Soft Flesh in Sablefish, Anoplopoma fimbria, of Southeastern Alaska: Relationships with Depth, Season, and Biochemistry

The condition of soft-textured flesh in commercially harvested sablefish, Anoplopoma fimbria, from southeastern Alaska was investigated by National Marine Fisheries Service (NMFS) scientists from the Alaska Fisheries Science Center’s Auke Bay Laboratories (ABL) in Alaska and the Northwest Fisheries Science Center in Seattle, Wash. Sablefish were sampled by longline, pot, and trawl at five sites around Chichagof Island at depths of 259–988 m in the summer of 1985 and at depths of 259–913 m in the winter of 1986. At the time of capture and data collection, sablefish were categorized as being “firm” or “soft” by visual and tactile examination, individually weighed, measured for length, and sexed. Subsamples of the fish were analyzed and linear regressions and analyses of variance were performed on both the summer (n = 242) and winter (n = 439) data for combinations of chemical and physical analyses, depth of capture, weight vs. length, flesh condition, gonad condition, and sex. We successfully identified and selected sablefish with firm- and soft-textured flesh by tactile and visual methods. Abundance of firm fish in catches varied by season: 67% in winter and 40% in summer. Winter catches may give a higher yield than summer catches. Abundance of firm fish catches also varied with depth. Firm fish were routinely found shallower than soft fish. The highest percentage of firm fish were found at depths less than 365 m in summer and at 365–730 m in winter, whereas soft fish were usually more abundant at depths greater than 731 m. Catches of firm fish declined with increasing depth. More than 80% of the fish caught during winter at depths between 365 and 730 m had firm flesh, but this declined to 48% at these depths in summer. Longlines and pots caught similar proportions of firm and soft fish with both gears catching more firm than soft fish. Trawls caught a higher proportion of soft fish compared to longlines and pots in winter. Chemical composition of “firm” and “soft” fish differed. On average “soft” fish had 14% less protein, 12% more lipid, and 3% less ash than firm fish. Cooked yields from sablefish with soft-textured flesh were 31% less than cooked yields from firm fish. Sablefish flesh quality (firmness) related significantly to the biochemistry of white muscle with respect to 11 variables. Summer fish of all flesh conditions averaged 6% heavier than winter fish. Regulating depth of fishing could increase the yield from catches, but the feasibility and benefits from this action will require further evaluation and study. Results of this study provide a basis for reducing the harvest of sablefish with soft flesh and may stimulate further research into the cause and effect relationship of the sablefish soft-flesh phenomenon.

Size-composition of Annual Landings in the White Shrimp, Litopenaeus setiferus, Fishery of the Northern Gulf of Mexico, 1960–2006: Its Trend and Relationships with Other Fishery-dependent Variable

The potential for growth overfishing in the white shrimp, Litopenaeus setiferus, fishery of the northern Gulf of Mexico appears to have been of limited concern to Federal or state shrimp management entities, following the cataclysmic drop in white shrimp abundance in the 1940’s. As expected from surplus production theory, a decrease in size of shrimp in the annual landings accompanies increasing fishing effort, and can eventually reduce the value of the landings. Growth overfishing can exacerbate such decline in value of the annual landings. We characterize trends in size-composition of annual landings and other annual fishery-dependent variables in this fishery to determine relationships between selected pairs of these variables and to determine whether growth overfishing occurred during 1960–2006. Signs of growth overfishing were equivocal. For example, as nominal fishing effort increased, the initially upward, decelerating trend in annual yield approached a local maximum in the 1980’s. However, an accelerating upward trend in yield followed as effort continued to increase. Yield then reached its highest point in the time series in 2006, as nominal fishing effort declined due to exogenous factors outside the control of shrimp fishery managers. The quadratic relationship between annual yield and nominal fishing effort exhibited a local maximum of 5.24(107) pounds (≈ MSY) at a nominal fishing effort level of 1.38(105) days fished. However, annual yield showed a continuous increase with decrease in size of shrimp in the landings. Annual inflation-adjusted ex-vessel value of the landings peaked in 1989, preceded by a peak in annual inflation-adjusted ex-vessel value per pound (i.e. price) in 1983. Changes in size composition of shrimp landings and their economic effects should be included among guidelines for future management of this white shrimp

