Composição ictiofaunística e estratégias reprodutivas de quatro espécies de peixes nativos da Bacia Hidrográfica Piranhas - Assu, Rio Grande do Norte

This study focuses on the fish fauna composition and reproductive strategies of four native fish species in relation to environmental variables of the Piranhas-Assu hydrographic basin of the Caatinga biome, Rio Grande do Norte, Brazil. Fish and environmental data were collected monthly during the period September 2008 to February 2010, in the Marechal Dutra reservoir and River Acauã a tributary of Piranhas- Assu. The fish were measured, weighed and dissected, and the gonads were removed, weighed and examined macroscopically for identification and determination of gonad maturation stages. The results of this work generated seven articles. The first article is about the fish fauna composition of the Piranhas-Assu hydrographic basin, Rio Grande do Norte. The 602 fish samples captured were distributed in four orders (Characiformes, Perciformes, Siluriformes and Synbranchiformes), 11 families and 22 species, of which 17 are endemic to the Caatinga ecoregion. The order Characiformes was more representative followed by Perciformes, Siluriformes and Synbranchiformes. The second article is about the length-weight relationship and growth of seven native fish species Crenicichla menezesi, Cichlasoma orientale, Triportheus angulatus, Psectrogaster rhomboides, Pimelodella gracilis, Prochilodus brevis and Leporinus piau from a semiarid Brazilian reservoir. The third article is about the reproductive aspects of Crenicichla menezesi. Males were larger, heavier and with a slight predominance as compared to females. Four stages of gonadal development were characterized, being immature, maturing, mature and spent. The females reached sexual maturity earlier than males, with an average fecundity of 398 oocytes per batch. The spawning was partial with a long reproductive period. The fourth article deals with the reproductive strategy of Leporinus piau a neotropical freshwater fish in semi-arid region of Brazil. The population of L. piau (n = 211) showed a slight predominance of males (55%), with larger and heavier females. The males matured earlier than the females. This species presented total spawning, with an average fecundity of 55,000 mature oocytes. Rainfall and concentration of dissolved oxygen acted as influential factors during the spawning season. L. piau shows a seasonal reproductive strategy. The fifth article is related to the morphometric-meristic characteristics and reproductive aspects of freshwater sardine, Triportheus angulatus from River Acauã of the Caatinga biome. There was a predominance of larger females, reaching first maturation before males. There was total spawning during the rainy period of the region. The sixth article reports on the reproductive strategy of Psectrogaster rhomboides. The sex ratio was 1M: 1F, with negative allometric growth. Males reached sexual maturity earlier than females Females and males showed four stages of gonadal development and spawned during the rainy season. The fecundity was low and this species presented total spawning. The seventh article reports on the dynamics of territorial behavior of Crenicichla menezesi. Ten agonistic behaviors displayed by the males were observed: frontal and lateral threat, chasing, circular chasing, perpendicular, lateral and mouth attacks, escape, parallel positioning and stationary. The formation of four social groups was observed among males: without interaction; interaction with submission and escape; with frontal and lateral agonistic interactions. In social interactions between males and females, it was observed that the larger males interacted more among themselves and with the larger females. The large male established its territory and the two small males along with the small female were excluded from the other groups. These studies clarified the fish fauna composition and reproductive strategies of four native species Crenicichla menezesi, Leporinus piau, Triportheus angulatus and Psectrogaster rhomboides of the Piranhas- Assu hydrographic basin of the Caatinga biome, Rio Grande do Norte, Brazil.

Estratégia reprodutiva do peixe-voador, Hirundichthys affinis e do peixe agulha preta, Hemiramphus brasiliensis no litoral de Caiçara do Norte, Rio Grande do Norte, Brasil

