Metal-organic Framework Immobilized Enzyme and Its Application in Screening of Enzyme Inhibitors of Traditional Chinese Medicine：A Review / 中国实验方剂学杂志

Enzymes are widely used in chemical and pharmaceutical industries because of their advantages of high efficiency and specificity. However， the shortcomings of the free enzymes， such as poor stability and difficulty in recycling， limit their application. Therefore， the immobilization and application of enzymes have become one of the research hotspots. The selection of the immobilization carriers is a critical step in the process of enzyme immobilization. Metal-organic frameworks（MOFs）， a kind of porous materials， are formed by the coordination of metal ions or metal clusters with organic ligands. As an emerging immobilization carrier， its advantages such as high porosity， strong stability， and surface modifiability make it ideal for immobilized enzyme carriers. By immobilizing the free enzyme on MOFs， the above mentioned deficiencies of the free enzymes can be effectively solved， which greatly broaden the applicable condition. Ligand fishing is a method to find receptor-specific ligands from complex components， which has the advantages of high efficiency， simple sample pretreatment and high specificity. The MOF-enzyme complex formed by enzyme immobilization can act as a "fishing rod" for ligand fishing， which can screen out the targets from the complex system of components. The complex chemical composition and various active ingredients of traditional Chinese medicine（TCM） make the ligand fishing technology to play a big role in the screening of enzyme inhibitors from TCM. And the screened enzyme inhibitors are expected to be further developed into the lead compounds with good efficacy and low adverse effects， so the immobilized enzymes of MOFs have a wide application in the screening of active ingredients from TCM. Based on this， this paper summarized the methods of immobilized enzymes of MOFs in recent years， analyzed the characteristics， advantages and disadvantages of each method， and summarized the laws of preparation conditions and mechanisms. Meanwhile， the application and future development of immobilized enzymes of MOFs in the field of enzyme inhibitor screening from TCM were also summarized and prospected， with a view to providing a reference for the development of natural ingredients and the modernization of TCM.

Flotas de pesca extranjeras en el Pacífico costarricense y su traslape con áreas protegidas oceánicas, el ordenamiento pesquero y el Domo Térmico / Foreign fishing fleets in the Costa Rican Pacific and their overlap with oceanic protected areas, the fishing zoning, and the Thermal Dome

Introduction: Until today, the fishing effort by foreign fleets in the Costa Rican Pacific has not been analyzed. Objective: To determine the spatial distribution of the fishing effort of those fleets, variables that shape that distribution, and if they interact with management figures and highly fragile ecosystems. Methods: Using fishing effort data from 2012 to 2020, obtained from Global Fishing Watch, an Index of Fishing Effort (IEP) was calculated to apply geospatial and multivariate statistics, as well as multiple regression models. A grid with 55 905 cells of 0.10 degrees was used to apply Hot Spot Analysis, and another grid with 24 176 cell-year-month analysis units of 0.25 degrees was used to apply a Linear Regression Model. Results: The data reveals the fishing activity of international fleets associated with four types of fishing gear, and a wide coverage of a high IEP by two fleets throughout the nine years analyzed. The IEP is primarily associated with location and varies by month and year. There is also relative evidence that its influenced by the concentration of oxygen and nitrates. Conclusions: International fleets come into direct conflict with officially defined zones for national fleets and disrespect protected oceanic areas and a declared non-fishing zone to protect marine resources in the Costa Rican Pacific. Their activities in the Dome may affect a national yellowfin tuna fishery.

