of juveniles and adults, with normal somatic growth between activities 1 and 4. The main modes in each activity were 8.5, 10, 9.5, and 10.5 cm, respectively. Biomass varied from 6.86 million tons in activity 1 to 3.00 million tons in activity 4, influenced by oceanographic conditions and chlorophyll-a productivity.

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.

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. A commercial fishery for the smooth hammerhead shark (Sphyrna zygaena) exists in the waters off northern Peru. Although international and domestic norms regulate this species, adult specimens are becoming rare. Monthly visits to four ports in the La Libertad region were made to measure S. zygaena landings and understand the present state of the fishery. We found that 92% of the specimens landed were juveniles or younger and that 10% of the original biomass remains in the fishery. This highlights that stricter regulations such as protecting breeding areas, establishing a legal catch length, and limiting the catch volume and fishing season are urgently needed to maintain a sustainable fishery.

Resumo Muitos países enfrentaram crises na pandemia de coronavírus em todo o mundo. Por meio do surto dessa doença no Irã, planos preventivos foram implementados para quebrar a cadeia de infecção da doença. Essas medidas no setor econômico afetaram a oferta, a produção e a demanda e, em certa medida, levaram ao fechamento parcial ou total de alguns negócios e serviços. Nesse contexto, parece que medidas de infraestrutura inovadoras e com “capacidade de inovação” podem ser uma estratégia para moderar e otimizar a situação nesta crise. Este estudo tenta desenhar conceitos do modelo de capacidade de inovação das empresas de pesca no contexto da crise da pandemia de COVID-19. Após a coleta dos dados, eles foram analisados por meio dos softwares SPSS e PLS SMART e realizados em duas partes: estatística descritiva e estatística analítica ou inferencial. Um novo modelo de pesquisa é apresentado para examinar o impacto de fatores como gestão da inovação, capital social, cultural, humano e organizacional, estratégias de crise, ações governamentais em situações de crise e estratégias de marketing em situações de crise, bem como reconhecimento e aplicação de vantagens de marketing em situações de crise, que oferece uma reanálise da capacidade de inovação. De acordo com os resultados, entre as variáveis que desempenharam um papel significativo no nível de capacidade de inovação em condições epidêmicas, a gestão da inovação (p > 0,000; β = 0,593) e o reconhecimento e aplicação de vantagens de marketing (p > 0,049; β = 0,209) foram as variáveis independentes mais significativas que afetaram a capacidade de inovação, o que explicou suas variações.

Abstract Many countries have encountered coronavirus pandemic crisis around the world. Through the outbreak of this disease in Iran, preventive plans have been implemented to break the chain of the disease infection. These measures in the economic sector have affected supply, production and demand, and to some extent have led to the partial or complete closure of some businesses and occupations. In the context, it seems that innovative an “innovation capacity” infrastructure measures and turning to innovation in this crisis can be a strategy to moderate and optimize the situation. This study tries to design concepts of the fisheries firms’ innovation capacity model in the context of the COVID-19 pandemic crisis. After collecting data, they were analyzed using SPSS and PLS SMART software, which were performed in two parts: descriptive statistics and analytical or inferential statistics. A novel research model is presented to examine the impact of factors such as innovation management, social, cultural, human and organizational capital, crisis strategies, government actions in crisis situations, and marketing strategies in crisis situations, as well as, recognition and application of marketing advantages in crisis situations, which offers a re-analysis of innovation capacity. According to the results, among the variables played a significant role on the level of innovation capacity in epidemic conditions, innovation management (p> 0.000; β = 0.593), and recognition and application of marketing advantages (p> 0.049; β = 0.209) were the most significant, independent variables affecting the innovation capacity, which explained its variations.