The flyingfish, Hirundichthys affinis (Günther, 1866) (Exocoetidae) and ballyhoo half beak, Hemiramphus brasiliensis (Linnaeus, 1758) (Hemiramphidae) are marine fish species of commercial value, which contribute to artisanal fishery production of Rio Grande do Norte, Brazil. Besides the economic importance, these fish are important from an ecological point of view, being components in pelagic food chain, where they are the preferred prey of larger predators of high commercial value. This study aimed to determine the reproductive strategies of H. affinis and H. brasiliensis and the fishery production of H. affinis in the northern coast of Rio Grande do Norte. The results are presented in the form of six cientific articles and a review paper. The first article presents the morphometric measurements and meristic counts which confirmed the taxonomic status, population structure in length-weight and the gonad development of H. affinis through macroscopic observations of the ovaries and testes. Females of this species were bigger and heavier than males. The second article describes the reproductive tactics, such as, sex ratio, length at first sexual maturity, histological aspects of gonads, fecundity and spawning season, that indicate the reproductive strategy of H. affinis. The third article shows annual changes in the fishery production of H. affinis in Caiçara do Norte, during the period of 1993 to 2010, emphasizing the relevance of this fish in total fishery production of Rio Grande do Norte, besides registering the fall in production in the years 2008 to 2010. The fourth article describes the population structure, with respect to the length and weight, the length-weight relationship, growth type and sex ratio of Hemiramphus brasiliensis. The fifth article describes the reproductive biology of H. brasiliensis, with details about sex ratio, length at first sexual maturity, fecundity, type of breeding and spawning season. The sixth article deals with the reproductive strategy of H. brasiliensis. The review paper presents the topic of age determination of tropical fish using analysis of otoliths. Both species use the coastal waters of Caiçara do Norte for reproductive purposes. The flying fish, H. affinis migrates from the oceanic waters to the coastal waters to reproduce, coinciding with the rainy season. H. affinis presents total spawning and a seasonal reproductive strategy. However, H. brasiliensis lives and reproduces in the coastal waters displaying partial spawning and an equilibrium reproductive strategy

Estrutura da Comunidade de Lagartos de um remanescente de mata atlântica do Estado do Rio Grande Do Norte, Brasil.

As part of a broader project, Diversity and Distribution Patterns of Floristic and Faunistic composition of remnants of Potiguar s Atlantic Forest, as subsidies to conservation , that subsidizes a group of institutional research, This study aimed to evaluate the structure of the assemblage of lizards a remnant of the of the northern Atlantic Forest, identifying ecological factor (s) that contribute to the coexistence of sympatric species. Additionally, we studied the thermal ecology and thermoregulatory behavior of umbrophily and heliophily species live the Parque Estadual Mata da Pipa (PEMP), a remnant of Atlantic forest located in the Tibau do Sul municipality of, Rio Grande do Norte State, Brazil. It is one of the largest remnants of the Atlantic Forest and has an area of approximately 290 ha. The study was performed by four excursions to the field for 20 days each, when active search and pitfalls traps were used to record and colleted specimens in different habitats of the area. We recorded the presence of 19 species of lizards, of which seven are typical of forest areas, three are endemic Atlantic Forest, these two northern and one are new record for the Rio Grande do Norte. The use of resources, the results showed that phylogenetically related species do not always use a similar way the resources available; the feeding niche was the segregated component of the species that overlapped extensively in the use of space and vice versa. To examine the thermal ecology and thermoregulatory behavior of Kentropyx calcarata and Coleodactylus natalensis, we recorded the clocal temperature (Tc), oh the substrate (Ts) and of the air (Ta) to investigate what of these are the source of heat more important to the temperature s body of these lizards. Behavioral observations were conducted to analyze strategies to optimize the acquisition of heat. The air temperature explained most strongly to variation in body temperature of K. calcarata, while the temperature of the substrate to C. natalensis. As for the behavioral observations, they confirmed that K. calcarata is an active thermoregulatory; C. natalensis is a passive thermoregulatory.

Estimativa populacional e uso do hábitat do boto-cinza (Sotalia guianensis) no litoral sul do Rio Grande do Norte

