Efeito da intensidade luminosa no desenvolvimento larval do camarão-da-amazônia, Macrobrachium amazonicum

The effects of four light intensities (0; 2.8 +/- 0.9; 5,5 +/- 1,8 e 7,8 +/- 2,5 mu mol s(-1) m(-2), about 136.5 +/- 87.5; 273 +/- 43.8 e 390 +/- 125 lux, respectively) on survival, productivity, weight gain and larval development of Macrobrachium amazonicum were investigated. Four treatments with three replicate tanks were evaluated. Newly hatched larvae were held in black tanks (80.2 +/- 0.6 larvae L(-1)) filled with 50-L-brackish water (salinity of 10), in a recirculating system. Tanks were covered with shadow cloth allowing 35% and 70% light, respectively, to reach light intensities of 2.8 +/- 0.9 and 5.5 +/- 1.8 mu mol s(-1) m(-2) at the water surface. Complete absence of light (0 mu mol s(-1) m(-2)) was obtained covering the tanks with opaque black plastic, and full-light condition used no covering (7.8 +/- 2.5 mu mol s(-1) m(-2)). Observations showed that the survival rate was not affected by light intensity. Productivity and weight gain were higher under 7.8 +/- 2.5 mu mol s(-1) m(-2) light intensity than under 0 and 2.8 +/- 0.9 1 mu mol s(-1) m(-2) intensities (P<0.05). The larval development index was similar among the treatments under the different light intensities. However, from stage VII this index was increased slightly in the treatment under 7.8 +/- 2.5 mu mol s(-1) m(-2) light intensity. In conclusion, light intensity affects larval development of M. amazonicum. Values as high as 7.8 mu mol s(-1) m(-2) (about 390 lux) improve the larval performance by enhancing development, productivity and weight gain compared to lower values.

Uso de bandejas de alimentação na fase de engorda do camarão-da-Amazônia Macrobrachium amazonicum (HELLER, 1862)

The aim of this experiment was to evaluate the hypothesis that the M. amazonicum prawns accept feeding in trays. Six ponds were stocked with 10 juveniles II (1.2 +/- 0.7 g) per m(2) in 02/14/2003. An entirely randomized experimental design with 2 treatments (feeding in trays or feeding to the throw) and 3 replicates was used. Prawn average weight, survival, productivity, and physical and chemical variables of the water were compared between treatments using "t" test of Student. Average weight, survival and productivity were, respectively, 7.2 +/- 0.3 g, 46.8 +/- 7.8% and 335 +/- 45 kg/ha in feeding tray treatment and 6.8 +/- 0.1 g, 85.8 +/- 5.2% and 586 +/- 42 kg/ha in feed to the throw treatment. Survival and productivity differed significantly (p<0.5), while that average weight didn't differ significantly. M. amazonicum needs to use further number of trays per area, possibly due to territorial and aggressive behavior.

Densidade de estocagem para produção de Acará-bandeira em viveiros escavados em policultivo com Camarão-da-amazônia

The aim of this study was to evaluate the production of Freshwater Angelfish (Pterophyllum scalare) in different stocking densities in cages polycultured with Amazon River Prawn (Macrobrachium amazonicum). Four treatments were evaluated (1; 2; 3 and 4 fish. 10 L(-1)) using two ponds and 24 experimental units. Water quality parameter reached adequate levels for the species. Production data were submitted to ANOVA. Fish produced in the lowest density showed higher values of final weight and standard length, and lower total biomass in comparison with the others treatments. Feed conversion rate, survival, batch uniformity and body factor were not significant different among treatments. The highest density tested produced more fish and gross yield than the others treatments. The density 20 fish. 10L(-1) is recommended to produce Freshwater Angelfish in cages polycultured with Amazon River Prawn.

Desenvolvimento, sustentabilidade e conservação da biodiversidade na amazônia: a produção familiar agroextrativista em áreas protegidas no sul do amapá

The establishment of Extractivism and Sustainable Development Reserves comes from an amazon forestry people resistance initiative. It means an option of natural resources management as protected areas for agroextractivism purposes. According to the institutional point of view, these lands, called Conservation Unity for Sustainable Exploration, belong to the government which grants the usufruct rights to the agroextractivist families under a sharing territory administration agreement among government and rural communities. The main roles of these lands are both: to improve the dwellers wellbeing, and protecting the local biodiversity. Additionally, they also represent the start of this thesis theme entitled Development, sustainability, and biodiversity conservation in the Amazon region: the use of protected areas for agroextractivism domestic yield in south of Amapá state with the objective of analyzing the performance that each territory has been reaching in terms of the attributions proposed at the beginning, when they were created. Social, economics, and environment changes that occurred in the agroextractivist areas have been evaluated from two selected test sites, named Rio Cajari Extractivist Reserve and Rio Iratapuru Sustainable Reserve, both, localized in the south of Amapá state