Introducción: Hasta hoy, no ha sido analizado el esfuerzo pesquero por parte de flotas extranjeras en el Pacífico de Costa Rica. Objetivo: Determinar la distribución espacial del esfuerzo pesquero de esas flotas, variables que moldean esa distribución, y si las mismas interactúan con figuras de manejo y ecosistemas altamente frágiles. Métodos: A partir de datos de esfuerzo pesquero de 2012 a 2020, obtenidos de Global Fishing Watch, fue calculado un Índice de Esfuerzo Pesquero (IEP) sobre el cual fue aplicada estadística geoespacial y multivariada, así como modelos de regresión múltiple. Fue utilizada una cuadrícula con 55 905 celdas de 0.10 grados, para aplicar Análisis de Puntos Calientes, y otra cuadrícula con 24 176 unidades de análisis celdas-año-mes de 0.25 grados, para aplicar un Modelo de Regresión Lineal. Resultados: Los datos revelan la actividad pesquera de las flotas internacionales asociadas a cuatro tipos de artes de pesca, así como una amplia cobertura de alto IEP por parte de dos flotas a lo largo de los nueve años analizados. El IEP se asocia principalmente con la ubicación y varía según el mes y el año. También hay evidencia relativa de que está influenciado por la concentración de oxígeno y nitratos. Conclusiones: Las flotas internacionales entran en conflicto directo con zonas oficialmente delimitadas para las flotas nacionales e irrespetan las áreas oceánicas protegidas y una zona no pesquera declarada para proteger los recursos marinos en el Pacífico costarricense. Sus actividades en el Domo pueden afectar la pesquería de atún aleta amarilla.

Association of sunlight exposure with visual impairment in an Indian fishing community

Purpose: Indian fishermen belong to a marginalized population and are continuously exposed to extreme occupational hazards and sunlight. A high prevalence of visual impairment (VI) is reported in the coastal fishing community. We aimed to investigate the association between VI and sunlight exposure measurement (SEM). Methods: In this cross?sectional observational study, 270 eyes of 135 participants were enrolled from a coastal fishing village. Participants underwent a comprehensive ophthalmic examination, which included best?corrected visual acuity (BCVA), and anterior and posterior segment examination. Ocular Surface Disease Index (OSDI) and SEM questionnaire were administered to estimate the level of dry eye and ultraviolet?B (UV?B) exposure, respectively. VI was defined as presenting visual acuity worse than 6/12 (logarithm of the minimum angle of resolution [logMAR] > 0.3). Results: The mean age and spherical equivalent were 50.56 ± 11.72 years (range: 18–80 years) and 0.36 ± 1.68 diopters (D) (range: ?7.0 to +3.0 D), respectively. Age, SEM, OSDI, fishing as an occupation, and cataract were significantly associated with higher odds of VI in univariate analysis. Refraction, gender, education level, smoking status, amblyopia, systematic, and other ocular diseases were not significantly associated with VI. In the multivariate analysis, age, SEM, and presence of cataract remained significantly associated with a higher risk for VI. The area under the receiver operating characteristic curve values for age and SEM scores demonstrate a fair index of discrimination for the detection of VI. Conclusion: SEM level is directly associated with a higher risk of VI among fishermen. The fishing community might benefit from regular eye examinations and awareness about the harmful effects of sunlight exposure and preventive measures.

Benefícios previdenciários de pescadores artesanais e marisqueiras em comunidade quilombola no Nordeste do Brasil / Social security benefits for small-scale fisherman in a quilombola community in northeastern Brazil

Resumo Introdução: a pesca artesanal e a mariscagem são consideradas atividades especiais, para fins de benefícios, no âmbito do Regime Geral de Previdência Social do Brasil. Objetivo: descrever o acesso aos benefícios previdenciários por uma população quilombola tradicional pesqueira no Nordeste do Brasil, cuja principal atividade ocupacional é a extração e beneficiamento de mariscos. Métodos: estudo transversal, descritivo, em uma comunidade da Ilha da Maré, em Salvador, Bahia, Brasil. Os dados foram coletados por meio de entrevistas, utilizando questionários padronizados. Resultados: participaram 213 pescadores artesanais e marisqueiras, 76,5% do sexo feminino. Dentre os participantes, 62,9% não recebem nenhum tipo de benefício previdenciário. Apesar de se submeter a uma jornada de trabalho exaustiva (90,9%), com exposição a substâncias químicas (83,9%), ruído (69,9%) e radiação solar (88,2%), a maioria não obtém rendimentos que garantam a subsistência familiar (79,6%). Conclusão: há um importante déficit no recebimento de benefícios previdenciários em uma população quilombola tradicional que atende aos critérios de segurados especiais. Sugere-se adequação da legislação, de forma que o acesso aos benefícios se torne mais justo para as comunidades tradicionais.

