Este trabalho apresenta um estudo de caso sobre o papel da Câmara Técnica de Pesca (CTP) do Consórcio Intermunicipal Lagos São João (CILSJ) na mediação de conflitos de gestão da pesca artesanal na região da Lagoa de Araruama (LA). A CTP é gerida pelas prioridades da Política Nacional de Recursos Hídricos (PNRH), preservacionista, em oposição a Política Nacional de Desenvolvimento Sustentável da Atividade Pesqueira (PNDSAP), com fins de exploração econômica. Na Bacia Hidrográfica Lagos São João, o CILSJ, prioriza as ações de conservação e manutenção dos corpos de água para o abastecimento, deixando em segundo plano a recuperação dos estuários em que lança o esgoto tratado e o não tratado, justamente os locais onde ocorre a pesca. O sujeito da pesquisa foi a representação dos pescadores, que são os presidentes das colônias. O levantamento de dados ocorreu por meio de entrevistas, observação direta, observação participante, documentos, filmes, fotografias, depoimentos, considerando também os atores da gestão pública da pesca local, estadual e federal. As entrevistas foram examinadas com base em análise textual. A abordagem da pesquisa é qualitativa. A pesca artesanal praticada na localidade é de pequena escala, se utiliza de embarcações miúdas, o trabalho ocorre em regime de companha e/ou familiar. O co-manejo é a metodologia de gestão dos recursos comuns mais utilizadas na atualidade na pesca artesanal. Os dados revelaram que o modelo de co-manejo da CTP não é o mais adequado para mediar os conflitos da pesca na localidade. Este estudo constatou que existe a união das colônias por meio da CTP, mas mesmo assim, o mecanismo CTP, não permite que maiores conquistas sejam alcançadas pelos pescadores, tendo em vista que o modelo de co-manejo é apenas consultivo, em que o poder público consulta, mas toma a decisão de forma autônoma sem compartilhar o poder de gestão, desse modo não há o empoderamento por parte dos pescadores. Assim, se faz urgente a substituição do sistema de co-manejo exercido pela CTP, por outro que possibilite maior participação dos pescadores e não só das suas representações; autonomia de gestão dos pescadores; possibilidade de financiamento além das atividades de preservação, mas também de desenvolvimento econômico da pesca. Outros modelos de co-gestão passíveis de substituir a CTP são a Reserva Extrativista (RESEX), a Reserva de Desenvolvimento Sustentável ou Fórum de Pesca tendo em vista serem esses os modelos de co-manejo mais bem sucedidos no país e inclusive em parte da região, a RESEX de Arraial do Cabo. A constatação desta pesquisa do papel exercido pela CTP no que tange o co-manejo na LA é compatível com as deficiências dos modelos de co-manejo da pesca no Brasil, com menor empoderamento dos pescadores diante do poder público e da própria submissão da gestão pública da pesca diante da gestão pública do ambiente. Apesar de haver certa produção acadêmica sobre a pesca, a literatura sobre a gestão da pesca na localidade da LA é escassa, o que dificulta o desenvolvimento da sustentabilidade pesqueira e da aplicação de qualquer plano de manejo e indica a urgência do desenvolvimento de maiores investigações, no que este trabalho procura oferecer alguma contribuição.

Macrobrachium rosenbergii is a freshwater prawn which presents agonistic behavior and heterogeneous growth. It is known that captive conditions can intensify agonism causing injuries and decreased survival, generating a condition of poor welfare. Based on this, we aim to investigate the behavior of M. rosenbergii in the juvenile phase according to different types of shelter and frequencies of feed offer, emphasizing their agonistic behavior. For this, juveniles were observed in the laboratory in three steps. At step I we characterized the behavioral profile; prawns were kept in eight aquariums (27 prawns/m2 ), identified and observed four times along both phases of 24 h light cycle. At step II (2 experiments), we evaluated the use of shelters (brick or polyethylene rolls) and their influence on agonism by the animals. For classification of animals in dominance rank, the method used was David's Score. At step III (3 experiments), we evaluated different frequencies of feed offer on the behavior of individuals, in particular agonism. Results showed that juveniles do not present a pattern activity/inactivity between the phases of the light cycle. We identified a dominance hierarchy among individuals taking advantage of access to food by the dominant, which showed greater weight gain although the frequency of intake did not differ between individuals. The type of shelter influenced the behavior of animals. Brick shelter generated a higher frequency of permanence and a reduction in the frequency of agonistic interactions. The distribution of food more frequently throughout the day, decreased the motivation of animals for food, as well as to fight. Prawns fed four times showed lower frequency of feed intake and agonistic interactions. Thus, we conclude the shelters which reduce animal’s detection by coespecifics and offer the food four times along the day reduce agonistic behavior. This result causes na improvement in life quality of the prawns and also in its quality as final product.