Four areas are known as of frequent usage by Guiana dolphins (Sotalia guianensis) in the south coast of Rio Grande do Norte state, northeast Brazil: Tabatinga, Pipa, Lagoa de Guaraíras and Baia Formosa. This extension of 40 km of shoreline is under increasing anthropogenic impacts due to continuous development of the coastal areas and vessel traffic. The objective of this study was to investigate aspects of population biology and habitat use of the population of Sotalia guianensis in the south coast of Rio Grande do Norte. It was applied the photo-identification technique and posterior methods of capture-recapture for population estimation (POPAN extension in MARK). The distribution, movement and site fidelity of the dolphins were analyzed trough the geographic information system (GIS) and group characteristics and behavior trough non-parametric statistics. Field work was conducted on board a 10m motor vessel from March 2008 to March 2009. Photo-identification effort was 329h with 113h of direct observation of the dolphins. The population estimatives for each area: Tabatinga: 75 (63-92); Pipa 105 (88-129); Lagoa de Guaraíras: 27 (18-54) e Baia Formosa: 112 (89-129) individuals. Total population estimative was: 223 (192 a 297). High site fidelity was detected for only part of the population (<15%) as low site fidelity and transients individuals were also detected (>20%). It was observed frequent movements between Tabatinga, Lagoa de Guaraíras and Pipa, but not Baía Formosa. This suggests a division in two communities along this shore extension: one in Pipa and other in Baía Formosa. Group size was small, most groups with up to 10 dolphins. The areas were use intensively, only in Lagoa de Guaraíras dolphins were not seen in all field trips. Lagoa de Guaraíras is an area used by small groups exclusively for foraging. In Tabatinga and Pipa dolphins concentrated close to the shore, in the inner sector of the area and the main activity is also foraging. Significant larger groups were seen in socializing behavior but there was no difference in group size between the inner and external sectors of the area. The presence of calves and juveniles were significant greater in the inner areas of Tabatinga and Pipa, confirming the hypothesis that these beaches are also used for parental care. In Baia Formosa dolphins concentrated in the outer sector and foraging was also predominant. Significant larger groups were seen in the outer sector, mainly engaged in mixed behaviors of travel/foraging, possibly in some kind of group foraging. Calves and juveniles were significant more present in the outer sector where group size was also larger. In general there was no difference in area usage and period of the day. Sotalia guianensis has characteristics that make the species vulnerable to human activities such as small population concentrated in patches of suitable habitats restrict to coastal areas. We hope that this study bring new information for the species and help for the adequate management of the area in order to assure the presence of the dolphins as well as its behavior pattern and gene flow betweencommunities.

Estudo sobre orçamento de atividade do Boto Cinza (Sotalia guianensis) no litoral sul do Rio Grande do Norte

A fundamental analysis on Behavioral Ecology is the construction of Activities Budget, which can be defined as the quantification of the time that each animal uses in activities that are important for its survival and reproduction. Initially developed for theoretical studies about Optimal Foraging, the construction of Activities Budgets has recently being used for analyses in Conservation Biology. However, the measurement of behavior through an adequate methodology that allows the comparison between different samples is a challenge for researchers in the area of Ethology. This problem is even bigger for the students of cetaceans behavior due to the difficulty of visualization of these animals. The present work deals with two aspects of the specialized literature on cetaceans: i) it explores possible variations of results in quantification of behavioral states decurrent of the application of different methods of data collection, and ii) it describes the activity budget of a population of Sotalia guianensis that inhabits coastal waters, south Rio Grande do Norte. The results showed that the use different methods of data collection result in significant differences, but of small scale, in the quantification of the behavioral frequency. The activity budget of Sotalia in the area here analyzed was similar to that described for other populations of this species inhabiting typically estuarine habitats. Tide and day-hour did not influence the dolphin s behavior, however, significant differences were found related to the position of the animals within the area. These results are discussed considering the dietary and behavioral flexibility of the species, contributing to the scientific knowledge and offering information that will be useful in comparative studies and for analyses on the determination of areas for species conservation

Saúde psíquica e condições de trabalho dos profissionais de saúde nos hospitais da Universidade Federal do Rio Grande do Norte

A tese se propôs a avaliar a relação entre saúde psíquica e condições de trabalho em dois hospitais da Universidade Federal do Rio Grande do Norte, a saber: Hospital Universitário Onofre Lopes e Hospital Universitário Ana Bezerra. Adotou como ponto de partida epistemológico a abordagem psicossociológica, considerando que a compreensão sócio-histórica do contexto é indispensável para entender os fenômenos em análise. As condições de trabalho e a saúde psíquica foram abordadas interdisciplinarmente, fundamentando a construção de um modelo compreensivo de saúde psíquica que orientou a investigação. O caminho metodológico utilizado foi a pesquisação. Essa foi desenvolvida, utilizando técnicas como análise documental, observação participante, entrevistas não estruturadas, grupo focal e aplicação de um protocolo de pesquisa composto pelo questionário de condições de trabalho, pelo Questionário de Saúde Geral (QSG-60), pela Escala de Bem-Estar Afetivo no Trabalho (JAWS-12) e por questões sociodemográficas. A análise dos resultados mostrou que os escores sintomáticos de saúde psíquica variam por hospitais e que a saúde psíquica sofre influência das condições de trabalho, sobretudo em aspectos referentes a três dimensões: condições físicas e materiais; processos e características do trabalho e o ambiente sociogerencial. Em referência à primeira dessas dimensões, destacaram-se a exposição aos riscos psicobiológicos e de acidentes, bem como as exigências de esforço físico. Na segunda dimensão, a complexidade das atividades e a responsabilidade implicada nas mesmas. E, na última, os fatores de organização da atividade, violência e ambiente conflitivo. Como a relação do indivíduo com seu contexto é dialética, os resultados encontrados corroboraram que quanto mais as condições de trabalho são desfavoráveis, maior a afetação da saúde psíquica e dos afetos com relação ao trabalho, repercutindo novamente no ambiente de trabalho. Portanto, ações de melhoria das condições de trabalho precisam ser estabelecidas para resultar, no efeito inverso, proporcionando o aumento dos afetos positivos e a redução dos sintomas psíquicos