Abstract Introduction: artisanal fishing and shellfish gathering are considered special activities under the Brazilian general social security system for the purposes of social security benefits. Objective: to describe the access to social security benefits for a traditional fishing quilombola community in northeastern Brazil, whose main occupational activity is shellfish extraction and processing. Methods: a cross-sectional descriptive study conducted in a community from Ilha da Maré, Salvador, Bahia, Brazil. Results: 213 fishermen (76.5% female) participated in the study, of which 62.9% did not receive social benefits. Although most participants undergoing an exhausting working hours (90.9%), with exposure to chemicals (83.9%), noise (69.9%) and solar radiation (88.2%), the majority of them do not earn an income that guarantees their family's subsistence (79.6%). Conclusion: there is an important deficit in social security benefits access for a traditional quilombola population that meets the criteria for special insurance. Legislation must be adapted to ensure fairer access to social benefits for this population.

The Serra Spanish mackerel fishery (Scomberomorus brasiliensis – Teleostei) in Southern Brazil: the growing landings of a high trophic level resource / A pesca da cavala, Scomberomorus brasiliensis (Teleostei), no sul do Brasil: o aumento nos desembarques de um recurso de alto nível trófico

In fisheries, the phenomenon known as fishing down food webs is supposed to be a consequence of overfishing, which would be reflected in a reduction in the trophic level of landings. In such scenarios, the resilience of carnivorous, top predator species is particularly affected, making these resources the first to be depleted. The Serra Spanish mackerel, Scomberomorus brasiliensis, exemplifies a predator resource historically targeted by artisanal fisheries on the Brazilian coast. The present work analyzes landings in three periods within a 50-year timescale on the Parana coast, Southern Brazil, aiming to evaluate whether historical production has supposedly declined. Simultaneously, the diet was analyzed to confirm carnivorous habits and evaluate the trophic level in this region. Surprisingly, the results show that from the 1970's to 2019 Serra Spanish mackerel production grew relatively to other resources, as well as in individual values. The trophic level was calculated as 4.238, similar to other Scomberomorus species, consisting of a case where landings increase over time, despite the high trophic level and large body size of the resource. The results agree with a recent global assessment that has demystified a necessary correlation between high trophic level and overexploitation, but possible factors acting on the present findings are discussed.

Na pesca, o fenômeno fishing down food webs, ou 'pescando teias tróficas abaixo', expressa a redução do nível trófico na composição das capturas, e tem origem tradicionalmente atribuída à sobrepesca. Sob intenso extrativismo, a resiliência das espécies carnívoras, predadoras de topo, é particularmente afetada, sendo seus estoques os primeiros a entrarem em depleção. A cavala, ou serra, ou sororoca, Scomberomorus brasiliensis, é exemplo de recurso predador historicamente alvo da pesca artesanal, de pequena escala, na costa brasileira. O presente trabalho analisa os valores de desembarque do recurso em três períodos ao longo de 50 anos na costa paranaense, sul do Brasil, com objetivo de avaliar se sua produção tem efetivamente diminuído. Ainda, estuda-se a dieta da espécie na região, para confirmar seus hábitos carnívoros e avaliar o nível trófico na região. Os resultados mostram que, surpreendentemente, dos anos 1970 para 2019 a produção de S. brasiliensis tem aumentado em valores absolutos, bem como relativamente à de outros recursos, em que pese o nível trófico 4,238, similar a outras espécies do gênero. Constata-se que a pesca da cavala na região de estudo constitui um caso de aumento nos desembarques a despeito de elevado nível trófico e grande tamanho corpóreo. Os resultados concordam com recente levantamento em nível mundial, que nega existir correlação necessária entre sobrepesca e nível trófico alto, mas fatores que podem explicar os resultados do presente trabalho são discutidos.

Satellite and historical data, and statistical modeling to predict potential fishing zones for dolphinfish, Coryphaena hippurus (Perciformes: Coryphaenidae) in Colombian Pacific / Datos satelitales e históricos, y modelado estadístico, para predecir zonas de pesca potencial del pez dorado, Coryphaena hippurus (Perciformes: Coryphaenidae) en el Pacífico colombiano