T he socio - economy of the coastal municipalities of Rio Grande do Norte semiarid coast was analyzed th r ou g h by the actors, ant hropogenic implications, fishing environment and composition of its fish fauna, as well as the trend of product ion landed by the artisanal fleet with the aim of identifying the sustainability and management. In this study, were used participatory methodologies, monthly data of rainfall between September 2001 and December 2010; landings of the artisanal fleet during January 2001 to December 2010; and socioeconomic (IBGE, 2002/2010), (IDEMA, 2011/2012), (MPA, 2010; 2012), UNDP and MS (2013). Based on these data, we performed analysis of variance were performed using the method of Analytic Hierarchy Process (HAP) and s tatistical models of multiple regression and time series. It was identified that the occupation of the coastal and marine zone through salt industry, tourism, shrimp farming, oil and gas and wind energy reconfigured the environment and attracted new actors . Rainfall influenced the catches, of which 35% occur in the rainy season, 40% in the dry season and 25% independent. Production increased 55%, in the period analyzed , being landed in 31 ports spread over 11 municipalities, cap tured in environments mangrov e/ estuarine (23%), coastal (46%) and oceanic (31%). Despite market up 41 species, were commercialized in the region production concentrated in eight, mainly landed in Macau and Caiçara North, by vessels of small and medium - sized (motorized and sailboats) . Highlights included three species ( Hirundichthys affins , Coryphaena hippurus and Opisthonema oglinum ), which together accounted for 63.3% of the whole volume. It was found that the motorized vessels tripled in number while sailboats reduced by half. Landin gs by different types of vessels tend to increase over time, while the small sailboats vessels, decrease. The introduction of more new motorized vessels and sailboats also tend to increase production. The study concluded that GDP and HDI of coastal countie s increased however inequality persisted. The potential of artisanal fishing is in the stage “ unfavorable ” of development and the trend in fish production is to grow over time and with the entry of more vessels. However, it is urgent that the state actions to promote and enhance planning to restore fish stocks in a sustainable and profitable fisheries standards. Therefore, it is recommend the strategic use of natural resources in a sustainable development perspective.

Artisanal fishing is one of the important economic activities of Rio Grande do Norte (RN), becoming the main form of survival and income for many families. The southern coast of RN has strong fishing tradition, both in exploitation of fish as in the collection of mollusks on the banks of Guaraíra Lagoon (APA Bonfim-Guaraíra). In recent years, fishing communities have become more vulnerable to outside influences, since the socio-economic and environmental changes are exposed. These changes require adjustments to the fishermen to different environmental conditions, as the social and natural systems are driven by reorganization and upgrading processes. The living conditions in fishing communities are objective and necessary in different ways, according to a selection that is cultural, so adaptable. This study has the general objective to analyze the main environmental changes in fishing communities, based on the understanding of fishermen and mollusk fisherwomen about this problem. The specific objectives searched to: describe the socioeconomic profile, prospects and difficulties of fishermen and mollusk fisherwomen; investigate the major social and environmental changes in the fishing communities of Patané and Camocim (Arez/RN). The methodology was qualitative-quantitative with the techniques of observation in the field and open and semistructured interviews applied to representatives of Cologne fishing, fishermen and mollusk fisherwomen. Between the months of January to July 2014 were applied semistructured interviews with 41 interlocutors in Patané and 23 of Camocim; totaling 64 people. The results indicated that the interlocutors are aged 40 to 60 years; have only completed elementary school level; are married and have children; survive on less than a minimum wage income and they are not receiving employment insurance. The case study also revealed that the socioeconomic and environmental problems reflected in changes in reproduction, organization and social division of labor, which generates adaptive changes of families to external influences, resulting directly from other economic activities and market pressure and indirectly from tourism. Therefore, adaptations to changes scenario presented as favorable to economic aspects and unfavorable to the social and environmental aspects. In short, the fishery develops on technical, bureaucratic and financial obstacles, in the everyday needs of men and women is the determining factor in willingness to continue exercising fishing and shell fishing on Guaraíra Lagoon, space representing relations social, practices and customs transmitted in the course of local history through social memory of the oldest to the youngest.

This work was developed with the objective of proposing a simple, fast and versatile methodological routine using near-infrared spectroscopy (NIR) combined with multivariate analysis for the determination of ash content, moisture, protein and total lipids present in the gray shrimp (Litopenaeus vannamei ) which is conventionally performed gravimetrically after ashing at 550 ° C gravimetrically after drying at 105 ° C for the determination of moisture gravimetrically after a Soxhlet extraction using volumetric and after digestion and distillation Kjedhal respectively. Was first collected the spectra of 63 samples processed boiled shrimp Litopenaeus vannamei species. Then, the determinations by conventional standard methods were carried out. The spectra centered average underwent multiplicative scattering correction of light, smoothing Saviztky-Golay 15 points and first derivative, eliminated the noisy region, the working range was from 1100,36 to 2502,37 nm. Thus, the PLS models for predicting ash showed R 0,9471; 0,1017 and RMSEP RMSEC 0,1548; Moisture R was 0,9241; 2,5483 and RMSEP RMSEC 4,1979; R protein to 0,9201; 1,9391 and RMSEP RMSEC 2,7066; for lipids R 0,8801; 0,2827 and RMSEP RMSEC 0,2329 So that the results showed that the relative errors found between the reference method and the NIR were small and satisfactory. These results are an excellent indication that you can use the NIR to these analyzes, which is quite advantageous, since conventional techniques are time consuming, they spend a lot of reagents and involve a number of professionals, which requires a reasonable runtime while after the validation of the methodology execution using NIR reduces all this time to a few minutes, saving reagents, time and without waste generation, and that this is a non-destructive technique.