Length-weight Relationships of Dolphinfish, Coryphaena hippurus, and Wahoo, Acanthocybium solandri: Seasonal Effects of Spawning and Possible Migration in the Central North Pacific

Weight-on-length (W-L) relationships for 2,482 dolphinfish, Coryphaena hippurus, and 1,161 wahoo, Acanthocybium solandri, were examined. Data on fork length, whole (round) weight, and sex were collected for dolphinfish at the Honolulu fish auction from March 1988 through November 1989. Unsexed weight and length data for wahoo were collected at the auction from July 1988 through November 1989. We also used sex specific weight and length data of 171 wahoo collected during 1977–1985 research cruises for analysis. Coefficients of W-L regressions were significantly different between the sexes for dolphinfish. Coefficients did not significantly differ between the sexes for wahoo based on research cruise data. In a general linear model evaluating month as a categorical factor, month was significant for female dolphinfish, male dolphinfish, and wahoo with sexes pooled. W-L and length-on-weight (L-W) relationships were fitted by nonlinear regression for all dolphinfish, female dolphinfish, male dolphinfish, and all wahoo sexes pooled. W-L relationships for monthly samples of female dolphinfish, male dolphinfish, and all wahoo with sexes pooled were also fitted by nonlinear regression. Predicted mean weight at length for wahoo was highest at the beginning of the spawning season in June and lowest after the spawning season in September. Maximum and minimum predicted mean weight at length for both sexes of dolphinfish did not correspond with the peak spawning period (March–May). Plausible migration models in conjunction with reproductive behavior were examined to explain the variability in monthly predicted mean weight at length for dolphinfish.

Um estudo sobre a vivência da gravidez tardia

Atualmente, no Brasil e no mundo, há um aumento do número de mulheres que postergam a gravidez para após os 35 anos em função da estabilidade profissional, espera de um relacionamento, infertilidade, incerteza sobre o desejo de ser mãe. Independente do motivo, na proporção em que acontece, o aumento do número de mulheres que vivenciam a gravidez tardia configura-se um fenômeno irreversível, que só tende a aumentar. Esta pesquisa teve como objeto a vivência da gravidez tardia e seus objetivos foram: descrever a vivência da mulher que engravida após os 35 anos e analisar a vivência sob a perspectiva de gênero e vulnerabilidade. Estudo descritivo, com abordagem qualitativa, tendo como técnica de coleta de dados a entrevista aberta, realizada com 16 mulheres no ciclo gravídico puerperal, com idade entre 36 e 48 anos, internadas em duas maternidades públicas, cenários da pesquisa, situadas no município do Rio de Janeiro. Foram observados os princípios da Resolução n 466 de 12 de dezembro de 2012 do Conselho Nacional de Saúde. Realizou-se análise temática dos dados categorizados. O estudo mostrou que fazem parte da vivência da mulher que engravida após os 35 anos, o desejo de ser mãe; aspectos positivos relativos à idade, maturidade, discernimento, profissão mais definida, aspectos que interferem favoravelmente na relação com a criança; e como aspectos negativos, cansaço, discriminação geracional e problemas de saúde. A espiritualidade, religiosidade e rede de apoio fortalecem a mulher para o enfrentamento de possíveis dificuldades. O planejamento familiar mostrou-se inexistente para as participantes e conclui-se que ao postergar a gravidez a mulher reduz a sua prole. Os resultados evidenciaram que para o planejamento da assistência o enfermeiro ou profissional de saúde deve trabalhar em equipe e conhecer o risco e a vulnerabilidade (individual, social e programática) da sua cliente. Deve considerar a situação socioeconômica e aspectos da vida familiar e afetiva, profissional, jornada de trabalho, trabalho doméstico, rede de apoio e acessibilidade aos serviços. A fim de detectar aspectos individuais, coletivos e contextuais que aumentam a suscetibilidade da cliente. A escuta qualificada é a primeira providência para identificar as necessidades e singularidades das clientes e definir a estratégia de cuidados.