Introduction: The prediction of potential fishing areas is considered one of the most immediate and practical approaches in fisheries and is an essential technique for decision-making in managing fishery resources. It helps fishermen reduce their fuel costs and the uncertainty of their fish catches; this technique allows to contribute to national and international food security. In this study, we build different combinations of predictive statistical models such as Generalized Linear Models and Generalized Additive Models. Objective: To predict the spatial distribution of PFZs of the dolphinfish (Coryphaena hippurus L.) in the Colombian Pacific Ocean. Methods: We built different combinations of Generalized Linear Models and Generalized Additive Models to predict the Catch Per Unit Effort of C. hippurus captured from 2002 to 2015 as a function of sea surface temperature, chlorophyll-a concentration, sea level anomaly, and bathymetry. Results: A Generalized Additive Model with Gaussian error distribution obtained the best performance for predicting PFZs for C. hipurus. Model validation was performed by calculating the Root Mean Square Error through a cross-validation approach. The R2 of this model was 50 %, which was considered suitable for the type of data used. January and March were the months with the highest Catch per Unit Effort values, while November and December showed the lower values. Conclusion: The predicted PFZs of C. hippurus with Generalized Additive Models satisfactorily with the results of previous research, suggesting that our model can be explored as a tool for the assessment, decision making, and sustainable use of this species in the Colombian Pacific Ocean.

Introducción: La predicción de zonas potenciales de pesca se considera uno de los enfoques más inmediatos y efectivos en las pesquerías, es una técnica importante para la toma de decisiones en el manejo de los recursos pesqueros. Ayuda a los pescadores a reducir su costo de combustible y también a disminuir la incertidumbre de sus capturas, esta técnica permite contribuir a la seguridad alimentaria nacional e internacional. En este estudio, se construyeron diferentes combinaciones de modelos estadísticos predictivos como modelos lineales generalizados y modelos aditivos generalizados. Objetivo: predecir la distribución espacial de las zonas potenciales de pesca del pez dorado (Coryphaena hippurus L.) en el Pacífico colombiano. Métodos: La variable de respuesta se expresó en escala de captura por unidad de esfuerzo, es decir, el número de individuos de C. hippurus capturados por un número total de anzuelos disponibles entre 2002 y 2015. Temperatura de la superficie del mar, concentración de clorofila, anomalía del nivel del mar y batimetría, se utilizaron como variables explicativas para los meses de estacionalidad de C. hippurus (noviembre - marzo). Resultados: El modelo con mejor rendimiento para la predicción de zonas potenciales de pesca fue un modelo aditivo generalizado con distribución de error gaussiana y función de enlace de registro, que se seleccionó en función del criterio de información de Akaike, el R2 y la desviación explicada. La validación del modelo se realizó calculando el error cuadrático medio a través de un enfoque de validación cruzada. El ajuste de este modelo fue del 50 %, lo que puede considerarse adecuado para el tipo de datos utilizados. Enero y marzo fueron los meses con mayor captura por unidad de esfuerzo y noviembre-diciembre los meses con menor. Conclusión: Las zonas potenciales de pesca previstas coincidieron satisfactoriamente con investigaciones anteriores, lo que sugiere que nuestro modelo es una herramienta poderosa para la evaluación, toma de decisiones y uso sostenible de los recursos pesqueros de C. hippurus en el Pacífico colombiano.

Abstract Introduction: The snail Hexaplex princeps is the most important gastropod in the fishery of Guerrero, but capture is not legally regulated for lack of enough studies about its reproduction, growth and other fishing aspects. Objective: To assess fishery data for H. princeps in Guerrero. Methods: From October 2016 to December 2017, we analyzed histological samples of the gonads from 6 to 13 individuals per month. We also collected data on pre-reproductive organisms captured in Costa Chica (2013 and 2014), Costa Grande (2017) and Acapulco (2019 and 2020). Results: Both sexes have five stages of gonadal development; most reproductive activity was from December to July, related to sea surface temperatures of 26 to 28 °C. The LC M in females was 94.1 mm (males: 86.1 mm). There was a high percentage of juvenile organisms in the catches (88.6 %). Conclusions: To let these snails reproduce at least once, we recommend a fishing ban from December to July, and that the minimum size of commercial capture be set at 94.1 mm.

PREVALENCE OF RESPIRATORY ILLNESS AND ASSOCIATED FACTORS AMONG FISHING TRAWLER WORKERS IN TAMIL NADU.