Abstract The objective of this study was to spatialize sport fishing operations and assess the frequency of the use of the fishing areas in the state of Amazonas by combining the Geographic Information System (GIS) approach and information available in the documents sent to the Instituto de Proteção Ambiental do Amazonas (IPAAM). Information on sport fishing tourism operations was gathered from the IPAAM database and fishing licenses (FLs). Data analysis was conducted utilizing descriptive analysis, and the spatialization of the locations was performed using Q-GIS software. From 2002 to August 2021, 163 requests for FLs were made. There was a decrease in the amount of first time FL requests, with a peak in 2018 and 2019, N=17 and N=18, respectively. The activity is conducted in 24 municipalities, with Barcelos (31.36%) and Presidente Figueiredo (17.75%) being the most popular. At the sub-basin level, sport fishing is notably present in the Negro, Amazonas, Aripuanã, Madeira, Purus and Solimões River basins. Overall, 26.38% of operations take place in conservation areas, specifically in sustainable development reserves (SDRs). Barcelos recorded the largest number of rivers used, with 15 rivers.

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.

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.

Resumen La dominación colonial establecida a partir del siglo XV sigue siendo un elemento fundacional de la racionalidad moderna. En la dimensión epistemológica, la colonialidad del conocimiento institucionaliza el papel de la ciencia eurocéntrica en la discriminación del conocimiento entre falso y verdadero. La descolonización como proyecto inconcluso, asociado a modelos autoritarios de gestión pesquera, ha forjado contextos de injusticia ambiental. Entre estos, destacamos el proceso de desterritorialización de las comunidades pesqueras artesanales, reconfiguradas por el Estado como zonas de sacrificio. Así, analizamos la imposición de la veda en Lagoa de Araruama-RJ, a partir de las narrativas de la comunidad pesquera artesanal de Praia do Siqueira, ubicada en sus márgenes.

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

Resumo A dominação colonial estabelecida a partir do século XV mantém-se como elemento fundante da racionalidade moderna ocidental, atuando de forma tão invisível quanto eficiente na produção de subalternidades. Na dimensão epistemológica, a colonialidade do saber institucionaliza o papel da ciência moderna eurocêntrica na discriminação de conhecimentos entre falsos e verdadeiros. A descolonização como projeto inacabado, associado a modelos de gestão pesqueira autoritários, tem forjado contextos de injustiça ambiental. Dentre estes, destacamos o processo de desterritorialização de comunidades pesqueiras artesanais, reconfiguradas pelo Estado como zonas de sacrifício. Como exemplo fático, analisamos a imposição do período de defeso na Lagoa de Araruama-RJ a partir das narrativas da comunidade pesqueira artesanal da Praia do Siqueira, localizada as suas margens.

Abstract Assessing the impacts caused by fisheries requires long-term data series and continuous landing monitoring, which are still scarce in several low and middle-income countries. Alternative approaches, such as fishers’ local ecological knowledge (LEK) have been employed to assess the history of marine resources and overcome the challenges of missing data. We documented temporal changes over the last 60 years in small-scale fisheries in Arraial do Cabo, Brazil. Interviews with 155 fishers revealed the capture of six shark species (one genus), all under extinction risk according to the global and the national Red Lists. Among these, Carcharhinus brevipinna, Carcharhinus plumbeus, and Isurus oxyrinchus are commercially important. While LEK suggests an increase in fishing efforts, with new fishing grounds emerging after 2006, the number of individuals caught has decreased over time. Historical shark exploitation has led to substantial declines in the catches of C. plumbeus and C. brevipinna, which have rare occurrences in the region. Although landing data are critical information for building local fisheries management plans and setting conservation strategies, monitoring in the region is discontinuous and should be prioritized by public policies. longterm long term middleincome middle income countries approaches (LEK 6 smallscale small scale Cabo Brazil 15 one genus, genus , genus) Lists these brevipinna important efforts 2006 time C strategies policies 1 200 20 2

Resumo Avaliar os impactos causados pela pesca requer dados de longo prazo e monitoramento contínuo das capturas, os quais ainda são escassos em vários países de baixa e média renda. Abordagens alternativas, como o conhecimento ecológico local dos pescadores (CEL), têm sido utilizadas para avaliar a história dos recursos marinhos e superar os desafios da ausência de dados. Documentamos mudanças temporais ao longo dos últimos 60 anos na pesca artesanal em Arraial do Cabo, Brasil. Entrevistas com 155 pescadores revelaram a captura de seis espécies de tubarões e um gênero, todas em risco de extinção de acordo com as Listas Vermelhas global e nacional. Entre essas espécies, Carcharhinus brevipinna, Carcharhinus plumbeus e Isurus oxyrinchus são comercialmente importantes. Embora o CEL tenha revelado um aumento nos esforços de pesca, com novos locais de pesca surgindo após 2006, o número de indivíduos capturados diminuiu ao longo do tempo. A exploração histórica de tubarões levou a declínios substanciais nas capturas de C. plumbeus e C. brevipinna, os quais possuem ocorrências raras na região. Embora os dados de desembarque sejam informações críticas para elaborar planos de gestão pesqueira local e estabelecer estratégias de conservação, o monitoramento na região é descontínuo e deveria ser priorizado por políticas públicas. renda alternativas CEL, , (CEL) 6 Cabo Brasil 15 gênero nacional brevipinna importantes 2006 tempo C conservação públicas (CEL 1 200 20 2