Inserção e atuação profissional do psicólogo no campo das políticas sociais no Rio Grande do Norte

Since the first years of the regulation of Psychology as a profession in Brazil, it has been carried out studies on the academic graduation, practice, workplace and the social commitment of the category. Despite the diversity of goals and propositions, these studies show that psychologists have been significantly inserted into the social policies field, implying changes in the profession. Since the 1980s, researches in Rio Grande do Norte corroborate the results of national studies. The aim of this paper is to study the insertion and professional career of psychologists in the social policies field in Rio Grande do Norte. In order to accomplish the final results of this paper, it was developed an exploratory research, with the use of a questionnaire, comprised of four parts: general data, academic graduation, complementary graduation and professional experience. The results show three groups of information: characterization, insertion and professional performance. It has been verified expressive insertion of psychologists into the social policies field (41%). The socio-demographic and graduation characteristics are not different from those shown by literature: women, young, from families with an average of 7 to 15 minimum wages. Most of them graduated from public institutions and with post-graduation studies in clinical area. The professionals studied seem to be in worse working conditions compared to the rest of the category, which are also in unfavorable conditions, especially the psychologists who work in social assistance institutions, which present greater problems in its structure. The activities developed do not show anything new, reserving conservative practices instead of effective innovations, emphasizing the discussion on the profession for not considering demands presented to the psychologists in the social policies field. With unique scenario, the eproduction of liberal values corroborates classic performance standards; an unpolitical and uncritical practice is diffused. It is then reconsidered the importance of critical studies that organize goals to the category, with the aim of political transformation concerning the current scenario.

A água nossa de cada dia : percepção, uso e predisposições comportamentais de alunos do ensino médio de Natal, Rio Grande do Norte

Embora a escassez de água seja reconhecida como um dos principais problemas mundiais a ser enfrentado pela humanidade, padrões comportamentais ecologicamente insustentáveis ainda persistem. Assim, o objetivo deste estudo foi analisar determinantes do comportamento pró-ambiental relativo à água, bem como os significados que lhe são atribuídos por alunos do ensino médio do Centro Federal de Educação Tecnológica do Rio Grande do Norte, em Natal. Compuseram a amostra de conveniência 315 estudantes, 146 mulheres e 169 homens, que responderam a um questionário sobre uso e percepção da água, contendo também indicadores de pró-ambientalismo, cuidado ambiental, desenvolvimento sustentável, perspectiva temporal, externalidades e coletivismo, além de inquérito sócio-demográfico. Para os participantes, água é sinônimo de vida, muito embora a relação que mantém com ela parece dúbia e, muito mais funcional que ecológica; consideram-na um recurso finito, um patrimônio indispensável à vida, contudo não foi observada coerência entre as concepções manifestadas e os comportamentos auto-relatados de uso da água. Os resultados encontrados apontaram preditores importantes do comportamento pró-ambiental relativo à água: sexo do respondente, Escala Novo Paradigma Ecológico e deixar forma de contato para participar de campanhas futuras. Seja para aprofundamento teórico em novos estudos, seja para auxiliar na elaboração de programas de educação ambiental, que poderiam contribuir para inibir os efeitos de uma cultura de consumo e de uma visão utilitarista da água, ampliando esforços individuais e coletivos para a preservação de bens comuns, como a água. Palavras-chave: psicologia ambiental; sustentabilidade; água; comportamento próambiental. x xi Abstract Although water scarcity is recognized as one of the main world-wide problems to be faced by human kind, ecologically unsustainable patterns of behavior still persist. Thus, the objective of this study was to analyze pro-environmental behavior related to water, as well as meanings associated to it by high school students of Federal Center of Technological Education of Rio Grande do Norte, in Natal. The convenience sample was composed by 315 students, 146 women and 169 men, who answered a questionnaire about use and perception of water, containing indicators of proenvironmentalism, environmental care, sustainable development, time perspective, externalities and collectivism, besides socio-demographic items. According to participants, water is synonymous of life, even though the relationship they present with it is ambiguous, much more functional than ecological; they consider it a finite resource, an indispensable life patrimony, however there was no coherence between such conceptions and the self-reported behaviors of water use. Results indicated three important predictors of pro-environmental behavior: sex of respondent, New Ecological Paradigm Scale and telephone/address left for eventual contact to participate in future environmental campaigns. They may be used in additional studies for theoretical development, or to assist in the planning of programs of environmental education, aimed at the inhibition of the effects of a culture of consumption and of an utilitarian perception of water, extending individual and collective efforts towards the preservation of common resources as water