In India, an estimated half a billion people work in fishing-related jobs. Trawler fishermen are frequently exposed to long hours of fuel exhaust, but little is known about the adverse effects of this exposure. The aim of this study is to assess the prevalence of respiratory illness among Fishing Trawler workers and its association between the working environment quality. This crosssectional study was conducted from April 2021 to June 2021 among adults engaged in trawler fishing in Tamil Nadu using an interviewer administered semi structured questionnaire and the data was analysed using SPSS version 16. The prevalence of respiratory symptoms was 81% and respiratory illness was 36.5% with signi?cance between years of working(p=<0.05), days a month worked(p=<0.05), hours of exposure(p=<0.05), history of smoking(p=<0.05) and air quality(p=0.05). Trawler fishermen's respiratory health may be compromised by fuel exhaust and exposure duration. More attention and surveillance of trawler fishermen's occupational health is required

Bycatch of Asteroidea from shrimp trawl fishery in the southwestern Atlantic Ocean ­ Brazil

Shrimp trawling is considered a significant negative impact on the marine ecosystem, especially on the benthic community. Sea stars (Echinodermata: Asteroidea) are one of the most affected groups by unintentional catches. This study was performed at the Santana Archipelago, a Marine Protected Area in the northern region of Rio de Janeiro State, between 2008-2009. Sea stars accidentally caught by trawling were collected during open and closed season of the shrimp fisheries (Xiphopenaeus kroyeri) at depths of 5-60 m. A generalized linear zero-inflated model was applied to test for differences in capture between fishing seasons and depths. A total of 158 sea star specimens were captured. These specimens were identified as Asterina stellifera, Astropecten acutiradiatus, Astropecten brasiliensis, Astropecten cingulatus, Luidia alternata alternata, Luidia clathrata, Luidia ludwigi scotti, Luidia senegalensis. The sea stars A. brasiliensis and L. senegalensis are currently considered as vulnerable species in the Brazilian official list of threatened species. The higher capture of sea stars was shown in deepest areas, and there was no significant difference in the number of specimens between seasons. This is the first study about asteroids accidentally captured by shrimp trawling.(AU)

Vigilância popular da saúde nas comunidades pesqueiras tradicionais e ecologia dos saberes no enfrentamento à COVID-19 / Popular health surveillance in traditional fishing communities and the ecology of knowledges in the fight against COVID-19

Resumo Diante da emergência em saúde pública de importância internacional provocada pela COVID-19, trabalhadores da pesca artesanal, em diálogo com lideranças e acadêmicos brasileiros criaram, em março de 2020, um Observatório sobre os impactos dessa pandemia em comunidades pesqueiras. O objetivo deste artigo é analisar a experiência de vigilância popular da saúde de pescadores e pescadoras através de boletins diários produzidos no Observatório. Trata-se de um processo de monitoramento que possibilitou ampliar o reconhecimento da diversidade de modos de vida das populações vulneráveis que entrelaça saúde, ambiente e trabalho. O estudo utilizou metodologia qualitativa, horizontal e emancipatória e buscou aproximações à prática da ecologia dos saberes, tendo como resultados: construção compartilhada de informações e conhecimentos com base em experiências sociais heterogêneas; prática da ouvidoria coletiva com a valorização de saberes construídos nas lutas sociais; avaliação conjunta de iniquidades em saúde pública, conflitos territoriais e racismo ambiental, estrutural e institucional; orientação das lideranças sociais e captação de recursos através de editais públicos. Revela-se, assim, dinamicidade e horizontalidade de aprendizados com base na solidariedade e emancipação social a partir do interconhecimento.

Abstract Considering the public health emergency of international importance caused by COVID-19, artisanal fishing workers, engaging in a dialogue with Brazilian leaders and scholars, created an Observatory on the impacts of this pandemic on fishing communities in March 2020. The purpose of this article is to analyze the experience of popular surveillance of fishermen and fisherwomen's health through daily reports produced at the Observatory. It is a monitoring process that allowed broadening the recognition of the diversity of vulnerable populations' ways of life that intertwine health, environment and work. The study used a qualitative, horizontal and emancipatory methodology and sought approaches to the practice of the ecology of knowledges, with the following results: shared construction of information and knowledges based on heterogeneous social experiences; practice of collective ombudsman with the appreciation of knowledges built in social struggles); joint assessment of public health inequities, territorial conflicts, and environmental, structural, and institutional racism; guidance of social leaders and fundraising through public notices. Thus, the dynamics and horizontality of learning based on solidarity and social emancipation from inter-knowledge are revealed.