Trabalho, educação e desenvolvimento: o norte da educação da CUT na Amazônia

This thesis is the result of a bibliographic and field research, with the purpose to answer in what way the process of education developed by the CUT, expressed in the experience of the Project Vento Norte, developed in the Amazônia has colaborated in the sense of the possibility of a articulation between work, education, and develpoment. The bibliographic reasearch was based in the studies of theoreticals like Gadotti (1999), Marx (1998, 1998a), Pochman (2002), Brandão (1985, 2002), Adorno (1999, 2000), Horkeimer (1976), reseachers that in the process of their studies, thinked about the theme, related to work, to education and to developement. The field research was done by the intervews with CUT s educators and managers from the states of Acre, Amazonas, Amapá, Pará, Rondônia and Roraima. The thesis s process of elaboration is done in a cobweb of elements articulated to socioculture values from the habitat of amazônia people. The conclusions point to us that the hypothesis of the CUT, by the Project Vento Norte, develops a propose of education that articulates Work, Education and Development that is confirmed. But, the partiality of the project is presented by the limitations of the CUT s possibility in continuation of the project. Thats why the thesis suports the idea of the project and it consolidation in the Amazônica Region, by the conception of the syndicate managers and educators

Comportamento de atributos físicos de um Latossolo Amarelo sob agroecossistemas do Amazonas

O desmatamento da floresta tropical da Amazônia e a utilização do solo para fins agrícolas potencializam sua degradação física, química e biológica, quando realizados de forma inadequada. Este estudo teve o objetivo de avaliar o efeito de sistemas de uso e manejo de um Latossolo Amarelo, muito argiloso, mediante avaliações de atributos físicos determinados nas profundidades de 0,0-0,2 e 0,2-0,4 m, em área da Universidade do Amazonas, Manaus (AM). Os sistemas de uso e manejo foram: milho, laranja, pupunha, guaraná, pastagem, capoeira e floresta. Nos sistemas com milho, laranja, pupunha e pastagem, foram realizados o desmatamento, a queima e as operações de preparo e cultivo mecanizados. Foram avaliados a composição granulométrica, o grau de floculação da argila, o teor de matéria orgânica, a densidade de partículas, a densidade do solo, a porosidade total, a macro e microporosidade, e a infiltrações inicial e básica. Utilizou-se o delineamento experimental inteiramente casualizado, com três repetições. Os agroecossistemas, em ordem crescente: capoeira, guaraná, milho, laranja, pupunha e pastagem induziram uma degradação dos atributos físicos do solo cultivado em relação ao de floresta, quantificada pelos maiores valores de densidade do solo e menores de macroporosidade, infiltração de água e matéria orgânica.

Desenvolvimento e projeto de colhedora de babaçu (Orbignya phalerata Mart.) para agricultura familiar nas regiões de matas de transição da Amazônia

O babaçu (Orbignya phalerata) é uma típica palmeira das matas de transição dos ecossistemas Amazônia/Cerrado e Amazônia/Caatinga, sendo de grande importância econômica, social e ambiental nestas regiões. Os produtos advindos dos babaçuais possibilitam renda para uma das camadas mais pobres da região amazônica e um dos entraves para a obtenção eficiente destes produtos é a colheita dos cocos de babaçu, que atualmente se faz no sistema extrativista. O objetivo deste trabalho foi realizar o desenvolvimento e projeto de uma colhedora de babaçu adaptável ao ambiente de trabalho da agricultura familiar e as características das matas de transição amazônicas. Para tal foram realizados estudos de literatura que nortearam as decisões e simplificações de projeto, assim como foram realizados os cálculos e desenhos da nova colhedora. O projeto foi realizado através de ferramentas de engenharia que apresentaram como resultados o memorial de cálculo que descreve o caminho técnico para o dimensionamento dos elementos constituintes da colhedora e a partir destes os desenhos detalhados dos elementos da nova máquina. Pelos desenhos detalhados suas considerações e decisões concluí-se que a colhedora de babaçu apresenta-se passível de ser construída com materiais nacionais de baixo custo, além de fácil operação, manutenção e com mínimo efeito sobre os babaçuais naturais.