ABSTRACT In this study, the length-weight relationships (LWRs) and length-length relationships (LLRs) of 16 marine fish species-important component of fishery production models-were estimated. The specimens were collected monthly from commercial gillnet fisheries from November 6, 2018 to October 30, 2019 in Vietnamese waters. In total, 7,426 individuals had their total length (TL), fork length (FL) and total body weight (W) measured. LWRs were calculated using the logarithmic transformation of the linear regression equation logW = loga + b*logTL, while LLRs were determined using a linear regression model: TL = a + b*FL. In addition, 95% confidence intervals (CIs) were estimated for the model parameters. The results showed that all regression parameters were highly significant (p < 0.001), with coefficients of determinations (R 2 ) > 0.9412 for all species. The a (intercept) values ranged from 0.0025 to 0.4, and the b (slope) values ranged from 2.53 to 3.28. TL and FL were highly correlated (p < 0.001 and R 2 > 0.9422 for all parameters), and a and b ranged from -9.12 to 15.85 and 0.87 to 1.45, respectively. The results provide the key morphology parameters, which are beneficial for fishery researchers and managers in stock assessment, administration and conservation. study lengthweight (LWRs lengthlength (LLRs 1 speciesimportant species important modelswere models 6 201 30 waters 7426 7 426 7,42 TL, , (TL) (FL W (W measured blogTL logTL b*logTL bFL b*FL addition 95 CIs (CIs p 0.001, 0001 0 001 0.001) 09412 9412 0.941 intercept (intercept 00025 0025 0.002 04 4 0.4 slope (slope 253 53 2.5 328 3 28 3.28 0.00 09422 9422 0.942 parameters) 9.12 912 9 12 -9.1 1585 15 85 15.8 087 87 0.8 145 45 1.45 respectively assessment conservation 20 742 42 7,4 (TL 000 00 0941 941 0.94 0002 002 0. 25 5 2. 32 3.2 0.0 0942 942 9.1 91 -9. 158 8 15. 08 14 1.4 74 7, 094 94 0.9 3. 9. -9 1. 09 -

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.

Abstract one of the leading causes of global biodiversity loss is the introduction of non-native species with high potential for invasion, and fish farms are largely responsible for introducing these species into continental aquatic ecosystems. To assess the possible impacts caused by the introduction of fish species from fishing grounds in natural areas in the Baixada Santista watershed (São Paulo, State, Brazil), the Aquatic Species Invasiveness Screening Kit (AS-ISK) was used. The study showed that escaped species, primarily caused by the water drainage system of fishing ground tanks and dispersion by birds, can cause significant damage to the conservation of native species. Therefore, it is imperative to establish management practices for cultivated species and frequently monitor the physical-chemical and microbiological parameters of water quality in ponds. African catfish (Clarias gariepinus), Nile Tilapia (Oreochromis niloticus), Carp (Cyprinus carpio) and Trahira (Hoplias malabaricus) showed a high risk of invasion. Conversely, Tambaqui (Colossoma macropomum) was classified as medium risk, highlighting the importance of this species for breeding in fish farming systems and recreational fishing activities conducted in fishing grounds. nonnative non invasion ecosystems São Paulo State Brazil, Brazil , Brazil) ASISK AS ISK (AS-ISK used birds Therefore physicalchemical physical chemical ponds Clarias gariepinus, gariepinus gariepinus) Oreochromis niloticus, niloticus niloticus) Cyprinus carpio Hoplias malabaricus Conversely Colossoma macropomum