Derramamento de petróleo no litoral brasileiro: (in)visibilidade de saberes e descaso com a vida de marisqueiras / Oil spill on the Brazilian coast: (in)visibility of knowledges and disregard for the life of shellfisherwomen

Resumo Em 2019 um derramamento de petróleo de origem desconhecida afetou várias localidades do litoral brasileiro. Nessa pesquisa, objetivou-se apreender as percepções das marisqueiras do estuário do Rio Jaguaribe, Ceará, acerca da exposição ao petróleo e suas consequências. Utilizou-se o grupo focal como técnica para a coleta de dados e o software Iramuteq para o processamento e análise do material. Os resultados apontaram para a criação de duas categorias analíticas: implicações sociais, econômicas, produtivas e de consumo de alimentos das famílias marisqueiras; e os saberes, a participação e a vigilância no contexto de (in)visibilização da exposição ao petróleo. Percebeu-se que as marisqueiras e suas famílias são uma população muito exposta aos impactos negativos causados pelo derramamento de petróleo por se apresentarem significativos sob as perspectivas socioeconômicas, ambientais, produtivas e de saúde. Chama-se a atenção para as políticas de saúde e assistência social para as trabalhadoras, consequências na segurança alimentar, hídrica e nutricional das famílias e sobre o reconhecimento de seus saberes e práticas, construídos dentro de um modo de vida tradicional que produz e reproduz a existência numa estreita relação sociedade/natureza.

Abstract In 2019, an oil spill of yet unknown origin affected several locations on the Brazilian coast. The purpose of this research was to capture the perceptions of women shellfish gatherers in the Jaguaribe River estuary, Ceará, about exposure to oil and its consequences. The focal group technique was used for data collection and the Iramuteq software for the processing and analysis of the material. The results indicated the creation of two analytical categories: Social, economic, food production and consumption implications of shellfish gatherer families; and the knowledges, the participation and the surveillance in the context of (in)visibility of exposure to oil. It was observed that shellfisherwomen and their families constitute a population that is very exposed to the negative impacts caused by the oil spill, as they are significant from the socioeconomic, environmental, food production, consumption and health perspectives. Attention is drawn to health and social assistance policies for these fisherwomen/shellfish gatherers, with consequences on the food, water and nutrition security of families and the recognition of their knowledges and practices, constructed within a traditional way of life that produces and reproduces the existence in a close society/nature relationship.

Aproveitamento de resíduos de pescado na confecção de composto orgânico para produção de mudas de alface / Use of fish waste in the production of organic compounds for lettuce seedling production

RESUMO Há muitos estudos voltados à redução do volume de resíduos provenientes da indústria pesqueira. Esses resíduos são uma importante fonte de matéria-prima em sistemas orgânicos de produção ao serem compostados. O objetivo deste trabalho foi avaliar os parâmetros teores totais de nutrientes do composto orgânico confeccionado com resíduos de pescado, comparando-o a outras duas composições, além de utilizá-lo como substrato na produção de mudas de alface (Lactuca sativa). Na avaliação de produção de mudas de alface, utilizou-se o delineamento inteiramente casualizado, com seis tratamentos e quatro repetições. Avaliaram-se: quantidade de folhas (QF), comprimento da raiz (CR), massa seca da parte aérea (MSPA) e massa seca da raiz (MSR). Os parâmetros de matéria orgânica (MO), relação C/N e capacidade de troca de cátions (CTC) foram superiores no composto de resíduo de pescado. Para a produção de MSPA, os tratamentos T3 (composto confeccionado com resíduos de pescado) e T2 (composto confeccionado com resíduos agroindustriais da palmeira carnaúba) apresentaram as maiores médias, sendo T2 o que apresentou a maior média para MSR. Para QF, os melhores resultados (p = 0,02) foram obtidos pelo tratamento T6, cujas mudas de alface apresentaram maior QF e CR. Os resultados sugerem viabilidade na produção de mudas de alface utilizando substrato à base de resíduos de pescado.