Gestão pública em saúde mental: um estudo em CAPS com gerência pública e privada do Rio Grande Do Norte

Currently, several models of management services from the public administration are in operation in Brazil following a global trend. Besides the traditional public management operated in SUS, there are ongoing experiments of privately management in the public health services. Accordingly, we have developed an investigation into two Psychosocial Care Centers operating between these two forms of financial resources management: the first is the CAPS II - PAR situated in the municipality of Parnamirim whose form is private and the second is the CAPS II West Christmas is that the municipal government. We seek to know the workings of services, planning forms and criteria for use of financial resources, identify differences between departments on ways to run and see how technicians and users participate in the planning and management of these resources. Documentary Research was conducted by the municipal Christmas and the financial administration of the CAPS service in Parnamirim. Were conducted an interview with manager (mental health coordinator of Natal) and another interview with an employee of planning department in the Health Department of Natal, an interview with the coordinator and financial administrator of CAPS - PAR and two groups of discussion taped conversation with semi structured script interviews with six technicians in CAPS PAR and six professionals crowded in CAPS - West.Differences were observed in the management of resources funded from four blocks of discussion and analysis of results, where the privately-run service for the direct management and bureaucracy without being discussed and planned spending on staff, as well as through meetings with users, the use of the financial resources available in box; already in service with municipal public administration there is a hierarchy, this answering the coordination of mental health and the local health department that centralizes resources and defines their spending. There are meetings with patients and families, but the demands are limited as to what can be sued because of the manager s authorization. Such differentiation would be related to differences in the articulation of public management with the different types of possible management in public services, where from the implementation of new public administration in the Brazilian s State Management Reform initiated in the second half of the 1990s, benefit management services with private regime, with autonomy and direct transfer of resources

A presença da produção científica em psicologia na formação de psicólogos do Rio Grande do Norte

The present research aimed to analyze the presence of national scientific production in undergraduate studies in Psychology of Rio Grande do Norte. Therefore, the bibliographical references contained in education plan of subjects linked to the common center of the courses, which were taught in 2011 in three Psychology courses of the state, were focused. The analysis of the material was based on bibliographical and contextual aspects of the production, such as year, nationality, type of material, authorship (including the link of authors to PPGs), structuring axis of the subject in which it was mentioned, among others. The results showed that the national production is predominant in all courses, and they are, mostly, originated from PPGs of Psychology. Among these, the publications resulted from programs in Southwest, with emphasis to PUC-SP, are recent (mostly from 2000s) and they are predominantly composed by books (organizations and full texts). Regarding the distribution of Psychology PPGs production by the structuring axes, it is observed that it surpasses the foreign production only in axis C (procedures of scientific investigation and professional practice) and axis F (professional practices). Accordingly, it is concluded that Psychology production is found in graduation, sharing space with foreign publications and from other areas of knowledge. On the one hand, this is positive, by taking into account the importance of several foreign works and from other fields to build the knowledge in Psychology; on the other hand, it shows that the production from this area is inserted in graduation in a less significant way than its growth, which points out the existence of gaps in the development of some investigative domains from national Psychology

A percepção de suporte organizacional dos novos servidores da Universidade Federal do Rio Grande do Norte