A formação de docentesdiscentes atravessada pelas imagens de professores no cinema como questão curricular.

Compreendendo as imagens e as narrativas como personagens conceituais (DELEUZE, GUATTARI, 1992), neste trabalho, desenvolvi temáticas presentes ou estimuladas com os filmes com personagens de professores e cotidianos escolares. Exibições de filmes, seguidos de conversas entre estudantes do curso de Pedagogia presencial da Universidade do Estado do Rio de Janeiro (campus Maracanã) permitiram a produção do corpus dessa pesquisa, que buscou mapear os mundos culturais, as redes de conhecimentos e significações tecidas por esses estudantes. Assim, as conversas têm sido uma importante metodologia nas pesquisas nos/dos/com os cotidianos, porque segundo Alves (2012), são através delas que trocamos saberesfazeres nos mais variados cotidianos. Contando também com Certeau (1994, 2009), Giard (2009), Maturana (2001, 1998), entre outros, busquei compreender como os cotidianos são organizados através da oralidade, pois na perspectiva de Certeau, Alves e Garcia mapear as ações sujeitas ao esfarelamento, como são características das táticas (CERTEAU, 1994) dos praticantespensantes (OLIVEIRA, 2012) só é possível através das narrativas. Assim, as imagens do cinema permitiram as vivências mais variadas, mostrando sua potência em proporcionar aproximações com situações inusitadas para muitos espectadores, ou ainda, situações de espaçostempos distantes. Os teóricos com quem busquei dialogar acerca dos usos e consumos de imagens audiovisuais foram Machado (2001, 2007), Barbero (2000, 2007) e Deleuze (2005) apostando que intrínseco a esses consumos estariam também implícitos suas subversões e processos formativos. Impactante tornou-se para o grupo envolvido na pesquisa, foi o entendimento dos clichês como potência para o pensamento. Assim, recorrer às imagens dos filmes foi uma forma de abordar as questões que atravessam o chão das escolas e cursos de formação de professores, uma vez que surgiram temáticas tocantes aos cotidianos escolares e saberesfazeres pedagógicos, além daqueles mostrados pelos filmes. Assim, diversas temáticas surgiram entre cinco principais eixos, em torno das relações: entre os docentes e autoridades; entre os discentes; entre os discentes e os docentes; entre os docentes; e os usos dos artefatos culturais e tecnológicos. Todas essas questões envolveram os currículos como sendo tecidos em redes de significações e conhecimentos a partir das compreensões de Alves (2010, 2012a), Carvalho (2012) e Castells (2013). As diferenças que encontramos nos diversos espaçostempos, foram abordadas a partir da presença dos praticantespensantes de várias religiões nas escolas, desenvolvidas com as pesquisas de Caputo (2012), acerca das diferenças nas relações cotidianas entre discentes e docentes, com os trabalhos de Hall (2012), Silva (2012) e Gilroy(2001), pude abordar as tessituras identitárias. Além disso, as pesquisas de Nóvoa (1995), Teixeira (2008) e Müller (2008) foram pertinentes para a compreensão da formação do corpo docente brasileiro e seus atravessamentos de características de cor e gênero. Assim, nesse trabalho, desenvolvo a ideia de que as diferenças nos cotidianos potencializam e ampliam as redes de conhecimentos e significações, bem como os currículos praticadospensados (OLIVEIRA, 2012) nas escolas.