ABSTRACT There are many studies aimed at reducing the volume of waste from the fishing industry. These residues are an important source of raw material in organic production systems when composted. The objective of this work was to evaluate the parameters of total nutrient contents of the organic compost made with fish residues, comparing it to two other compositions, in addition to using it as substrate in the production of lettuce seedlings (Lactuca sativa). In the evaluation of lettuce seedlings production, a completely randomized design was used, with six treatments and four replications. The following were evaluated: Leaf quantity (QF), root length (CR), Aerial part dry mass (MSPA), and root dry mass (MSR). The parameters of organic matter (OM), C/N ratio and cation exchange capacity (CTC) were higher in the fish residue compound. For the production of MSPA, treatments T3 (compound made with fish residues) and T2 presented the highest averages, being treatment T2 (compound made with agroindustrial residues of the Carnauba palm) presented the highest averages, with T2 presenting the highest mean for MSR. For QF, the best results (p = 0.02) were obtained by T6 treatment, whose lettuce seedlings had a greater number of leaves and root length. The results suggest viability in the production of lettuce seedlings using a substrate based on fish residues.

Consequences of a new species and different stocks of Spiny Red Lobster in Brazil / Consequências de uma nova espécie e diferentes estoques de Lagosta Vermelha no Brasil

Abstract: The Spiny Red Lobster has an important commercial role in Brazil. However, a downward trend in the production of lobsters due to overfishing has been observed and there is also a devaluation of the product in the international market due to the instability in the size pattern of lobsters commercialized. Here in Brazil we detected two issues regarding the Spiny Red Lobster: (1) According to recent studies, there are genetic and morphological differences between Caribbean and Brazilian populations, which may be considered different species and; (2) Current legislation, such as seasonal closures, does not consider the multiple probable stocks of the species, which have direct implications in management and conservation. Thus, the recognition of the Spiny Red Lobster from Brazil as Panulirus meripurpuratus and investments on population and biological research are essential to improve its management considering regional stock differences.

Resumo: A lagosta vermelha tem um importante papel comercial no Brasil, porém, uma tendência de queda na produção de lagostas devido a sobrepesca tem sido observada e há também uma desvalorização do produto no mercado internacional devido à instabilidade no comprimento das lagostas comercializadas. Aqui no Brasil, detectamos dois problemas em relação à lagosta vermelha: (1) De acordo com estudos recentes, existem diferenças genéticas e morfológicas entre as populações caribenha e brasileira e; (2) Atualmente a legislação não considera os múltiplos estoques prováveis da espécie. Desta forma, os períodos de defeso sazonais não consideram os diferentes estoques, o que tem implicações diretas no manejo e na conservação. Logo, o reconhecimento da lagosta vermelha do Brasil como Panulirus meripurpuratus e investimentos em pesquisas biológicas e populacionais são fundamentais pra facilitar seu manejo considerando diferenças regionais nos seus estoques.

Saúde das trabalhadoras da pesca artesanal: cenários desconhecidos do Sistema Único de Saúde (SUS) / Artisanal fisherwomen and workers' health: Brazilian Unified Health System unknown scenarios

Resumo Objetivo: compreender a percepção de trabalhadoras da pesca artesanal acerca dos riscos e agravos relacionados ao trabalho e das ações de promoção à saúde dirigidas a sua atividade produtiva. Métodos: pesquisa-ação com sete pescadoras e marisqueiras do rio Pacoti, em Eusébio, Ceará. A coleta de dados foi realizada no domicílio das trabalhadoras em 2019. As entrevistas foram gravadas, transcritas e seu conteúdo analisado por meio da análise de discurso. Resultados: as mulheres pescadoras têm baixa escolaridade e renda. Enfrentam condições de trabalho precárias em ambiente inóspito (manguezal). Relatam quedas, fraturas, ferimentos, afogamentos e sintomas de distúrbios musculoesqueléticos relacionados ao trabalho, porém não consideram que estejam expostas à riscos. Esses acidentes são vistos por elas como inerentes ao processo produtivo e os agravos à saúde não são percebidos como decorrentes do trabalho. Também não identificam ações de promoção de saúde dirigidas a elas. Conclusão: as situações relatadas e vivenciadas pelas trabalhadoras indicam que o serviço de saúde local ainda não atua a partir de uma visão de Saúde do Trabalhador. Há necessidade do Sistema Único de Saúde avançar na promoção da saúde, por meio de educação, vigilância e atenção em saúde com foco na prevenção de agravos relacionados à pesca artesanal.

