Prospects for fish culture in char areas of Bangladesh

Fish production is considered in the barren chars or sandy land masses created through siltation along river banks and deltas in Bangladesh. The prospects for fish culture in ponds and cages or pen culture in rivers and canals are examined. The socioeconomic implications of fish culture as a livelihood source for communities living in char areas are also discussed.

Ressonâncias de heróis e reis medievais na (re)construção dos personagens da Pedra do Reino por Ariano Suassuna

A presente tese está calcada na análise da obra de Ariano Suassuna, o Romance dA Pedra do Reino e o príncipe do sangue do vai-e-volta, considerado pelo autor como a sua obra maior e, a princípio, o primeiro volume da trilogia A maravilhosa desaventura de Quaderna, o decifrador, e no primeiro volume da segunda parte da trilogia, O rei degolado ao Sol da Onça Caetana. O trabalho consiste, fundamentalmente, em examinar o diálogo estabelecido entre a obra de Suassuna com textos representativos da tradição literária ocidental, mais propriamente com os que remontam ao medievo. Para isso, fez-se um recorte nas relações que o romance trava com a matéria cavaleiresca, principalmente com a Demanda do Santo Graal, na sua estrutura e no desenho psicológico e moral dos personagens, notadamente de Sinésio, que encarna o mito do herói prometido, cujos paradigmas se assentam na figura lendária do Rei Artur, além de Galaaz, e na histórica de D. Sebastião, o rei desaparecido de Portugal. Sabe-se que esses reis e heróis míticos, considerados salvadores, uma vez que retornariam para restituir ao povo a dignidade e a liberdade perdidas, povoaram o imaginário ibérico e chegaram ao Brasil trazidos pelos colonizadores europeus. Dessa forma, a cultura popular do Nordeste brasileiro é povoada de histórias e lendas eternizadas e recriadas no folclore da região e na literatura de Cordel. Mas, ao lado do messianismo, outro aspecto faz-se notório nos personagens de Suassuna: a crueldade. E este tema, bem como o nome do personagem D. Pedro Dinis Quaderna, remete-nos para a história de alguns reis ibéricos da Idade Média: Pedro de Portugal e Pedro de Castela, que serão revisitados à luz da Crônica de D. Pedro de Fernão Lopes, no intuito de observar-se o diálogo com esta estabelecido por Suassuna, direta ou indiretamente

Status, Constraints, and Opportunities for Salmon Culture in the United States: A Review

A Review of World Salmon Culture

World farmed salmon production reached 145,000 metric tons (t) in 1988 and an estimated 217,000 t in 1989. The latter figure is comparable to the U. S. annual salmon catch (about 250,000 t) and is approaching one-third the size of the world wild salmon catch (about 700,000 t). The rapid expansion of farmed salmon supplies in the late 1980's has led to sharp price decreases. Lower prices have forced some farmers out of business, but at the same time, a large number of farmers first began harvesting salmon on a commercial scale as the 1980's ended. Farmed salmon production could exceed 270,000 t in 1990.