Contemporáneamente, parece que la relación entre el Estado y la sociedad civil ha sido modificada por los patrones de neoliberalismo que se propagan a la ideología de la responsabilidad social y, por lo tanto, la expansión del “Tercer Sector”. Así, desde la década de 1980 las Organizaciones No Gubernamentales surgen en Brasil, alcanzando un papel importante en la sociedad, como la realización de sus actividades y proyectos. Anteriormente había organizaciones, pero ahora reconocidas como ONG en este contexto. Así es como cuantitativamente se estructuraron las organizaciones de todo el país y sus acciones se vuelven más relevantes. El surgimiento de las ONG en Brasil se asocia con la lógica liberal y neoliberal que transfiere a la empresa la tarea de cuidar a los incapaces pobres y excluidos. Esta ideología trata de minimizar las necesidades sociales donde las obras del gobierno no son suficientes. Esta investigación tiene como objetivo comprender a través del análisis de entrevistas y estudio de caso como el “Tercer Sector” ha influido en la población de Felipe Camarão, Natal/RN. El objetivo principal de esta investigación es continuar el estudio y ampliar las reflexiones sobre las contradicciones y los conflictos existentes entre las organizaciones del “Tercer Sector” que trabajan en el lugar, teniendo como selección una asociación, una fundación y una ONG que trabaja en el barrio, analizar si hay o no una articulación entre las organizaciones investigadas.

Inflammation is combined of a vascular and a cellular reaction, resulting in different cells and tissue responses, both the intravascular and extravascular environment. As the inflammatory process occurs, coagulation proteases, in particular thrombin (FIIa), are able to initiate various cellular responses in vascular biology and therefore is often observed activation of other biological systems, leading to complications during an event inflammatory, such as thrombosis and angiogenesis. Thus, antagonists molecules of these events are interesting models for the development of novel anti-inflammatory drugs. Thereby, it is worth stressing the glycosaminoglycans (GAGs), which are able to interact with several proteins involved in important biological processes, including inflammation and coagulation. Therefore, this study aimed to evaluate the anti-inflammatory, antithrombotic and anti-angiogenic potentials, as well anticoagulant of a dermatan sulfate-like GAG (DS) extracted from the Litopenaeus vannamei cephalotorax. The compound was obtained after proteolysis and purification by ion-exchange chromatography. After total digestion by DS-like compounds digesting lyases (chondroitinase ABC), the DS-like nature was revealed, and then called DSL. The shrimp compound showed reduced anticoagulant effect by the aPTT assay, but high anti-IIa activity, directly and through heparin cofactor II. On inflammation, the compound had a significant inhibitory effect with the reduction of proinflammatory cytokines. Potential Inhibitory were reported in the antithrombotic and anti-angiogenic assay, the latter being dose dependent. As for anti-hemostatic activity, the polysaccharides did not induced significant bleeding effect. Thus, the results shown by the shrimp DS-like compound indicate this glycosaminoglycan as a biotechnology target with prospects for the development of new multipotent drugs.

Este estudo descreve o estilo de vida e vulnerabilidade dos adolescentes do bairro Felipe Camarão em Natal-RN, a fim de compreender seus comportamentos, conforme vulnerabilidades identificadas. Foram aplicados 145 questionários semi-estruturados entre os adolescentes de 12 a 18 anos, no período de janeiro, a abril de 2005. O estilo de vida descrito, conforme os dados colhidos, informa que 92,4% sabem da importância de se alimentar bem, 86,9% têm sono preservado; 76,5% têm boa relação com seus pais. Porém, 86,9% afirmaram não haver área de lazer/diversão no bairro, enquanto os 31,0% não responderam sobre higiene corporal; 41,4% consomem drogas lícitas (maioria álcool), enquanto 37,9%, as ilícitas (maioria cola); 51,7% dizem que não conversam sobre sexo, enquanto 30,3% conversam com suas mães; 38,0% estão sexualmente ativos, iniciados entre 13 a 16 anos. Os comportamentos de alguns adolescentes estudados indicam um estilo de vida saudável, enquanto outros demonstram justamente o contrário, através de práticas como: pouca participação no lazer, por falta de opção; consumo de drogas lícitas e ilícitas; a falta de diálogo com os pais sobre sexo; relacionamento sexual precoce, somados às condições econômicas e sociais desfavorecidas que os expõem à adoção de um estilo de vida que implica em vulnerabilidade