Abstract Objective: to understand the artisanal fisherwomen's perception about the risks and health problems related to their work, as well as to the health promotion actions aimed at their activity. Methods: action research conducted with seven fisherwomen/shellfish gatherers of the Pacoti River, in Eusébio, state of Ceará, Brazil. Participants were interviewed at their home in 2019. The interviews were recorded, transcribed, and their content examined using discourse analysis. Results: our findings indicated that fisherwomen have low education and income levels, besides facing precarious working conditions in an inhospitable environment (mangrove). Although reporting falls, fractures, injuries, drownings, and symptoms of work-related musculoskeletal disorders, they do not consider that they are exposed to risks. They see these accidents as inherent to the production process and do not perceive their health problems as resulting from the working conditions to which they are subjected. They also do not identify the existence of health promotion actions aimed at fisherwomen and shellfish gatherers. Conclusion: the situations experienced and reported by the workers indicate that the local health service is not committed to occupational health yet. Brazilian Unified Health System (SUS) must advance in health promotion through education, surveillance, and healthcare, aimed at preventing artisanal fishing work-related diseases.

Consumo y comercio de tortugas continentales en la subregión la Mojana, Sucre, Colombia / Consumption and commerce of continental turtles in the la Mojana subregion, Sucre, Colombia

Los quelonios ampliamente utilizados como fuente de alimento y para comercialización, en todo el departamento de Sucre. Esto atenta contra el buen estado de la diversidad biológica y los ecosistemas donde habitan. Se determinaron las especies que son utilizadas para dichas actividades. Para conocer la magnitud de esta situación y contribuir en lo posible a plantear medidas de mitigación, se aprovecharon las capturas realizadas por pescadores de varias localidades en la sub región La Mojana, en el departamento de Sucre y se realizaron encuestas informales a esos trabajadores. Las hicoteas fueron capturadas en periodo baja lluviosidad, cuando se encuentran ovopositando y no se tuvo en cuenta la talla para su captura. Todos los individuos fueron medidos y pesados y se les hizo palpación para determinar la presencia o ausencia de huevos oviductales. Fueron capturados más de 200 individuos de ambos sexos, pertenecientes a cuatro especies de quelonios. Una de las especies se encuentra en peligro crítico (CR) Chelonoidis carbonaria, Rhinoclemmys melanosterna está reportada como casi amenazada (NT) y Kinosternon scorpioides es vulnerable (VU). La más abundante y utilizada fue Trachemys callirostris. Las técnicas utilizadas por los pescadores no son las más adecuadas, porque no solo dañan a los animales sino al ecosistema, adicionalmente, la situación económica. La situación económica de los pescadores es muy grave y no tienen otras fuentes de empleo. Se recomienda realizar actividades de educación ambiental, capacitarlos sobre pesca racional y apoyar la creación de zoocriaderos, lo que mitigaría su extracción del ambiente natural y crearía otras fuentes de trabajo.

Freshwater chelonians are widely used as a source of food and for commercialization, throughout the department of Sucre. This threatens the good state of biological diversity and the ecosystems where they live. The species that are used for these activities were determined. In order to know the magnitude of this situation and contribute as much as possible to propose mitigation measures, the catches made by fishermen from various localities in the La Mojana sub-region, in the department of Sucre, were used and informal surveys were conducted with these workers. The hicoteas were captured in the dry period, when they are laying eggs and the size was not taken into account for their capture. All individuals were measured and weighed and palpated to determine the presence or absence of oviductal eggs. More than 200 individuals of both sexes were captured, belonging to four species of chelonians. One of the species is critically endangered (CR) Chelonoidis carbonaria, Rhinoclemmys melanosterna is reported as near threatened (NT) and Kinosternon scorpioides is vulnerable (VU). The most abundant and used was Trachemys callirostris. The techniques used by fishermen are not the most appropriate because they harm the animals and the ecosystem. The economic situation of the fishermen is very serious and they have no other sources of employment. It is recommended to carry out environmental education activities, train them on rational fishing and support the creation of breeding farms, which would mitigate their extraction from the natural environment and create other sources of work.
