Blue marlin, Makaira nigricans, tag and recapture data are summarized for 1954-1988. During this period, 8,447 fish have been tagged and only 30 (0.35 percent) have been returned. Results of the tagging program indicate that blue marlin not only travel considerable distances (7,OOO km from the U. S. Virgin Islands to the Ivory Coast of West Africa), but have remained at large for up to 8 years. Seasonal movements, however, are difficult to determine accurately.

O município do Rio de Janeiro, desde sua fundação luta com o grave problema de abastecimento de água. Com o passar do tempo todas as pequenas captações no entorno da cidade foram exauridas tanto em termos de quantidade como em qualidade, afetadas pela poluição decorrente do lançamento de efluentes in natura. Solução foi a busca por novas fontes de abastecimento em outros municípios. Atualmente 80% (oitenta por cento) do abastecimento da região metropolitana do Rio de Janeiro, RMRJ, é proveniente de uma única fonte: o rio Guandu. Isto foi possível devido à transposição da bacia do rio Paraíba do Sul para o rio Guandu ocorrida na década de 50. Esta fonte essencial de abastecimento, onde foi construída a maior Estação de Tratamento de Água do mundo - ETA Guandu - está à beira da exaustão. Somente uma pequena parcela de água bruta foi captada e tratada nesta última década. Visando minimizar o grave problema que já se apresenta e enquanto investimentos em novas alternativas não forem alcançados, o consumo com responsabilidade e sustentabilidade passa a ser a tônica da discussão. Neste contexto, as áreas de baixa renda do município com suas 801 favelas e mais de 1.500 loteamentos irregulares representando em 2010 aproximadamente 1/3 (um terço) da população total, consumindo de 10% a 15% de toda a produção de água tratada da região metropolitana deve ser permanentemente estimulada a contribuir com esta redução de consumo. Estudos apresentados nesta dissertação em três metodologias distintas apontam para um consumo acima da média nacional deste mesmo perfil de população. Os resultados obtidos indicam a necessidade real da redução de consumo observando, entretanto que este é um trabalho extremamente árduo e difícil uma vez que exige mudança de hábitos e a envolvimento de todos, desde a população até a Companhia de Saneamento local.

The Mekong River delta of Vietnam supports a thriving aquaculture industry but is exposed to the impacts of climate change. In particular, sea level rise and attendant increased flooding (both coastal and riverine) and coastal salinity intrusion threaten the long-term viability of this important industry. This working paper summarizes an analysis of the economics of aquaculture adaptation in the delta, focusing on the grow-out of two exported aquaculture species—the freshwater striped catfish and the brackish-water tiger shrimp. The analysis was conducted for four pond-based production systems: catfish in the inland and coastal provinces and improved extensive and semi-intensive/intensive shrimp culture.

This is the Coleopteran Fauna of ERS on the river Dane, Cheshire: a survey report produced by the Environment Agency in 2003. A comprehensive survey of the Exposed Riverine Sediment (ERS) on the River Dane, Cheshire was undertaken between mid-April and mid-June 2003. 6 locations were selected and subsequently examined to determine the importance of the constituent invertebrate fauna. Appropriate sampling techniques (i.e. pitfall trapping, hand searching and excavations) were directed towards the target group (Coleoptera). All adults from the chosen taxa were identified to species level. The relative value of the fauna was assessed using species richness, conservation status, fidelity score and a site quality index.