This work deals with organizational support perception-OSP. This is done considering staff global beliefs, value of their contributions, care and well being related of individuals in an organization. These issues has been have been present in many researches since the 80s. It is important to analyze this matter considering all the changes that occurred nationally and internationally in the academic environment, characterized as being diversified in academic and managerial level. This occurs especially in Brazil since Federal Universities and their agents have suffered impact and restructuring. The research has emphasized the technical-managerial as well as professor staff level at Universidade Federal do Rio Grande do Norte aiming to deal with their unsatisfaction upon social political support. Thus, there was participation of 259 staff that were admitted from 2003 to 2005 in many sectors and units of the university. These subjects were submitted to a social and demographical query through an application of a scale of organizational support perception-OSP. Descriptive and multivariate analysis was done considering factors (management style of higher command), material support, wages, work overload, social support at work and ascending levels). Results show that there a hierarchy of the analyzed factors, the factor social support at work as being the first one with 3,31%, the factor management style of the higher command in second with 3,30%, then followed by the factor social support at work with 2,92%, in a sequence the factor material support, factor overload with 2,49% in the fourth position, and in the fifth place, the factor ascending with an average of 2,33% and in last the factor wages with 2,20%. It is concluded that the factors related to the more positive attributions of the OSP (social support at work), in a sequence material support opposing from the most negative factors of the OSP (wages, overload, ascending) reveal a reality that points out that the OSP is very much related to the individualized actions of the members of the organization (leader-member-group) rather than on structure and institutionalized actions carried out at UFRN

Saúde mental em operadores de petróleo do Rio Grande do Norte

The importance of identifying the consequence of the hours worked on people in society has been well recognized within Organizational and Work Psychology. From this point of view, the present research had the objective of analysing the effects of work regimes on the mental health of petroleum operators of Petrobrás. The sample totaled 144 subjects, corresponding to 27% of the work population. The mental health of the participants was evaluated using the following instruments of measurement: QSG-12, Scale of self-esteem, Scale of Positive and Negative Affections and the Scale of Valuable Attributes of IMST, each representing an empirical factor used to indicate and measure the five dimensions of mental health. The subjects perceptions of their work regime and the rest of their conditions of work were evaluated using scales of descriptive attributes of IMST, by applying a semi-structured questionnaire and by use of interviews. A socio-demographic file was used to collect information related to the biographical and socio-occupational profile of the worker sample. The answers to the questionnaire were inserted into the data bank of SPSS (Statistical Package for Social Science), for statistical analysis, and the interviews were analised based on the technique of Contents Analysis recommended by Bardin (1995). The main results revealed that one third of the worker sample were tense; however, the mental health of the majority was preserved. Cluster Analysis applied to the group of seven factors which measured the five dimensions of mental health identified four profiles of psychological well-being shared between members of the sample. It was observed that the people working in the system of Continuous Shift Alternation (TIR) and in the system of Pre-advising tended to present balanced and satisfactory profiles, while the ones which worked in the Administrative Field tended to present anxious and oscillating profiles, and thus were more affected psychologically. These were also the ones that also perceived the more negative aspects of their laborious conditions (reduced chances of self-improvement, physically stressful and financial resources below expectations with which to supply family and personal necessities. In agreement with the ecological model formulated by Warr (1987), the present study concluded that the positive and negative effects on the psychological well-being tended to occur as a consequence of the perceptions the petrol operators developed to face their work conditions

Determinação da composição química do molusco anadara notabilis encontrado em Galinhos no Rio Grande do Norte

Tendo em vista a grande biodiversidade existente no litoral brasileiro, onde muitas espécies ainda são pouco conhecidas, inclusive sob o aspecto nutricional, e considerando que os moluscos bivalves se constituem em um recurso natural de boa aceitação pela população mundial, escolheu-se o molusco bivalve Anadara notabilis, por não ter sido encontrado na literatura nenhuma informação nutricional ou toxicológica sobre ele e devido seu tamanho ser bem maior que outras espécies de moluscos mais popularmente encontrados nessa região. Foram determinados neste trabalho teores de umidade, cinzas, proteínas, macro e microminerais, além de íons metálicos de importância toxicológica. Todas as determinações seguiram as Normas Analíticas do Instituto Adolfo Lutz. A determinação de proteína foi realizada pelo método de Kjeldahl. Todos os íons metálicos foram determinados por espectroscopia de emissão ótica com plasma indutivamente acoplado (ICP-OES) descrito pela metodologia USEPA 6010C. Os resultados mostraram que a Anadara notabilis pode ser introduzida na alimentação dos seres humanos, tendo em vista sua riqueza mineral. Merecem destaque entre os macronutrientes o magnésio e o fósforo que apresentaram os respectivos valores em mg/kg 918,7 e 586,7. Com relação aos micronutrientes destacam-se o ferro presente com 586,7 mg/kg e o Zinco com 12,31 mg/kg. Não foi encontrado índice elevado de metais contaminantes para este molusco, o que impediria seu consumo, apenas o cromo esta 0,7 mg/kg acima do valor estabelecido pela legislação brasileira. Os resultados obtidos certamente serão muito úteis em futuras pesquisas nutricionais e para construção de uma tabela brasileira de composição química de alimentos
