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.

A contribuição do hip-hop para a construção de pedagogias de resistência e de transformação social

O presente estudo entende que as várias formas de resistência popular somente podem arrancar da luta cotidiana os caminhos para a superação de todo tipo de exploração e opressão se assumirem um caráter pedagógico e contra-hegemônico. No caso do movimento hip-hop, tal caráter se expressa na elaboração de formas de resistência que lançam mão da cultura própria das comunidades pobres das grandes cidades para organizar formas concretas de protesto, organização e luta. Para responder às indagações colocadas por esta hipótese escolheu-se como objeto de estudo a atuação do coletivo fluminense de hip-hop Lutarmada, que participa das ações dos movimentos sociais do estado e em nível nacional. Suas intervenções por meio do rap, do grafite e do break unem arte, cultura, atividades de formação e conscientização contra-hegemônica que procuram apontar caminhos rebeldes e emancipadores para a juventude negra

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

This paper reviews and analyzes the major factors constraining the development of salmon culture in the United States. A brief review of economic factors in the seafood sector contributing to the industry's recent growth is offered, and the present status of the major producing regions is summarized. The major constraints, which include marketing problems, policy and regulatory constraints, production costs, disease, financiing, and environmental uncertainty, are discussed, followed by recommendations for improving the industry's development.

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.

Determinações teórico-políticas dos sistemas de avaliação da educação superior: questões da Educação

O presente estudo propôs a identificação das determinações da avaliação da educação superior, com recorte na formação em Educação Física, utilizando-se das categorias do materialismo histórico e dialético. As ideologias do Capital Humano e do Capital Social e seus teóricos serviram como mediadoras dessa análise. Para tanto, utilizamo-nos do fenômeno da globalização e seus conseqüentes reflexos na sociedade brasileira em geral e na educação superior em particular. Os modelos de avaliação foram aqui examinados até a atualidade, bem como seus desdobramentos na formação em Educação Física e seu respectivo campo de trabalho, com algumas experiências ocorridas em nosso território. Tendo como caminho as propostas avaliativas, os aspectos históricos da constituição da Educação Física, os instrumentos de avaliação atuais, as avaliações internas produzidas na UFRJ e UFF e o aprofundamento das ideologias do CH e do CS, acreditamos ter evidenciado o fio condutor do estabelecimento de uma cultura conformadora e justificadora da exploração da população pelo capitalismo que acaba por ser abraçada por parcelas de professores de Educação Física quando se alinham de forma irrefletida aos modelos de avaliação. Apontamos a possibilidade de uma ação contra-hegemônica por um caminho politizador no interior das instituições escolares, em todos os seus níveis e com todos os seus atores, passando pelos movimentos sindicais e chegando principalmente à Universidade

Gunnislake Fish Counter. Annual Report 1999

This is the Gunnislake Fish Counter, Annual Report 1999 produced by the Environment Agency South West Region on March 2000. The report presents the daily upstream counts of migratory salmonids recorded at Gunnislake Weir fish counting station (SX 435 713) situated on the River Tamar in 1999. The counter data contained within this report covers the period of the commercial migratory salmonid net buy-back scheme and the implementation of the National Spring Salmon Byelaws. The fish counter at Gunnislake is a resistivity based system (Logie 2100A – Aquantic limited) and is installed in the fish pass on the Cornish bank of the River Tamar at the head of the tide. The minimum salmon count for 1999 was 2691. The run pattern observed for salmon and sea trout in 1999 was generally consistent with that of previous years. However, the total combined annual count of salmon and sea trout migrating upstream on the River Tamar in 1999 was 25% higher than the 5 year average (1994 - 1998).

Restormel Fish Counter Annual Report 1999

This is the Restormel Fish Counter, Annual Report 1999 produced by the Environment Agency South West Region on March 2000. The report presents the daily upstream counts of migratory salmonids recorded at Restormel Weir counting station (SX 107 613) River Fowey in 1999. The counter data covers the period of the commercial migratory salmonid net buy-back scheme, which was in operation between March and June 1999. The fish counter is a resistivity based system (Logie 2100 A - Aquantic limited) and operates over all three channels of the weir at Restormel. The minimum salmon count estimate was 497, and the 1999 upstream count for sea trout was 6590. The run pattern observed for salmon and sea trout in 1999 was generally consistent with that of previous years. Flows on average were half those of 1998 during September, October, and November.