Os estuários são ambientes costeiros semifechados, que atuam como um sítio de troca de água e de matéria. De acordo com suas características, estuários podem exportar ou importar matéria orgânica (MO). A MO é um complexo bioquímico formado por diversos compostos orgânicos, e sua quantificação é normalmente traduzida pela quantidade de carbono orgânico total (COT), seu elemento mais abundante, tanto na forma de carbono orgânico dissolvido (COD), quanto carbono orgânico particulado (COP). Determinar a origem do carbono orgânico pode auxiliar na compreensão da dinâmica da MO, podendo ser feita com auxílio de isótopos estáveis de carbono (13C) e de nitrogênio (15N). Vila Dois Rios, é um vilarejo localizado ao sul da Ilha Grande, onde se localiza o rio Barra Grande, que possui pouca intervenção antrópica. Esse é um rio de porte pequeno, com uma mata ciliar bem preservada, representada por espécies de Mata Atlântica, com presença de manguezal, ao lado está localizado o Centro de Estudos Ambientais e Desenvolvimento Sustentável (CEADS). Foram realizadas amostragens sazonais, todas em maré de sizígia, ao longo do ano de 2012, totalizando quatro coletas trimestrais. Todas as campanhas ocorreram em uma estação fixa, na foz do rio Barra Grande. A amostragem de água foi realizada em duas profundidades, superfície e fundo, coletadas em intervalos de 30 minutos, ao longo de 25 horas, para as seguintes determinações: carbono orgânico particulado (COP), carbono orgânico dissolvido (COD) e isótopos estáveis de carbono (13C) e de nitrogênio (15N). Concomitantemente, foram medidos in situ: pH, salinidade, temperatura, oxigênio dissolvido (OD), profundidade do Disco de Secchi e medidas de fluxo. Ao fim da amostragem na Ilha Grande, o material coletado foi transportado para o Laboratório de Geoquímica Orgânica Marinha (LaGOM), na UERJ, onde foi analisado posteriormente. Durante todas as campanhas, foi observada uma maré mista, predominantemente semidiurna com desigualdade. Os resultados de temperatura e salinidade evidenciaram uma estratificação vertical em todas as campanhas. Os valores medianos de MPS foram sempre maiores no fundo em relação às amostras coletadas na superfície. O carbono orgânico apresentou maiores concentrações sob a forma dissolvida do que na particulada, variando entre as profundidades e as campanhas, sendo observadas maiores concentrações medianas, tanto de COD quanto de COP, em superfície e no fundo, na campanha de verão. As concentrações medianas de Nt observadas ao longo das três campanhas foram baixas, estando relacionadas às baixas concentrações de COP. A razão molar C/N e as isotópicas indicaram que o manguezal demonstrou ser a fonte mais abundante de COP nesse estuário. Os cálculos de fluxo indicaram que o estuário tanto importou, quanto exportou material, e apenas o COD foi importado em todas as campanhas.

This is the first River Dart Fisheries Survey produced by the Devon River Authority; which was carried out from May to October 1965. The objective was to examine the distribution and relative abundance of salmonid fish in the River Dart, in order to assess the possibility or desirability, of increasing salmon smolt production of the river by artificial propagation or other means. Description, chemical, pollution and biological conditions of the River Dart along with fisheries catches, water extraction and spawning are briefly cited. The method includes the choice of sections and sampling techniques. The results go through the number/type/class of fishes counted while the survey took place, distribution patterns within the different transects/brooks, competition between salmon parr and trout and estimations of population. The section on the discussion and recommendations is introduced by a brief explanation of the bases for the Artificial Propagation Programme and the River Dart specific case-study. The annexes contains River Dart and tributaries maps, fish size distribution tables and figures, tables with totals of salmonid fish found and population density tables.

This is the second River Dart Fisheries Survey produced by the Devon River Authority; which was carried out from April to July, 1969. The objective was to examine the distribution and relative abundance of salmonid fish in the River Dart, in order to assess the possibility or desirability, of increasing salmon smolt production of the river by artificial propagation or other means. In addition to the tributaries examined in the 1965 survey, further sections were studied on the River Hems and Holy Brook and reference should be made to the River Survey Report, 1965 for introductory information. The method includes the choice of sections and sampling techniques. The results go through the number/type/class of fishes counted while the survey took place and distribution patterns within the different transects/brooks. The discussion tries to remark the importance of understanding the differences between 1965 and 1969 surveys. The Appendix contains tables with totals of salmonid fish found and distribution sizes for each section, population density tables and a map with new surveyed sections.