A Rede da Dança: uma cartografia em movimento

A pesquisa da Rede da Dança é uma proposta de abordagem em rede, do ponto de vista da rede de Bruno Latour, para o fenômeno da dança contemporânea. Inicialmente a proposta era de pensar a dança que acontece na internet, conseqüência do impacto da tecnologia online na produção artística de dança. Mas se expandiu e se reposicionou em uma rede de relações que acontece nos diversos procedimentos em que a prática de dança se implica, que não é apenas o fazer artístico, e que se torna potente no território do entre. A pesquisa tem por objetivo, no entanto, investigar as relações que conectam a rede da dança, mais do que uma análise de dança contemporânea como um gênero de arte. Para isso utilizamos imagens de redes, que são na verdade entradas na pesquisa através de exemplos de práticas, iniciativas e produções em que as relações estão evidentes, em que os processos são priorizados em vez dos resultados. Neste aspecto, a colaboração ganhou relevância ao longo das narrativas das imagens e se apresentou como força mobilizadora das relações que acontecem na rede da dança hoje. Por fim, nossa pesquisa é apresentada como um exercício cartográfico, uma descrição do tipo etnográfica, que implica em deixar o objeto falar, além de utilizar narrativa de primeira pessoa, diários de campo, uma pesquisa que se constrói com o objeto e não sobre.

Transforming aquatic agricultural systems towards gender equality: a five country review

Aquatic agricultural systems (AAS) are systems in which the annual production dynamics of freshwater and/or coastal ecosystems contribute significantly to total household income. Improving the livelihood security and wellbeing of the estimated 250 million poor people dependent on AAS in Bangladesh, Cambodia, the Philippines, the Solomon Islands and Zambia is the goal of the Worldfish Center-led Consortium Research Program (CRP), “Harnessing the development potential of aquatic agricultural systems for development.” One component expected to contribute to sustainably achieving this goal is enhancing the gender and wider social equity of the social, economic and political systems within which the AAS function. The CRP’s focus on social equity, and particularly gender equity, responds to the limited progress to date in enhancing the inclusiveness of development outcomes through interventions that offer improved availability of resources and technologies without addressing the wider social constraints that marginalized populations face in making use of them. The CRP aims to both offer improved availability and address the wider social constraints in order to determine whether a multi-level approach that engages with individuals, households and communities, as well as the wider social, economic and political contexts in which they function, is more successful in extending development’s benefits to women and other excluded groups. Designing the research in development initiatives to test this hypothesis requires a solid understanding of each CRP country’s social, cultural and economic contexts and of the variations across them. This paper provides an initial input into developing this knowledge, based on a review of literature on agriculture, aquaculture and gender relations within the five focal countries. Before delving into the findings of the literature review, the paper first justifies the expectation that successfully achieving lasting wellbeing improvements for poor women and men dependent on AAS rests in part on advances in gender equity, and in light of this justification, presents the AAS CRP’s conceptual framew

Building coalitions, creating change: an agenda for gender transformative research in development Workshop Report 3-5 October 2012, Penang, Malaysia

There is compelling evidence that increased gender equity can make a significant contribution towards alleviating poverty and increasing food security. But past efforts to integrate gender into agricultural research and development practice have failed to address the inequalities that limit women’s access to agricultural inputs, markets, resources and advice. A Gender Transformative Approach (GTA) goes beyond just considering the symptoms of gender inequality, and addresses the social norms, attitudes, behaviors and social systems that underlie them. The CGIAR Research Program on Aquatic Agricultural Systems (AAS) has placed the GTA at the heart of its gender strategy. This workshop was an opportunity for researchers, practitioners and donors working in this area to address the challenge of how to translate this approach into actual research and development practice. The workshop recommended that a GTA should be adopted alongside, not instead of, existing efforts to reverse gender disparities in resources, technologies and markets. It is through this pairing that improved social and material outcomes can be achieved, with the expectation that when achieved together, both types of outcomes will be more lasting than if achieved individually.
